      5 # Make checksum files for files in ``tardir''.  Usage:
      6 # makesums [-a] [-t tardir] [setname [...]]
      7 #
      8 # If -t is omitted, RELEASEDIR must be set and not empty.
      9 # The ``setname'' arguments comprise a list of files to checksum,
     10 # and may be omitted (in which case ``*.tgz'' is used).
     11 # If -a is given, then the list of sets is ignored, and ``*'' is used.
     12 #
     13 # After shell glob expansion, the list of sets is filtered to remove known
     14 # output file names (of the form *SUM, SHA512 and MD5), non-existent files, and
     15 # subdirectories. If this filtering leaves no files, then no output files are
     16 # produced. Otherwise the resulting list of files are checksummed and five
     17 # output files (BSDSUM, CKSUM, MD5, SHA512, SYSVSUM) are produced.
