GIT-CVS sync script

Hi,

I find the included script useful to easily track a CVS repository in
GIT. You can both call it for the initial import and ofcourse for the
subsequent resynchronisation with the parent CVS repository (that's what
the script's about).

Would it be better to provide this as a patch against git-cvsimport-script?

It has been tested on the RTAI-Fusion repository.

With friendly regards,
Takis
