Within the FX::Generic namespace are a collection of compile-time programming tools similar to those provided by the Boost library or Loki libraries. However what is provided here is very much a subset of either of those two libraries.
If you want a full explanation of how this works and how to use it, please consult "Modern C++ Design" by Andrei Alexandrescu. These facilities follow that book somewhat but have also incorporated ideas from Boost and other places.
