# This script creates a new source tarball and extracts it in the build
# directory. The source directory and tarball are renamed to  Debian-
# conform names.
# Then the debian directory is created from a diff file and prepared for
# the new build. For this the following steps are executed:
#
# 1. cd freecad-X.Y.xyz
# 2. patch -p1 < .../debian/diff/freecad_hardy.diff
# 3. dch -v X.Y.xyz-1hardy1 "New release for Ubuntu 8.04 (Hardy Heron)"
# 4. debuild
