-%% mpmulti.sty                                     09 Sep 2002
-%%------------------------------------------------------------
-%% History:
-%%   Initial version                               14 Apr 2000
-%%   Introduced keyword parameters                 12 Jun 2000
-%%   Introduced new parameters (start,format), changed the
-%%     global code to take several file counting strings (eg
-%%     bla-*.mps, foo-*.jpg, etc.), added compatibility with
-%%     \graphicspath (Jean-Christophe Dubacq)      06 Dec 2001
-%%   Generalized the format option, added the end
-%%   handling and documented extended features in here
-%%                                                 09 Sep 2002
-%%
-%% Purpose:
-%%     include multiple metapost pictures and overlay them,
-%%     inserting a transition effect between them
-%%
-%% Synopsis:
-%%
-%% \multiinclude[pause=transitioncommand,
-%%               graphics={option for includegraphics},
-%%               format=filenameformat,
-%%               start=number,
-%%               end=number]{basefilename}
-%%
-%%     Include all metapost generated graphics found in
-%%     files with the basename "filename", which
-%%     have a number attached or in the extension.
-%%     Insert the transitioncommand between the files (defaults
-%%     to \pause).
-%%     Further options allow to specify additional specifications
-%%     for includegraphics, can change the number to start with
-%%     (default 0) or the number to end with (default 1000000).
-%%     By default the filenames are as created by mpost in the format
-%%     "filename.n", where "n" represents the number.
-%%     The option format with the values like "mps", "png" or "jpg" this
-%%     can be changed to "filename-n.format", e.g. "example-0.mps"
-%%     instead of "example.0".
-%%     Complaints are only written, if the first file is not found.
-%%     Otherwise including will silently stop.
-%%
-%% Requires:
-%%     pause.sty for definitions of transition commands.
-%%     The keyval package for options processing.

-%% texpause.sty       Version 1.2                     10 Feb 2000
-%%---------------------------------------------------------------
-%% This is a quick hack to enable repeated pages with incremental
-%% contents e.g. for displaying slides uncovering step by step.
-%%
-%% The initial version (numbered 1.0) was written 07 May 99.
-%% Version 1.1 was created 25 May 99 and fixed a naming problem.
-%% Version 1.2 removed test for \pdfoutput on 10 Feb 2000
-%%
-%% Possible extensions: make the page numbering optional (maybe using
-%% subnumbering)
-%% Make action optional (for printed versions via pdf).
-%%
-%% Plan of attack (should work with TeX and LaTeX):
-%% - Get some ressources, i.e. one counter, one token register and one
-%%   box.
-%% - When activated save the current page count in the counter and the
-%%   output routine in the token register.
-%% - Setup a new output routine, which saves away a copy of the
-%%   current page.
-%% - Trigger this output routine to save the cumulated page contents.
-%% - Restore the former output routine and run it with the restored
-%%   saved contents.
-%% - Reset the page count and reinsert the contents once again,
-%%   removing the last glue item on the page.
