Backdrop in Python

# This is a little program I call via cron to change my desktop every
# few minutes.  With no arguments it goes to my directory of backdrop
# images and picks a valid image at random.  If I specify a path and a
# file the program will put it up as the display.

# I don't want to fill up my inbox with emails from cron telling me that
# X isn't running, so I check first.

<!-- I left the RC file almost totally alone, but I run two monitors on a Matrox G400, and so I had to do the following: -->
