*GSASII: GSAS-II GUI*
----------------------------------------

File GSASII.py is the script to start the GSAS-II graphical user 
interface (GUI). 
This script imports GSASIIpath, which does some minor initialization
and then (before any wxPython calls can be made) creates a wx.App application. 
A this point :func:`GSASIIpath.SetBinaryPath` is called to establish
the directory where GSAS-II binaries are found. If the binaries 
are not installed or are incompatible with the OS/Python packages, 
the user is asked if they should be updated from the subversion site. 
The wxPython app is then passed to :func:`GSASIIdataGUI.GSASIImain`, 
which creates the GSAS-II GUI and finally the event loop is started.

Keyboard Menu Shortcuts
----------------------------------------

Shortcuts for commonly-used menu commands are created by adding a 
menu command with a "\\tCtrl+" addition such as::

        item = parent.Append(wx.ID_ANY,'&Refine\tCtrl+R','Perform a refinement')

This will allow the above menu command to be executed with a "Control-R" 
keyboard command (on MacOS this will be "Command+R" rather than "Control-R") as well as using the menu to access that action. The following table lists the 
keyboard letters/numbers that have GSAS-II assigned actions.
are system assigned. Note that there are also plotting keyboard commands that are 
implemented in :mod:`GSASIIplot`. 
These can be discovered from the "K" button on the plot menu bar, as they 
vary depending on the type of plot.
