#! /usr/local/python
# Play CMIF movie files
# Usage:
#
# Vplay [-l] [-m maginfy] [file] ...
# Options:
#
# -l : loop, playing the movie over and over again
# -m magnify : magnify the image by the given factor
# file ... : file(s) to play; default film.video
# User interface:
#
# Place the windo where you want it. The size is determined by the
# movie file and the -m option.
#
# Press ESC or select the window manager Quit or Close window option
# to close a window; if more files are given the window for the next
# file now pops up.
