+          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

+
+      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

+      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.

+# cf-nvidia-tools
+
+This package contains CLI tools for validating and linting NVIDIA's conda recipes on
+conda-forge. The tools are hosted directly in this feedstock; there is no external source
+code repository for these tools at this time.
+
+## API policy
+
+This project will use semantic versioning, and will not have a beta release. In other words,
+it should be safe to pin this tool with an expression like `>=1.0,<2`. Backward incompatible
+changes for any tool in this package will be accompanied by a major version bump. New
+features will increase the minor version. Anything considered a bug fix will be a patch
+release.
+
+## check-glibc
+
+### When to use this tool
+
+The package is binary redistrbution which links to glibc.
+
+### Why is this tool needed
+
+For NVIDIA conda packages which are redists (binary redistributions) there is no compiling
+when building the package, so we do not automatically know if the glibc provided by `{{
+stdlib('c') }}` is new enough for the binaries in the package. If we don't set a new enough
+version for `c_stdlib_version`, end users can get undefined symbol errors. This tool is used
+for checking that a binary redist has correctly specified the `c_stdlib_version` variable in
+the recipe.
+
+### How to Use
+
+Use the tool in the build script after installing the binaries to `$PREFIX`. For example:
+
+```bash
+check-glibc $PREFIX/lib/libfoo*.so.*
+```
+
+Here we have used bash to expand a glob expression and provide `check-glibc` with a list of
+files to search for glibc symbols. You can check arbitrary files by setting your own glob
+expression or explicitly listing the files. We have narrowed the glob to versioned shared
+libraries only because we don't need to check links to shared libraries (that would be
+duplicate effort).
+
+> [!CAUTION]
+> check-glibc does not expand glob expressions. You must leave the glob expression unquoted
+> in order for bash to expand the expression before check-glibc is called.
+
+> [!CAUTION]
+> check-glibc will ignore links. In other words, you must name the *actual files* not
+> symbolic links.
+
+The tool will exit with status 1 if `c_stdlib_version` is older than newest symbol detected
+in any of the binaries. The newest symbol detected for each binary is logged to the
+terminal.
+
+If this check fails, increase `c_stdlib_version` to a version newer than the version
+detected by this tool.
