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