Subject: Re: Reading a class-file and calling it at runtime.

I'm not sure what you are trying to acomplish... but here is a trick i 
use when rails mess with my requires.

def require_relative *args
  path= File.dirname(args.shift)
  args.each { |arg| path= File.join(path, arg) }
  require path
end

This will require the file with full file name. Now you can do

Dir[File.join(File.dirname(__FILE__), '/plugins/*.rb')].each do |file|
  require_relative __FILE__, file
end

That loads every file of directory plugins. Now, if you named the files 
according to rails convetions, ie:

my_class_name.rb for MyClassName class, you can do something like:

plugin_classes= []

Dir[File.join(File.dirname(__FILE__), '/plugins/*.rb')].each do |file|
  require_relative __FILE__, file
  name= File.basename(file)
  plugin_classes << $1.camelize.constantize if name =~ /(.*)\.rb$/i
end

There... it sounds easy, no? :)
