Split ogre_wrap?

Is it possible to split ogre_wrap.cxx into files?

A huge source file(more than 13M) costs too much time to compile -- and wasting dual-core CPU.

Each time, when a slight change made, the whole file must be recompiled.
A single compiling error causes another recompilation.

Split it into pieces must be much better.

AFAIK someone is already working on this:

That is stuff boost::python (and probably pyplusplus) do natively, and still people try to hassle with swig...
