<h2>DESCRIPTION</h2>

<p>
This program allows user to start a selected graphical user interface (GUI)
from the command line prompt.

<p>
GRASS 7 has a new GUI based on wxWidgets, written in Python:

<ul>
<li><b>wxpython</b> - New wxPython based GUI aka
    <a href="wxGUI.html">wxGUI</a></li>
</ul>

The old <em>gis.m</em> and <em>d.m</em> Tcl/Tk GUIs from GRASS 6 have been removed.
<p>
If the <b>-u</b> update flag is given or the <em>g.gisenv</em>
<tt>GRASS_GUI</tt> variable is missing, then the <tt>GRASS_GUI</tt>
variable is permanently changed and the selected GUI will be used
as the default UI from then on.


<h2>NOTES</h2>

Valid values for GRASS_GUI are <tt>text</tt> and <tt>wxpython</tt>.

<em>g.gisenv</em> variables are stored in the user's home directory
in a hidden file called "<TT>.grassrc7</TT>". They are not shell environment
variables and the "rc" file is not a classic UNIX run command file,
it just contains persistent GRASS variables and is not executed.
