# I install this script in /usr/local/bin/makeshorewall.
#
# Usage:
#
#   makeshorewall [ -trhxl ] <version> [ <previous version> ]
#
#      -t      Build tarball
#      -r      Build RPM
#      -h      Build HTML documentation
#      -x      Build XML documentation
#
# If no options are given, all options are assumed.
#
# If <previous version> is given, a patch file reflecting the differences
# between that version and the current version ( <version> ) is
# generated. The directory ./shorewall-<previous version> must exist and
# contain the version against which the patch is generated.
