# apt-fast v0.02 by Matt Parnell http://www.mattparnell.com, this thing is fully open-source

# Special thanks to Travis/travisn000 from the PCLinux Forums for making improvements that allow
# for more complex apt-get commands. See the thread: http://www.pclinuxos.com/forum/index.php/topic,66385.0.html
