/**
* Protobuf for the Appc image manifest JSON schema:
* https://github.com/appc/spec/blob/master/spec/aci.md#image-manifest-schema
* Where possible, any field required in the schema is required in the protobuf
* but some cannot be expressed, e.g., a repeated string that has at least one
* element. Further validation should be performed after parsing the JSON into
* the protobuf.
* This version of Appc protobuf is based on Appc spec version 0.6.1.
* TODO(xujyan): This protobuf currently defines a subset of fields in the spec
* that Mesos makes use of to avoid confusion. New fields are going to be added
* when Mesos starts to support them.
