Can a Python module be touched by sys.path?

Library modules should certainly not be touching sys.path themselves. Instead, you’d normally have a hashbanged-script outside the package that you use to instantiate and run the app, and it’s in this trivial wrapper script you’d put deployment details like sys.path -frobbing.

How to modify the sys.path list in Python?
