Where ndoc executable binary can be found? All I have managed to find in Ubuntu repos is some other .NET program. Erlang's eDoc seems to have completely different interface, at least I cant find any binary wrapper for edoc module (I mean for this: http://www.erlang.org/doc/apps/edoc/chapter.html#Running_EDoc)
