Need help with Portfile with only subports ...

[Edward Maros]

I am working on splitting swig extensions out of a source package to
better facilitate building of language extension packages. Previously
this was all done in one Portfile with each language being a subport of
the main package.

Is it possible to have a Portfile which does not supply a main port, but
instead only subports?

Should I think differently about how to solve this issue?

Thanks,
