+// Package runtime includes helper functions for working with API objects
+// that follow the kubernetes API object conventions, which are:
+//
+// 0. Your API objects have a common metadata struct member, TypeMeta.
+// 1. Your code refers to an internal set of API objects.
+// 2. In a separate package, you have an external set of API objects.
+// 3. The external set is considered to be versioned, and no breaking
+//    changes are ever made to it (fields may be added but not changed
+//    or removed).
+// 4. As your api evolves, you'll make an additional versioned package
+//    with every major change.
+// 5. Versioned packages have conversion functions which convert to
+//    and from the internal version.
+// 6. You'll continue to support older versions according to your
+//    deprecation policy, and you can easily provide a program/library
+//    to update old versions into new versions because of 5.
+// 7. All of your serializations and deserializations are handled in a
+//    centralized place.
+//
+// Package runtime provides a conversion helper to make 5 easy, and the
+// Encode/Decode/DecodeInto trio to accomplish 7. You can also register
+// additional "codecs" which use a version of your choice. It's
+// recommended that you register your types with runtime in your
+// package's init function.
+//
+// As a bonus, a few common types useful from all api objects and versions
+// are provided in types.go.
