mod_rewrite help

anyone know how i can rewrite:

http://www.domain.com/dir1/dir2/seed and http://www.domain.com/seed

to

http://www.domain.com/dir1/dir2/index.php?x=seed and http://www.domain.com/index.php?x=seed

 

Something like this may work, not exactly sure, although I do know the first rule will work.

http://www.doriat.com/ has alot of information on this, and help with it.
