 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.

+PDF or DVI mode) or Lua(La)TeX is used. Xe(La)TeX is not supported because it
+does not provide \pdffilemoddate.

+    pdflatex filemod.dtx
+    pdflatex filemod.dtx
+    pdflatex filemod.dtx
+
+Copy the files to the following directories which must be created beforehand.

+copy it using a graphics interface.
+
+    cp filemod*.sty ${TEXMF}/tex/latex/filemod/

+
+The source can be installed by:
+    cp filemod.dtx  ${TEXMF}/source/latex/filemod/
+
+The TEXMF is /usr/local/texlive/2010/texmf-dist, ${HOME}/texmf or similar.

 % \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:
+% 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.

-% 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

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.

-% 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
