     Name
          rmdel - remove a delta from an SCCS file

     Syntax
          rmdel _-r_SID files

     Description
          The rmdel command 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 delta
          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(CP))
          exists for the named SCCS file, the delta specified must not
          appear in any entry of the p-file).

          The -r option is used for specifying the SID (SCCS
          identification) level of the delta to be removed.

          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.

          Simply stated, the rules are:

          (C)
            if you make a delta, you can remove it.

          or

          (S)
            if you own the file and directory, you can remove a delta.

     Files
          x.file    (see delta(CP))
          z.file    (see delta(CP))
