========================================================================
One-step Debian package generation script.
========================================================================

This script takes a git-version-controlled tree hierarchy containing
a proper debian/ directory for package generation, does a temporary
clone and builds debian packages from it.

Added value :
* automatically generated a proper *.orig.tar.gz as required by debuild.
* make sure the build it not polluted by any local non-commited files
* keep the original tree hierarchy clean

This script should be generic enough to be used in other programe.  It
might be confused by stray version names with strange or worse, evil,
characters, but if you name your package "little bobby tables" you
deserve to to all this by hand.
