</div></div>My suggestion would be to set yourself a goal, for example some small<br>
new feature to add, and then work towards that. At least for me, that<br>
approach usually works better than trying to understand how something<br>
works just by looking at it.<br>

There's a list of project ideas on the wiki which might be suitable:<br>
<br>
<a href="http://trac.xapian.org/wiki/ProjectIdeas" target="_blank">http://trac.xapian.org/wiki/ProjectIdeas</a><br>
<br>
Or if you're interested in a particular area, people might be able to<br>
suggest something related to that.<br>
<br>
Cheers,<br>
