   Packages contain all the necessary information to install your application or group of applications.
   The approach to decribing the applications is to use a YAML file that provides all the necessary information to help facilitate searching for your application hosted in a Package Registry and to install your application to a platform.

   To make it easy to customize a package, the YAML files are templated.  The final version of the YAML file, with all values substituted is known as the release `manifest`.
   Skipper currently understands how to deploy applications based off a YAML file that contains the information needed for a Spring Cloud Deployer implementation to deploy an application.  It describes, where to find the application (either a http, maven or docker location) , application properties (think Spring Boot `@ConfigurationProperties`), an deployment properites (how much memory to use).
  -Future version of Skiipper may provide support for other YAML manifest file formats, e.g. Cloud Foundry, or Kuberentes resource files.
