# Binary for syncing xbps with a list
#
# HOWTO:
# Make sure to install xtools and that there is a
# repository.list, which should be initialized with xpkg -m > ~/repository.list
#
# Add whatever package you want to install, and run xsync to sync your
# list of packages with the new list

set -e

xpkg -m | sort > /tmp/xsync-installed
cat ~/repository.list | sort > /tmp/xsync-spec

# You can add the -n flag to dry-run and see what will happen
