+// conversion-gen is a tool for auto-generating functions that convert
+// between internal and external types.  A general conversion code
+// generation task involves three sets of packages: (1) a set of
+// packages containing internal types, (2) a single package containing
+// the external types, and (3) a single destination package (i.e.,
+// where the generated conversion functions go, and where the
+// developer-authored conversion functions are).  The packages
+// containing the internal types play the role known as "peer
+// packages" in the general code-generation framework of Kubernetes.
+//
+// For each conversion task, `conversion-gen` will generate functions
+// that efficiently convert between same-name types in the two
+// (internal, external) packages.  The generated functions include
+// ones named
+//
+//	autoConvert_<pkg1>_<type>_To_<pkg2>_<type>
+//
+// for each such pair of types --- both with (pkg1,pkg2) =
+// (internal,external) and (pkg1,pkg2) = (external,internal).  The
+// generated conversion functions recurse on the structure of the data
+// types.  For structs, source and destination fields are matched up
+// according to name; if a source field has no corresponding
+// destination or there is a fundamental mismatch in the type of the
+// field then the generated autoConvert_... function has just a
+// warning comment about that field.  The generated conversion
+// functions use standard value assignment wherever possible.  For
+// compound types, the generated conversion functions call the
+// `Convert...` functions for the subsidiary types.
+//
+// For each pair of types `conversion-gen` will also generate a
+// function named
+//
+//	Convert_<pkg1>_<type>_To_<pkg2>_<type>
+//
+// if both of two conditions are met: (1) the destination package does
+// not contain a function of that name in a non-generated file and (2)
+// the generation of the corresponding autoConvert_...  function did
+// not run into trouble with a missing or fundamentally differently
+// typed field.  A generated Convert_... function simply calls the
+// corresponding `autoConvert...` function.  `conversion_gen` also
+// generates a function that updates a given `runtime.Scheme` by
+// registering all the Convert_... functions found and generated.
+// Thus developers can override the generated behavior for selected
+// type pairs by putting the desired Convert_... functions in
+// non-generated files.  Further, developers are practically required
+// to override the generated behavior when there are missing or
+// fundamentally differently typed fields.
+//
+// `conversion-gen` will scan its `--input-dirs`, looking at the
+// package defined in each of those directories for comment tags that
+// define a conversion code generation task.  A package requests
+// conversion code generation by including one or more comment in the
+// package's `doc.go` file (currently anywhere in that file is
+// acceptable, but the recommended location is above the `package`
+// statement), of the form:
+//
+//	// +k8s:conversion-gen=<import-path-of-internal-package>
+//
+// This introduces a conversion task, for which the destination
+// package is the one containing the file with the tag and the tag
+// identifies a package containing internal types.  If there is also a
+// tag of the form
+//
+//	// +k8s:conversion-gen-external-types=<import-path-of-external-package>
+//
+// then it identifies the package containing the external types;
+// otherwise they are in the destination package.
+//
+// For each conversion code generation task, the full set of internal
+// packages (AKA peer packages) consists of the ones specified in the
+// `k8s:conversion-gen` tags PLUS any specified in the
+// `--base-peer-dirs` and `--extra-peer-dirs` flags on the command
+// line.
+//
+// When generating for a package, individual types or fields of structs may opt
+// out of Conversion generation by specifying a comment on the of the form:
+//
+//	// +k8s:conversion-gen=false
