A few tips from Jaka Kranjc

Jaka "lynx" Kranjc was nice enough to send in some helpful quick tips for readers.

use cleanse --sweep to delete unnecessary sources and binary caches.
Files are kept if any spell/version in any grimoire could use them.

You have no idea why you have package X installed. You don't need it, but
perhaps some other installed package does? Check with
gaze depends X 2

When dispelling, you can also automatically dispel any orphans. Orphans?
Orphans are packages that nobody needs, so if X depends on Y and you dispel
X, Y is an orphan and probably just takes up space.
dispel --orphan ask-yes X
see the dispel man page for further info, there is a lot more to this!

You can quickly downgrade a spell (eg. X at 2.1.1) if you have the cache
tarball of a previous version with:
dispel -d X 2.0.1
