Yep, all my extensions are wrapped into packages and all of them
use subpackages which wrap extension modules included as submodules
of those packages... that gives you a very flexible setup since the
__init__.py files let you do all kinds of nifty things to load the
correct C extension (see my previous post).

The main reason for including the extensions in the packages themselves
rather than making them top-level was to simplify installation, e.g.
on Windows (with pre-compiled binaries), you only have to unzip
the archive and that's it... no make install or equivalent is

That one is simple: you run it twice. The first time to load the
DLL and the second time with the break point set in the DLL.
Works with gdb on Linux, not sure about other platforms.
