Yes, that is the plan.   They will be optional dependencies of rospkg,
and eventually all would be combined into a 'ros' bootstrap debian
that was distribution-independent.   It's also possible that some of
the other binaries in ros/bin could go in this -- in particular, the
python scripts that follow the 'import foo; foo.main()' sort of

My only concern with rospack is librospack, which could use some
improvements before it goes bigger.
