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 checksum are appended to possibly existing files. 12# NOTE: Don't use this when running parallel jobs 13# If -a is given, then the list of sets is ignored, and ``*'' is used. 14# 15# After shell glob expansion, the list of sets is filtered to remove known 16# output file names (of the form *SUM, SHA512 and MD5), non-existent files, and 17# subdirectories. If this filtering leaves no files, then no output files are 18# produced. Otherwise the resulting list of files are checksummed and two 19# output files (MD5 and SHA512) are produced. 20# 21 22prog="${0##*/}" 23rundir="$(dirname "$0")" # ${0%/*} isn't good enough when there's no "/" 24.
