From 47799adc0d1bfb9e0e592dbc9af3eb4680e0c81b Mon Sep 17 00:00:00 2001 From: Casper van Donderen Date: Wed, 9 May 2012 12:35:30 +0200 Subject: Doc: Move some remaining files over for modularization. The files in this change were still in qtbase/doc/src or required for it. qtbase/doc/src should now only contain example documentation and images for the example documentation.
