#
# This script determines the revision number used to build FreeBSD packages
# and syncs a local ports directory to match it.
#
# USAGE: sync-ports [name or abs_path]
#
# REQUIREMENTS: textproc/jq, ports-mgmt/poudriere (optional)
#
# If the argument is not an absolute path, the script will treat it as
# the name of a poudriere-managed ports directory.  If poudriere is
# not installed, it will use /usr/ports as the ports directory.
#
# If the argument is not specified, it defaults to "default".
#
# The script uses uname to choose which pkg jail to sync with.
# You can specify PKG_SERVER, PKG_JAIL, and/or PKG_URL in the
# environment to override the default options.

# Set the path
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin
