We migrated most of what we were able to do with Deltawerken to QCMagritte.
We prefer you to use QCMagritte.
Deltawerken is the Seaside framework we used to build VBridge and StoryBoard.
It is more tightly coupled to building web applications than Magritte is, and therefore
a lot easier to configure.
Pier-Security is unrelated.
