/*
LyX for Windows Launcher
Author: Joost Verburg
This will be installed as lyx.exe.
The application will setup the environment variables based on registry
settings and obtain the command line output of lyxc.exe, which can be shown
while debugging or in case of a crash. Version information and an icon are
also included.
