-% \begin{abstract}
-%   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 pdf\LaTeX\ to receive the file modification date as PDF date string, parses it and returns the value to the user.
-%   The functionality is provided by purely expandable macros or by faster but non-expandable ones.
-%
-%   This package will work with \LaTeX{} and plain \eTeX{} as long pdf\LaTeXTeX{} (in PDF or DVI mode) or Lua\LaTeXTeX{}
-%   is used. \XeTeX{} is not supported because it does not provide |\pdffilemoddate|.

-% \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`.  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}
-% This package can be loaded with \LaTeX{} using |\usepackage{filemod}| as usual.
-% With plain \eTeX{} it can be loaded using |\input filemod|.
-% Some required internal \LaTeX{} macros (like |\@gobble|, |\@firstofone|, etc.) are then defined.
-%
-% A minimal set of expandable macros for the comparison of file modification dates is provided by the sub-package
-% \pkg{filemod-expmin}. It is useful for other packages which need this functionality but don't like to load the whole package.
-% It can be loaded using |\usepackage{filemod-expmin}| (or |\RequirePackage|) or |\input filemod-expmin|, respectively.
-%
-%
-% \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}}|
-%
-%
-% \DescribeMacro{\Filemodtoday}{<\/filename>}
-% Prints the file modification date of the given file in the current format of \Macro\today.
-% For this the compiler date is set locally to the file modification date and then \Macro\today is used to print that date.
-% This takes advantages of any localised definition provided by the \pkg{babel} package or other packages.
-%
-% \DescribeMacro{\FilemodToday}{<\/filename>}
-% Similar to \Macro\FilemodToday but also prints the full file modification date/time using the
-% \Macro\thefilemod format macro.
-% For this the \Macro\thefilemoddate macro is changed locally to use \Macro\today with the file modification date.
-%
-%
-% \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.

-%
-% \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.
