Subject: Configuration Options in a new gem

Hi all,

I am learning how to create my own gems today, but I have not been able
to find out how to configure the gem to accept configuration arguments.
If that didn't make any sense let me show you what I mean

In my gem I have a base class, that is setup like this:

Module MyGem
  class Base

    @@config_file = ''
    cattr_accessor :config_file

    def initialize
      @@config = YAML.load_file(@@config_file)
    end
  end
end


I want to be able to set the option for the config at the top of a
script so that I don't have to do it for each class instance.  Something
like this:

MyGem::Base.config_file = '../my_config.yml'

This is not working.  I realized the the cattr_accessor needs
activesupport and I have added the necessary requires, but I am getting
an "undefined method" error when I try to use the gem.  If there is
another way to do this I would love to know.

Sorry, if this doesn't make any sense.  If you would like more details
please let me know.

Thanks

Peer
