We are planning to update the wiki with more information of coding 
back-ends and filters.

AFAIK,
	- backend needs to be a .Net dll.
	- Backends derive from LuceneQueryable (if it queries/stores index 
from/in Lucene), in beagled/LuceneQueryable.cs, which is derived from 
the interface IQueryable (beagled/Iqueryable.cs).
	- They should listen to Inotify events, if applicable

You can look at GaimLogQueryable and LauncherQueryable, two of the 
simple backends in beagle.

Back-ends are integral part of the "beagle" daemon, which does the job 
of crawling, indexing and searching.  D-Bus interface is for the 
external-application to query beagle and get results from it.

Hope this helps!!
