4"""
5Run sasview in place.  This allows sasview to use the python
6files in the source tree without having to call setup.py install
7first.  A rebuild is still necessary when working on sas models
8or c modules.
9
10Usage:
11
12./run.py [(module|script) args...]
13
14Without arguments run.py runs sasview.  With arguments, run.py will run
15the given module or script.
