Rails - Jun 2008 - putting require on environment.rb vs on model/controller file

I''m just curious to know is there any benefit in putting require in
environment.rb vs in model/controller file? I guess it''s always better
to use it in environment.rb, even when only one controller requires
it, since once it''s loaded it''s always there anyway. Am I
right on
this?

I''d opt the other direction... if only one controller requires
whatever,
that controller should say so. When I see something in environment.rb, I 
expect to see wide-spread usage in the application.

Seeing "require ''will_paginate''" in environment.rb
makes sense, as all
our controllers paginate.

Seeing "require ''pdf/writer'' and require
''pdf/simpletable'' in just a few
controllers shows that only those controllers deal with requests for 
generating PDF files.
