+% clear copyright notice is given in the original file nor is even the
+% author indicated. The author appears to be Klaus Guntermann and the
+% license appears to be GPL, at least the whole package is distributed
+% under GPL, so I assume that also applies to the individual

+% This file does the same as the original mpmulti.sty. The only
+% differences are that a) the package pause is not loaded (it's
+% provided automatically by beamer and it should be loaded ``by hand''
+% when using ppower4) and b) a default overlay specification can be
+% given (as in \multiinclude[<+->][...]{...}), which will be the
+% argument to an actionenv that is put around each image.

+%%------------------------------------------------------------
+%% 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[defaultoverlayspecification]%
+%%              [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.
+%%
+%%     If a defaultoverlayspecification is given, each image is
+%%     surrounded by an actionenv environment (defined by the beamer
+%%     class) with this option as argument. An example usage might be
+%%
+%%     \multiinclude[<alert@+| +->][graphics={height=4cm}]{myimage}
+%%
+%% Requires:
+%%     The keyval package for options processing.
+%%
+%%
+%\RequirePackage{pause}
+\RequirePackage{keyval}
+%%
+%% The command should process the optional arguments.
