Wow, nice looking, concise and it even supports things like
[background=screen]

But now, I've another problem; I'd like to type:

f(x) = .........
     = ...+...+...+...
       +...+...
     = ...
f(x) = .....

BTW: How to type matrices?

Groeten,

Tobias

PS: Disscussion point:
    should we offer \sqrt[n]{x} as LaTeX does, or should we stick to
    plain ( \root n\of x )
