%% 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.
%%
%%
\RequirePackage{pause}
\RequirePackage{keyval}
%%
%% The command should process the optional arguments.
