[C++-sig] how do I instantiate templates in pyste with types defined in different files?

That doesn't do it.  My template declaration is in one
file.  The actual types are in another.  There is no
way for me to tell pyste where the actual types are
when I try to instantiate the class.

For example,

Test = Template("Test","test.h")

Test("B","testB") <-- these didn't work because when
the pyste code generator tries to instantiate the
class, it doesn't include the a.h or b.h because there
is no mechanism to tell it how to do so.

This didn't work either:

I tried declaring the class as a typedef:

---- somefile.h ----
#include "test.h"
#include "a.h"
typedef Test<A> TestA

Then in pyste

Pyste doesn't complain, but doesn't generate any
functions or constructors or anything.  It would
generate something like this:
class_<Test<A>, boost::noncopyable >("TestA", no_init)

Any ideas? Or ways around this?
