Wanting a singular packaging tool/vision

At the moment, I use pew to make a temporary virtualenv, install sympy, and run my script. But I have to remember (or read the code to check) what dependencies my script has when I run it, and build a throwaway virtualenv each time.

The solution for this use case used by pyflow is very nice IMHO GitHub - David-OConnor/pyflow: An installation and dependency system for Python
