+For bug reports, open an [issue](https://github.com/jamesarosen/Timecop.js/issues)
+on GitHub.

+Timecop.js has a ‘commit-bit’ policy, much like the Rubinius project
+and Gemcutter. Submit a patch that is accepted, and you can get full
+commit access to the project. All you have to do is open an issue
+asking for access and I'll add you as a collaborator.
+Feel free to fork the project though and have fun in your own sandbox.

+ * not picky about spaces around arguments
+ * all code must pass JSLint with fairly strict settings
