*Required packages*
--------------------

Note that GSAS-II requires the Python extension packages 

* wxPython (http://wxpython.org/docs/api/), 
  * note that GSAS-II has been tested with wxPython 2.x and 3.0.x; It it expected to have problems with wxPython 4.x at present. 
* NumPy (http://docs.scipy.org/doc/numpy/reference/), 
* SciPy (http://docs.scipy.org/doc/scipy/reference/),
* matplotlib (http://matplotlib.org/contents.html)  and
* PyOpenGL (http://pyopengl.sourceforge.net/documentation)

Two packages are used by some parts of the code, but are not
required. If these packages are not present warning messages may be
generated but the vast bulk of GSAS-II will function normally. 

* PIL (http://www.pythonware.com/products/pil/) or Pillow (https://pillow.readthedocs.org). This is used to save
  and read certain types of images.
* h5py is the HDF5 support package. This is (not surprisingly) required
  to import images from HDF5 files. If this library is not present,
  the HDF5 importer(s) will not appear in the import menu and a
  warning message appears on GSAS-II startup. 

Note that the packages listed above are not distributed as part of the Python standard
library and must be obtained separately (or in a bundled Python
package such as Continuum.io's Anaconda or Enthought Inc.'s Canopy; 
we also do some testing using the older Enthought Python
Distribution).  
One exception is the PyOpenGL package. This will be installed into
Python by GSAS-II if not found, so it does not need to be included in
the Python bundle, but the setuptools package
(https://pythonhosted.org/setuptools/) is needed by GSAS-II to install
PyOpenGL.
