removing subsytems

[Lloyd J. Lacomb]

Is there anyway to use inst (or some other tool) to remove a whole
subsytem that I installed with inst.  I installed the SCCS subsystem
under 3.1 some time ago and it was updated when I installed 3.2, but
now I no longer need it.  Is there some easy way to have all the files
associated with that subsystem removed.  Also when 3.3 comes along can
I not select SCCS and have it not only not install 3.3 SCCS but remove
3.2 SCCS. 

Thanks,
Lloyd
