# Slackware build script for hfsprescue
#
# Upstream: https://www.plop.at/en/hfsprescue.html  (Elmar Hanlhofer)
#
# Source note: plop.at's own downloads are dead -- its download host returns
# 403 ("Server unable to read htaccess file"). The source used here is the
# master snapshot from the kaisenlinux mirror, which is genuinely 3.6:
# configure.ac reads AC_INIT(hfsprescue, [3.6 07/04/2023]) and the ChangeLog
# matches upstream's 3.6 entry. Treat the mirror as the source; do not waste
# time trying plop.at.
#
# The zip ships a generated ./configure, so autoreconf is not needed.
