           _C_o_m_b generates a shell procedure (see _s_h(1)) which, when
           run, will reconstruct the given SCCS files.  The
           reconstructed files will, hopefully, be smaller than the
           original files.  The arguments may be specified in any
           order, but all keyletter arguments apply to all named SCCS
           files.  If a directory is named, _c_o_m_b 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 ssss....) 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 generated shell procedure is written on the standard
           output.

           The keyletter arguments are as follows.  Each is explained
           as though only one named file is to be processed, but the
           effects of any keyletter argument apply independently to
           each named file.

           ----pppp_S_I_D   The _SCCS _I_Dentification string (SID) of the oldest
                   delta to be preserved.  All older deltas are
                   discarded in the reconstructed file.

           ----cccc_l_i_s_t  A _l_i_s_t (see _g_e_t(1) for the syntax of a _l_i_s_t) of
                   deltas to be preserved.  All other deltas are
                   discarded.

           ----oooo      For each ggggeeeetttt ----eeee generated, this argument causes the
                   reconstructed file to be accessed at the release of
                   the delta to be created, otherwise the reconstructed
                   file would be accessed at the most recent ancestor.
                   Use of the ----oooo keyletter may decrease the size of the
                   reconstructed SCCS file.  It may also alter the
                   shape of the delta tree of the original file.

           ----ssss      This argument causes _c_o_m_b to generate a shell
                   procedure which, when run, will produce a report
                   giving, for each file:  the file name, size (in
                   blocks) after combining, original size (also in
                   blocks), and percentage change computed by:
                          100 **** (original - combined) / original

                   actually combined, one should use this option to
                   determine exactly how much space is saved by the
                   combining process.

           If no keyletter arguments are specified, _c_o_m_b will preserve
           only leaf deltas and the minimal number of ancestors needed
           to preserve the tree.

           _C_o_m_b may rearrange the shape of the tree of deltas.  It may
           not save any space; in fact, it is possible for the
           reconstructed file to actually be larger than the original.
