We have created several new tools that you may find useful which we would like to make available to you to try free of charge.  If you like to tinker, this site is for you.  Please understand that any software made available through the Zephyr Labs page may either be a pre-release version (or possibly not intended for release as a product) in which cases there may be limited if any documentation or support available (with the exception of the SDK which is an actual product).  This is also a good place to voice your feedback with regards to Zephyr Labs requests or even product feature requests.
