#Py_GetBuildInfo()
#Py_GetCompiler()
#Py_GetPlatform()
#etc... see https://docs.python.org/3/c-api/init.html

#however we need extra modules to be able to fire up and interpretor (or even call Py_Initialize() and other cool functions!)
#we namely need a 
#signal+faults handler, parser+tokenizer, memory allocator, threading, weakref, io and codecs
#and of course several os modules
#this will depend on your system and will determine how python runs the system

#strangely enough, the os module is Modules/posixmodule.c
#it contains both linux and windows functions. The catch is that it uses config/{os}/pyconfig.h and config/{os}/config.c to find OS functions which needs
#an extensive configuration process. Find a specially tailored pyconfig.h's for several systems in config directory
#these are put here below
