     It's a simple wrapper meant to be called in place of pkexec, it 
passes the request to udevil if the command is mount or umount, 
otherwise it passes it to sudo. I didn't check it with udevil because 
Thunar doesn't invoke pkexec for mount/umount, but it works fine with 
sudo, using zenity as dialog to enter the password. Actually I could try 
to mount/umount with it from the command-line; I didn't think of it 
because it wasn't the goal; actually I even forgot to read the man of 
udevil - shame on me! I posted the source on the list yesterday or the 
day before.
