[ros-users] binary packages dependencies

[Brian Gerkey]

hi Cedric,

You've noticed an aspect our binary packages that's bothered us (the
developers) since the day we started making them, which is that they
contain extraneous build artifacts, sometimes lots of them.

We plan to remove them, starting with the worst offenders, some of
which you've identified.  Ideally, we'd remove the build directory of
every package, but some (ill-behaved) packages export directly from
their build directory; they need to be fixed.

You'll see a lot of benefit from that kind of cleanup.  We could then
explore your suggestion of making runtime and development versions of
each package.  Doing that properly will take some thought, and is
unlikely to happen very soon.

	brian.
