I have written a simple shell script which register a package into CVS
using the .dsc through the following steps :

	o extract sources using dpkg-source -x
	o untar the .orig archive
	o import the upstream version
	o import the debian modifications

I don't know if two cvs import commands can hurt.

The script is included after my signature. Any comments welcome.
