      NAME
           rmdel - remove a delta from an SCCS file

      SYNTAX
           rmdel -rSID files

      DESCRIPTION
           Rmdel removes the delta specified by the SID from each named
           SCCS file.  The delta to be removed must be the newest (most
           recent) delta in its branch in the delta chain of each named
           SCCS file.  In addition, the  specified must not be that of
           a version being edited for the purpose of making a delta (i.
           e., if a p-file (see get(1)) exists for the named SCCS file,
           the  specified must not appear in any entry of the p-file).

           If a directory is named, rmdel behaves as though each file
           in the directory were specified as a named file, except that
           non-SCCS files (last component of the path name does not
           begin with s.) and unreadable files are silently ignored.
           If a name of - is given, the standard input is read; each
           line of the standard input is taken to be the name of an
           SCCS file to be processed; non-SCCS files and unreadable
           files are silently ignored.

           The exact permissions necessary to remove a delta are
           documented in the Source Code Control System User's Guide.
           Simply stated, they are either (1) if you make a delta you
           can remove it; or (2) if you own the file and directory you
           can remove a delta.

      FILES
           x-file    (see delta(1))
           z-file    (see delta(1))
