[Super-tux-devel] few updates to README and TODO

[Duong-Khang N. <neo...@us...>]

Hi all,

I have just read the message from Bill Kendrick about a level editor. It could 
be an interesting feature. However, in order to write such an editor, people 
have to know the level file structure. And currently, there's no document 
about it yet. I think that Bill Kendrick is the best person who can achieve 
this work quickly.

Sincerely,
