So your plan is to also package lustre-shine? Have you gotten in touch
with the Lustre packaging team, then?

This doesn't explain what makes the interface "efficient".
In any case, I would recommend getting in touch with either pkg-lustre
(http://pkg-lustre.alioth.debian.org/) or the PAPT team
(http://wiki.debian.org/Teams/PythonAppsPackagingTeam). I'm not
qualified myself to sponsor python stuff.
