#!/usr/bin/env python
# dsx is Mandrakesoft's Xtart modified to work with a Gentoo Linux system.
# Gentoo doesn't use a wmsession.d directory, so we're going to accept the
# /etc/X11/Sessions executables as our menu and our command parameters.
# I also tried to increase the robustness of the entry checking and make the
# error messages less condescending.
# The 0 option for "no wm" was removed. I altered it to run option 1 instead.
### Original copyright / license message from Xtart... ###
