function mm = makemovie(framevec,title,fps,reps,movieformat,itwm_logo,blockpat)

% function mm = makemovie(framevec,title[,framespersec[,reps[,movieformat]]])
%
% makemovie takes the files __MovieD/<framevec(:)>.ppm (usually) created
% with makeframe and writes them either into a file <title>.mpg, or
% into a file <title>.gif. The first is an MPEG animation, the second a
% gif89a animation. 
%
% Selectable movieformats are 'gif', 'mpg' or 'all', movies are written
% accordingly. On exit, the __MovieD and all files in it are removed.
%
% For the gif animation the framespersec argument specifies the
% frames per second (default 10) and the reps argument the
% repetitions (default 1). Gif animations can be viewed with
% Mediaplayer, NETSCAPE, animate, etc.
%	
% If called without arguments, makemovie returns the directory that the
% movie package is installed in.
%
% To create multiple movies in parallel, create a subdirectory
% for each movie in which you execute the makeframe and makemovie
% commands.
%
