# CygBuild, an optimistic attempt to make sometihng like Slackware's
# SlackBuilds for cygwin.
# Thanks to Patrick J. Volkerding and the Salckware team for this perfect way
# to build things, and thanks SlackBuilds memebers.
# Whithout stealing from you all, this could never have happened.
#
# things that are needed here:
# The system needs to be able to build stuff successfully.
# There is no dependency resolution here, please make sure everything's ready.
# Please have util-linux installed.
#
# This script needs an argument for the package's source file
# Examples:
# libsomelib-1.2.3.tar.gz 
# appsomeapp_2-12.34.tgz
