3ds - ase fileformat ??

Well, I´ve been looking all around for a nice-model loader, but couldn´t find one.
So I´ve decided to write my own. But where can I find the file-format for the ascii-3d studio-files?? (it´s not on wotsit.org)
Well and can someone tell me how do I access the data in a file?? I hate i/o!!!
Ok thanks,
