<h2>DESCRIPTION</h2>

<em>g.extension</em> downloads and installs, removes or updates
extensions from
<a href="http://svn.osgeo.org/grass/grass-addons/grass7/">GRASS Addons SVN repository</a> into the local GRASS GIS installation.

extension re-installs the requested extension which may include
updates. All locally installed GRASS Addons extensions can be
re-installed
by <em><a href="g.extension.all.html">g.extension.all</a></em>.

<h2>EXAMPLES</h2>

Download and install <em>r.stream.distance</em> into current GRASS installation

<div class="code"><pre>
g.extension extension=r.stream.distance
</pre></div>

<div class="code"><pre>
g.extension extension=r.stream.distance operation=remove
</pre></div>

<div class="code"><pre>

</pre></div>
