So I'm trying to see if Python adds language features that are easier to use in Linux for quick purposes like converting a raster to sectional image files and compressing them.

Trying to make this multi platform.

So the question then becomes, since I have a testing build location so as not to fuck up my host system, how do I point PyCharm to the python bindings AND the installed lib in its custom location ?

See this kind of setup information is something that would make getting started with things like this much easier and quicker.

Can't tell me there isn't a purpose for this. This seems like a reasonable use-case.
