[Python-ideas] Calling python from C completely statically

[Alberto Garcia]

Hi,

thank you for your response. I've downloaded the sources but I couldn't
find any documentation. In addition I see that there is not a single C/C++
file. What I want to do is calling python from C.
Am I missing something?

Cheers
