Form Filler

Is there an equivalent in Ruby to the Perl modules which can "fill out
an html/http form"?

Given a hash, I'd like to either get the query string to append to the
URL for GET's, or the POST contents to append for POST's, as if the
hash was the form[field] = value. The routine should handle the url
encoding and the like.

Any luck?
(If not, anyone up for a quick few lines of Ruby ninjahood?)

Ara's time machine is almost as good as Guido's time machine, it seems.

Oh, and someone apparently hacked up a Ruby WWW::Mechanize which is supposed
to do this.

Excellent, most appreciated.

Forgive my RFC ignorance, but is the same string appended to the URL
for GETs and sent as the bod for POST's? Or is there a difference in
the encoding somehow?
