+- Enhance gi-find-deps.sh: gnome-weather came up with a nice idea
+  of specifying all dependencies in a pkg.requires(..) list
+  (hopefully this counts as standardized). Enhance the scanner to
+  identify this listing method of dependencies (bnc#811652).
+- Add pcre-tools Requires to the main package: gi-find-deps.sh uses
+  pcregrep for multi line matching.
