a long standing TODO to document the actual start-up sequence, which is implemented this way since a long time now. There was an unwritten section in the "Linking and Application Structure", which seems the apropriate place for this kind of intricate techincal details. Last week, Benny Lyons was here on visit in munich and he was pondering the idea of an experimental secondary build system, as a way to learn more about the source structure of Lumiera. This reminded me to fill some missing parts of the documentation. Possibly this is also the right moment to land the GTK-3 transition?
