PPMOC is a moc replacement for template classes. Its main feature include:

Entirely implemented using the boost preprocessor library. Yes, this means you don't have to call any external tools !
Unlike Qt's moc, all macros are fully processed. For instance you can write any wrapper macros on top of PPMOC to simplify the generation of redundant declarations
Allows to use all the Qt's meta object mechanisms (signals, slots, properties, reflexivity, etc.) with templated classes !
The types of your properties, signals and slots can be either typedef-ined types or templated types, or even #defined types.

Note that this tool/library is more like a proof of concept rather than a mature project. Anyway, I think it might be useful to many people as it is to me.
