Comment (by cnielsen):

 Thanks for all the comments. I believe I have fixed all the errors
 mentioned above (except the description.html $date thing, I'm not sure how
 to fix that one).

 I removed the problem in r.drain that dylan mentioned... Something is
 still needed there but I couldn't find a working solution. I wanted an
 error to come up if the user put in an invalid direction raster, but the
 NULL cell value was coming up as a false positive... If someone has an
 idea let me know.
