I fear I'm getting a bit lost in all the involved (sub-)projects as we were
originally talking about synopsis as a backend for pyste, but are now talking
about gccxml, pygccxml, pyplusplus, etc.

I couldn't quite figure out what the goal of pygccxml and pyplusplus is,
and how that relates to synopsis. gccxml is a C/C++ parser, and synopsis
contains a C/C++ parser, too, so I can see that in some cases where software
depends on gccxml it may make sense to replace that with synopsis.

However, from my little understanding it appears that pygccxml is - in terms
of scope - more equivalent to synopsis as a whole, i.e. source code introspection.
Why would you want to run on top of synopsis, then ? What is the advantage of
mapping synopsis' own internal representations to pygccxml, of you could do
the same introspection more efficiently inside synopsis ?

What advantage does pygccxml have over synopsis that suggests such an additional
step ?

That's good. What do these tests cover ?
