+The filemod Package
+~~~~~~~~~~~~~~~~~~~
+Copyright (C) Martin Scharrer <martin@scharrer-online.de>
+Version v1.0 -- 2011/03/23
+
+This package provides macros to read and compare the modification dates
+of files. These files can be .tex files, images or other files as long as they can be
+found by the LaTeX compiler. It uses the \pdffilemoddate primitive of pdfLaTeX
+to receive the file modification date as PDF date string, parses it and returns
+the value to the user. This package will also work for DVI output with recent
+versions of the LaTeX compiler which uses pdfLTEX in DVI mode. The functionality
+is provided by purely expandable macros or by faster but non-expandable ones.
+
+Examples:
+ % Prints file modification date and time of main file
+ \filemodprint{\jobname}
+
+ % Include newest of a set of files:
+ \input{\filemodNewest{{file1}{file2}{file3}}}

+% \section{Introduction}
+% This package provides several macros to read and compare the modification dates of files.
+% The same functionality is provided by two groups of macros:
+% The macros of the first group all start with a lower case letter and are fully expandable.
+% This means they can be used in places where a string must be provided, like in `|\input` or `|\includegraphics`.
+% Because assignments are not expandable some of these macros, like the ones for comparisons, need to reread and re-parse the
+% file modification dates if they are required in more than one place inside the macro.
+%
+% The macros of the second group all start with a upper case letter and are not expandable because assignments are used internally.
+% However, this allows techniques which speed up the processing of these macros, making this macros faster than the expandable counterparts.
+% If expandability is not required these macros should be preferred.
+%
+%
+% \section{Usage}
+% The following macros are provided by this package:
+%
+% \subsection{Print File Modification Date and Time}
+% The following macros can be used to print (i.e.\ typeset) the file modification date and time of files in the document.
+% The \Macro\formatdate and \Macro\formattime macros of the \pkg{datetime}\footnote{CTAN: \url{http://www.ctan.org/pkg/datetime}} can be used in addition to format the dates and times
+% in a language specific format.
+% See also the \pkg{getfiledate}\footnote{CTAN: \url{http://www.ctan.org/pkg/getfiledate}} package which also prints file modification dates including adding fancy frames around it.
+%
+% \DescribeMacro{\filemodprint}{<\/filename>}
+% Prints the file modifications date and time using `|\filemodparse` and `|\thefilemod`.
+%
+%
+% \DescribeMacro{\filemodprintdate}{<\/filename>}
+% Prints the file modifications date using `|\filemodparse` and `|\thefilemoddate`.
+%
+%
+% \DescribeMacro{\filemodprinttime}{<\/filename>}
+% Prints the file modifications time using `|\filemodparse` and `|\thefilemodtime`.
+%
+%
+% \DescribeMacro{\thefilemod}
+% Reads the date and time as seven arguments and typesets it. This macro can be redefined to a custom format.\\
+% By default it simple uses `|\thefilemoddate` and `|\thefilemodtime` separated by `|\filemodsep` (a space by default):
+% \enquote{\filemodprint{\jobname.dtx}}
+%
+%
+% \DescribeMacro{\thefilemoddate}
+% Receives the date as three arguments YYYY, MM and DD and typesets it. This macro can be redefined to a custom format.\\
+% Default format: \enquote{\filemodprintdate{\jobname.dtx}}
+%
+% It could be redefined to use the `|\formatdate` macro of the \pkg{datetime}:\\
+% |\renewcommand*{\thefilemoddate}[3]{\formatdate{#3}{#2}{#1}}|
+%
+%
+% \DescribeMacro{\thefilemodtime}
+% Receives the time and timezone as four arguments HH, mm, SS and TZ and typesets it. This macro can be redefined to a custom format.\\
+% Default format: \enquote{\filemodprinttime{\jobname.dtx}}
+%
+% It could be redefined to use the `|\formattime` macro of the \pkg{datetime}:\\
+% |\renewcommand*{\thefilemodtime}[4]{\formattime{#1}{#2}{#3}}|
+%
+%
+%
+%
+% \subsection{Get File Modification Date and Time as Number}
+% The following macros return both the file modification date and time as an integer number which is in the valid range for \TeX.
+% They can be used for numerical operations and are used internally by the comparison macros.
+%
+% \DescribeMacro{\filemodnumdate}{<\/filename>}
+% Expands to an integer of the form |YYYYMMDD| which can be used for numeric comparisons like `|\ifnum`.
+% This macros uses `|\filemodparse` and `|\filemodnotexists` will be used if the file does not exist.
+%
+% \DescribeMacro{\filemodnumtime}{<\/filename>}
+% Expands to an integer of the form |HHmmSS| which can be used for numeric comparisons like `|\ifnum`.
+% This macros uses `|\filemodparse` and `|\filemodnotexists` will be used if the file does not exist.
+%
+% \DescribeMacro{\filemodNumdate}{<\/filename>}
+% Expands to an integer of the form |YYYYMMDD| which can be used for numeric comparisons like `|\ifnum`.
+% Parses the file modification date by itself and will return |00000000| if the file does not exist.
+%
+% \DescribeMacro{\filemodNumtime}{<\/filename>}
+% Expands to an integer of the form |HHmmSS| which can be used for numeric comparisons like `|\ifnum`.
+% Parses the file modification date by itself and will return |000000| if the file does not exist.
+%
+%
+% \DescribeMacro{\Filemodgetnum}{<\/filename>}
+% Stores the file modification date and time as numbers (|YYYYMMDD| and |HHmmSS|) as well the timezone string
+% into the macros `|\filemoddate`, `|\filemodtime` and `|\filemodtz`.
+%
+%
+%
+% \subsection{Compare File Modification Date/Time}
+% The following macros allow the comparison of the file modification date/time of two files.
+%
+% \DescribeMacro{\filemodcmp}[<num>]{<\/filename 1>}{<\/filename 2>}{<clause 1>}{<clause 2>}!\optional!{<clause 3>}
+% This macro compares the file modification date and time of the two given files and expands to the clause of the
+% newest file. An numerical optional argument can be given to determine the outcome if both files have the exact same
+% modification date/time (or both do not exists). If `<num>` is 0, no clause will be expanded, i.e.\ the macro expands
+% to an empty text. If `<num>` is 1 (default) or 2 the macro expands to the corresponding clause.
+% However if `<num>` is 3, the macro will await a third clause and expands to it if both files modification dates are equal.
+%
+% This macro is fully expandable even when the optional argument is used. However, `<\/filename 1>` must not be equal to "[".
+%
+%
+% \DescribeMacro{\filemodCmp}{<\/filename 1>}{<\/filename 2>}{<clause 1>}{<clause 2>}
+% This is a simpler and therefore faster version of `|\filemodcmp`. It is fully expandable, does not take any optional
+% arguments and will always expand to the first clause if both file modification dates are equal (or both files do not exist).
+% The `|\filemodNumdate` and `|\filemodNumtime` macros are used in the comparison.
+% These three macros are also provided by the sub-package \pkg{filemod-expmin}.
+%
+%
+% \DescribeMacro{\Filemodcmp}[<num>]{<\/filename 1>}{<\/filename 2>}{<clause 1>}{<clause 2>}!\optional!{<clause 3>}
+% This macro provides the same functionality as `|\filemodcmp`.
+% It is not expandable but will be processed faster. The optional
+% argument is processed like normally.
+%
+% \DescribeMacro{\FilemodCmp}[<num>]{<\/filename 1>}{<\/filename 2>}
+% This macro will compare the two file modification dates like `|\Filemodcmp` and `|\filemodcmp` but does not take
+% the possible clauses as arguments, instead it stores the result into the expandable macro `|\filemodcmpresult`
+% which then takes `{<clause~1>}!\linebreak[3]!{<clause~2>}` (and also `{<clause~3>}` if `<num>` was 3) as arguments and expand to the one
+% corresponding to the newest file.
+% This set of macros gives the user the speed benefit of `|\Filemodcmp` while still be able to use the result in an expandable context.
+%
+%
+% \DescribeMacro{\filemodoptdefault}
+% Holds the default number (i.e.\ 1) for the optional argument of the previous and following macros.
+% This macro can be redefined with a number or a numeric expression valid for |\ifcase|. It should not contain any
+% trailing spaces. Note that some commands only accept 1 or 2 as valid optional argument.
+%
+%
+%
+% \subsection{Return Newest or Oldest File from a List}
+% The following macros return the newest or oldest file.
+% Note that the optional arguments of the following macros should only be either 1 or 2.
+% If no optional argument is provided the value of `|\filemodoptdefault` is used.
+%
+% \DescribeMacro{\filemodnewest}[<num>]{<\/filename 1>}{<\/filename 2>}
+% Expands the filename of the newest given file or filename `<num>` if both file modification dates are identical.
+% The catcode of the filenames is not changed.
+%
+% \DescribeMacro{\filemodoldest}[<num>]{<\/filename 1>}{<\/filename 2>}
+% Expands the filename of the oldest given file or filename `<num>` if both file modification dates are identical.
+% The catcode of the filenames is not changed.
+%
+%
+% \DescribeMacro{\filemodNewest}[<num>]{{<\/filename 1>}{<\/filename 2>}'...'{<\/filename n>}}
+% Expands the filename of the newest given file.
+% The filename will have catcode 12 except in the case when only one filename was given which is returned unchanged.
+% The files are compared in pairs of two in the given order (i.e.\ first 1 and 2 and the result with 3 etc.)
+% The optional argument `<num>` can be used to indicate which filename should be used if both file modification dates are identical.
+%
+%
+% \DescribeMacro{\filemodOldest}[<num>]{{<\/filename 1>}{<\/filename 2>}'...'{<\/filename n>}}
+% Expands the filename of the oldest given file.
+% The filename will have catcode 12 except in the case when only one filename was given which is returned unchanged.
+% The files are compared in pairs of two in the given order (i.e.\ first 1 and 2 and the result with 3 etc.)
+% The optional argument `<num>` can be used to indicate which filename should be used if both file modification dates are identical.
+%
+%
+%
+% \DescribeMacro{\Filemodnewest}[<num>]{<\/filename 1>}{<\/filename 2>}
+% Same as `|\filemodnewest` just not expandable but faster.
+% Stores the newer of the two file names in `|\filemodresultfile`. Its file modification date and time is stored
+% in `|\filemodresultdate` and `|\filemodresulttime`.
+% The catcode of the filenames is not changed.
+%
+%
+% \DescribeMacro{\Filemodoldest}[<num>]{<\/filename 1>}{<\/filename 2>}
+% Same as `|\filemodoldest` just not expandable but faster.
+% Stores the older of the two file names in `|\filemodresultfile`. Its file modification date and time is stored
+% in `|\filemodresultdate` and `|\filemodresulttime`.
+% The catcode of the filenames is not changed.
+%
+%
+% \DescribeMacro{\FilemodNewest}[<num>]{{<\/filename 1>}{<\/filename 2>}'...'{<\/filename n>}}
+% Same as `|\filemodNewest` just not expandable but faster.
+% Stores the newest of the given file names in `|\filemodresultfile`. Its file modification date and time is stored
+% in `|\filemodresultdate` and `|\filemodresulttime`.
+% The catcode of the filenames is not changed.
+%
+%
+% \DescribeMacro{\FilemodOldest}[<num>]{{<\/filename 1>}{<\/filename 2>}'...'{<\/filename n>}}
+% Same as `|\filemodOldest` just not expandable but faster.
+% Stores the oldest of the given file names in `|\filemodresultfile`. Its file modification date and time is stored
+% in `|\filemodresultdate` and `|\filemodresulttime`.
+% The catcode of the filenames is not changed.
+%
+%
+%
+%
+% \subsection{Parsing of the file modification date}
+% The format returned by the |\pdffilemoddate| primitive is \enquote{\texttt{D:}} followed by a number in the format \enquote{\texttt{YYYYMMDDHHmmSST}} which needs to be parsed before
+% it is useful. The letters have the following meaning: \texttt{Y} = year, \texttt{M} = month, \texttt{D} = day, \texttt{H} = hour, \texttt{mm} = minutes, \texttt{S} = seconds, \texttt{T} or \texttt{TZ} = timezone string. The number of letters indicates the length except for the timezone which is of variable length.
+% An example is \enquote{\texttt{\pdffilemoddate{\jobname.dtx}}} which is the file modification date of the source file of this manual.
+% Unfortunately this number is to large for TeX to be taken as an integer for numerical comparisons, so it is broken into two numbers (\texttt{YYYYMMDD} and \texttt{HHmmSS}) which are compared
+% in multiple steps.
+%
+% \DescribeMacro{\filemodparse}{<macro>}{<\/filename>}
+% Parses the file modification datetime of the given file and passes the result to the given macro.
+% The macro will receive seven arguments:
+% \begin{quote}
+% `<macro>{<YYYY>}{<MM>}{<DD>}{<HH>}{<mm>}{<SS>}{<TZ>}`
+% \end{quote}
+% i.e.\ year, month, day, hour, minutes, seconds and the timezone as signed offset
+% or `Z` (catcode 12).
+%
+%
+% \DescribeMacro{\filemodnotexists}{<macro>}
+% This macro will be called by `|\filemodparse` with the original given macro when the given file does not exists. By default
+% it contains all zeros except `Z` (catcode 12) as timezone:
+%
+% \begin{quote}
+% `!\#1!{0000}{00}{00}{00}{00}{00}{Z}`
+% \end{quote}
+% The user can redefine this macro to a different content, e.g.\ to a different fall-back value or to display a warning.
+% Note if this macro contains non-expandable code the macros which uses it aren't expandable anymore.
+%
+%
+%
+% \subsection{Auxiliary Macros}
+%
+% \DescribeMacro{\filemodZ}
+% Defined to "Z" with catcode 12 as it is returned as timezone.
+% This might be useful for comparisons or custom definitions.
+%
+% \DescribeMacro{\filemodz}
+% Let (`|\let`) to "Z" with catcode 12 as it is returned as timezone.
+% This might be useful for comparisons or custom definitions.

+% \subsubsection{Optional argument handler}
+%
+% \begin{macro}{\filemod@opt}[3]{Macro to read optional argument when present}{Next macro which receives default optional argument as first normal argument}{\texttt{[} or first mandatory argument}
+% This macro checks if an optional argument is present. Here |#1| and |#2| are handlers and |#3| is the first balanced text which followed the macro, i.e.\ either "[" or the first
+% mandatory argument.
+% The |\ifx| compares "[" and the first token of |#3|. There are three possible cases:
+% \begin{enumerate}
+% \item If they do not match everything until and including |\else| is skipped.
+% Then |\remove@to@nnil@exec| is expanded which removes the following |\@nnil|. This leaves |\empty| and the rest of the \emph{false} clause.
+% The |\fi| is removed using |\expandafter| and the trailing |{#3}| is read by |#2| as normal argument.
+% \item If |#3| is exactly "[" the |\ifx[#3| part is removed by \TeX. The |\remove@to@nnil@exec| removes the |\@nnil| and the |\remove@to@nnil| because there was nothing before |\@nnil|.
+% Therefore |\expandafter#1| is executed which triggers |\else| which removes everything up to and including |\fi|.
+% Then the optional argument handler |#1| is expanded which receives the "[" as "{[}" which is then gobbled.
+% \item The |#3| starts with "[" but contains more material, i.e.\ was original a mandatory argument. Then |\ifx| expands to the \emph{true} clause and removes
+% the first token of |#3|. The |\remove@to@nnil@exec| gobbles the rest of |#3| but reads and reinserts |\remove@to@nnil| which gobbles everything to the next |\@nnil|
+% after |\else| and therefore jumps to the \emph{false} clause. This clause is executed like normal, i.e.\ |#2| is called with the default optional argument and |{#3}| as second argument.
+% \end{enumerate}
