2- Downloading and Installing

        2.1- System Requirements:
                - Python version >= 2.4 should be running on the system

        2.2- Installing:
                - Get the code from svn://danse.us/sans/releases/sansmodels-0.4.0
                - Execute the following: 
                        python setup.py install

3- Known Issues

        3.1- All systems:
                - Q range validity of I(q) calculations.
                        Our 1D models of I(q) use the function of the NCNR library 
                        for their IGOR package (Klein, 2006). That library uses a
                        fsat integration technique in some of its models (cylinders
                        and ellipsoids). Integration is done using 76 points in the
                        angle between the axis of the object and the q-vector, which
                        translates in a larger inaccuracy at high q. Integratiing
                        the 2D model I(q,phi) over all orientations of the object
                        will not yield the exact same result as the NCNR calculation
                        for q > 0.3 A-1.

        3.2- Windows:
                - None
