Re: [ros-users] rosdep and interdependent rosdeps

Basically, the brew installer for rosdep needs to also accept a
dependency list, which is partly described here:

http://www.ros.org/reps/rep-0111.html#dependencies

In REP 112, the source manager specifies this external to the
rosdep.yaml file in order to keep metadata together. In the case of
brew, I imagine it would be specified within the rosdep.yaml file.
This is not well-exercised yet, so we can work with you on making this
easy to do.
