2"""
3Run sasview in place.  This allows sasview to use the python
4files in the source tree without having to call setup.py install
5first.  A rebuild is still necessary when working on sas models
6or c modules.
7
8Usage:
9
10./run.py [(module|script) args...]
11
12Without arguments run.py runs sasview.  With arguments, run.py will run
13the given module or script.
