+% \section{Introduction}
+%
+% When ``clever'' is used in the name of a computer program, it
+% usually signifies that the programmer is overly smug! Or, to take a
+% more charitable attitude, that the programmer is pleased with the
+% sophisticated processing that he has managed to encapsulate in code,
+% relieving the user of some complicated by tedious task. On the other
+% hand, at the heart of the \LaTeX philosophy is the idea that it is
+% clever to delegate as much of the typesetting as possible to the
+% computer, in order to achieve a beautiful, but above all consistent,
+% visual appearance.
+%
+% Both these points of view are valid with respect to the
+% \package{cleveref} package. It's goals are two-fold: to use the
+% information that \LaTeX inherently has about labels as
+% intelligently as possible in order to type-set references to them
+% (clever processing); and to enable you to produce an attractive,
+% consistent formatting of 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
+% facility by allowing references to be formatted automatically
+% according to the type of object they refer to (chapter, section,
+% equation, theorem, etc.). It can also automatically format
+% references to multiple labels.
+%
+% In standard \LaTeX, you have almost certainly found yourself
+% writing things like |Eq.~(\ref{eq1})| and |Theorem~\ref{thm1}| over
+% and over again. This isn't just tedious. What happens if you later
+% decide you want equation references to be typeset as
+% |Equation~\ref{eq1}| instead? What happens if you decide to change
+% the theorem labelled |thm1| into a lemma? You have to search
+% through the entire \LaTeX source of your document, modifying all
+% references to equations, or changing all references to |thm1|.
+%
+% \package{cleveref} allows you to define the format for references
+% once-and-for-all in the preamble of your document. If you later
+% decide to change the typesetting of equation references, you only
+% have to change one preamble definition. If you later decide to
+% change a theorem into a lemma, you don't need to change any
+% references at all, because \package{cleveref} will automatically
+% typeset references to it using the appropriate formatting. This
+% makes it far easier to typeset references uniformly across your
+% whole document, as well as saving repetitively typing the same text
+% for each and every reference.
+%
+% A number of other packages provide similar features, most notably
+% \package{varioref}, \package{fancyref} and (for theorem-like
+% environments) \package{ntheorem} (with the \option{thref}
+% option). However, all have certain deficiencies which
+% \package{cleveref} attempts to overcome.
+%
+% The \package{fancyref} package doesn't automatically determine the
+% type of object 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 be inconvenient. For example, if you change a
+% theorem into a lemma, you have to change the label name, and
+% therefore also all references to it. So you are back to searching
+% and replacing through the entire document.
+%
+% The enhanced referencing feature provided by the \package{varioref}
+% package decides how to format references when the label is
+% \emph{defined}, rather than when it is \emph{referenced}. Most of
+% the time, this isn't a problem. But it makes it impossible to format
+% references differently according the context in which they are
+% referenced, which can sometimes be very useful. For example, if you
+% want references at the beginning of a sentence formatted any other
+% way than by capitalising the first letter of the reference text, it
+% is impossible using \package{varioref}. Perhaps even more
+% significantly, it makes it impossible to typeset multiple references
+% automatically; you are back typesetting
+% |Eqs.~(\ref{eq1}) and~(\ref{eq2})| or
+% |Eqs.~(\ref{eq1})--(\ref{eq3})| by hand.
+%
+% The \package{ntheorem} package (with the \option{thref} option) does
+% things right\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 |\label| commands telling it the label
+% type. \package{cleveref} essentially extends the \package{ntheorem}
+% theorem referencing feature to work for all objects. (Although the
+% implementation details differ, and \package{cleveref} can be used
+% independently of \package{ntheorem}.) \package{cleveref} provides a
+% number extra features too, such as multiple references, automatic
+% collapsing of reference ranges, and control over the placement of
+% hyper-links.
+%
+%
+%
+% \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}).
+%
+%
+% \subsection{Typesetting References}
+%
+% \DescribeMacro\cref
+% To automatically typeset a reference according to the type of object
+% referred to, simply refer to it using |\cref{|\meta{label}|}|.
+% \package{cleveref} imposes just one restriction on the names of
+% labels: they are no longer allowed to contain commas ``,''. These
+% can instead be used to typeset multiple references (see below).
+%
+% \DescribeMacro\Cref
+% As it is very difficult for \LaTeX to determine whether a
+% reference appears at the beginning of a sentence or not, a
+% capitalised version exists: |\Cref{|\meta{label}|}|. By default,
+% this typesets the reference with the first letter capitalised,
+% though the formatting of the |\cref| and |\Cref| forms can be
+% customised independently (see \cref{sec:customising}).
+%
+% \DescribeMacro\ref
+% \package{cleveref} does \emph{not} modify the standard |\ref|
+% command\footnote{This is not quite true. The original \cmd{\ref}
+% command no longer works when \package{cleveref} is loaded, so
+% \package{cleveref} redefines it to recover the correct
+% behaviour.}, so you can still use it to typeset the formatted
+% label counter alone, without any additional text or formatting. If
+% you would like to use \package{cleveref}'s enhanced features, but
+% want to continue to use |\ref| for referencing, simply redefine the
+% |\ref| command in your document's preamble, thus:
+% \begin{quote}
+% |\renewcommand{\ref}{\cref}|
+% \end{quote}
+% Similarly, if you decide you would like all references capitalised,
+% you can redefine the |\cref| command:
+% \begin{quote}
+% |\renewcommand{\cref}{\Cref}|
+% \end{quote}
+%
+% \DescribeMacro\crefrange
+% \DescribeMacro\Crefrange
+% To typeset a reference range, e.g. |Eqs.~(1.1)--(1.5)|, use
+% |\crefrange| or |\Crefrange| (depending on the capitalisation you
+% require), which take the beginning and end of the range as
+% arguments:
+% \begin{quote}
+% |\crefrange{|\meta{label1}|}{|\meta{label2}|}|
+% \end{quote}
+%
+% \DescribeMacro\cref
+% \DescribeMacro\Cref
+% To typeset multiple references, simply list the lables inside the
+% |\cref| or |\Cref| command, separated by commas (you are not allowed
+% to use commas in label names when using \package{cleveref}):
+% \begin{quote}
+% |\cref{|\meta{label1}|,|\meta{label2}|,|\meta{label3}|,...}|
+% \end{quote}
+% The references will be typeset in the order in which they appear in
+% the list, and sequences of consecutive references will be collapsed
+% into a reference range. It is up to you to put the labels in the
+% order you require. This is especially significant if the labels
+% refer to different types of object, or to consecutive sequences of
+% labels. For example, if |eq*| are equation labels, and |thm*| are
+% theorem labels,
+% \begin{quote}
+% |\cref{eq1,eq2,eq3,thm1,thm2}|
+% \end{quote}
+% will be typeset as
+% \begin{quote}
+% Eqs.~(1)--(3), and Theorems~1 and~2
+% \end{quote}
+% whereas
+% \begin{quote}
+% |\cref{eq1,eq2,thm1,thm2,eq3}|
+% \end{quote}
+% will be typeset as
+% \begin{quote}
+% Eqs.~(1) and~(2), Theorems~1 and~2, and Eq.~(3)
+% \end{quote}
+%
+%
+% \subsection{Customising the Reference Formats}
+% \label{sec:customising}
+%
+% \subsubsection{Single References}
+% \label{sec:ref_format}
+% The \package{cleveref} package allows you to take full control of
+% the typesetting of references. Defaults appropriate for English
+% documents are provided for the standard reference types. But if you
+% don't like them, or are writing in a different language, or you are
+% using an environment for which no default format is defined, you
+% will need to define your own.
+%
+% If \package{cleveref} encounters a reference to a type it does not
+% know, it will produce a ``reference type undefined'' warning, and
+% typeset the reference as
+% \begin{quote}
+% {\bf ??}~|\ref{|\meta{label}|}|
+% \end{quote}
+% i.e.\ it will typeset the reference as the label counter preceded by
+% a double question mark. References to undefined labels still produce
+% a ``reference undefined'' warning and are typeset as a double
+% question mark, as usual.
+%
+% \DescribeMacro\crefformat
+% \DescribeMacro\Crefformat
+% Reference formats for \emph{single} 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 reference type, and the formatting code:
+% \begin{quote}
+% |\crefformat{|\meta{type}|}{|\meta{format}|}|\\
+% |\Crefformat{|\meta{type}|}{|\meta{format}|}|
+% \end{quote}
+%
+% 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 whe |\Crefformat| is
+% called, if will define the |\Crefformat| to produce a lower-case
+% version of |\Crefformat|, using |\MakeLowercase|. Obviously, this
+% will only work properly if the formats have a letter at the
+% start. If the first letter is a special construct, such as an
+% accented character, you will need to surround everything whose case
+% should be changed by braces. If the first thing in the format is not
+% a letter (e.g.\ if it is a \LaTeX command, or a hyper-link
+% argument, see below), you will get strange and fatal errors when
+% processing the document.
+%
+% The reference \meta{type} is usually the name of the counter for the
+% environment (equation, chapter, section, etc.). Currently, the only
+% exception is theorem-like environments when the \package{ntheorem}
+% package is loaded, for which \meta{type} should instead be the
+% environment name (lemma, corollary, definition, etc.). This is
+% because \package{ntheorem} allows different theorem-like
+% environments to use a common counter.
+%
+% 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.\
+% |\theequation|). The other two are used to mark the beginning and
+% end of the part of the reference that should form the hyper-link
+% when the \package{hyperref} package is used (see
+% \cref{sec:other_packages}). The hyper-link arguments |#2| and |#3|
+% \emph{must} appear in that order. Leaving them out completely will
+% not cause an error, but will mean that no hyper-link will be created
+% when \package{hyperref} is used.
+%
+% 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 brackets) forming the hyper-links.
+% Note that the hyper-link arguments are \emph{not} letters, so if you
+% want to make the ``Eq.'' part of the hyper-link by putting |#2| at
+% the start of the formatting code, you will have to define both
+% capitalisation variants independently:
+% \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|. You do not have to define it if
+% you don't plan to use any reference ranges, i.e. you never use the
+% |\crefrange| and |\Crefrange| commands, and you never use multiple
+% references (see \cref{sec:multiple_ref_format}). However, you will
+% get ``reference format undefined'' errors if you later change your
+% mind and forget to define the format. Like |\creformat| and
+% |\Crefformat|, the commands take two arguments: the reference type,
+% and the formatting code.
+% \begin{quote}
+% |\crefrangeformat{|\meta{type}|}{|\meta{format}|}|\\
+% |\Crefrangeformat{|\meta{type}|}{|\meta{format}|}|
+% \end{quote}
+% The same comments apply: the \meta{type} is usually the name of the
+% counter, except for theorem-like environments, and if the
+% corresponding 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
+% hyper-link for the first reference (|#1|), and the final two (|#5|
+% and |#6|) mark the beginning and end of the second reference's
+% hyper-link.
+%
+% As an example,
+% \begin{quote}
+% |\crefrangeformat{equation}{Eqs.~(#3#1#4)--(#5#2#6)}|
+% \end{quote}
+% will typeset equation reference ranges as
+% \begin{quote}
+% Eqs.~(\meta{counter1})--(\meta{counter2})
+% \end{quote}
+% with the counters (excluding the brackets) forming the hyper-links.
+%
+%
+% \subsubsection{Multiple References}
+% \label{sec:multiple_ref_format}
+% \DescribeMacro\crefmultiformat
+% \DescribeMacro\Crefmultiformat
+% \DescribeMacro\crefrangemultiformat
+% \DescribeMacro\Crefrangemultiformat
+% The format for multiple references is defined by |\crefmultiformat|
+% and\linebreak[4] |\Crefmultiformat|, and that of reference ranges
+% within multiple references by |\crefrangemultiformat| and
+% |\Crefrangemultiformat|. If you don't use any multiple references
+% for a particular reference type, you are not obliged to define the
+% multi-formats. However, you will get ``reference format undefined''
+% errors if you later decide to use a multiple reference without
+% ensuring the multi-formats are defined. You will also need to define
+% \emph{all} the other reference formats (see
+% \cref{sec:ref_format,sec:ref_range_format}), including the reference
+% range formats, even if you never use the |\crefrange| and
+% |\Crefrange| commands.
+%
+% The commands all take four arguments: the reference type, the format
+% for the first reference in a list, the format for the middle
+% references in a list, and the format for the last reference in a
+% list.
+% \begin{quote}
+% |\crefmultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{middle}|}{|\meta{last}|}|\\
+% |\Crefmultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{middle}|}{|\meta{last}|}|\\
+% |\crefrangemultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{middle}|}{|\meta{last}|}|\\
+% |\Crefrangemultiformat{|\meta{type}|}{|\meta{first}|}{|\meta{middle}|}{|\meta{last}|}|
+% \end{quote}
+%
+% The same considerations apply to the \meta{type} and formatting
+% arguments \meta{first}, \meta{middle} and \meta{last} as for the
+% \meta{format} argument of |\crefformat| and |\Crefformat| or
+% |\crefrangeformat| and |\Crefrangeformat|, including the meaning of
+% the arguments that should appear in the formatting code. However,
+% when the corresponding other-capitalisation variant is automatically
+% defined, only the first letter of the \meta{first} argument is
+% upper- or lower-cased.
+%
+% Be careful to get the spaces at the beginning and end of the
+% formatting code correct: the \meta{first}, \meta{middle} and
+% \meta{last} \LaTeX code is typeset one after another in a
+% multi-reference, with no space separating them. You may or may not
+% want spaces at the beginning and end of the formatting code,
+% depending on the formatting you desire. For example, with the
+% default format
+% \begin{quote}
+% |\crefmultiformat{equation}%|\\
+% |{Eqs.~(#2#1#3)}{, (#2#1#3)}{ and~(#2#1#3)}|\\
+% \end{quote}
+% the \meta{middle} arguments should \emph{not} have a space at the
+% beginning, whereas the \meta{last} arguments \emph{should} have a
+% space.
+%
+% \DescribeMacro{\crefmiddleconjunction}
+% \DescribeMacro{\creflastconjunction}
+% The |\crefmiddleconjunction| and |\creflastconjunction| commands are
+% used in between sub-lists of different types of references that
+% occur in a multiple reference. If there are two or more reference
+% types in the list, |\creflastconjunction| is used between the
+% penultimate and final group of references, whereas
+% |\crefmiddleconjunction| is used between all others. You can
+% redefine them with |\renewcommand| in the usual way:
+% \begin{quote}
+% |\renewcommand{\crefmiddleconjunction}{|\meta{conjunction}|}|\\
+% |\renewcommand{\creflastconjunction}{|\meta{conjunction}|}|
+% \end{quote}
+% For example, if |eq*|, |thm*| and |fig*| are respectively equation,
+% theorem and figure labels,
+% \begin{quote}
+% |\cref{eq1,eq2,eq3,thm1,thm2,fig1,thm3}|
+% \end{quote}
+% is typeset (assuming the default |\crefformat|s) as
+% \begin{quote}
+% Eqs.~(1)--(3)|\crefmiddleconjunction| Theorems~1\\
+% and~2|\crefmiddleconjunction| Fig.~1|\creflastconjunction|
+% Theorem~3
+% \end{quote}
+%
+%
+% \section{Interaction with Other Packages}
+% \label{sec:other_packages}
+% Since \package{cleveref} redefines many internal commands involved
+% in \LaTeX's referencing system, it can interact badly with other
+% packages that do the same. In general, \package{cleveref} should be
+% loaded \emph{last}, and the appropriate options must be supplied if
+% the \package{hyperref} and/or \package{ntheorem} packages are also
+% used. E.g.
+% \begin{quote}
+% |\usepackage{hyperref}|\\
+% |\usepackage[hyperref]{cleveref}|
+% \end{quote}
+% or
+% \begin{quote}
+% |\usepackage{ntheorem}|\\
+% |\usepackage[ntheorem]{cleveref}|
+% \end{quote}
+% or
+% \begin{quote}
+% |\usepackage{hyperref}|\\
+% |\usepackage[hyperref]{ntheorem}|\\
+% |\usepackage[hyperref,ntheorem]{cleveref}|
+% \end{quote}
+%
+% \package{varioref}'s enhanced referencing features (which you make
+% use of by via the |\labelformat| command), the \package{fancyref}
+% package, and \package{ntheorem}'s \option{thref} option are
+% incompatible with \package{cleveref}. However, since
+% \package{cleveref} implements an enhanced version of these features,
+% this is not really a problem. For example, if you have a
+% pre-existing document that uses \package{ntheorem}'s |\thref|
+% command, you can simply redefine it to call |\cref| instead:
+% \begin{quote}
+% |\renewcommand{\thref}{\cref}|
+% \end{quote}
+% Note that you can still use the other features of \package{varioref}
+% and \package{ntheorem} whilst using \package{cleveref}.
+%
+% Other packages which alter the \LaTeX referencing system are
+% unlikely to work properly with \package{cleveref}.
+%
+%
+% \section{Known Bugs}
+% \begin{itemize}
+% \item \package{cleveref} will not work properly with the standard
+% \LaTeX |eqnarray| environment. The |eqnarray| environment is
+% poorly implemented, making it somewhat difficult to get it to work
+% properly with \package{cleveref}. You're better off using the
+% \package{amsmath} replacements in any case, such as |gather|,
+% |align|, |multine| and |split|, which \emph{do} work properly with
+% \package{cleveref}. (See
+% \url{http://www.tug.org/pracjourn/2006-4/madsen/}).
+% \item \package{cleveref}'s referencing features currently may or may
+% not work properly with references to list items. (This should be
+% fixed in a future version.)
+% \item \package{cleveref} breaks \package{hyperref}'s
+% \option{backref} option, and probably also the \package{backref}
+% package when used by itself. (This should be fixed in a future
+% version.)
+% \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 collapsing of consecutive
+% references into a reference range may be incorrect.
+% \item \package{cleveref} provides no \package{babel} support.
+% \end{itemize}
+%
+%
+% \section{Future Improvements}
+% \begin{itemize}
+% \item Allow selective disabling of reference-range collapsing in
+% multiple references, e.g.\ by the addition of an extra comma
+% between the labels in the label list.
+% \item Allow reference-range collapsing to be disabled entirely via a
+% package option
+% \item Implement a ``poor-man's'' \package{cleveref}, for situations
+% in which you are able to install and use \package{cleveref}
+% locally, but annother party can not (e.g.\ when submitting the
+% \LaTeX source of a paper to a journal). When this option is set,
+% \package{cleveref} would generate a sed or awk script through
+% which the original source could be processed, generating a version
+% of the source with all the \package{cleveref} references replaced
+% by the text they would generate plus standard |\ref| commands.
+% \end{itemize}

+%
+% \section{Implementation}
+%
+% Essentially, the core of the implementation consists of causing an
+% extra piece of information -- the label ``type'' -- to be written to
+% the aux file, and defining an \cmd{\cref} command which uses this
+% extra information to typeset the reference.
+%
+% The least invasive implementation 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 cotains the typeset version of the
+% counter, now contains the additional information (in fact, we write
+% three extra pieces of information: the type, the counter value
+% itself, and the formatted version of the counter that causes the
+% label's counter to be reset, which we call the ``prefix'' from now
+% on). \cmd{\@currentlabel} eventually gets written to the aux file as
+% an argument to \cmd{\newlabel} by the usual \LaTeX
+% mechanisms. This involves less hacking to get everything else
+% working again, since very few macros other than \cmd{\ref} use this
+% particular \cmd{\newlabel} argument (nor are other packages likely
+% to, given that \package{varioref} is a required package).
+%
+%
+% \subsection{Redefinitions of \LaTeX kernel macros}
+% We store the original \cmd{\refstepcounter} in
+% \cmd{\old@refstepcounter}, then redefine \cmd{\refstepcounter} so
+% that it first calls the old version and then adds the extra
+% information to \cmd{\@currentlabel}. The new \cmd{\@refstepcounter}
+% can take an optional argument, which overrides using the counter
+% name as the ``type'' and instead uses whatever is supplied.
+% \begin{macrocode}
+\let\old@refstepcounter\refstepcounter
+\def\refstepcounter%
+ {\@ifnextchar[{\refstepcounter@optarg}{\refstepcounter@noarg}}%]
+\def\refstepcounter@noarg#1{%
+ \old@refstepcounter{#1}%
+ \reset@by{#1}{\@result}%
+ \ifx\@result\relax\def\@result{}%
+ \else\edef\@result{\csname the\@result\endcsname}\fi%
+ \protected@edef\@currentlabel{%
+ [#1][\arabic{#1}][\@result]\@currentlabel}}
+\def\refstepcounter@optarg[#1]#2{%
+ \old@refstepcounter{#2}%
+ \reset@by{#2}{\@result}%
+ \ifx\@result\relax\def\@result{}%
+ \else\edef\@result{\csname the\@result\endcsname}\fi%
+ \protected@edef\@currentlabel{%
+ [#1][\arabic{#2}][\@result]\@currentlabel}}
+% \end{macrocode}
+%
+% The standard \cmd{\ref} macro spits out whatever was in
+% \cmd{\@currentlabel} when the label was written to the aux file, but
+% this now contains the additional type information which we don't
+% want. Therefore, we redefine \cmd{\cref} to recover the original
+% behaviour. We have to defer redefinition of \cmd{\ref} till the
+% beginning of the document, in case other packages (such as
+% \package{ntheorem}) modify it after \package{cleveref} is loaded.
+% \begin{macrocode}
+\def\cref@label#1#2{\@result}
+\AtBeginDocument{%
+ \def\ref#1{%
+ \expandafter\ifx\csname r@#1\endcsname\relax%
+ \let\@result\relax%
+ \else%
+ \cref@getlabel{#1}{\@result}%
+ \fi%
+ \expandafter\@setref\csname r@#1\endcsname{\cref@label}{#1}}%
+}
+% \end{macrocode}
+%
+% \subsection{Utility Macros}
+% Define some utility macros for extracting label, type, and counter
+% information from the contents of \cmd{\@currentlabel}, as written to
+% the aux file and stored in \cmd{\r@\meta{label}} when this is re-read
+% on the next pass. Some other packages commandeer the referencing
+% system to write label information to the 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 macro \emph{will} then be fully
+% expandable, and can be used e.g.\ inside an \cmd{\edef} or
+% \cmd{\csname}\ldots\cmd{\endcsname}.
+% \begin{macrocode}

+%
+% We treate multiple references, supplied as a comma-separated list to
+% \cmd{\cref} or \cmd{\Cref}, as a stack structure. So we define some
+% utility macros for manipulating stacks (\cmd{\@nil} is used as an
+% end-of-stack delimeter).

+%
+% We need to be able to determine which counter is used to reset a
+% given counter. Usually, resets are done by sectioning counters, and
+% we assume that to be the case here. \cmd{\isinresetlist} searches
+% through one counter's reset list, stored in
+% \cmd{\cl@\meta{counter}}, to determine whether another counter
+% appears there, and sets the new conditional
+% appropriately. \cmd{\reset@by} searches through all the sectioning
+% counters' reset lists, from lowest-level (subsubsection) to highest
+% (part), checking whether the given counter is in the list, and
+% returns the first sectioning counter whose list it appears in.

+% \subsection{Reference Format Customisation Commands}
+% \cmd{\crefformat} et al.\ are user-level commands used to define the
+% format of different reference types. They simply use the supplied
+% argument(s) to define appropriately named formatting macro(s), which
+% are called by \cmd{\@setcref}. The only moderately interesting part
+% is that if the corresponding \cmd{\Crefformat} or \cmd{\crefformat}
+% variant is not already defined, they define it to be a version with
+% the first letter capitalised or lower-cased.
+% \begin{macrocode}
+\newcommand{\crefformat}[2]{\@crefformat{cref}{#1}{#2}}
+\newcommand{\Crefformat}[2]{\@crefformat{Cref}{#1}{#2}}
+\newcommand{\crefrangeformat}[2]{\@crefrangeformat{crefrange}{#1}{#2}}
+\newcommand{\Crefrangeformat}[2]{\@crefrangeformat{Crefrange}{#1}{#2}}
+\newcommand{\crefmultiformat}[4]{%
+ \@crefmultiformat{cref}{#1}{#2}{#3}{#4}}
+\newcommand{\Crefmultiformat}[4]{%
+ \@crefmultiformat{Cref}{#1}{#2}{#3}{#4}}
+\newcommand{\crefrangemultiformat}[4]{%
+ \@crefrangemultiformat{crefrange}{#1}{#2}{#3}{#4}}
+\newcommand{\Crefrangemultiformat}[4]{%
+ \@crefrangemultiformat{Crefrange}{#1}{#2}{#3}{#4}}
+% \end{macrocode}
+% The utility macros do the real work, by using the first argument
+% (``cref'', ``Cref'', ``crefrange'' or ``Crefrange'') to determine
+% how to define the corresponding command with the other
+% capitalisation.
+% \begin{macrocode}
+\def\@crefformat#1#2#3{%
+ \expandafter\def\csname #1@#2@format\endcsname##1##2##3{#3}%
