[Rock-dev] Typelib and template arguments

[Sylvain Joyeux]

What typelib is not happy about is that types should start with a /
(but can contain spaces), and should not have spaces after the commas.
Moreover, the name separator is / not ::, so you want to add:

  /Eigen/Matrix</double,3,1,2,3,1>

The reference is an issue though.

In general, the gccxml importer does not register typedefs like this,
but instead resolves the full name to the opaque name (i.e. the matrix
above is only seen by typelib as /Eigen/Vector3d).
