+Formatter for automatically generating step files for Cucumber. It's how I roll.
+
+If you have a step like this:
+
+``` gherkin
+Given I set something up
+```
+
+And you set up the formatter like this:
+
+```
+cucumber -f Cucumber::StepWriter --out features/step_definitions
+```
+
+Then `features/step_definitions/given/i_set_something_up.rb` will be generated.
+
+TODO:
+
+* If you want it to generate for different languages, I take pull requests.
+* Otherwise, I'll just add whatever I need when I need it.
