Rails Initialization - where to put requires?

While upgrading my app to use Rails 2.1, the clean place to put my gem
requires makes my non-gem requires stand out as needing a place to
live. Where is the best place to put requires of either libs from my
app (in the lib directory) or standard libs (such as digest/md5)?
Right now, I have a huge paragraph of these requires just before my
Rails::Initializer.run.

It seems like maybe I should create an initializer for these. What is
the standard wisdom here?

You can create a myrequires.rb in config/initializers and put all your
require in there, I guess. there's nothing magical about the name
myrequires.rb, btw. I chose it because it's unlikely to conflict with
something else.
