faq5.html - # unset RELEASEDIR DESTDIR

While building OpenBSD 5.1-stable I had much trouble that could have
been avoided if the FAQ specified one little detail about the release
process:

# unset RELEASEDIR DESTDIR

It also might have helped had I read the manual for release(8).

Here is a link to a discussion of my troubles in Daemonforums:

http://www.daemonforums.org/showthread.php?t=7125

My proposal to FAQ5 includes moving the reference to the release(8) manual up
to just after the <h3>Doing a Release</h3> phrase.

And to include this command in the release process:
    # unset RELEASEDIR DESTDIR

 These files can now be used to install or upgrade OpenBSD on other
