+// deepcopy-gen is a tool for auto-generating DeepCopy functions.
+//
+// Given a list of input directories, it will generate functions that
+// efficiently perform a full deep-copy of each type.  For any type that
+// offers a `.DeepCopy()` method, it will simply call that.  Otherwise it will
+// use standard value assignment whenever possible.  If that is not possible it
+// will try to call its own generated copy function for the type, if the type is
+// within the allowed root packages.  Failing that, it will fall back on
+// `conversion.Cloner.DeepCopy(val)` to make the copy.  The resulting file will
+// be stored in the same directory as the processed source package.
+//
+// Generation is governed by comment tags in the source.  Any package may
+// request DeepCopy generation by including a comment in the file-comments of
+// one file, of the form:
+//   // +k8s:deepcopy-gen=package
+//
+// DeepCopy functions can be generated for individual types, rather than the
+// entire package by specifying a comment on the type definion of the form:
+//   // +k8s:deepcopy-gen=true
+//
+// When generating for a whole package, individual types may opt out of
+// DeepCopy generation by specifying a comment on the of the form:
+//   // +k8s:deepcopy-gen=false
+//
+// Note that registration is a whole-package option, and is not available for
+// individual types.
