Mispelling error
Updated README to announce Resque Worker support coming soon.
Added FAQ to the README.
Restructured the HireFire library and added support for Resque workers.
Added environment specs to ensure correct hire/fire invocations.
Added environment specs to ensure correct hire/fire invocations.
Added Resque rake tasks to Railties.
Added more comments and finished adding Resque rake tasks to Railties. Also had to fix the namespaces for Delayed::Job and Resque to prefix with '::' since it was conflicting with the HireFire modules.
Merge branch 'resque' into develop
Fixed merge conflict, refactored all the code and applied tests for the newly added functional notation.
Updated README to inform that the functional job/ratio notation will be added in 0.1.1 and isn't available just yet (in 0.1.0).
Resque.info[:pending] isn't the correct sum. We need the sum of Resque.info[:pending] + Resque.info[:working]. Otherwise it'll shutdown all the workers while a few may still be busy processing jobs.
Added more use-cases to the tests to make coverage even more solid. Also fixed a certain use-case by implementing additional code for the Standard Notation.
Only load in Railties if Rails 3 or greater is loaded. Otherwise, if Rails 2 is loaded then don't load Railties, and instead just initialize HireFire directly.
Fixes problem with working with the latest Resque gem
