#Custom debian/rules snippet used for building MythTV packages that come from MythTV's github location

#Figure out what we're working with by parsing the project and debian changelog

#To make sense of these sed rules that are used:

#  Sample version string: 

#                  Version: 1:0.25.0+master.20101129.a8acde8-0ubuntu1

#  /^Version/!d  -> only version line from dpkg-parsechangelog

#  s/.*1:0.//   -> kill the epoch and Version bit and 0. leading the version

#  s/-.*//      -> kill everything after and including the -

#  s/+.*//      -> kill everything after and including the +

#  s/.*+//      -> kill everything before and including the +
