Fork of Mighty Interactive's fedex plugin (no longer available), updated to support v7 of the Fedex API. NOTE: I am no longer maintaining this library. There is at least one fork that supports v8. If you are interested in taking this over please let me know so I can remove this. Thanks!
There's no need for this to be a plugin. Please follow the guide here: http://yehudakatz.com/2010/04/02/using-gemspecs-as-intended/
