# PORTVERSION auditing script
#
# For many port tools to work correctly, it is of utmost importance that
# PORTVERSION/-REVISION/-EPOCH of a port is a monotonic increasing sequence
# over time. See also
# <http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/makefile-naming.html>
# for more information. Tools that won't work include pkg_version, portupgrade
# and portaudit. One common example is an accidentially deleted PORTEPOCH.
#
# This scripts compares version numbers with previously known ones, and is
# primarily intended to be run from a (non-root) cron job.
#
# If you simply call it, it will compare all ports with their INDEX entry
# and complain if version numbers have gone backwards. You need and old
# INDEX for this, of course. An up-to-date INDEX will accomplish nothing.
#
# To use the script as intended, do the following (assuming you want to
# run the script as user `ports'):
# install port sysutils/pkg_install-devel (optional)
# mkdir -p /var/db/chkversion
# touch /var/db/chkversion/VERSIONS
# chown -R ports /var/db/chkversion
# and enter chkversions.pl into the crontab of ports, or run it by hand
# if you can spare the time.
