  <longdescription>
Dataproviders are small plugins for applications whose work is to push the 
user’s activities as events in the Zeitgeist daemon. The work of dataproviders 
are limited to pushing events and not consuming. Without dataproviders being 
enabled having exhaustive log of user’s activities is tough as Zeitgeist 
datahub does not track events like opening websites etc.
