# Script designed to make add packages into wip easier.
#
# Just cd to the package directory and run ../import-package.sh
#
# It will automatically create a nice import message based on DESCR
# and PKGNAME, set up the CVS tags correctly and autodetect what CVSROOT
# to use. It also shows you what files will be imported, reminds you
# to run pkglint(1) and asks for confirmation before doing anything.
