SYNOPSIS
	$0 [-h host] [-u user] [-intv] -d directory

	Where "directory" contains the comma-delimited list
	of root directories of new ports that you wish to
	add to the Ports Collection.  The name of this directory
	*WILL* matter in regards to the repository!

OPTIONS
	-h host		Use a cvshost besides freefall.FreeBSD.org
	-i		Interactive mode; allow more control over
			where things are placed.
	-n		Do not actually commit anything.
	-u user		Use a different username (default: $u).
	-t		Do more port testing
	-v		Plain vanilla "add it" - no testing at all.
			This option overrides -t.  It is currently
			necessary in order to use this on freefall.

EXAMPLES
	% addport -n -d greatgame,helpfuldev,shoot
		Will show what happens but not actually commit ports
	named "greatgame", "helpfuldev", and "shoot".

	% addport -t -v thisport
		Will not perform testing (does not matter in which
	order -t and -v are used) on port "thisport" but just add it.
