% \begin{abstract}
%   The \package{cleveref} package enhances \LaTeX{}'s cross-referencing
%   features,\linebreak[4] allowing the format of cross-references to be
%   determined automatically according to the ``type'' of cross-reference
%   (equation, section, etc.) and the context in which the
%   cross-reference is used. The formatting for each cross-reference type
%   can be fully customised in the preamble of your document. In
%   addition, \package{cleveref} can typeset cross-references to lists
%   of multiple labels, automatically formatting them according to their
%   types, sorting them, and compressing sequences of numerically
%   consecutive labels. Again, the multiple-reference formatting is fully
%   customisable.
%
%   Normally, the latest version of the \package{cleveref} package is
%   available via CTAN.\ Occasionally, slightly newer ``pre-release''
%   versions are available at \url{www.dr-qubit.org/latex.php#cleveref} a
%   little before they make their way onto CTAN.

% \section{Introduction}
% When ``clever'' is used in the name of a computer program, it usually
% indicates that the programmer is overly smug about his own
% achievements. But at the heart of the \LaTeX{} philosophy also lies the
% idea that it is clever to delegate as much of the typesetting as
% possible to the computer, in order to achieve a beautiful --- and above
% all consistent --- visual appearance.
%
% All of this probably applies to the \package{cleveref} package. Its
% goals are two-fold: to exploit all the information that \LaTeX{} can
% collect about labels as intelligently as possible (clever processing),
% allowing you to produce an attractive, consistent formatting of
% cross-references throughout your document with the minimum of effort
% (you'd be clever to use it!).
%
% The \package{cleveref} package enhances \LaTeX{}'s cross-referencing
% features by automatically formatting cross-references depending on what
% they refer to (chapter, section, equation, theorem, etc.). It can
% automatically format cross-references to multiple labels, and can sort
% lists of multiple cross-references, compresses consecutive labels into
% a reference range, and all kinds of other clever wizardry. It also does
% similar things with page references.
%
% In standard \LaTeX{}, you have almost certainly found yourself writing
% things like |Eq.~(\ref{eq1})| and |Theorems~\ref{thm1} to~\ref{thm3}|
% over and over again. Tedium isn't the only downside to this. What
% happens if you later decide you want equation references to be typeset
% as |Equation~\ref{eq1}| instead (i.e.\ without the abbreviation and
% without the parentheses)? What happens if you decide to change the
% theorem labelled |thm1| into a lemma?\footnote{Note that to allow
% \package{cleveref} to automatically infer the type of theorem, you need
% to load either the \package{ntheorem} or the \package{amsthm} package.
% See \cref{sec:non-bugs} for more details.} What if you move |thm3| so
% that it appears (and is numbered) before |thm1|, meaning that
% references to the sequence of theorems 1 through 3 should now be
% ordered |Theorems~\ref{thm3} to~\ref{thm1}| (i.e.\ the other way
% around)? What if you decide you prefer references to multiple theorems
% to be written as |Theorems~\ref{thm1}--\ref{thm3}|? Any such change
% requires you to search through the entire \LaTeX{} source of your
% document, modifying all references to equations, updating all
% references to |thm1|, re-ordering all references to |thm1| and |thm3|,
% and changing all the formatting of references to multiple theorems.
%
% The \package{cleveref} package allows you to define the format for the
% different types of cross-references once-and-for-all in the preamble of
% your document. (Of course, sane default formats are provided, so you
% only have to redefine the format if you don't like the default for a
% particular cross-reference type.) If you later decide to change the
% format of equation references, you only have to change one preamble
% definition. If you change a theorem into a lemma, you don't need to
% change any cross-references at all, because \package{cleveref} will
% automatically use the appropriate name when typesetting any
% cross-references to it. This makes it far easier to typeset
% cross-references uniformly across your whole document, as well as
% avoiding repetitively typing similar text for each and every
% cross-reference.
%
%
%
% \section{Usage}
% The \package{cleveref} package is loaded in the usual way, by putting
% the line
% \begin{quote}
%   |\usepackage{cleveref}|
% \end{quote}
% in your document's preamble. However, care must be taken when using
% \package{cleveref} in conjunction with other packages that modify
% \LaTeX{}'s referencing system (see
% \cref{sec:other_packages}). Basically, \package{cleveref} must be
% loaded \emph{last}.
%
% If you just want to get going quickly with \package{cleveref}, and come
% back later to read up on all the features it provides in more detail,
% here's what you need to do. Wherever you would previously have used
% |\ref|, use |\cref| instead. (Except at the beginning of a sentence,
% where you should use |\Cref|.) You no longer need to put the name of
% the thing you're referencing in front of the |\cref| command, because
% \package{cleveref} will sort that out for you: i.e.\ use |\cref{eq1}|
% instead of |eq.~(\ref{eq1})|. If you want to refer to a range of
% labels, use the |\crefrange| command: |\crefrange{eq1}{eq5}| produces
% |eqs.~(1) to~(5)|. If you want to refer to multiple things at once, you
% can simply throw them all into one cross-reference and leave
% \package{cleveref} to sort it out: e.g.\
% |\cref{eq2,eq1,eq3,eq5,thm2,def1}| produces%
% |eqs.~(1) to~(3) and~(5),| |theorem~5, and definition~1|. Finally, if
% you want a page reference, use |\cpageref| (and don't write ``page'' in
% front), if you want a page range, use |\cpagerefrange|, and if you want
% to refer to multiple pages, simply throw them all into a single
% |\cpageref|. Just as with |\cref| (above), \package{cleveref} will sort
% it all out for you automaticaly.
%
% \package{Cleveref} supports a number of languages other than English,
% and also supports the \package{babel} and \package{polyglossia}
% packages for those languages. Either pass the desired language as an
% option to \package{cleveref}, or pass it as a global option to
% |\documentclass|. Note that if you're writing in a language in which
% nouns decline, the |\cref| and |\cpageref| commands may be less useful,
% as they always produce the cross-reference name in the nominative
% case.\footnote{Providing separate variants of the \package{cleveref}
% commands for each noun case quickly becomes more cumbersome than just
% typing the cross-reference name by hand. Trying to determine the
% appropriate case automatically would be tantamount to solving the full
% natural-language processing problem in \package{cleveref}. Check back
% in a century or so for this feature.} In such languages, you may
% instead prefer to use the |\labelcref| and |\labelcpageref| commands.
% Unlike |\cref| and |\cpageref|, these don't produce the name in front
% of the cross-reference, so you must supply it (in the appropriate case)
% yourself. But they do still cope with multi-references, so you still
% gain some benefit from using \package{cleveref}.
%
%
%
% \section{Comparison with Other Packages}
% Given how useful automated cross-reference typesetting is, there are
% naturally a number of other \LaTeX{} packages with similar goals to
% \package{cleveref}, most notably \package{varioref},
% \package{fancyref}, \package{hyperref}'s |\autoref| command, and (for
% theorem-like environments) \package{ntheorem} with the \option{thref}
% option. (There are many others, but these come closest to providing
% similar features to \package{cleveref}.) However, all have certain
% deficiencies which \package{cleveref} attempts to overcome.
%
% The \package{fancyref} package doesn't automatically determine the type
% of thing being referred to. Instead, it relies on you adhering to a
% naming convention for labels. This is usually a good idea in any case,
% but it can occasionally be inconvenient. For example, if you change a
% theorem into a lemma, you have to change the label name, and therefore
% also all cross-references to it. So with \package{fancyref}, you will
% at times be back to searching and replacing label names throughout your
% document. Not to mention missing out on all the other
% \package{cleveref} features, such as automatic sorting and compressing
% of consecutive references, \package{ntheorem} and \package{amsthm}
% support, precise control over hyperlinks, etc.
%
% The enhanced referencing feature provided by the \package{varioref}
% package's\linebreak[4] |\labelformat| command decides how to format
% cross-references when the label is \emph{defined}, rather than when it
% is \emph{referenced}. Often this isn't a problem. But it makes it
% impossible to format cross-references according to the context in which
% they are referenced, which can sometimes be very useful. For example,
% you may want cross-references at the beginning of a sentence formatted
% differently to cross-references in the middle of a sentence. E.g.\ you
% may want to use the abbreviation ``eq.'', but revert to ``Equation'' at
% the beginning of sentences (words at the start of sentences shouldn't
% be abbreviated in English). This is not possible with
% \package{varioref}. Perhaps even more significantly,
% \package{varioref}'s |\labelformat| implementation makes it impossible
% to typeset multiple references automatically; if you want to refer to
% equations |eq1| through |eq3|, with \package{varioref} you are back to
% typing |Eqs.~(\ref{eq1}) to~(\ref{eq3})| by hand. Not to mention
% missing out on all the other \package{cleveref} features. In fact,
% \package{cleveref} fully supports \package{varioref}, taking over
% responsibility for typesetting cross-references, whilst retaining (and
% even enhancing) all the \package{varioref} page-referencing magic.
%
% The \package{hyperref} package's |\autoref| command typesets a name
% before a cross-reference, determined by the cross-reference type. This
% is less flexible than \package{cleveref}'s fully customisable
% cross-reference formatting, but, when combined with \package{varioref},
% the two packages working together come pretty close. But surprisingly,
% even with \package{hyperref}, it is impossible to customise precisely
% which part of the cross-reference is made into a hyperlink in PDF
% documents; this is simple with \package{cleveref}. And it still remains
% impossible to typeset multiple references, have consecutive references
% sorted and compressed automatically, etc.
%
% The \package{ntheorem} package (with the \option{thref} option) does
% the right thing when it comes to how and when the format is
% defined\ldots except that it only works for theorem-like environments.
% It is possible to use it for other environments, but only in a
% bastardized form, by manually supplying an optional argument to every
% |\label| command to specify the label type. \package{Cleveref} works
% equally well with any type of cross-reference, as well as fully
% supporting \package{ntheorem}. And again, \package{cleveref} provides a
% number of additional features over \package{ntheorem}, such as
% multi-references, automatic sorting and compressing of consecutive
% cross-references, control over the placement of hyperlinks, etc.

%
%
% \section{Typesetting Cross-References}
% \label{sec:typesetting}
% \DescribeMacro\cref
% To automatically typeset a cross-reference according to the type of
% thing referred to, simply refer to it using |\cref|\marg{label}.
% \package{Cleveref} imposes just one extra restriction on the names of
% labels: they are no longer allowed to contain commas ``,''. These are
% instead used to typeset multiple cross-references (see below).
%
% \DescribeMacro\Cref
% As it is very difficult\footnote{Actually, very likely impossible!} for
% \LaTeX{} to determine whether a cross-reference appears at the
% beginning of a sentence or not, a beginning-of-sentence variant exists:
% |\Cref|\marg{label}. By default, this typesets the cross-reference with
% the first letter capitalised, and without using an abbreviation in
% those cases where the standard variant does use one. (However, the
% formatting of the |\cref| and |\Cref| forms can be fully and
% independently customised, see \cref{sec:customising}.)
%
% \DescribeMacro\crefrange
% \DescribeMacro\Crefrange
% To typeset a cross-reference range, e.g.\ |Eqs.~(1.1) to~(1.5)|,
% use\linebreak[4] |\crefrange| or |\Crefrange| (depending on the
% capitalisation you require), which take the beginning and end of the
% range as arguments:
% \begin{quote}
%   |\crefrange|\marg{label1}\marg{label2}
% \end{quote}
%
% \DescribeMacro\cref
% \DescribeMacro\Cref
% To typeset multiple cross-references, simply list the labels inside
% the |\cref| or |\Cref| command, separated by commas (recall that you
% are not allowed to use commas in label names when using
% \package{cleveref}):
% \begin{quote}
%   |\cref{|\meta{label1}|,|\meta{label2}|,|\meta{label3}|,|\dots|}|
% \end{quote}
%
% \DescribeMacro{\cref*}
% \DescribeMacro{\Cref*}
% \DescribeMacro{\crefrange*}
% \DescribeMacro{\Crefrange*}
% When \package{cleveref} is used along with the \package{hyperref}
% package (see \cref{sec:customising,sec:other_packages}), additional
% starred variants of all the referencing commands are available. The
% standard referencing commands will make cross-references into
% hyperlinks; the starred variants prevent this, producing the same
% typeset text but without creating hyperlinks.
%
% \DescribeMacro\cpageref
% \DescribeMacro\Cpageref
% To typeset a page reference, use |\cpageref|\marg{label}, which is
% typeset e.g.\ as ``page~3''. At the beginning of a sentence, use
% |\Cpageref| instead. Since page references are always references to,
% well\dots pages, this doesn't gain you so much over |\pageref|. Where
% |\cpageref| comes into its own is in referring to multiple pages:
% \begin{quote}
%   |\cpageref{|\meta{label1}|,|\meta{label2}|,|\meta{label3}|,|\dots|}|
% \end{quote}
% \DescribeMacro\cpagerefrange
% \DescribeMacro\Cpagerefrange
% Predictably enough, |\cpagerefrange| and |\Cpagerefrange| are used to
% typeset references to page ranges:
% \begin{quote}
%   |\cpagerefrange|\marg{label1}\marg{label2}
% \end{quote}
%
% \DescribeMacro\ref
% \DescribeMacro\pageref
% \package{Cleveref} does \emph{not} modify the standard |\ref| or
% |\pageref| commands, so you can still use them to typeset the
% formatted label counter or page number alone, without any additional
% text or formatting.
%
% \DescribeMacro{\namecref}
% \DescribeMacro{\nameCref}
% \DescribeMacro{\lcnamecref}
% \DescribeMacro{\namecrefs}
% \DescribeMacro{\nameCrefs}
% \DescribeMacro{\lcnamecrefs}
% Occasionally, it's useful to produce just the name of a reference,
% without the label itself. For example, if you want to refer to ``this
% section'', but you're not sure whether you might later change the
% section into a chapter, it might be useful to produce just the name
% ``section'' associated with the section's label. If you later change
% the section into a chapter, the text will then automatically change to
% ``this chapter''. The |\namecref| and |\nameCref| do exactly this:
% \begin{quote}
%   |\namecref{sec1}|
% \end{quote}
% is typeset as ``section'' (assuming |sec1| labels a section). The
% |\namecrefs| and |\nameCrefs| commands produce the plural forms. The
% |\lcnamecref| and |\lcnamecrefs| commands force the reference name to
% lowercase, for use when the \option{capitalise} option is enabled (see
% \cref{sec:capitalise}). (When that option is set, |\namecref| produces
% an uppercase reference name.)
%
% There is a slight pitfall that you should be aware of when using the
% |\namecref| commands. They get the reference name from the names
% defined for the label's reference type using |\crefname| or |\Crefname|
% (see \cref{sec:individual_customisation}). The default reference
% formats provide these definitions. However, it is possible to customise
% reference formats using lower-level commands that do not create
% |\crefname| definitions (see \cref{sec:low-level_customisation}). If
% the |\crefname| definitions are missing for a particular reference
% type, |\namecref| and |\nameCref| will produce errors for labels of
% that type. You can fix the error by adding explicit |\crefname|
% definitions for these types.
%
% \DescribeMacro{\labelcref}
% Conversely, it is occasionally convenient to produce just the label
% part of a reference, without the cross-reference name. For example,
% this can be useful when writing in a language in which nouns decline.
% The |\labelcref| command does exactly this, and can also cope with
% multi-references, processing them just as |\cref| does. However, since
% it typesets a multi-reference without any name, \emph{all} labels in a
% |\labelcref| multi-reference \emph{must} be of the same type.
%
% The |\labelcref| command will typeset cross-reference labels using the
% default label format if no type-specific format is defined using
% |\creflabelformat| (see
% \cref{sec:global_customisation,sec:individual_customisation}). Note
% that, if you customise reference formats using the low-level commands,
% you may want to also explicitly define the |\labelcref| formats to
% match, using the |\labelcrefformat| etc.\ commands (see
% \cref{sec:low-level_customisation}).
%
% \DescribeMacro{\labelcpageref}
% Similarly, |\labelcpageref| typesets the page numbers alone, without
% inserting ``page'' in front. Like |\cpageref|, it also handles
% multi-references. Like |\labelcref|, by default |\labelcpageref|
% typesets the page numbers using the default label format, customised
% using |\crefdefaultlabelformat|. If you want to define a separate
% format for |\labelcpageref|, use |\creflabelformat| to customise the
% label format for the ``page'' cross-reference type. (see
% \cref{sec:low-level_customisation}).
%
%
%
% \section{Sorting and Compressing}
% \label{sec:sort&compress}
% When \package{cleveref} typesets lists of multiple cross-references or
% page-references, the default behaviour is to automatically sort the
% list and compress sequences of consecutive cross-references or page
% numbers into a reference range. You can change this behaviour by
% supplying one of the following package options:
% \begin{description}
% \item[\option{sort}] Sort lists of cross-references, but don't compress
%   consecutive references.
% \item[\option{compress}] Compress sequences of consecutive references
%   into a reference range, but don't sort the list of cross-references.
% \item[\option{nosort}] Neither sort lists of cross-references,
%   \emph{nor} compress consecutive references.
% \item[\option{sort\&compress}] Sort lists of cross-references, and
%   compress sequences of consecutive references into a reference
%   range (this is the default).
% \end{description}
%
% Occasionally, you may want to prevent a particular sequence of
% consecutive cross-references from being compressed to a reference
% range, without disabling this feature globally. To achieve this, you
% can separate the cross-references in the list by one or more empty
% references, at the point at which you want to prevent compression. For
% example,
% \begin{quote}
%   |\cref{eq1,eq2,eq3,,eq4}|
% \end{quote}
% will be typeset as
% \begin{quote}
%   eqs.~(1) to~(3) and (4)
% \end{quote}
% or
% \begin{quote}
%   |\cref{eq1,eq2,,eq3,eq4,eq5,,eq6,eq7,eq8}|
% \end{quote}
% will be typeset as
% \begin{quote}
%   eqs.~(1), (2), (3) to~(5) and (6) to~(8)
% \end{quote}
% You can safely put an empty reference between cross-references that
% would never be compressed anyway; it will simply be ignored.
%
% If lists of cross-references are also being sorted (the default), it
% can be a little confusing to work out where the empty reference should
% go in order to prevent compression of a particular consecutive
% sequence. It's best to think of the empty reference as being
% ``attached'' to the cross-reference preceding it. When the list is
% sorted, the empty reference will still appear after the same preceding
% reference, and will prevent it being compressed with any subsequent
% consecutive cross-references. In other words, an empty reference
% ensures that the preceding reference will appear explicitly in the
% final, typeset cross-reference:
% \begin{quote}
%   |\cref{eq3,,eq2,eq1,eq6,eq4,eq5}|
% \end{quote}
% will be typeset as
% \begin{quote}
%   eqs.~(1) to~(3) and (4) to~(6)
% \end{quote}
%
%
%
% \section{Overriding the Cross-Reference Type}
% \label{sec:label_type}
% \DescribeMacro\label
% A label's ``type'' is usually determined by the name of the counter it
% refers to, or in the case of \package{ntheorem} and \package{amsthm}
% theorem-like environments by the environment name. However, sometimes
% it is useful to override the type. \package{Cleveref} provides two
% different mechanisms for accomplishing this.
%
% You can alias a counter to a different cross-reference type using the
% |\crefalias| command:
% \begin{quote}
%   |\crefalias|\marg{counter}\marg{type}
% \end{quote}
% \meta{counter} will then use the cross-reference formatting of
% \meta{type}. This can be useful if you want multiple counters to use
% the same cross-reference format.
%
% Occasionally, you may want to override the cross-reference type for one
% particular label, one-off. You can do this by supplying the desired
% type as an optional argument to the |\label| command:
% \begin{quote}
%   |\label|\oarg{type}\marg{label}
% \end{quote}
%
% One circumstance in which is useful is when you want to define a
% special cross-reference format for certain labels of a given type. By
% supplying a type that doesn't already exist as the optional argument to
% |\label|, you can then define the cross-reference format for that new
% type in whatever way you like, without affecting other cross-references
% of the same type. For example, if a particular equation contains
% multiple expressions and you want it to always be referred to in the
% plural, you could use:
% \begin{quote}
%   |\crefname{pluralequation}{eqs.}{eqs.}|\\
%   \dots\\
%   |\label[pluralequation]{eq1}|
% \end{quote}
% You can of course reuse this format for other plural equations, too.
%
% If you need to do this frequently, it can become tedious specifying the
% label explicitly each time. An alternative is to use the
% \package{aliascnt} package. This lets you define one counter to be an
% alias for another, so that effectively the same counter has two names.
% Since \package{cleveref} determines the label type from the counter
% name, the two counter aliases can have different cross-reference
% formats whilst really being the same counter. You have to somehow
% arrange for the correct counter alias to be used depending on which
% cross-reference format you want (probably by defining two variants of
% the environment in question). But the effort involved might be worth
% the convenience of not having to remember to pass an explicit optional
% argument to a large number of labels.
%
% You can use this trick to get different cross-reference formats for
% different theorem-like environments,\footnote{This trick seems to
% belong to \LaTeX{} mythology, and certainly isn't my own idea! But I
% haven't been able to definitively track down who originally came up
% with it.} \emph{without} using the \package{amsthm} or
% \package{ntheorem} package (although using one of those packages is a
% better solution if available). For example,
% \begin{quote}
%   |\usepackage{aliascnt}|\\
%   |\usepackage{cleveref}|\\
%   |\newaliascnt{lemma}{theorem}|\\
%   |\newtheorem{lemma}[lemma]{Lemma}|\\
%   |\aliascntresetthe{lemma}|\\
%   |\crefname{lemma}{lemma}{lemmas}|
% \end{quote}
% Note that \package{aliascnt} must be loaded before \package{cleveref},
% and any \cmd{\newaliascnt} commands \emph{must} come \emph{after}
% \package{cleveref} has been loaded.
%
%
%
% \section{Options that Modify the Cross-Reference Format}
%
% \subsection{Capitalising All Cross-Reference Names}
% \label{sec:capitalise}
% \DescribeMacro{capitalise}
% Many authors prefer to always capitalise cross-reference names,
% regardless of where they appear in the sentence, writing Theorem~1 and
% Equation~3 (as opposed to theorem~1 and equation~3). If you count
% yourself among this group, you can pass the \option{capitalise} option
% to the \package{cleveref} package (\option{capitalize} also works).
%
% All the default cross-reference formats will then have the first letter
% capitalised, as will the automatically generated |\cref| variants (see
% \cref{sec:individual_customisation,sec:low-level_customisation}).
% (However, if you explicitly define a |\cref| variant to \emph{not} be
% capitalised, \package{cleveref} will still honour your definition. In
% other words, you're responsible for defining the capitalisation
% correctly in your own format definitions.)
%
% You should \emph{still} use the |\Cref| variants at the beginning of
% sentences, for one thing, because abbreviations should not be used at
% the beginning of a sentence,\footnote{At least in English; I'm not sure
% about other languages.} and for another, in case you later change your
% mind and remove the \option{capitalise} option.
%
%
% \subsection{Including Names in Hyperlink Targets}
% \label{sec:nameinlink}
% \DescribeMacro{nameinlink}
% When using the \package{hyperref} package, \package{cleveref}
% automatically makes all cross-references into hyperlinks to the
% corresponding reference. By default, only the label itself forms part
% of the hyperlink target (i.e.\ the text you can click on to navigate to
% the cross-reference). The cross-reference name is not part of the
% hyperlink. By contrast, \package{hyperref}'s |\autoref| command
% \emph{does} includes the name as part of the hyperlink. If you prefer
% to include the names in the hyperlinks when using \package{cleveref},
% you can pass the \option{nameinlink} option to the \package{cleveref}
% package. (For even more control over the placement of the hyperlink
% target, use the commands for customising the cross-reference format.
% See \cref{sec:customising}.)
%
% However, use of this option is discouraged on stylistic grounds.
% Firstly, when producing PDF output \package{hyperref} by default
% surrounds hyperlinks with red boxes, which looks particularly ugly when
% the entire cross-reference name is surrounded by a red box (though this
% unfortunate default can be changed using \package{hyperref} package
% options; see the \package{hyperref} documentation for details).
% Secondly, and more significantly, when using multi-references only the
% first reference in a group can include the cross-reference name as part
% of its hyperlink target, for obvious reasons. The hyperlink targets for
% the other references in the group will necessarily be just the labels.
% This makes for somewhat non-uniform typesetting of hyperlinks, with the
% first cross-reference in a multi-reference having a much larger
% hyperlink target than the others.
%
%
% \subsection{Abbreviations in Cross-Reference Names}
% \label{sec:noabbrev}
% \DescribeMacro{noabbrev}
% The default cross-reference names for some languages use common
% abbreviations for some of the names (e.g.\ in the default English
% format, |\cref{eq1}| will be typeset as |eq.~(1)|). Some authors may
% prefer to always use the full name, rather than an abbreviation
% (|equation~(1)| instead of |eq.~(1)|). To disable all use of
% abbreviations in the default cross-reference names, pass the
% \option{noabbrev} option to the \package{cleveref} package.
%
% Note that the default names \emph{never} use abbreviations for the
% start-of-sentence variants (|\Cref| etc.)
% This is because in good written English (and likely other languages
% too), abbreviations should never be used at the beginning of a
% sentence. Many of \TeX{}'s default settings (e.g.\ page margins) are
% specifically chosen to encourage good typesetting style.
% \package{Cleveref} tried to follow the same philosophy. If despite this
% you insist on using abbreviations at the start of sentences, you will
% need to customise the start-of-sentence formats yourself.
%
%
%
%
% \section{Customising the Cross-Reference Formats}
% \label{sec:customising}
% The \package{cleveref} package allows you to take full control of the
% typesetting of cross-references, by allowing the formatting to be
% customised. Defaults appropriate for English documents are provided for
% the standard label types,\footnote{For any pedantic classics scholars
% out there: ``lemmas'' is recognised as a valid plural form of ``lemma''
% in all current versions of the Oxford English Dictionary. ``Lemmata''
% was last heard in a mathematical debate that took place in a pub just
% around the corner from Hadrian's wall\dots a few years before the
% Romans pulled out of Britain. \package{Cleveref} might have ``clever''
% in its name, but even that doesn't make it pretentious enough to use
% ``lemmata'' for the plural of ``lemma''.} and support for a number of
% languages is provided via package options (see
% \cref{sec:language_babel}). But if you don't like the defaults, or are
% writing in a language that is not supported yet,\footnote{Any
% contributions of translations for missing languages are very welcome!
% See \cref{sec:new-features} for information on how to contribute
% translations.} or you need to refer to something for which no default
% format is defined, then you can take charge and define your own
% formats.
%
% If \package{cleveref} encounters a cross-reference to a type it does
% not know, it will produce a ``reference type undefined'' warning, and
% typeset the cross-reference as
% \begin{quote}
%   {\bf ??}~|\ref|\marg{label}
% \end{quote}
% i.e.\ the label counter preceded by a double question mark. The error
% message indicates the name of the unknown cross-reference type, which
% you will then probably want to define. (References to undefined labels
% still produce a ``reference undefined'' warning and appear as a double
% question mark, as usual.)
%
% The cross-reference formats are usually constructed out of components:
% the cross-reference name (different for each type of cross-reference),
% the format for the label itself, and the conjunctions used in reference
% ranges and lists of multiple cross-references. There are two levels of
% customisation: you can either customise the components, or you can take
% full control and override the component-derived format entirely.
%
% \package{Cleveref} treats page references, as produced e.g.\ by
% |\cpageref|, as cross-references with the type ``page''. Therefore, all
% of the mechanisms for customising cross-references apply equally well
% to page references, simply by using ``page'' as the cross-reference
% type.
%
%
% \subsection{Customising the Cross-Reference Components}
% \label{sec:component_customisation}
%
% \subsubsection{Global Customisation}
% \label{sec:global_customisation}
% The global customisation commands affect all cross-reference formats,
% unless they are overridden by lower-level customisation commands.
%
% \DescribeMacro\crefdefaultlabelformat
% The format for the label counter itself can be customised globally
% using
% \begin{quote}
%   |\crefdefaultlabelformat|\marg{format}
% \end{quote}
% The \meta{format} argument can be any valid \LaTeX{} code, though you
% will need to |\protect| fragile commands. It can (and almost certainly
% should!) contain three arguments, |#1|, |#2| and |#3|. The first
% argument is the formatted version of the label counter (e.g.\
% |\thesection|). The other two are used to mark the beginning and end
% of the part of the cross-reference that should form the hyperlink when
% the \package{hyperref} package is used (see
% \cref{sec:other_packages}). For example, if you wanted to surround all
% labels with square brackets, without the square brackets themselves
% being part of the hyperlink, you would need:
% \begin{quote}
%   |\crefdefaultlabelformat{[#2#1#3]}|
% \end{quote}
% The hyperlink arguments |#2| and |#3| \emph{must} appear in that
% order. (Leaving them out completely will not cause an error, but in
% that case no hyperlink will be created when \package{hyperref} is
% used, and there are better ways to achieve this. See
% \cref{sec:typesetting,sec:other_packages}.)
%
% Note that the default format for equation cross-references already
% overrides |\crefdefaultlabelformat| in order to surround the label with
% parentheses, so the redefining |\crefdefaultlabelformat| will have no
% effect on equations. The label format for equations must be customised
% separately if you want to change it (see
% \cref{sec:individual_customisation}).
%
% \DescribeMacro\crefrangeconjunction
% The conjunction used in a reference range can be customised by
% defining |\crefrangeconjunction|:
% \begin{quote}
%   |\newcommand{\crefrangeconjunction}|\marg{conjunction}
% \end{quote}
% It does not have to be an actual conjunction in the linguistic sense,
% e.g.\ it is perfectly reasonable to define it to be an endash
% ``|--|''. |\crefrangeconjunction| is used directly between the start
% and end references in a reference range, without any additional space
% surrounding it, e.g.\ |\crefrange{thm1}{thm2}| is typeset as
% \begin{quote}
%   |theorems~\ref{thm1}\crefrangeconjunction\ref{thm2}|
% \end{quote}
% so you may or may not want to include surrounding space, depending on
% the formatting you desire. For example,
% \begin{quote}
%   |\newcommand{\crefrangeconjunction}{ and~}|
% \end{quote}
% does require surrounding space, whereas
% \begin{quote}
%   |\newcommand{\crefrangeconjunction}{--}|

% does not.
%
% \DescribeMacro\crefrangepreconjunction
% \DescribeMacro\crefrangepostconjunction
% There are two other ``conjunction'' commands available for customizing
% the formatting for reference ranges. These are
% |\crefrangepreconjunction| and |\crefrangepostconjunction|, which
% insert text before the first label defining the range, and after the
% second label, respectively. For example, when these commands are
% defined, |\crefrange{thm1}{thm2}| is typeset as
% \begin{quote}
%   |theorems~\crefrangepreconjunction\ref{thm1}|\\
%   | |\ding{229} |\crefrangeconjunction\ref{thm2}\crefrangepostconjunction|
% \end{quote}
% These commands are not used in the default English format definitions,
% but they are needed in some languages to correctly express a range. For
% example, the Italian format defines |\crefrangepreconjunction| to be
% ``da'', so that |\crefrange{thm1}{thm2}| produces
% \begin{quote}
%   |teorema da~\ref{thm1} a~\ref{thm2}|
% \end{quote}
%
% \DescribeMacro\crefpairconjunction
% \DescribeMacro\crefmiddleconjunction
% \DescribeMacro\creflastconjunction
% The conjunctions used in lists of multiple cross-references can be
% customised by defining the commands |\crefpairconjunction|,
% |\crefmiddleconjunction| and |\creflastconjunction|:
% \begin{quote}
%   |\newcommand{\crefpairconjunction}|\marg{conjunction}\\
%   |\newcommand{\crefmiddleconjunction}|\marg{conjunction}\\
%   |\newcommand{\creflastconjunction}|\marg{conjunction}
% \end{quote}
% |\crefpairconjunction| is used when there are only two cross-references
% in the list, |\creflastconjunction| is used between the penultimate and
% final cross-reference in a list of more than two, and
% |\crefmiddleconjunction| is used between all the others. Again, they do
% not have to be conjunctions in the linguistic sense, and the same
% considerations about surrounding space apply as in the case of
% |\crefrangeconjunction|. For example, the default definition of
% |\crefmiddleconjunction| is:
% \begin{quote}
%   |\newcommand{\crefmiddleconjunction}{, }|
% \end{quote}
%
% \DescribeMacro\crefpairgroupconjunction
% \DescribeMacro\crefmiddlegroupconjunction
% \DescribeMacro\creflastgroupconjunction
% By default, the conjunctions used to separate sub-lists of different
% cross-reference types in a multi-reference are identical to those used
% to separate cross-references of the same type.\footnote{More
%   accurately, if you redefine $\backslash$crefpairconjunction etc.\ in
%   your preamble, $\backslash$crefpairgroupconjunction etc.\ are
%   automatically redefined so that they match. (In some languages, the
%   default definition of $\backslash$creflastgroupconjunction has an
%   additional comma lacking in $\backslash$creflastconjunction.)} You
% can override this by defining the conjunction commands
% |\crefpairgroupconjunction|, |\crefmiddlegroupconjunction| and
% |\creflastgroupconjunction|.
%
% For example,
% \begin{quote}
%   |\cref{eq1,eq2,eq3,thm1,thm2,fig1,thm3}|
% \end{quote}
% is typeset as
% \begin{quote}
%   eqs.~(1)|\crefrangeconjunction|(3)|\crefmiddlegroupconjunction|%\\
%   theorems~1|\crefpairconjunction|2|\crefmiddlegroupconjunction|%\\
%   fig.~1|\creflastgroupconjunction{}|theorem~3
% \end{quote}

%
% \subsubsection{Customising Individual Cross-Reference Types}
% \label{sec:individual_customisation}
% \DescribeMacro\crefname
% \DescribeMacro\Crefname
% The cross-reference name for a given cross-reference type is customised
% using the |\crefname| and |\Crefname| commands:
% \begin{quote}
%   |\crefname|\marg{type}\marg{singular}\marg{plural}\\
%   |\Crefname|\marg{type}\marg{singular}\marg{plural}
% \end{quote}
% used by the |\cref| and |\Cref| commands, respectively. You must supply
% both \meta{singular} and \meta{plural} forms of the name. If the
% corresponding |\Crefname| is undefined when |\crefname| is called, it
% will automatically define |\Crefname| to be a capitalised version of
% |\crefname|, using |\MakeUppercase|. Conversely, if the corresponding
% |\crefname| is undefined when |\Crefname| is called, it will
% automatically define |\crefname| to be a lower-case version of
% |\Crefname|, using |\MakeLowercase|. Obviously, this will only work
% properly if the names begin with a letter. If the first letter is a
% special character construct, such as an accented character, you will
% need to surround it by braces. If the first thing in the name is
% \emph{not} a letter at all (e.g.\ if it is a \LaTeX{} command), you
% \emph{must} define both capitalisation variants explicitly. Otherwise
% you will get strange and fatal errors when processing the document.
%
% The cross-reference \meta{type} is usually the name of the counter for
% the environment (equation, chapter, section, etc.). The exceptions are
% appendices, labels whose type has been overridden explicitly by
% supplying an optional argument (see \cref{sec:label_type}), and
% theorem-like environments when the \package{ntheorem} of
% \package{amsthm} packages are loaded, for which \meta{type} should
% instead be the environment name (lemma, corollary, definition, etc.)
% even when different environments are part of the same numbering
% sequence. (\package{ntheorem} and \package{amsthm} provide extra
% information about the environment when different theorem-like
% environments share a common counter, which \package{cleveref} makes use
% of to distinguish between them automatically.) In the case of
% appendices, the \meta{type} is ``appendix'' for the top-level
% sectioning command (|\chapter| or |\section|, depending on the document
% class), ``subappendix'' for the sectioning command one level below
% (|\section| or |\subsection|), ``subsubappendix'' for the next level of
% sectioning command, etc.
%
% For convenience, if they have not been otherwise customised by the end
% of the preamble, the cross-reference name (and label format) for
% |subsection| is by default inherited from that of |section|, and that
% of |subsubsection| is inherited from |subsection| (which might itself
% have been inherited from |section|). Similarly for |subappendix|,
% |subsubappendix| and |subsubsubappendix|, and also for |enumii|,
% |enumiii|, |enumiv| and |enumv|, which inherit from |enumi|. Finally,
% |subfigure| and |subtable| inherit from |figure| and |table|,
% respectively.
%
% \DescribeMacro\creflabelformat
% You may want the label format for a particular cross-reference type to
% differ from the global format set by |\crefdefaultlabelformat| (see
% \cref{sec:global_customisation}). You can do this using
% \begin{quote}
%   |\creflabelformat|\marg{type}\marg{format}
% \end{quote}
% The \meta{type} argument is the cross-reference type to customise, and
% the \meta{format} argument defines the label format for
% cross-references of that type. As in the case of\linebreak[4]
% |\crefdefaultlabelformat|, the latter should contain the three
% arguments |#1|, |#2| and |#3|, the first being the formatted version of
% the label counter, the others determining the beginning and end of the
% portion that becomes a hyperlink when the \package{hyperref} package
% is loaded (see \cref{sec:other_packages}). |#2| and |#3| \emph{must}
% appear in that order.
%
% \DescribeMacro\crefrangelabelformat
% Normally, the start and end references in a reference range are
% typeset using the usual label format (as defined by
% |\crefdefaultlabelformat| or |\creflabelformat|) separated by
% |\crefrangeconjunction| (\cref{sec:global_customisation}). You can
% override this for a given cross-reference type using
% \begin{quote}
%   |\crefrangelabelformat|\marg{type}\marg{format}
% \end{quote}
% The \meta{format} argument should contain six arguments: |#1|, |#2|,
% |#3|, |#4|, |#5|, |#6|. The first two (|#1| and |#2|) are the formatted
% versions of the two label counters defining the reference range. The
% next two (|#3| and |#4|) denote the beginning and end of the hyperlink
% for the first reference, the final two (|#5| and |#6|) the hyperlink
% for the second reference. The hyperlink arguments \emph{must} appear
% in order. For example,
% \begin{quote}
%   |\crefrangelabelformat{equation}{(#3#1#4) to~(#5#2#6)}|
% \end{quote}
%
%
% \subsubsection{Automatic \textbackslash\texttt{newtheorem} Definitions}
% \DescribeMacro\newtheorem
% The standard \LaTeX{} |\newtheorem| command for defining new
% theorem-like environments provides enough information to deduce a
% reasonable cross-reference name for the new environment. So
% \package{cleveref} automatically defines an appropriate cross-reference
% name for new theorem-like environments. This automatic definition is
% only used if no default definition is provided by \package{cleveref}
% itself, and if no |\crefname| or |\Crefname| definition is given
% explicitly (see \cref{sec:individual_customisation}).
%
% The caveat with this automatic definition is that, although
% |\newtheorem| essentially provides the singular form of the
% cross-reference name, it doesn't provide the plural form. And there is
% no reliable way of constructing the plural form from the
% singular.\footnote{If you're a native English-speaker, you might think
% that just adding an `s' would work, though a moment's thought will
% provide examples of words where this will fail. If you're a non-English
% speaker, it probably won't even occur to you to claim that plurals can
% reliably be constructed automatically!} Therefore, if the plural form
% is ever required, \package{cleveref} will produce a ``reference type
% undefined'' warning, and typeset the cross-reference where the plural
% form is required as:
% \begin{quote}
%   {\bf ??}~|\ref|\marg{label} \dots
% \end{quote}
% In this case, you will have to provide an explicit |\crefname| or
% |\Crefname| definition yourself, to define the plural form as well as
% the singular form.
%
% Note that this has \emph{nothing whatsoever} to do with automatically
% determining the type of theorem-like environment in a cross-reference!
% For that, you need to load either the \package{ntheorem} or the
% \package{amsthm} package. See \cref{sec:non-bugs} for more details.
%
%
%
% \subsection{Low-Level Customisation: Taking Full Control}
% \label{sec:low-level_customisation}
% If you need more precise control over the cross-reference format than
% is possible by customising the individual components, then you can take
% full control of the format for any given type, overriding the
% component-derived format entirely. The formats for single
% cross-references, reference ranges and multi-references are customised
% separately. If you only customise some of these, the other formats will
% be constructed from components, as usual.
%
% Note that when deciding which cross-references should be grouped
% together for sorting and/or compressing, \package{cleveref} does
% something slightly more complicated than simply checking whether the
% reference types match. In fact, it checks whether the reference
% \emph{formats} match.\footnote{To be precise, \package{cleveref} checks
% whether the $\backslash$|crefformat| definitions match.} This will
% always be the case for cross-references of the same type. But it could
% also be the case for cross-references that have different types, if the
% cross-reference formats happen to be identical.
%
% The reason for doing this is to allow cross-references to e.g.\
% sections and subsections to be grouped together if they have identical
% formats. The default formats for the sectioning commands, figures and
% subfigures, tables and subtables, and enumerated lists are set up in
% this way. If you change any of them using the low-level customisation
% commands, but still want them to be grouped together, then you must
% ensure that the formats are \emph{identical}. (It is \emph{not}
% sufficient for the formats to produce identical typeset text; the
% format definitions must contain identical \LaTeX{} code.)
%
% Note that if you use the low-level customisation commands, you might
% still want to provide |\crefname| and |\Crefname| definitions too, so
% that the |\namecref| commands will work (see \cref{sec:typesetting}).
%
%
% \subsubsection{Single Cross-References}
% \label{sec:ref_format}
% \DescribeMacro\crefformat
% \DescribeMacro\Crefformat
% Cross-reference formats for \emph{single} cross-references are defined
% or redefined using the |\crefformat| and |\Crefformat| commands, which
% are used by the |\cref| and |\Cref| commands respectively. These take
% two arguments: the cross-reference type, and the formatting code:
% \begin{quote}
%   |\crefformat|\marg{type}\marg{format}\\
%   |\Crefformat|\marg{type}\marg{format}
% \end{quote}
% The \meta{type} is usually the name of the counter, except for labels
% whose type has been overridden explicitly (see \cref{sec:label_type}),
% theorem-like environments \emph{when the \package{ntheorem} or
% \package{amsthm} package is loaded}, in which case it is the
% environment name, and appendices. For the latter, the \meta{type} is
% ``appendix'' for the top-level sectioning command (|\chapter| or
% |\section|, depending on the document class), ``subappendix'' for the
% sectioning command one level below (|\section| or |subsection|),
% ``subsubappendix'' for the next level of sectioning command, etc.
%
% As in the case of the |\crefname| and |\Crefname| commands, if the
% corresponding |\Crefformat| is undefined when |\crefformat| is called,
% it will define the |\Crefformat| to produce a capitalised version of
% |\crefformat|, using |\MakeUppercase|. Conversely, if the corresponding
% |\crefformat| is undefined when |\Crefformat| is called, it will define
% the |\crefformat| to produce a lower-case version of |\Crefformat|,
% using |\MakeLowercase|. Obviously, this will only work properly if the
% format starts with a letter, and letter constructs (such as accented
% letter constructs) must be surrounded by braces (see
% \cref{sec:global_customisation}).
%
% The \meta{format} argument can be any valid \LaTeX{} code, though you
% will need to |\protect| fragile commands. It should contain three
% arguments, |#1|, |#2| and |#3|. The first argument is the formatted
% version of the label counter (e.g.\ |\theequation|). The other two are
% used to mark the beginning and end of the part of the cross-reference
% that forms the hyperlink when the \package{hyperref} package is used,
% and \emph{must} appear in that order (see \cref{sec:other_packages}).
%
% As an example,
% \begin{quote}
%   |\crefformat{equation}{Eq.~(#2#1#3)}|
% \end{quote}
% will typeset equation references as
% \begin{quote}
%   Eq.~(\meta{counter})
% \end{quote}
% with the counter (excluding the parentheses) forming the hyperlink.
%
% Note that the hyperlink arguments are \emph{not} letters, so if |#2|
% appears at the beginning of \meta{format}, \package{cleveref} will not
% be able to automatically define the other capitalisation variant
% automatically using |\MakeUppercase| or |\MakeLowercase|. In this case,
% you will have to define both variants separately. For example, if you
% wanted the ``Eq.''\ to be part of the hyperlink, you would have to
% explicitly define:
% \begin{quote}
%   |\crefformat{equation}{#2eq.~(#1)#3}|\\
%   |\Crefformat{equation}{#2Eq.~(#1)#3}|
% \end{quote}
%
%
% \subsubsection{Reference Ranges}
% \label{sec:ref_range_format}
% \DescribeMacro\crefrangeformat
% \DescribeMacro\Crefrangeformat
% The format for reference ranges is defined by |\crefrangeformat|
% and\linebreak[4] |\Crefrangeformat|. Like |\creformat| and
% |\Crefformat|, the commands take two arguments: the cross-reference
% type, and the formatting code.
% \begin{quote}
%   |\crefrangeformat|\marg{type}\marg{format}\\
%   |\Crefrangeformat|\marg{type}\marg{format}
% \end{quote}
% The same comments apply as in the case of single cross-references: the
% \meta{type} is usually the name of the counter, except for appendices,
% labels with explicitly overridden types, and theorem-like environments
% when \package{ntheorem} or \package{amsthm} are loaded. Again, if the
% other-capitalisation variant is not already defined, it will be defined
% automatically.
%
% The \meta{format} argument can again be any valid \LaTeX{} code, with
% fragile commands |\protect|ed. However, this time it should contain
% \emph{six} arguments, |#1|--|#6|. The first two (|#1| and |#2|) are the
% formatted versions of the label counters, the next two (|#3| and |#4|)
% are used to mark the beginning and end of the hyperlink for the first
% cross-reference, and the final two (|#5| and |#6|) mark the beginning
% and end of the second cross-reference's hyperlink.
%
% As an example,
% \begin{quote}
%   |\crefrangeformat{equation}{eqs.~(#3#1#4) to~(#5#2#6)}|
% \end{quote}
% would typeset equation reference ranges as
% \begin{quote}
%   eqs.~(\meta{counter1}) to~(\meta{counter2})
% \end{quote}
% with the counters (excluding the parentheses) forming the hyperlinks.
%
%
% \subsubsection{Multiple Cross-References}
% \label{sec:multiple_ref_format}
% \DescribeMacro\crefmultiformat
% \DescribeMacro\Crefmultiformat
% \DescribeMacro\crefrangemultiformat
% \DescribeMacro\Crefrangemultiformat
% The format for multiple cross-references is defined by
% |\crefmultiformat| and\linebreak[4] |\Crefmultiformat|, and that of
% reference ranges within multiple cross-references by
% |\crefrangemultiformat| and |\Crefrangemultiformat|. Multi-references
% also require \emph{all} the other cross-reference formats to be defined
% (see \cref{sec:ref_format,sec:ref_range_format}), including the single
% reference range formats, even if you never use the |\crefrange| and
% |\Crefrange| commands.
%
% The commands all take five arguments: the cross-reference type, the
% format for the first cross-reference in a list, the format for the
% second cross-reference in a list of two, the format for the middle
% cross-references in a list of more than two, and the format for the
% last cross-reference in a list of more than two.
% \begin{quote}
%   |\crefmultiformat|\marg{type}\marg{first}\marg{second}\marg{middle}\marg{last}\\
%   |\Crefmultiformat|\marg{type}\marg{first}\marg{second}\marg{middle}\marg{last}\\
%   |\crefrangemultiformat|\marg{type}\marg{first}\marg{second}\marg{middle}\marg{last}\\
%   |\Crefrangemultiformat|\marg{type}\marg{first}\marg{second}\marg{middle}\marg{last}
% \end{quote}
%
% The \meta{type} is, as ever, the counter name (except for appendices,
% explicitly overridden label types, and theorem-like environments when
% the \package{ntheorem} or \package{amsthm} packages are loaded). The
% same considerations apply to the formatting arguments \meta{first},
% \meta{second}, \meta{middle} and \meta{last} as for the \meta{format}
% argument of |\crefformat| or |\crefrangeformat|, including the meaning
% of the arguments that should appear in the formatting code (|#1|, |#2|
% and |#3| for |\crefmultiformat| and |\Crefmultiformat|, |#1|--|#6| for
% |\crefrangemultiformat| and |\Crefrangemultiformat|). However, when the
% corresponding other-capitalisation variant is automatically defined,
% only the first letter of the \meta{first} argument is upper- or
% lower-cased; the other arguments are defined to be identical for both
% variants.
%
% Be careful to get the spaces at the beginning and end of the formatting
% code correct: the \meta{first} and \meta{second}, or \meta{first},
% \meta{middle} and \meta{last}, \LaTeX{} code snippets are typeset one
% after another in a multi-reference, with no space separating them. You
% may or may not want spaces at the beginning or end of the formatting
% code, depending on the formatting you desire. For example, in the
% default equation format:
% \begin{quote}
%   |\crefmultiformat{equation}{eqs.~(#2#1#3)}%|\\
%   |  { and~(#2#1#3)}{, (#2#1#3)}{ and~(#2#1#3)}|
% \end{quote}
% the \meta{middle} argument should \emph{not} have a space at the
% beginning, whereas the \meta{second} and \meta{last} arguments
% \emph{should} have a space.
%
%
% \subsubsection{Label Cross-References}
% If you define the format for a particular cross-reference type using
% the low-level customisation commands, and still want to use the
% |\labelcref| command to produce just the label part of the
% cross-reference, then you must also define the appropriate |\labelcref|
% formats for that type. This is done using the |\labelcrefformat|,
% |\labelcrefrangeformat|, |\labelcrefmultiformat| and
% |\labelcrefrangemultiformat| commands. Their syntax is identical to
% that of the corresponding |\crefformat|, |\crefrangmeformat|,
% |\crefmultiformat| or |\crefrangemultiformat| command. Typically, the
% |\labelcref| formats should be defined identically to the standard
% |\cref| formats, except for the \meta{first} part, which should leave
% off the cross-reference name. This is not enforced, however.
%
%
%
% \section{Advanced Cross-Reference Formating}
% When you define a custom cross-reference format using
% |\creflabelformat|, |\creformat| et al.\ (see \cref{sec:customising}),
% you're not merely defining a pattern with placeholders to be filled in.
% You're really defining the body of a LaTeX macro, with the formatted
% labels as arguments. This is a very powerful tool. It means that the
% only limit on how you can process the labels is your ability to code it
% in \TeX{}!\footnote{And since \TeX{} is Turing-complete, that means you
% can do anything you like short of solving the Halting Problem.} Which
% potentially allows for very sophisticated cross-reference formatting.
%
% One example of this is removing common prefixes from reference ranges.
% E.g.\ if you're numbering equations within sections, and |eq1|, |eq2|
% and |eq3| are all in the section 1.2, then you might want to typeset
% |\cref{eq1,eq2,eq3}| as ``eqs.~(1.2.1--3)'' instead of ``eqs.~(1.2.1)
% to~(1.2.3)''. Similarly, if |eq1a|, |eq1b| and |eq1c| are
% \package{amsmath} subequations, you might want to typeset
% |\cref{eq1a,eq1b,eq1c}| as ``eqs.~(1a--c)'' instead of ``eqs.~(1a)
% to~(1c)''.
%
% \package{Cleveref} provides a useful utility macro for this:
% |\crefstripprefix|, which takes two strings as arguments, and returns
% the second one with any common prefix stripped off. (However, the very
% last run of digits or letters in the string is retained in its
% entirety, even if it has a part in common.) With the help of this
% macro, you can produce the desired reference-range formatting with:
% \begin{quote}
%   |\crefrangelabelformat{equation}|\\
%   | |\ding{229} |{(#3#1#4--#5\crefstripprefix{#1}{#2}#6)}|\\
%   |\crefrangelabelformat{subequation}|\\
%   | |\ding{229} |{(#3#1#4--#5\crefstripprefix{#1}{#2}#6)}|
% \end{quote}
%
%
%
% \section{Language, \package{babel} and \package{polyglossia}
%             support}
% \label{sec:language_babel}
% \package{Cleveref} supports different languages via package options, in
% the usual way, though not all languages are supported
% yet.\footnote{Contributions of translations for missing languages are
% very welcome! See \cref{sec:new-features} for information on how to
% contribute translations.} Basic \package{cleveref} language support
% will work even if \package{babel} or \package{polyglossia} are not
% loaded. The only exception currently is Catalan (which requires the
% |\lgem| command provided by these packages).
%
% The \package{babel} package is fully supported if it is loaded,
% allowing you to change the language used in cross-references using the
% \package{babel} language switching commands, such as |\selectlanguage|
% and |\foreignlanguage|. Similar support is provided for the
% \package{polyglossia} babel replacement package.
%
% Note that when using \package{babel}, you still need to tell
% \package{cleveref} which language it should use for the default
% cross-reference formats. It is \emph{not} sufficient to pass the
% language option to \package{babel} alone. You \emph{must} also
% \emph{either} pass the language options to \package{cleveref} package
% directly when loading it:
% \begin{quote}
%   |\usepackage|\oarg{language}|{cleveref}|
% \end{quote}
% \emph{or} specify the desired language globally as a document class
% option:
% \begin{quote}
%   |\documentclass|\oarg{language}\marg{class}\\
%   |\usepackage{babel}|\\
%   |\usepackage{cleveref}|\\
% \end{quote}
% The latter method is strongly recommended. \LaTeX{} automatically
% passes document class options to \emph{every} loaded package. So
% specifying the language as a global option causes the appropriate
% language support to be enabled automatically in every package that
% supports it.
%
% When writing multi-language documents, you may need to specify multiple
% language options in order to load \package{babel} support for all of
% them. In this case, \package{babel} sets the initial document language
% to the \emph{last} language option. (See the \package{babel}
% documentation for more details.) \package{Cleveref} does the same: the
% last language in the option list determines the language for the
% initial cross-reference format definitions; additional language options
% load \package{cleveref} support for switching between those languages.
%
% \package{Polyglossia} uses a different mechanism for selecting and
% loading languages, and ignores package language options entirely. The
% default language must be set using \cmd{\setdefaultlanguage}, and
% additional languages are loaded using \cmd{\setotherlanguage}.
% \package{Cleveref} recognises these commands, so you should \emph{not}
% pass language options to \package{cleveref} when using
% \package{polyglossia}. (Passing language options to \package{cleveref},
% either as package options or global options, will override the default
% language set by \package{polyglossia}'s \cmd{\setdefaultlanguage}.)
% Note that the |\setdefaultlanguage| option \emph{must} come before
% \package{cleveref} is loaded, so that \package{cleveref} knows what
% default language you want. (If you don't do this, \package{cleveref}
% will generate a warning message in the log.)
%
% The \package{babel} and \package{polyglossia} support works by
% redefining the cross-reference names and conjunctions for the default
% cross-reference types. Any customisations you make to the default
% cross-reference names and conjunctions \emph{in the preamble} apply to
% the main language (i.e.\ the last language listed in the options). A
% |\selectlanguage| \package{babel} command (or similar) in the document
% body will override these customisations, replacing them with the
% defaults for the newly selected language. If you later use
% |\selectlanguage| to switch back to the main language, any
% customisations from the preamble will be restored. If you want to
% customise cross-reference names or conjunctions for any language other
% than the main one, you either have to explicitly redefine them after
% every language switching command, or hook the redefinitions into
% \package{babel} or \package{polyglossia}'s language switching
% mechanism. (See section ``Language and \package{babel} Support'' in the
% full implementation documentation, and the \package{babel} or
% \package{polyglossia} package documentation.)
%
% If you have defined formats for new cross-reference types for which no
% defaults are provided, then you're on your own. \package{Cleveref} will
% not know how to redefine them for other languages, and again you will
% have to take care of it yourself, either by explicitly redefining them
% in your document after each language switch, or by hooking the
% redefinitions into \package{babel} or \package{polyglossia}'s language
% switching mechanisms.
%
% On the other hand, since the language switching commands only modify
% the cross-reference components, if you use the low-level customisation
% commands to take full control of the format for a particular
% cross-reference type, then (unless you're careful) you take it out of
% the control of \package{babel} or \package{polyglossia} entirely. If
% you want to use the low-level customisation commands, but \emph{do}
% still want the language switching commands to work, then you have to
% use the component macros in your customised formats. The
% cross-reference names are stored in macros called
% |\cref@|\meta{type}|@name|, |\Cref@|\meta{type}|@name|,
% |\cref@|\meta{type}|@name@plural|, and
% |\Cref@|\meta{type}|@name@plural|. (Note that since these
% macro names contain the ``@'' character, you must use |\makeatletter|
% and |\makeatother| to access them.)
%
% For example, if you wanted to redefine the equation format so that the
% cross-reference name (``equation'') was also part of the
% hyperlink,\footnote{This is merely as an example. Including names in
% hyperlinks is more easily accomplished by setting the
% \option{nameinlink} package option.} but you still want to be able to
% switch language using \package{babel} or \package{polyglossia}, you
% would need something like:
% \begin{quote}
%   |\makeatletter|\\
%   |\crefformat{equation}{#2\cref@equation@name~(#1)#3}|\\
%   \dots\\
%   |\makeatother|
% \end{quote}
% and similarly for |\crefrangeformat|, |\crefmultiformat|,
% |\Crefformat|, etc.
%
% Note that if you define an empty cross-reference name for some type
% using an empty |\crefname|, e.g.\ for equations
% \begin{quote}
%   |\crefname{equation}{}{}|
% \end{quote}
% then the empty cross-reference name will be retained when switching
% languages. This is probably what you want anyway.
%
%
%
% \section{The \file{cleveref.cfg} File}
% If \package{cleveref} finds a \file{cleveref.cfg} file somewhere in the
% \LaTeX{} search path, it automatically loads any definitions found in
% that file. (For details of which directories \LaTeX{} searches, consult
% the documentation for your site's \TeX{} installation.) The main use of
% \file{cleveref.cfg} is to store any cross-reference format
% customisations that you want to use in every document you write, so
% that you don't have to include them explicitly in every document's
% preamble.
%
%
%
% \section{Poor Man's \package{cleveref}}
% Sometimes you may need to send your \LaTeX{} source to someone who
% can't or won't install the \package{cleveref} package themselves. For
% example, many academic journals accept papers in \LaTeX{} format, but
% only support a small subset of the packages available on CTAN. The
% \option{poorman} option was designed specifically to help in this
% situation.
%
% When the \option{poorman} option is supplied, your document will be
% processed as normal. But in addition, a |sed| script will automatically
% be written, containing rules for replacing all the \package{cleveref}
% commands with the \LaTeX{} code that they would produce, and using the
% standard |\ref| command to produce the cross-references themselves.
% I.e.\ the script rewrites your document as you would have done if you
% had had to do it manually!
%
% The advantage, of course, is that you \emph{don't} have to do it
% manually. Instead, you can use all the features of \package{cleveref},
% and once you've created a version of your document that you want to
% send elsewhere, you can process it through the |sed| script to
% completely remove the \package{cleveref} dependency. The recipient
% won't even realise you used \package{cleveref}!
%
% The |sed| script is written to the same directory as the (main)
% \LaTeX{} source file, and given the same name as that source file but
% with the extension \file{.sed}. To process your document through the
% script, all you need to do is run the following from your shell:
% \begin{quote}
%   sed -f \meta{name}\file{.sed} \
%   \meta{name}\file{.tex} \textgreater \meta{newname}\file{.tex}
% \end{quote}
% where \meta{name} is the name of the file containing your \LaTeX{}
% source file minus the \file{.tex} extension, and \meta{newname} is
% whatever you want to call the new version. \emph{Do not} make
% \meta{newname} the same as \meta{name}: it won't work. (It's in any
% case wise to keep the original \LaTeX{} source file containing the
% \package{cleveref} commands, in case you need to produce an updated
% version of your document in the future. Think of the
% \meta{newname}\file{.tex} file in the same way as a \file{DVI} file:
% something you can always reproduce from the original source.)
%
% If your document is composed of a number of separate \LaTeX{} source
% files, combined with |\include| commands, only one |sed| script will be
% generated, but you will need to run \emph {each} source file through
% that \emph{same} script (and probably modify the |\include| commands to
% match the new file names). However, using \package{babel}'s language
% switching commands in a document split across multiple separate source
% files is beyond the capabilities of the \package{poorman} option. You
% will almost certainly need to manually tweak the |sed| script in that
% case.
%
% Note that the \option{poorman} script cannot fully reproduce the
% typesetting of the original \package{cleveref} cross-references in all
% cases.\footnote{At least, not without resorting to inserting low-level
% \LaTeX{} code in your document, which would somewhat defeat the purpose
% of the \option{poorman} option.} In particular, if you're using the
% \package{hyperref} package (see \cref{sec:other_packages}) to turn
% cross-references into hyperlinks, any customisation of hyperlinks will
% be lost. And if you're using the \package{varioref} package (see
% \cref{sec:other_packages}), you may need to manually tweak the spacing
% in front of some of the \package{varioref} commands in the document
% produced by the |sed| script.
%
%
%
% \section{Interaction with Other Packages}
% \label{sec:other_packages}
% The \package{cleveref} package \emph{must} be loaded \emph{after} all
% other packages that don't specifically support it,\footnote{At the time
% of writing, the only packages I'm aware of that should be loaded after
% \package{cleveref} are the \package{hypdvips} and \package{autonum}
% packages.} i.e.\ the
% \begin{quote}
%   |\usepackage{cleveref}|
% \end{quote}
% line should usually be the last |\usepackage| command in your
% document's preamble.
%
% \package{Cleveref} tries as far as possible to minimise its impact on
% the standard \LaTeX{} cross-referencing machinery, allowing it to work
% alongside many of the other packages that also enhance \LaTeX{}'s
% cross-referencing features, though it can occasionally interact badly
% with packages that redefine the same core \LaTeX{} commands. Beyond
% peacefully co-existing with many packages, \package{cleveref} includes
% specific support for a number other packages, allowing it to integrate
% its clever cross-referencing features with the features provided by
% these packages: \package{babel}, \package{polyglossia},
% \package{hyperref}, \package{varioref}, \package{ntheorem},
% \package{amsthm}, \package{aliascnt}, \package{subfig},
% \package{algorithmicx}\footnote{The \package{algorithmic} package is
% \emph{not} supported.}, \package{algorithm2e}, \package{listings}.
%
% \package{Cleveref} implements a significantly enhanced version of the
% features found in the \package{fancyref} package, \package{ntheorem}'s
% \option{thref} option, and \package{varioref}'s |\labelformat| command.
% Although these features may (or may not) work correctly alongside
% \package{cleveref}, there is no good reason to use them when using
% \package{cleveref}, and their use is unsupported. (Note that
% \package{varioref} \emph{is} fully supported by \package{cleveref},
% just that \package{cleveref}'s features supersede \package{varioref}'s
% |\labelformat| feature. Similarly, \package{ntheorem} is fully supported
% and even recommended, only the \option{thref} option is superseded by
% \package{cleveref}.)
%
% \DescribeMacro{\thref}
% \DescribeMacro{\vref}
% \DescribeMacro{\Vref}
% \DescribeMacro{\vrefrange}
% \DescribeMacro{\Vrefrange}
% \DescribeMacro{\fullref}
% \DescribeMacro{\Fullref}
% In fact, if \package{ntheorem} is loaded with the \option{thref}
% option, \package{cleveref} redefines \package{ntheorem}'s |\thref|
% command for you, to be an alias for |\cref|. Similarly, if
% \package{varioref} is loaded, \package{cleveref} redefines the |\vref|,
% |\vrefrange|, |\fullref| commands and variants to instead use the
% \package{cleveref} features for cross-reference formatting, whilst
% retaining all the \package{varioref} page-referencing magic. You can
% continue to use the other \package{varioref} and \package{ntheorem}
% commands (other than |\labelformat| and the \option{thref} option)
% whilst using \package{cleveref}, as long as \package{cleveref} is
% loaded \emph{last}.
%
% \DescribeMacro{\vref*}
% \DescribeMacro{\Vref*}
% \DescribeMacro{\vrefrange*}
% \DescribeMacro{\Vrefrange*}
% \DescribeMacro{\fullref*}
% \DescribeMacro{\Fullref*}
% Note that, whilst in the business of redefining the \package{varioref}
% commands, \package{cleveref} seizes the opportunity to get rid of the
% irritating spacing behaviour of the |\vref| and |\Vref| commands,
% instead making it consistent with the other \package{cleveref}
% cross-referencing commands. This also frees up the starred variants of
% the \package{varioref} commands to be used for suppressing hyperlinks
% when the \package{hyperref} package is loaded, as usual.
% (Unfortunately, due to lack of support for this in \package{varioref},
% the page references will still sometimes be hyperlinks, even when using
% the starred variants. Go bug the \package{varioref} maintainer about
% this if you don't like it.)
%
% \package{Cleveref} is currently incompatible with the
% \package{mathtools} package's\linebreak[4] \option{showonlyrefs}
% option, which automatically labels only those equations that are
% cross-referenced. The \package{autonum} package provides a possible
% alternative, which implements similar features in a
% \package{cleveref}-compatible manner.
%
%
%
% \section{Known Bugs, Non-Bugs, and Possible Improvements}
% \label{sec:known_bugs}
%
% \subsection{Non-Bugs}\label{sec:non-bugs}
% The following are \emph{not} bugs. They are either intentional
% behaviour, unavoidable behaviour, or are caused by \LaTeX{}
% misunderstandings:
% \begin{itemize}
% \item If you are using both \package{varioref} and \package{hyperref},
%   \emph{make sure you are loading them in the correct order}, otherwise
%   cross-references will reference completely the wrong thing
%   \emph{without any warning in the \LaTeX{} output or log!} The
%   packages \emph{must} be loaded in the following order:
%   \package{varioref}, \package{hyperref}, \package{cleveref}.
% \item \package{Cleveref} on its own won't automatically infer the type
%   of theorem-like environment you're referring to in a cross-reference.
%   Cross-references to all theorem-like environments will use the same
%   name, ``theorem''. To allow the theorem type to be determined
%   automatically, you need to load either the \package{ntheorem} or the
%   \package{amsthm} package. Also note that all |\newtheorem|
%   definitions must be placed \emph{after} the \package{cleveref}
%   package is loaded.
% \item Due to the way \TeX{} parses arguments, you have to be a little
%   careful when using |\label| inside an optional argument to another
%   command. |\label|\marg{label} will work, but trying to pass an
%   optional argument |\label|\oarg{type}\marg{label} will fail. If you
%   want to pass an optional argument to |\label| whilst already within
%   an optional argument to some other command, you must surround the
%   entire label command with braces:
%   |{\label|\oarg{type}\marg{label}|}|. This crops up e.g.\ when adding
%   labels to subfigure subcaptions in the \package{memoir} document
%   class. A simpler solution in this particular case is to define the
%   label in the subfigure body, instead of in the subcaption.
% \item \package{Cleveref} will not work properly with the standard
%   \LaTeX{} |eqnarray| environment. There is no intention to fix this.
%   The |eqnarray| environment is poorly implemented, making it difficult
%   to get it to work properly with \package{cleveref}, and it's broken
%   any way. You're \emph{far} better off using the \package{amsmath}
%   replacements, such as |gather|, |align|, |multline| and |split|,
%   which \emph{do} work properly with \package{cleveref}. (See
%   \url{http://www.tug.org/pracjourn/2006-4/madsen/}).
% \item If you are using \package{babel}, you \emph{must still} pass the
%   appropriate language option to \package{cleveref}, as well as to
%   \package{babel}. Passing it to \package{babel} alone is \emph{not}
%   sufficient (you will get the default English cross-reference
%   formats). The best way to set the document language is as a global
%   option in the |\documentclass| line. (This is standard \LaTeX{} and
%   \package{babel} practice -- read up on \LaTeX{}'s option handling for
%   more detail.)
% \item \package{Cleveref} can't cope with active characters being
%   present in cross-reference label names. For example, if French
%   \package{babel} support is loaded, the commonly used ``:'' in label
%   names will often fail, spewing the usual random selection of
%   mysterious \TeX{} errors that accompany such deep-seated errors. The
%   solution is to avoid using active characters in label names. (You may
%   need to consult the \package{babel} documentation to discover which
%   active characters are defined in your language.)
% \item The \option{poorman} |sed| script loses any custom
%   \package{cleveref} hyperlink formatting you might have defined, and
%   does not always reproduce the original spacing around the
%   \package{varioref} commands when \package{varioref} is used. This is
%   not a bug; it is a side-effect of the intended purpose of the
%   \option{poorman} option. The philosophy behind \option{poorman} is to
%   replace \package{cleveref}'s enhanced cross-referencing with standard
%   \LaTeX{} cross-reference commands that are guaranteed to work with
%   any standard \LaTeX{} installation. Although it would be simple to
%   fix these ``bugs'', it's almost certainly impossible without using
%   low-level \LaTeX{} code that is unlikely to be supported by e.g.\
%   academic journals, thereby defeating the whole purpose of the
%   \option{poorman} option.
% \end{itemize}
%
%
% \subsection{Known Bugs and Work-Arounds}
% In rough order of significance:
% \begin{itemize}
% \item When both the \package{amsmath} \emph{and} \package{hyperref}
%   packages are loaded at the same time, the \package{cleveref}
%   cross-referencing commands do not work when used within section
%   titles. If anyone can figure out why, let me know! As a work-around,
%   use |\ref| within section titles when your document uses both
%   \package{amsmath} and \package{hyperref}.
% \item When using \package{varioref} and \package{hyperref} with
%   \package{cleveref}, the \package{cleveref}\linebreak[4]
%   \option{nameinlink} option will not cause the word ``page'' in the
%   page-reference part of a |\vref| (or other \package{varioref})
%   command to be included in the hyperlink, nor will the ``on the
%   previous page'' (or similar) text produced by |\vref| be hyperlinked.
%   This is not strictly speaking a \package{cleveref} issue. It is the
%   normal behaviour of the \package{hyperref}-enhanced version of
%   \package{varioref}'s |\vpageref| command, which \package{cleveref}
%   uses to produce the page references in its enhanced |\vref| command.
%   (This \emph{might} be improved in a future version by partially
%   overriding \package{hyperref}.)
% \item \package{Cleveref} doesn't know about the \package{subfloat}
%   package, so you have to revert to using |\ref| for cross-references
%   to sub-figures. (Might be fixed in a future version.)
% \item The \package{beamer} document class redefines the |\label|
%   command in a particularly devious way that breaks
%   \package{cleveref}'s optional argument to that command. (Might be
%   fixed in a future version.)
% \item \package{Cleveref} is incompatible with the \option{showonlyrefs}
%   option of the \package{mathtools} package, though it should be
%   compatible with the rest of \package{mathtools}. (Might be fixed in a
%   future version.) The \package{autonum} package, which provides
%   similar functionality and \emph{is} designed to be
%   \package{cleveref}-compatible, is a possible alternative.
% \item \package{Cleveref} assumes that counters are only ever reset by
%   the standard sectioning commands (|\chapter|, |\section|, etc.). If
%   this is not the case, the automatic compression of consecutive
%   cross-references into a reference range may be incorrect. Making this
%   more flexible would be a simple task, but so far there doesn't seem
%   to be much need for it.
% \end{itemize}
%
%
% \subsection{Possible New Features and Improvements}
% \label{sec:new-features}
% In no particular order:
% \begin{itemize}
% \item The \option{poorman} option could be enhanced to allow a choice
%   of scripting language rather than just |sed| (e.g.\ |awk|, |perl|,
%   \dots?), but these are unlikely to be much better for those apt to
%   complain about the use of |sed|. The portable option would be to
%   output a \TeX{} ``script'', but this would be \emph{much} more
%   work\footnote{\LaTeX{} \emph{really} isn't suited to that kind of
%   pattern matching task -- just take a look at the code for escaping
%   regexp special characters in this package!} than I'm prepared to
%   invest.
% \item \package{Cleveref} doesn't include support for all languages yet.
%   Any contributions of translations for missing languages are most
%   welcome! If you can contribute definitions for a missing language,
%   ideally you should add them below the existing ones in the
%   implementation (using those as a model), generate a patch against the
%   original \package{cleveref.dtx} file, and send the patch by email to
%   the package author. However, if you don't know how to produce a
%   patch, you can instead just send the translations as a plain text
%   file.

% \section{Implementation}
% Essentially, the core of the implementation consists of writing an
% extra piece of information --- the label ``type'' --- to the \file{aux}
% file, and defining \cmd{\cref} commands which use this extra
% information to typeset the cross-reference.
%
% The least invasive previous implementation of this kind of thing seems
% to be that used by the \package{varioref} package. Namely, to redefine
% the \cmd{\refstepcounter} command so that the \cmd{\@currentlabel}
% macro, which usually just contains the typeset version of the counter,
% now contains the additional type information.
%
% However, even less invasive than \package{varioref}'s implementation is
% to leave \cmd{\@currentlabel} alone, and define a new
% \cmd{\cref@currentlabel} macro to hold the extra information. (In fact,
% we store three extra pieces of information: the type, the counter value
% itself, and the value of the counter that causes the label's counter to
% be reset, which we call the ``prefix'' from now on.) The standard
% \cmd{\@currentlabel} contents eventually get written to the \file{aux}
% file as an argument to \cmd{\newlabel} by the usual \LaTeX{} label
% mechanisms. In order to also get the information in
% \cmd{\cref@currentlabel} into the \file{aux} file, we have to redefine
% the \cmd{\label} macro so that it writes \emph{two} \cmd{\newlabel}
% lines to the \file{aux} file for \emph{each} label: the standard one,
% plus an additional one which contains the extra information in
% \cmd{\cref@currentlabel}. The additional \cmd{\newlabel} line has the
% suffix |@cref| added to the label name. Thus the extra information in
% \cmd{\cref@currentlabel} will end up in \cmd{\r@\meta{label}@cref} when
% the \file{aux} file is re-read on the next pass.
%
% Doing things this way involves less hacking to get everything else
% working again, since the standard cross-reference mechanism and
% \cmd{\ref} command are left entirely intact. \package{Cleveref} can
% then do what it likes with its own parallel set of labels, without
% getting in the way of other packages that play around with the
% cross-reference mechanism. The only downside is the additional memory
% resources this uses, but on modern \TeX{} implementations this is
% unlikely to be a problem.
%
%
% \subsection{Redefinitions of \LaTeX{} Kernel Macros}
% \begin{macro}{\refstepcounter}
% \begin{macro}{\cref@currentlabel}
% \begin{macro}{\cref@old@refstepcounter}
%   We store the original \cmd{\refstepcounter} in
%   \cmd{\cref@old@refstepcounter}, then redefine \cmd{\refstepcounter}
%   so that it first calls the old version to define the standard
%   \cmd{\@currentlabel} macro, before defining \package{cleveref}'s
%   \cmd{\cref@currentlabel}, which contains the extra information. The
%   cross-reference ``type'' stored in \cmd{\cref@currentlabel} is usually
%   inferred from the counter. This can be overridden by aliasing the
%   counter name to a different type using \cmd{\crefalias}. The new
%   \cmd{\refstepcounter} can also take an optional argument, which
%   always overrides the type.
%    \begin{macrocode}

% \end{macro}
%
%
% \begin{macro}{\label}
% \begin{macro}{\cref@label}
% \begin{macro}{\label@optarg}
% \begin{macro}{\label@noarg}
%   We redefine the \cmd{\label} command to make it define \emph{two}
%   labels each time it's called: the standard one, and an additional
%   \package{cleveref}-specific one with the suffix |@cref| added to the
%   label name, which contains the extra information from
%   \cmd{\cref@currentlabel}. We call the original \cmd{\label} command,
%   stored in \cmd{\cref@old@label}, to write the standard label to the
%   \file{aux} file. However, to avoid other packages messing around with
%   the content of the parallel set of \package{cleveref}-specific
%   labels, we write those directly to the \file{aux} file ourselves. We
%   also allow \cmd{\label} to take an optional argument which overrides
%   the default reference type in \cmd{\cref@currentlabel}.
%
%   The redefinition of \cmd{\label} has to be postponed until the
%   beginning of the document because some other packages postpone their
%   own \cmd{\label} redefinitions too, and we need to override their
%   redefinitions.

%   Footnotes don't use the \cmd{\refstepcounter} mechanism, but instead
%   set\linebreak[4] \cmd{\@currentlabel} directly inside the footnote
%   insertion item. Thus we need to explicitly set
%   \cmd{\cref@currentlabel} in footnotes. To avoid the definition
%   spilling out of the footnote, we need to set it inside
%   \cmd{\insert}'s implicit insertion item grouping level. To this end,
%   we add the explicit \cmd{\cref@currentlabel} redefinition to
%   \cmd{\@makefntext}, which gets called from within \cmd{\insert} by
%   both \cmd{\@footnotetext} and \cmd{\@mpfootnotentext}.

% \begin{macro}{\newtheorem}
%   A \cmd{\newtheorem} command provides sufficient information to
%   automatically define a reasonable cross-reference name for
%   theorem-like environments (\package{ntheorem}'s \option{thref} does
%   essentially this). So we modify \cmd{\newtheorem} (actually, the
%   lower-level \cmd{\@othm}, \cmd{\@xnthm} and \cmd{\@ynthm} macros) so
%   that it does so. We do this in such a way that default definitions or
%   explicit \cmd{\crefname} definitions for theorem-like environments
%   override those produced automatically by our modified
%   \cmd{\newtheorem}.
%
%   The catch is that, although the \cmd{\newtheorem} command provides
%   the singular form, there's no way of reliably deducing the correct
%   plural form. Rather than implement some half-baked attempt at this
%   which will be wrong more often than it's right (especially in
%   languages other than English) and generally cause more trouble than
%   it's worth, we simply define the singular form but leave the plural
%   form undefined. If the latter is ever needed, it will produce a
%   ``undefined cross-reference type'' warning, prompting the author to
%   provide an appropriate \cmd{\crefname} definition themselves.
%
% \begin{macro}{\@othm}
% \begin{macro}{\@xnthm}
% \begin{macro}{\@ynthm}
%   After sorting out its arguments, \cmd{\newtheorem} calls one of
%   \cmd{\@othm}, \cmd{\@xthm} or \cmd{\@ythm}. We add automatic
%   definitions of \cmd{\cref@\meta{type}@name} and\linebreak[4]
%   \cmd{\Cref@\meta{type}@name} to all three of these, and add the
%   theorem-like environment to the list of cross-reference types that
%   need to be defined from components at |\||begin{document}|. Since we
%   want explicit \cmd{\crefname}'s to override these automatic
%   definitions, we store the definitions in
%   \cmd{\cref@\meta{type}@name@preamble}, which are processed at
%   |\||begin{document}|) if they haven't been overridden. The default
%   definitions also get stored in \cmd{\cref@\meta{type}@name@preamble}
%   later on, so they too will override these automatic definitions,
%   which is what we want.
%
%   All this means that these automatic \cmd{\newtheorem} definitions
%   will only work when \cmd{\newtheorem} is used in the preamble.
%   However, this is also true of (new) cross-reference types defined
%   using \cmd{\crefname}, so it doesn't seem worth the significant
%   effort of getting the automatic definitions to work within the
%   document body.

%   Define some utility macros for extracting label, type, and counter

%   to the \file{aux} file and stored in \cmd{\r@\meta{label}@cref} when
%   this is re-read on the next pass. Some other packages commandeer the
%   referencing system to write label information to the \file{aux} file
%   for other purposes, and probably use \cmd{\ref} to recover it later.
%   We still want them to work, so our utility macros must cope with the
%   type information being absent. However, since we need them to be
%   fully expandable in various places, and \cmd{\@ifnextchar} is
%   definitely \emph{not} fully expandable, we use the work-around of
%   having the macros store their result in another macro, whose name is
%   passed as the second argument. This other macro \emph{will} then be

% \begin{macro}{\cref@constructprefix}
%   The \cmd{\cref@constructprefix} macro constructs the prefix
%   information stored in \cmd{\cref@currentlabel} (retrieved using
%   \cmd{\cref@getprefix}). This information consists of the numerical
%   value of each counter that's involved in resetting the label's
%   counter, i.e.\ it contains the numerical values of the chapter,
%   section, subsection\dots{} numbers that (ought to) make up the
%   formatted label produced by \cmd{\the\meta{counter}}. E.g.\ if
%   \cmd{\theequation} produces ``B.1.3'', this utility macro will return
%   ``2,1'' (the ``3'' corresponds to the equation number itself, which
%   is stored separately in \cmd{\cref@currentlabel}). The first argument
%   is the counter in question; the return value is stored in the second
%   argument, which should be a macro name.
%
%   The real work is done by the recursive \cmd{\@cref@constructprefix}
%   macro, which works its way upwards through the counters' reset lists
%   until it reaches a counter that isn't reset by any other.

%   of digits or letters in the second argument.

%   tagged onto the end of the generated macro names. Note that

% \subsection{Support for Other Packages}
%
% \subsubsection{\package{hyperref} support}
% \begin{macro}{hyperref}
%   If the \package{hyperref} package is loaded, we add hyperlink
%   support to \package{cleveref}. Since \package{hyperref} messes around
%   with some of the same \LaTeX{} internals as we do, we also have to
%   override some of its redefinitions so that they work with
%   \package{cleveref}.
%    \begin{macrocode}
\let\if@cref@hyperrefloaded\iffalse%
\let\cref@addtoreset\@addtoreset%
\@ifpackageloaded{hyperref}{%
  \@ifpackagewith{hyperref}{implicit=false}{%
    \let\if@cref@hyperrefloaded\iftrue%
    \PackageWarning{cleveref}{hyperref package loaded with
      implicit=false option - disabling cleveref's hyperref support.
      This situation is not supported by cleveref, and there's no guarantee
      anything will work. You're on your own!}%
  }{%
    \let\if@cref@hyperrefloaded\iftrue%
    \PackageInfo{cleveref}{`hyperref' support loaded}%
%    \end{macrocode}
% \package{hyperref} redefines the \LaTeX{} kernel \cmd{\@addtoreset}
% macro (sigh), but we sometimes need the vanilla version without the
% \package{hyperref} shennanigans. \package{hyperref} saves the
% original in \cmd{\HyOrg@addtoreset}. So we create yet
% \emph{another} version called \cmd{\cref@addtotreset}, which is always
% let to the original \cmd{\@addtoreset}, whereever that's found.
%    \begin{macrocode}
    \let\cref@addtoreset\HyOrg@addtoreset%
%    \end{macrocode}
% \begin{macro}{\cref@hyperlinkname}
% \begin{macro}{\cref@hyperlinkurl}
%   We define a utility macro to extract the hyperlink supplied by
%   \package{hyperref} (via the \file{aux} file). Note that
%   \package{hyperref} adds the hyperlink info to the standard
%   \cmd{\newlabel} line in the \file{aux} file, so we have to retrieve
%   it from the standard \cmd{\r@\meta{label}}, \emph{not} the one
%   suffixed with |@cref| that we've created ourselves.
%    \begin{macrocode}
    \def\cref@hyperlinkname#1{\expandafter\expandafter\expandafter%
      \@fourthoffive\csname r@#1\endcsname}%
    \def\cref@hyperlinkurl#1{\expandafter\expandafter\expandafter%
      \@fifthoffive\csname r@#1\endcsname}%
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\cref@hyperlink}
%   Because of the way the cross-referencing formatting commands work, we
%   will need to use a delimited argument to specify the text to be
%   turned into a hyperlink. So we define a variant of
%   \package{hyperref}'s \cmd{\hyper@@link} command that takes the
%   hyperlink text as an argument delimited by |\@nil|, instead of a
%   standard argument. (We only ever need the |link| hyperlink type in
%   \package{cleveref}, so we don't bother providing \cmd{\hyper@@link}'s
%   optional argument.)
%    \begin{macrocode}
    \def\cref@hyperlink#1#2#3\@nil{\hyper@@link[link]{#1}{#2}{#3}}%
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\H@refstepcounter}
%   The \package{hyperref} package stores the original
%   \cmd{\refstepcounter} definition as\linebreak[4]
%   \cmd{\H@refstepcounter}. Unfortunately, it plasters
%   \cmd{\H@refstepcounter} all over the place, sometimes bypassing
%   \cmd{\refstepcounter} entirely. So we're forced to modify
%   \cmd{\H@refstepcounter} itself, in order to ensure that the extra
%   information we need is stored in \cmd{\cref@currentlabel}.
%    \begin{macrocode}
    \let\cref@old@H@refstepcounter\H@refstepcounter%
    \def\H@refstepcounter#1{%
      \cref@old@H@refstepcounter{#1}%
      \cref@constructprefix{#1}{\cref@result}%
      \@ifundefined{cref@#1@alias}%
        {\def\@tempa{#1}}%
        {\def\@tempa{\csname cref@#1@alias\endcsname}}%
      \protected@edef\cref@currentlabel{%
        [\@tempa][\arabic{#1}][\cref@result]%
        \csname p@#1\endcsname\csname the#1\endcsname}}%
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\refstepcounter@noarg}
% \begin{macro}{\refstepcounter@optarg}
%   \package{hyperref}'s \cmd{\refstepcounter}, which ends up stored in
%   our\linebreak[4] \cmd{\cref@old@refstepcounter}, already calls
%   \cmd{\H@refstepcounter}, and we just redefined the latter to store
%   the extra information. So we only need to change
%   \cmd{\cref@currentlabel} in \emph{our} \cmd{\refstepcounter} if an
%   optional argument was supplied. Note that, in this case, the
%   mechanism for setting \cmd{\cref@currentlabel} is slightly different
%   than it is without \package{hyperref}: \cmd{\cref@currentlabel} first
%   gets set by our modified \cmd{\H@refstepcounter}, which gets called
%   via \package{hyperref}'s original version, as stored in
%   \cmd{\cref@old@refstepcounter}. The version of
%   \cmd{\cref@refstepcounter@optarg} defined below then overrides the
%   label type.
%    \begin{macrocode}
    \let\refstepcounter@noarg\cref@old@refstepcounter%
    \def\refstepcounter@optarg[#1]#2{%
      \cref@old@refstepcounter{#2}%

          \cref@currentlabel\@nil{\@tempa}}}%
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\appendix}
%   We again make \cmd{\appendix} redefine things so that the label type
%   for chapters or sections is exceptionally overridden and set to
%   ``appendix'' instead. But this time, it is \cmd{\H@refstepcounter}
%   that needs to be redefined.

% \subsubsection{\package{varioref} support}
% \begin{macro}{varioref}
%   If \package{varioref} is loaded, we redefine its commands to use
%   \cmd{\cref} instead of \cmd{\ref} to produce the reference. Since
%   \cmd{\cref} can cope with multiple references, we extend the page
%   referencing magic of \cmd{\vref} et al.\ to use \cmd{\cpageref}
%   instead, assisted by \cmd{\@@setvpageref} and \cmd{\@vpagerefrange}
%   (which typeset page references using \package{varioref} commands).
%   The former takes care of multi-references, the latter take care of
%   the \package{varioref} page referencing magic.

%    \end{macrocode}
%
%
% \begin{macro}{\cref@old@@vpageref}
%   Unfortunately, \package{varioref}'s |\@@vpageref| macro calls a
%   |\vref@label| \emph{before} it typesets the page reference. The
%   |\protected@write| within |\vref@label| seems to prevent an |\unskip|
%   command coming after the |\vref@label| from removing any space that
%   was inserted before the |\vref@label|. This means that setting a
%   |\reftext|\meta{x} command to |\unskip| won't work; it won't properly
%   remove any preceding space in the event that an empty page reference
%   is typeset.
%
%   This didn't matter in the original \package{varioref} implementation,
%   because it \emph{always} removed any preceding space, then inserted
%   its own space \emph{after} the |\vref@label|, which the |\unskip|
%   could then gobble. But we want to get rid of this irritating
%   always-space-gobbling behaviour here. So we have to redefine
%   |\@@vpageref| (here renamed |\cref@old@@vpageref|) in order to move
%   the |\vref@label| to the end of the macro, after the page reference
%   has been typeset. We also remove the |\unskip| from the start of
%   |\@@vpageref|.

% \begin{macro}{\cref@@vpageref}
%   We first enhance the core \package{varioref} |\vpageref| macro to
%   allow it to cope with lists of page references. This is done by
%   defining our version in terms of \package{cleveref}'s \cmd{\cpageref}
%   command, which handles multi-references, but telling \cmd{\cpageref}
%   to typeset the actual page references themselves using
%   \package{varioref}'s own page-referencing commands. (The alternative
%   version of \cmd{\vpagerefrange} is there to facilitate later
%   redefinitions.)
%
%   Most of the work is done by defining suitable |\@setvpageref| etc.\
%   commands (below), called as appropriate by our ever-faithful
%   \cmd{\@cref} work-horse. We only make use of one of the optional
%   arguments to the original \package{varioref} |\@@vpageref| macro,
%   which we store here in \cmd{\cref@@vpageref} for later.
%    \begin{macrocode}

% \begin{macro}{\cref@fullref}
%   Now we define \package{cleveref}-enhanced versions of the other
%   \package{varioref} cross-\linebreak[4]referencing commands, which use
%   \cmd{\cref} et al.\ to type set the cross-references, and the
%   \package{cleveref}-enhanced \cmd{\vpageref} et al.\ to typeset page
%   references.
%
%   The original \cmd{\vref} command passes an empty first argument to
%   \cmd{\@@vpageref}, to omit the page reference if it refers to the
%   current page. In our case, we only want to omit it if it's the sole
%   page reference we're printing; otherwise we need to print it even if
%   it refers to the current page. This is taken care of by
%   \cmd{\cref@patchreftexts} (which gets called further down). For this
%   mechanism, it's more convenient to pass \cmd{\reftextcurrent} as the
%   first argument but temporarily redefine it to be empty, instead of
%   passing an empty first argument to \cmd{\cref@@vpageref}.

% \begin{macro}{\@setvpageref}
%   The \cmd{\@setvpageref} macro is called by \cmd{\@cref} to typeset
%   page references using \package{varioref} commands, tweaked to work
%   with the enhanced \package{cleveref} page-referencing features.
%   |#1| is the reference itself. |#2| is either empty if we're
%   typesetting a single page reference, or one of |@first|, |@second|,
%   |@middle| or |@end|, identifying where the page reference comes in a
%   multi-reference. We only make use of one of the optional arguments to

%   references, as any preceding space then is part of the preceding
%   conjunction, and should be strictly respected. But, since we're

% \begin{macro}{\label}
% \begin{macro}{\label@in@display}
%   The \package{amsmath} package redefines the \cmd{\label} command
%   within equation environments, so if it is loaded we have to extend
%   the behaviour to support the optional argument. With
%   \package{amsmath}, the original \cmd{\label} command is stored in
%   \cmd{\ltx@label}, and \cmd{\label@in@display} replaces \cmd{\label}
%   inside equations. \cmd{\label@in@display} just saves the label for
%   later, and defining it is left until the end of the equation, when
%   \cmd{\ltx@label} is finally called.
%
%   To allow \cmd{\label} within equations to support an optional
%   argument, we first store the original \cmd{\label@in@display} and the
%   new \cmd{\label} macro we defined above (since \cmd{\label} will be
%   clobbered inside equations). Then we redefine \cmd{\label@in@display}
%   so that it wraps all its arguments, including any optional argument,
%   in an extra set of braces. These are stripped away again by
%   \cmd{\ltx@label} before calling the \package{cleveref} \cmd{\label}
%   command we defined previously (saved in \cmd{\cref@label}). As
%   before, we must postpone the redefinition of \cmd{\label} until the
%   beginning of the document, since other packages do so.

% \begin{macro}{\measure@}
% \begin{macro}{\gmeasure@}
%   The \package{amsmath} multi-line equation environments scan their
%   bodies twice: once to measure, once to typeset. In the measure phase,
%   the \cmd{\label} command is disabled by letting it to \cmd{\@gobble}.
%   But this isn't sufficient to gobble all the arguments any more if an
%   optional argument is supplied to our new \cmd{\label}, so we have to
%   modify the \package{amsmath} measuring commands so that they let
%   \cmd{\label} to \cmd{\cref@gobble@optarg} instead.
%
%   Unfortunately, \package{amsmath} wasn't designed with redefinitions
%   of \cmd{\label} in mind, so there appears to be no safe way of doing
%   this other than copying the \package{amsmath} definitions and making
%   the modification directly in the macro's code. This is a recipe for
%   future chaos if these commands are ever modified in a new version of

%   In order for |subequations| to be sorted properly, \package{cleveref}
%   needs to know that the |equation| counter is effectively reset by the
%   |parentequation| counter within the |subequations| environment. This
%   isn't how |amsmath| implements subequations (for obvious reasons!),
%   but we harmlessly add the |equation| counter to the |parentequation|
%   counter's reset list \emph{within} |subequations| environments, so
%   that \package{cleveref}'s sorting mechanism can figure things out. We
%   also harmlessly make sure |parentequation| is reset by the same
%   counter as |equation|.
%
%   We also want to treat subequations as a separate cross-reference type
%   from equations. However, \package{amsmath} still uses the |equation|
%   counter for subequations, not a separate ``subequation'' counter. We
%   therefore temporarily alias |equation| to |subequation| within

%
% \begin{macro}{\ALG@step}
%   We modify \package{algorithmicx}'s \cmd{\ALG@step} macro, which
%   increments the line number, so that it stores the necessary
%   information in \cmd{\cref@currentlabel}. \cmd{\ALG@step} already
%   increments the line number counter \cmd{\ALG@line} using
%   \cmd{\addtocounter}, but to get \package{cleveref} support working,
%   it's cleaner to hook into the \cmd{\refstepcounter} mechanism, so we
%   first decrement the counter and then re-increment it using
%   \cmd{\refstepcounter}.
%    \begin{macrocode}
  \g@addto@macro\ALG@step{%

%
% \begin{macro}{\ALG@beginalgorithmic}
%   However, this is not yet sufficient. The \cmd{\refstepcounter} above
%   is called within a group, so the resulting \cmd{\cref@currentlabel}
%   definition will not persist beyond the end of the group. To transfer
%   the information to the ``outside'', we follow \package{algorithmicx}'
%   own method for getting the label information into
%   \cmd{\@currentlabel}: we define \cmd{\cref@currentlabel} within
%   |algorithm| environments to refer specifically to macros that store
%   the line number information. The package conveniently supplies a
%   \cmd{\ALG@beginalgorithmic} hook, so we make use of it here.
%    \begin{macrocode}
  \g@addto@macro\ALG@beginalgorithmic{%
    \def\cref@currentlabel{%
      [line][\arabic{ALG@line}][\cref@currentprefix]\theALG@line}}%

%
% \subsubsection{\package{listings} support}
% \begin{macro}{listings}
%   To support cross-references to listings produced by the
%   \package{listings} package, all we need to do is alias the counter it
%   uses, \cmd{\lstnumber}, to the ``listing'' cross-reference type.
%    \begin{macrocode}
  \@ifpackageloaded{listings}{%
    \PackageInfo{cleveref}{`listings' support loaded}%
    \crefalias{lstlisting}{listing}%
    \crefalias{lstnumber}{line}%
%    \end{macrocode}
%
% However, supporting cross-references to the line numbers is
% unfortunately a little more complicated than simply aliasing the
% ``lstnumber'' counter to the ``line'' cross-reference type (above).
% \package{listings} calls \cmd{\refstepcounter} from its
% \cmd{\lsthk@EveryPar} hook. But the hook macro is expanded inside a
% group. So that \cmd{\refstepcounter} call is completely useless:
% neither the \cmd{\@currentlabel} nor the \cmd{\cref@currentlabel}
% definitions make it out of the group, so they have no effect on
% \cmd{\label} definitions!
%
% To make line labels work, \package{listings} sets \cmd{\@currentlabel}
% to \cmd{\thelstnumber} at the beginning of a listing, via the
% \cmd{\lsthk@Init} hook, and it is \emph{this} (and not
% \cmd{\refstepcounter}) which causes the current line number to be
% picked up by \cmd{\label}s. To get line numbers working with
% \package{cleveref} too, we need to replicate this for
% \cmd{\cref@currentlabel}, which is what the following hook code does.
%
% \begin{macro}{\lsthk@Init}
% \begin{macro}{\lsthk@EveryPar}
%    \begin{macrocode}

%
% \subsubsection{\package{algorithm2e} support}
% \begin{macro}{algorithm2e}
%   When \package{hyperref} is not loaded, all we need to do to support
%   the \package{algorithm2e} package is to alias its counters,
%   \cmd{\algocf}, \cmd{AlgoLine} and \cmd{\algocfline}, to the
%   ``algorithm'' and ``line'' cross-reference types.

% When \package{hyperref} \emph{is} loaded, \package{algorithm2e} does

% \cmd{\H@refstepcounter}, so \cmd{\cref@currentlabel} never gets
% updated. To fix this, we have to hack its \cmd{algocf@nl@sethref} macro
% to update \cmd{cref@currentlabel} along with \cmd{@currentlabel}.

% \subsubsection{\package{subfig} support}
% \begin{macro}{subfig}
%   The \package{subfig} package modifies \cmd{\refstepcounter} within
%   floats. Most of the time, this isn't a problem for
%   \package{cleveref}, as \package{subfig}'s modified
%   \cmd{\refstepcounter} calls \package{cleveref}'s version after it's
%   done its stuff. However, this breaks support the
%   \cmd{\refstepcounter} optional argument, so we fix that here.
%
%   \package{Subfig} also redefines \cmd{\label} within subfloats,
%   breaking \package{cleveref}'s optional argument. We also fix that.
%    \begin{macrocode}
\@ifpackageloaded{subfig}{%
  \PackageInfo{cleveref}{`subfig' support loaded}%

%
% \begin{macro}{\refsteponlycounter}
%   \package{subfig} replaces \cmd{\refstepcounter} with
%   \cmd{\refsteponlycounter} within floats, which calls the saved
%   \package{cleveref} \cmd{\refstepcounter} after doing some extra
%   \package{subfig}-related processing. We redefine
%   \cmd{\refsteponlycounter} so that passing it an optional argument
%   bypasses \package{subfig}'s code entirely and just calls the
%   \package{cleveref} code directly. Since only
%   \package{cleveref}-specific commands will ever pass an optional
%   argument to \cmd{\refstepcounter}, this won't affect
%   \package{subfig}'s use of \cmd{\refstepcounter}. We have to postpone
%   this redefinition until the beginning of the document because
%   \package{subfig} does.
%    \begin{macrocode}

% \end{macro}
%
% \begin{macro}{\sf@sub@label}
% \begin{macro}{\sf@old@label}
% \begin{macro}{\cref@old@label}
%   Inside a subfloat, \package{subfig} captures the current \cmd{\label}
%   definition in \cmd{\sf@oldlabel}, then replaces \cmd{\label} with
%   \cmd{\subfloat@label}, which does additional argument and
%   subfloat-related processing before calling \cmd{\sf@oldlabel}. This
%   breaks \package{cleveref}'s \cmd{\label} optional argument.
%
%   We need to insert an extra layer of processing into the chain of
%   redefined \cmd{\label} macro calls, to process \package{cleveref}'s
%   optional argument. We do this by redefining \package{subfig}'s
%   \cmd{\sf@sub@label} command to process \package{subfig}'s optional
%   argument (which uses parentheses rather than square brackets) as usual,
%   but then have it call \cmd{\cref@label} which stores
%   \package{cleveref}'s \cmd{\label} command (recall that we're inside a
%   subfloat here, where \package{subfig} has overridden the \cmd{\label}
%   macro itself), to process \package{cleveref}'s own \cmd{\label}
%   optional argument.
%
%   \cmd{\cref@label} would normally call the original \cmd{\label}
%   definition stored in \cmd{\cref@old@label}, whereas here we want it
%   to instead call \cmd{\sf@@sub@label}, the next layer of the
%   \package{subfig} \cmd{\label} macro stack, otherwise we bypass the
%   rest of the \package{subfig} processing and break it. So we
%   temporarily let \cmd{\cref@old@label} to \cmd{\sf@@sub@label}, so
%   that \cmd{\cref@label} hands back to \package{subfig}'s \cmd{\label}
%   processing when done. (We're inside a group, so \cmd{\cref@old@label}
%   gets restored at the end of the subfloat.)
%
%   The final issue is that \package{subfig} captures the original
%   \cmd{\label} definition in \cmd{\sf@oldlabel} at the beginning of the
%   subfloat. But this captures \package{cleveref}'s
%   definition,\footnote{Actually, because \package{subfig} always loads
%   the \package{caption} package, it captures \package{cleveref}'s
%   \package{caption}-related redefinition of \cmd{\label}.} instead of
%   the original \cmd{\label} definition that needs to be called after
%   \package{subfig} has finished its stuff. So, we let \cmd{\sf@oldlabel}
%   to \cmd{\cref@old@label} before redefining the latter, so that the
%   \package{subfig} \cmd{\label} stack calls the right thing once it's
%   done its own processing. Oof!

% \subsubsection{\package{memoir} subfig support}
% \begin{macro}{memoir}
%   We try to stay out of \package{memoir}'s way as much as possible, by
%   using a separate set of parallel label definitions for
%   \package{cleveref}, and leaving the standard labels alone for
%   \package{memoir} and other packages to use as normal. The one
%   remaining point of contention is the \cmd{\label} command itself.
%
% \begin{macro}{\sf@memsub@label}
% \begin{macro}{\@memoldlabel}
% \begin{macro}{\cref@old@label}
%   \package{memoir} contains its own internal re-implementation of
%   \package{subfig}, which redefines \cmd{\label} in a very similar way.
%   We therefore have to replicate the \package{subfig} support for
%   \package{memoir}'s internal re-implementation. (We have to postpone
%   the redefinitions until the beginning of the document because

% \subsubsection{\package{caption} support}
% \begin{macro}{caption}
%   The \package{caption} package redefines \cmd{\label} within floats.
%   Since version 3.2c, it is careful to redefine \cmd{\label} in a way
%   that doesn't break any optional arguments introduced by other
%   packages (such as \package{cleveref}'s), so we no longer need to add
%   any compatibility hacks.
%
%   Earlier versions of \package{caption} do break \package{cleveref}'s
%   optional argument, however, so we have to fix things here for those
%   versions.
%    \begin{macrocode}

%
% \begin{macro}{\cref@old@caption@xlabel}
% \begin{macro}{\cref@old@label}
% \begin{macro}{\cref@ORI@label}
% \begin{macro}{\caption@ORI@label}
%   We fix the \cmd{\label} argument parsing by redefining
%   \cmd{\caption@xlabel}, the macro which \cmd{\label} is let to inside
%   floats, to juggle around the various \package{cleveref} and
%   \package{caption} \cmd{\label}-processing macros so that everything
%   ultimately gets processed correctly.
%
%   \cmd{\cref@label} stores \package{cleveref}'s \cmd{\label}
%   redefinition (recall that we're inside a float here, where
%   \cmd{\label} itself has been redefined by \package{caption}).
%   \cmd{\cref@label} processes \package{cleveref}'s optional
%   \cmd{\label} argument, if any. It then calls \cmd{\cref@old@label}.
%   But we've let that to \cmd{\cref@old@caption@xlabel}, which stores
%   the original \cmd{\caption@xlabel}. So the net effect is to insert an
%   extra layer of optional argument processing between \cmd{\label} and
%   \cmd{\caption@xlabel}, which can then proceed as before.
%
%   The final issue is that \package{caption} captures the original
%   \cmd{\label} definition in \cmd{\caption@ORI@label}, but this picks
%   up the \package{cleveref} redefinition, which is not what we want. So
%   we let \cmd{\caption@ORI@label} to the original \cmd{\label}
%   definition as captured by \package{cleveref}. Usually, that's stored
%   in \cmd{\cref@old@label}, but we've temporarily redefined that. So we
%   need to save what was originally preserved in \cmd{\cref@old@label}
%   in \cmd{\cref@ORI@old@label}, and make \cmd{\caption@ORI@label} call

% \subsubsection{\package{aliascnt} support}
% \begin{macro}{aliascnt}
%   For the \package{aliascnt} trick described in \cref{sec:label_type}
%   of the documentation to work, we have to inform \package{cleveref}
%   about how aliased counters get reset. \package{aliascnt}'s
%   \cmd{\newaliascnt} command doesn't add the aliased counter to any
%   reset list, but if the counter it's aliased to gets reset, the
%   aliased counter will get reset too. In order for \package{cleveref}
%   to correctly sort cross-references to the aliased counter, we have to
%   add that counter to the appropriate reset list, even though that
%   isn't necessary to actually reset the counter itself. We add this to
%   the \cmd{\newaliascnt} command.
% \end{macro}

% \subsection{Poor Man's \package{cleveref}}
% \begin{macro}{poorman}
%   The \option{poorman} option causes a |sed| script to automatically be
%   written. When the original \LaTeX{} source file is processed through
%   this script, it strips out all the \package{cleveref} commands,
%   typesetting all the reference formatting explicitly, and using the
%   standard \cmd{\ref} and \cmd{\pageref} commands to produce the
%   references themselves.
% \end{macro}

\DeclareOption{poorman}{%
  \PackageInfo{cleveref}{option `poorman' loaded}%
%    \end{macrocode}
%
%
% \begin{macro}{\cref@poorman@text}
%   Define global macro \cmd{\cref@poorman@text} to store the text
%   produced by the \cmd{\cref} commands, and open an output stream for
%   writing the script before starting to process the document body.
%    \begin{macrocode}
  \gdef\cref@poorman@text{}%

% \end{macro}
%
%
% \begin{macro}{select@language}
% \begin{macro}{foreign@language}
%   If \package{babel} is loaded, we add to the \cmd{\select@language}
%   and \cmd{\foreign@language} commands to make them write substitution
%   rules to the script that replace the cross-reference name and
%   conjunction component macros with the appropriate language-dependent
%   names. We use |sed| line-number addresses in the rules to ensure they
%   are only applied to the regions in which that particular language was
%   in use.
%
%   Note that we write substitution rules for the \emph{previous}
%   language block when the language is changed, because we need the
%   rules to appear in the script \emph{after} all the cross-reference
%   substitution rules for that language block. \cmd{\cref@inputlineno}
%   stores the input-file line-number of the start of the previous
%   language block.
%
%   We postpone the redefinitions until the beginning of the document not
%   only to ensure that they don't get clobbered by other package's
%   redefinitions, but also because we don't want the redefinitions to
%   take effect until after \package{babel} has called
%   \cmd{\selectlanguage} for the main language (remember, the
%   substitution rules for this first language block will get written at
%   the next language change).
%
%   Note that, since we're writing to the script file within
%   \cmd{\AtBeginDocument} and \cmd{\AtEndDocument}, this code has to
%   come \emph{after} the above \cmd{\AtBeginDocument} code which opens
%   the script file for writing, and \emph{before} the later
%   \cmd{\AtEndDocument} code (below) which closes it.
%
%   The |\if@cref@switched@language| flag is set when a \package{babel}
%   language switching command is called. It is checked by
%   \cmd{\cref@writelanguagerules} when writing substitution rules.

% After processing the document body, we re-read in the temporary script
% file, and write it out again to the final |sed| script file, escaping
% regexp special characters in the process. The escaping is carried out
% by turning the regexp special characters into active characters, and
% defining them to expand to their escaped form. This involves a lot of
% juggling of catcodes and lccodes!
%
% Both \cmd{\DeclareOption} and \cmd{\AtEndDocument} store their
% arguments in token lists, so all the following \TeX{} code is already
% tokenised long before it is expanded and evaluated. Thus there is no
% (easy) way to change the catcodes of the characters appearing here
% before they are tokenised. In one way this is convenient: the catcode
% changes we make don't ``take'' until evaluated, so we can continue to
% use the standard \TeX{} characters (\textbackslash, \{, \} etc.) even
% after the lines containing the catcode commands. But in another, more
% significant, way, it is very inconvenient: it makes it difficult to
% define the regexp special characters as active characters, since it's
% impossible to directly create tokens with the correct char- and
% catcodes.
%
% We get around this by creating the unusual charcode/catcode
% combinations using the \cmd{\lowercase} trick (\cmd{\lowercase} changes
% the charcodes of all characters in its argument to their lccodes, but
% \emph{leaves their catcodes alone}). That way, the argument of
% \cmd{\AtEndDocument} is tokenised correctly, and when it comes to be
% expanded and evaluated, the \cmd{\lowercase} commands create tokens
% with the correct char- and catcodes.

%   To make use of all the \option{poorman} infrastructure defined above,
%   we must redefine the \package{cleveref} referencing commands
%   themselves. There are two parts to this: at the very top layer of the
%   cross-referencing macro stack, we redefine the user-level commands to
%   first initialise |\cref@poorman@text| to the empty string, then
%   typeset the reference as usual, and finally write a substitution
%   rule to the |sed| script containing whatever has been accumulated in
%   |\cref@poorman@text|. At the very lowest layer of the macro stack, we
%   redefine the macros that actually typeset the various parts of the
%   references to additionally add a copy of whatever they typeset to
%   |\cref@poorman@text|.
%
%   We first redefine the user-level referencing commands so that they
%   write a substitution rule for the reference to the script, as well as
%   typesetting the reference itself. Most of the redefinitions differ
%   slightly depending on whether \package{hyperref} is loaded.

%
% FIXME: We only resort to this because |\string\#1| doesn't work. But

% Any contributions of translations for missing languages are most

% \begin{macro}{\cref@addlanguagedefs}
%   Utility macro to add code to \cmd{\extras}\meta{language} or

%   or \package{polyglossia} are loaded.
%    \begin{macrocode}

      \fi}{}}}%
%    \end{macrocode}
% \end{macro}
%
%
% Passing a language option to \package{cleveref} defines the
% cross-reference names and conjunctions as appropriate for that
% language. We can't make the definitions straight away, since they would
% prevent the automatic definition of the other capitalisation variant
% from working if the user chooses to change a default definition in the
% preamble, so we postpone them until the beginning of the document.
% However, if each language option were to simply define any formats that
% aren't already defined by the end of the preamble, the \emph{first}
% language option would override all the others. Unfortunately, the
% convention in \LaTeX{} and \package{babel} is for the \emph{last}
% language option to take precedence. So we instead use the
% \cmd{\crefname@preamble} command to save the definitions in
% |\cref@|\meta{type}|@name@preamble| etc., and after all the language
% options have been processed, use the contents of these to set the
% default definitions for any undefined formats.
%
% For \package{babel} support, we add the appropriate redefinitions to
% the\linebreak[4] |\extras|\meta{language} macro, which is called by
% \package{babel}'s \cmd{\selectlanguage} et al.\ commands.  The main
% language (the last one listed in the options) is set up by an automatic
% call to \cmd{\selectlanguage} at the beginning of the document, which
% would clobber any redefinitions made by the user in the preamble. To
% avoid this, we postpone adding the redefinitions to
% |\extras|\meta{language} until the beginning of the document. Since
% \package{cleveref} must always be loaded \emph{after} \package{babel},
% the redefinitions won't be added to |\extras|\meta{language} until
% \emph{after} \package{babel} has already called \cmd{\selectlanguage}
% for the main language. Thus the redefinitions will only be in effect
% when \cmd{\selectlanguage} is called explicitly within the
% document. (The definitions for the main language are taken care of by
% the language options passed to \package{cleveref}, independently of
% \package{babel}.)
%
% Note that we define both capitalisation variants explicitly throughout,
% rather than relying on the automatic definition of the other variant,
% in order to make the code produced by the poor man's |sed| script
% slightly cleaner.

%   If \LaTeX{} can find a \file{cleveref.cfg} file in its search path,

%   \file{cleveref.cfg} is to make it easy for authors to customise the
%   cross-reference formats for all their documents, without having to
%   manually include the definitions in every document preamble. In order
%   for these customisations to override the default formats, we input
%   \file{cleveref.cfg} right at the end, after the rest of
%   \package{cleveref} has loaded.
