setuid program

[VLD/VMB]

SCCS, at least the SVR2 version, already supports set-UID interfaces
and access control (admin -a option).  All you need then is a set-UID
front-end that checks for fraudulent use, then feeds the command to
the regular SCCS utility.  I have one that I have not been able to
test due to our kernels not supporting System V setuid semantics.
If you really want to try it, send me mail.
