+Important Notice (concerning development and support)
+-----------------------------------------------------
+
+After developing the core parts of the library and maintaining it for
+a while, supporting users and co-developers in several projects, I
+decided to stop actively developing the library further. This is
+solely due to other time-consuming things in my life, so I won't be
+able to help you getting your project to run. By now there are lots of
+forks of the library and example programs using it (try Google'ing it
+or look at the GitHub forks). I still incorporate pull requests and
+bug fixes and look after keeping the build farms happy with the source
+(Travis CI, Launchpad), but can't help your individual projects.
