randbg.pl
v0.1

Copy the randbg.pl script to your favorite bin directory (/usr/local/bin is
usually good).  Then just modify your autoexec file so that the script
is 'Exec'ed before asetroot runs.  The script will scan your asetroot file
for background definitions, then randomly assign those definitions to your
desktops; voila, random backgrounds every time you start.  Check the
example files if you have trouble seeing how it should work.
