Brief: Syncronizing your ports collection
and seeing what to upgrade and upgrading it.

Preliminary: You need 'cvsup' and 'portupgrade' from ports.
You'll also need a cvsup file.

 1.) cvsup -g -L2 /etc/cvsup/ports
 2.) portsdb -Uu
 3.) portversion -vL =
     (or pkg_version -L =)

 4.) portupgrade -ar


-----------
Use portsnap:
(Much quicker method)
	
	Notes:
		* portsnap is now part of the base system
		* if not, use ports-mgmt/portsnap
		
	- I suggest removing /usr/ports (rm -rf /usr/ports) because
		portsnap functions better when it's created all of the contents
		of /usr/ports

	- Once you do that, run "portsnap fetch && portsnap extract" to
		download and extract a new ports tree.

	- After you have a populated ports tree, you can periodically update it
		by running "portsnap fetch update" and use "portversion -vL =" to see
		what's out of date.

		* Note that some portsnap versions don't like multiple commands in the same line.  You may have to run "portsnap fetch && portsnap update".

		* crontab:
			0	16	*	*	*	root	portsnap cron && portsnap -I update

			- or -

			0	16	*	*	*	root	portsnap -I cron update
