The output of this program is a shell script. It takes no actions itself except to build a database so that subsequent runs are faster.
One BIG assumption: you build your ports by hand and keep the list of what you want to be installed in /usr/ports/makefile.
This program bites off more than it can chew. Upgrading FreeBSD ports is really difficult and this program helps.
