+libnl versions explained
+========================
+
+Once libnl3 hits the archive there will exist 3 versions of libnl.
+libnl1 with libnl-dev  - up until March 2011 the stable version
+libnl2 with libnl2-dev - development version that resulted in
+libnl3 with libnl3-dev - the new stable (API and ABI wise) version
+
+libnl1 has currently a lot of users in the archive and a lot of changes
+happened since its last upstream release in 2008-01.
+
+The plan is therefore to introduce libnl3, port the two users of libnl2
+(freesmartphone.org libs and powertop) to it, remove libnl2 and don't touch
+libnl1 and libnl-dev for now.

+This package uses the simple-patchsys of cdbs.
+
+The following patches are used:
+0001:	Fixes the header inclusion in the Makefiles.
+	This for example make distcheck
+0002:	Includes all generated libraries as linktargets in the pkg-config file.
+	Reason: Currently libnl3 generates a bunch of child libraries.
+	These don't get individual .pc files from upstream at the moment but
+	programs linking against libnl3 using the .pc file mostly need these
+	additional libraries too.
