Thank you. What does Web::Mime::get_mime_type do? Perhaps you
could/should be using my centralised database in MIME::Types -- I'm
planning at some point on extending that in two ways. First, I plan on
using the freedesktop.org shared mime database as an option, and
second I plan on implementing libmmagic in pure Ruby (so you don't
have to trust the extension of the file if you don't choose to do so).
