2"""
3Run sasview in place.  This allows sasview to use the python
4files in the source tree without having to call setup.py install
[3a39c2e]5first.  A rebuild is still necessary when working on sas models
[a3e5455]6or c modules.

8Usage:

[6fe5100]10./run.py [(module|script) args...]
11
12Without arguments run.py runs sasview.  With arguments, run.py will run
13the given module or script.
