KDE Frameworks is a collection of libraries and software frameworks by KDE
that serve as technological foundation for KDE Plasma 5 and KDE Applications
distributed under the GNU Lesser General Public License (LGPL) [1].

The work is based on what we have in the KDE testing repo [2].

This is the next big step in updating the KDE Desktop and its Applications
to anything less dusty.

With this change, `USES=kde:5` is now a valid option. Ports that need to depend
on KDE Framework can now set:
	USES=kde:5
	USE_KDE=<framework1> <framework2> ... <frameworkX>

For example: www/qupzilla-qt5 can depend on sysutils/kf5-kwallet via:
	KWALLET_USE=            KDE=wallet

I would like to thank Raphael and Adriaan for reviewing the ports in the testing
repo :)
