# Samuel Vasko 2013
# Cmder build script
# Like really a beta
#
# This script downloads dependencies form google code. Each software is extracted
# in a folder with same name as the project on google code. So Conemu becomes
# conemu-maximus5. Correct files are beeing picked by using labels.
# I will move the script for getting files by labels from php to here as soon I feel like it
