   * Resty v1 series was using `gopkg.in` to provide versioning. `gopkg.in/resty.vX` points to appropriate tagged versions; `X` denotes version series number and it's a stable release for production use. For e.g. `gopkg.in/resty.v0`.
   * Development takes place at the master branch. Although the code in master should always compile and test successfully, it might break API's. I aim to maintain backwards compatibility, but sometimes API's and behavior might be changed to fix a bug.
