*makeLinux: Create Linux Shortcuts*
===================================

This script creates a menu entry for Gnome & KDE desktop managers
and puts it in a place where it can be "indexed."

This is a work in progress as I learn more about shortcuts in Linux.

Run this script with one optional argument, the path to the GSASII.py
The script path may be specified relative to the current path or given
an absolute path, but will be accessed via an absolute path. 
If no arguments are supplied, the GSASII.py script is assumed to be in the
same directory as this file.
