  NAME

    comb - Combines SCCS deltas to reconstruct SCCS files

  SYNOPSIS

    comb files

  DESCRIPTION

    The comb command generates a shell procedure (see sh) 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 flag arguments apply to all named SCCS
    files.  If a directory is named, comb behaves as though each file in the
    directory were specified as a named file, except that non-SCCS files (last
    component of the pathname does not begin with s.) and unreadable files are
    silently ignored.  If a name of - is given, stdin is read; each line of
    the 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 stdout.

    The flag arguments are as follows.  Each is explained as though only one
    named file is to be processed, but the effects of any flag argument apply
    independently to each named file.  For each get -e 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 -o flag may decrease the
    size of the reconstructed SCCS file.  It may also alter the shape of the
    delta tree of the original file.  This argument causes comb to generate a
    shell procedure which, when run, will produce a report giving, for each
    file: the filename, size (in blocks) after combining, original size (also
    in blocks), and percentage change computed by:

         100*(original-combined)/original

    It is recommended that before any SCCS files are actually combined, one
    should use this flag to determine exactly how much space is saved by the
    combining process.  The SCCS identification string (SID) of the oldest
    delta to be preserved.  All older deltas are discarded in the
    reconstructed file.  A list (see get for the syntax of a list) of deltas
    to be preserved.  All other deltas are discarded.

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

  FILES

    s.COMB The name of the reconstructed SCCS file.

  NOTES

    The comb command 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.
