 ## Introduction
 
 In order to automate deployment to and from Azure API Management instances, we needed some kind of tooling to accomplish this. In many cases, the Azure Powershell Cmdlets will help you doing things, but in some cases, they just don't go far enough, and/or you want to deploy from a Linux/Mac OS X build agent/client.
