What problems does it solve? It seems like a convoluted way for distributing shared libraries and support applications with the primary application. Couldn't i just put them all ina folder wih a script to se paths?

I've quit using Python, unless forced, because I've gotten too many folders of files that "work on my(the original developer's) machine," but fail on mine because I didn't find or follow a README that said "just" install all the same dependencies and versions.
