DonkeySpec

DonkeySpec acts as a pager of a specification that summarizes the system well, thus technicians and non-technicians can understand it easily and then can communicate well. It faetures actors in which people are the intended users of the system?, features: Which features exist from a user's perspective?, functions: Which parts of the system exist from a technical perspective?, they can overlap with features, but are typically not the same, and Which third party applications are integrated or affected by the system? The editor has a nice and clean UI and provides cool goodies such as Freemind and Excel integration.
