#!/usr/bin/env python """ Run sasview in place. This allows sasview to use the python files in the source tree without having to call setup.py install first. A rebuild is still necessary when working on sas models or c modules. Usage: ./run.py [(module|script) args...] Without arguments run.py runs sasview. With arguments, run.py will run the given module or script.
