 <h2>DESCRIPTION</h2>
 
-<b>wxGUI</b> is native <em>Graphical User Interface</em> (GUI) for
-GRASS GIS written in <a href="http://www.python.org">Python</a>
-using <a href="http://www.wxpython.org">wxPython</a> library.

-<h3>Starting the graphical user interface</h3>
-If the wxGUI is not the default user interface, it can defined as default by
-typing at the GRASS GIS command line prompt:
-
-<div class="code"><pre>
-g.gui -u wxpython
-</pre></div>
-
-Alternatively it may be defined in GISRC file
-(<tt>$HOME/.grass7/rc</tt> on GNU/Linux, <tt>$APPDATA\GRASS7\rc</tt>
-on MS Windows) by <tt>GUI</tt> variable
-
-<div class="code"><pre>
-GUI: wxpython
-</pre></div>
-
-or by the environmental variable <tt>GRASS_GUI</tt>.
-<p>
-The GUI can be quit by selecting the 'File -&gt; Exit GUI' menu item.
-<!-- is &rarr; allowed? -->
-On MS Windows when GRASS is launched without an interactive command line
-this will end the entire GRASS session. In other cases the terminal
-window will remain running; type <tt>exit</tt> at the command prompt
-to end the GRASS session.
-<p>
-The GUI can be restarted from the GRASS command line prompt by typing
-
-<div class="code"><pre>
-g.gui wxpython

-
-To restart with previously saved workspace file:
-
-<div class="code"><pre>
-g.gui wxpython workspace=file.gxw
