A draft of "REP 115: rosco and roslocate tools for rosinstall" has
been posted here:

http://www.ros.org/reps/rep-0115.html

This REP is meant to codified a variety of threads on ros-developers
and ros-users regarding the roslocate and rosco tools, and also
provide a basis for other tools like rosws.

Discussion/voting for this REP is important as both of these tools
are/will be installed with the rosinstall tool, and thus will have
high visibility.   With respect to roslocate, the REP formalizes the
new options related to distribution-specific lookups.  The rosco tool
is a new tool to be included with rosinstall that has a high-coupling
with the roslocate tool.

Voting guidelines are here:
