Sorry for me being slow on REP 110.

I updated the REP document still on
http://code.in.tum.de/indefero/index.php//p/rosinstall2/source/tree/master/rosinstall-REP.txt

For now I suggest in the REP to use rosws as name. I cut down the 
diverse commands init, update, add, remove, ... to just install. Which 
makes the REP look a bit silly, as I list 18 use cases most of which now 
are served by "manually update your .rosinstall, then run 'rosws install .'"

To reduce the wait time for the features I might, if Tully agrees, 
provide status, diff, info as -- options in rosinstall as it is, then 
the REP would really just change the syntax, not introduce features.

regards,
