Comment (by jdemeyer):
Replying to [comment:7 fbissey]:
> OK so if (in the general case) the spkg is installed `OptionalExtension`
returns `Extension` but what does `CythonizeExtension` which is the
alternative result does?
I cannot really parse your question, but I'll try to answer it anyway:
`CythonizeExtension` is exactly like `Extension` except for the
`skip_build` attribute. There is some code added to `src/setup.py` which
checks this attribute. If `skip_build`, then the build (i.e. the `foo.c`
-> `foo.so` part) of the extension is skipped.
