Yep, in the repository there is a demo and its HTML file.
Basically you put in things like this (I've used the C# /// type but I could make it work with /** easily enough)
/// This is my function which does something
/// @param name the persons name
/// @return the name mangled or something
function thisFunction(name as String)
...
endfunction newName
And it produces a nice HTML version of the same thing - it does something very similar for user defined types.
It basically works but I thought I'd ask for feedback before giving it a bit more extensive testing and so on
