From maintainer Edd Barrett.
The TeXworks project is an effort to build a simple TeX front-end
program (working environment) that will be available for all today's
major desktop operating systems-in particular, MS Windows (XP and
Vista), typical GNU/Linux distros and other X11-based systems, and Mac
OS X. It is deliberately modeled on Dick Koch's award-winning TeXShop
for Mac OS X, which is credited with a resurgence of TeX usage on the
Mac platform.
