		<description><![CDATA[netdisco can be a pain&#8230; even just getting it to run&#8230; I found some neat installation scripts for installing netdisco on some other linux flavors, but I prefer ubuntu. I took those scripts and quickly hammered out one that&#8217;s ubuntu-specific. It&#8217;s not as pretty, and doesn&#8217;t allow you to do as much config by responding [...]]]></description>

The only prerequisites are libxml (and libcurl if you want to be able to run the tests). However, there isn&#8217;t really a [...]]]></description>
