Is a BASH script that calls mencoder to generate a movie file from a set of png
files in a directory ../png/ relative to the directory it is started from.  It
also requires FFMPEG as it uses that libavcodec for the output codec as well as
parsing the input PNG files.  It takes one optional argument, the resulting
filename of the AVI movie (with .avi extension, don't forget!).  No arguments
means that the file will be called 'animation.avi' in the directory it is
started from.

It generates a AVI file using the MJPEG codec, the same that Canon digital
cameras use so hopefully it is portable enough to pass around.  It also uses a
16 bit colorspace (I think) as set in the format variable.

The script itself should be verbose enough to read.  The frame per second speed
is completely adjustable, and is generated by

fps = (1 / frame_time)*speed_factor

where frame_time is the time covered by each individual frame, i.e. the
exposure time if it's images from a telescope we're talking about.
