+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# code-generator
+
+Golang code-generators used to implement [Kubernetes-style API types](https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md).
+
+## Purpose
+
+These code-generators can be used
+- in the context of [CustomResourceDefinition](https://kubernetes.io/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/) to build native, versioned clients,
+  informers and other helpers
+- in the context of [User-provider API Servers](https://github.com/kubernetes/apiserver) to build conversions between internal and versioned types, defaulters, protobuf codecs,
+  internal and versioned clients and informers.
+
+## Resources
+- The example [sample controller](https://github.com/kubernetes/sample-controller) shows a code example of a controller that uses the clients, listers and informers generated by this library.
+- The article [Kubernetes Deep Dive: Code Generation for CustomResources](https://blog.openshift.com/kubernetes-deep-dive-code-generation-customresources/) gives a step by step instruction on how to use this library.
+
+## Compatibility
+
+HEAD of this repo will match HEAD of k8s.io/apiserver, k8s.io/apimachinery, and k8s.io/client-go.
+
+## Where does it come from?
+
+`code-generator` is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/code-generator.
+Code changes are made in that location, merged into `k8s.io/kubernetes` and later synced here.

+// 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:

+## Purpose
+
+- `import-boss` enforces import restrictions against all pull requests submitted to the [k/k](https://github.com/kubernetes/kubernetes) repository. There are a number of `.import-restrictions` files that in the [k/k](https://github.com/kubernetes/kubernetes) repository, all of which are defined in `YAML` (or `JSON`) format.
+
+## How does it work?
+
+- When a directory is verified, `import-boss` looks for a file called `.import-restrictions`. If this file is not found, `import-boss` will go up to the parent directory until it finds this `.import-restrictions` file.
+
+- Adding `.import-restrictions` files does not add them to CI runs. They need to be explicitly added to `hack/verify-import-boss.sh`. Once an `.import-restrictions` file is added, all of the sub-packages of this file's directory are added as well.
+
+### What are Rules?
+
+- If an `.import-restrictions` file is found, then all imports of the package are checked against each `rule` in the file. A `rule` consists of three parts:
+  - A `SelectorRegexp`, to select the import paths that the rule applies to.
+  - A list of `AllowedPrefixes`
+  - A list of `ForbiddenPrefixes`
+
+- An import is allowed if it matches at least one allowed prefix and does not match any forbidden prefixes. An example `.import-restrictions` file looks like this:
+
+```json
+{
+  "Rules": [
+    {
+      "SelectorRegexp": "k8s[.]io",
+      "AllowedPrefixes": [
+        "k8s.io/gengo/examples",
+        "k8s.io/kubernetes/third_party"
+      ],
+      "ForbiddenPrefixes": [
+        "k8s.io/kubernetes/pkg/third_party/deprecated"
+      ]
+    },
+    {
+      "SelectorRegexp": "^unsafe$",
+      "AllowedPrefixes": [
+      ],
+      "ForbiddenPrefixes": [
+        ""
+      ]
+    }
+  ]
+}
+```
+- Take note of `"SelectorRegexp": "k8s[.]io"` in the first block. This specifies that we are applying these rules to the `"k8s.io"` import path.
+- The second block explicitly matches the "unsafe" package, and forbids it ("" is a prefix of everything).
+
+### What are Inverse Rules?
+
+- In contrast to non-inverse rules, which are defined in importing packages, inverse rules are defined in imported packages.
+
+- Inverse rules allow for fine-grained import restrictions for "private packages" where we don't want to spread use inside of [kubernetes/kubernetes](https://github.com/kubernetes/kubernetes).
+
+- If an `.import-restrictions` file is found, then all imports of the package are checked against each `inverse rule` in the file. This check will continue, climbing up the directory tree, until a match is found and accepted.
+
+- Inverse rules also have a boolean `transitive` option. When this option is true, the import rule is also applied to `transitive` imports.
+  - `transitive` imports are dependencies not directly depended on by the code, but are needed to run the application. Use this option if you want to apply restrictions to those indirect dependencies.
+
+```yaml
+rules:
+  - selectorRegexp: k8s[.]io
+    allowedPrefixes:
+      - k8s.io/gengo/examples
+      - k8s.io/kubernetes/third_party
+    forbiddenPrefixes:
+      - k8s.io/kubernetes/pkg/third_party/deprecated
+  - selectorRegexp: ^unsafe$
+    forbiddenPrefixes:
+      - ""
+inverseRules:
+  - selectorRegexp: k8s[.]io
+    allowedPrefixes:
+      - k8s.io/same-repo
+      - k8s.io/kubernetes/pkg/legacy
+    forbiddenPrefixes:
+      - k8s.io/kubernetes/pkg/legacy/subpkg
+  - selectorRegexp: k8s[.]io
+    transitive: true
+    forbiddenPrefixes:
+      - k8s.io/kubernetes/cmd/kubelet
+      - k8s.io/kubernetes/cmd/kubectl
+```
+
+## How do I run import-boss within the k/k repo?
+
+- In order to include _test.go files, make sure to pass in the `include-test-files` flag:
+  ```sh
+  hack/verify-import-boss.sh --include-test-files=true
+  ```
+
+- To include other directories, pass in a directory or directories using the `input-dirs` flag:
+  ```sh
+  hack/verify-import-boss.sh --input-dirs="k8s.io/kubernetes/test/e2e/framework/..."
+  ```
+
+## Reference
+
