-      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.

-          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

-          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

-          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.

-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,

-      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.

-![CI](https://github.com/gleam-lang/stdlib/workflows/CI/badge.svg?branch=main)
-
-Gleam's standard library!
-Documentation available on [HexDocs](https://hexdocs.pm/gleam_stdlib/).
-
-## Installation
-
-Add `gleam_stdlib` to your Gleam project.
-
-```sh
-gleam add gleam_stdlib
-```
-
-## Usage
-
-Import the modules you want to use and write some code!
-
-```gleam
-import gleam/string
-
-pub fn greet(name: String) -> String {
-  string.concat(["Hello ", name, "!"])
-}
-```
-
-## Targets
-
-Gleam's standard library supports both targets: Erlang and JavaScript.
-
-### Compatibility
-
-This library is compatible with all versions of Erlang/OTP 26 and higher, 
-as well as all NodeJS, Deno, Bun, and major browsers that are currently
-supported by their maintainers. If you have a compatibility issue with
-any platform open an issue and we'll see what we can do to help.

-//// ## Division by zero
-////
-//// Gleam runs on the Erlang virtual machine, which does not follow the IEEE
-//// 754 standard for floating point arithmetic and does not have an `Infinity`
-//// value.  In Erlang division by zero results in a crash, however Gleam does
-//// not have partial functions and operators in core so instead division by zero
-//// returns zero, a behaviour taken from Pony, Coq, and Lean.
-////
-//// This may seem unexpected at first, but it is no less mathematically valid
-//// than crashing or returning a special value. Division by zero is undefined
-//// in mathematics.

-/// `StringBuilder` is a type used for efficiently building text content to be
