+   "Work" shall mean the work of authorship, whether in Source or
+   Object form, made available under the License, as indicated by a
+   copyright notice that is included in or attached to the work
+   (an example is provided in the Appendix below).
+
+   "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
+   separable from, or merely link (or bind by name) to the interfaces of,
+   the Work and Derivative Works thereof.
+
+   "Contribution" shall mean any work of authorship, including

+
+   "Contributor" shall mean Licensor and any individual or Legal Entity
+   on behalf of whom a Contribution has been received by Licensor and

+
+2. Grant of Copyright License. Subject to the terms and conditions of
+   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,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,
+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   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:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (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.

+
+* [Crate](https://crates.io/crates/crc)
+* [Documentation](https://docs.rs/crc/)
+* [Usage](#usage)
+* [Benchmark](#benchmark)
+* [License](#license)
+
+## Usage
+Add `crc` to `Cargo.toml`
+```toml
+[dependencies]
+crc = "^1.0.0"
+```
+or
+```toml
+[dependencies.crc]
+git = "https://github.com/mrhooray/crc-rs"
+```
+
+Add this to crate root
+```rust
+extern crate crc;
+```
+
+### Compute CRC16
+```rust
+use crc::{crc16, Hasher16};
+
+assert_eq!(crc16::checksum_x25(b"123456789"), 0x906e);
+assert_eq!(crc16::checksum_usb(b"123456789"), 0xb4c8);
+
+// use provided or custom polynomial
+let mut digest = crc16::Digest::new(crc16::X25);
+digest.write(b"123456789");
+assert_eq!(digest.sum16(), 0x906e);
+
+// with initial
+let mut digest = crc16::Digest::new_with_initial(crc16::X25, 0u16);
+digest.write(b"123456789");
+assert_eq!(digest.sum16(), 0x906e);
+```
+
+### Compute CRC32
+```rust
+use crc::{crc32, Hasher32};
+
+// CRC-32-IEEE being the most commonly used one
+assert_eq!(crc32::checksum_ieee(b"123456789"), 0xcbf43926);
+assert_eq!(crc32::checksum_castagnoli(b"123456789"), 0xe3069283);
+assert_eq!(crc32::checksum_koopman(b"123456789"), 0x2d3dd0ae);
+
+// use provided or custom polynomial
+let mut digest = crc32::Digest::new(crc32::IEEE);
+digest.write(b"123456789");
+assert_eq!(digest.sum32(), 0xcbf43926);
+
+// with initial
+let mut digest = crc32::Digest::new_with_initial(crc32::IEEE, 0u32);
+digest.write(b"123456789");
+assert_eq!(digest.sum32(), 0xcbf43926);
+```
+
+### Compute CRC64
+```rust
+use crc::{crc64, Hasher64};
+
+assert_eq!(crc64::checksum_ecma(b"123456789"), 0x995dc9bbdf1939fa);
+assert_eq!(crc64::checksum_iso(b"123456789"), 0xb90956c775a41001);
+
+// use provided or custom polynomial
+let mut digest = crc64::Digest::new(crc64::ECMA);
+digest.write(b"123456789");
+assert_eq!(digest.sum64(), 0x995dc9bbdf1939fa);
+
+// with initial
+let mut digest = crc64::Digest::new_with_initial(crc64::ECMA, 0u64);
+digest.write(b"123456789");
+assert_eq!(digest.sum64(), 0x995dc9bbdf1939fa);
+```

+//! ### Compute CRC16
+//! ```rust

+//!
+//! assert_eq!(crc16::checksum_x25(b"123456789"), 0x906e);

+//! ### Compute CRC32
+//! ```rust
