(Rails) Reloading "lib" files without having to restart server...?

ruby-on-rails file reload

Is there any way in Rails to have the ENV reload "lib" files without having to restart the server? I'm working with some classes that I have inside a module in "lib". However, in order to see my changes I must restart the server each time. I'm guessing this is the way Rails is intended to work, but it is quite tedious when developing library files and/or plugins.

Surely I'm going about this wrong....?

EDIT 1

Neither answer 1 nor 2 worked for me. Instead I was presented with errors from the controllers that made use of the Module. FYI, I have 3 files in my "lib/xmlitems" directory. I attempted to load that subdirectory then I referenced the single file that "requires" all other files. Am I to individually load all files?

For Rails 3 and Rails 4.0, vary the instructions given in @txwikinger's answer. In your environments/development.rb file, add the lines:

ActiveSupport::Dependencies.autoload_paths << File::join( Rails.root, 'lib')
ActiveSupport::Dependencies.explicitly_unloadable_constants << '<my modules in lib>'
