+
+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

+       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

+   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.

+   implied, including, without limitation, any warranties or conditions

+   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,

+   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.

+# rustc_tools_util
+
+A small tool to help you generate version information
+for packages installed from a git repo
+
+## Usage
+
+Add a `build.rs` file to your repo and list it in `Cargo.toml`
+````toml
+build = "build.rs"
+````
+
+List rustc_tools_util as regular AND build dependency.
+````toml
+[dependencies]
+rustc_tools_util = "0.2.1"
+
+[build-dependencies]
+rustc_tools_util = "0.2.1"
+````
+
+In `build.rs`, generate the data in your `main()`
+````rust
+fn main() {
+    println!(
+        "cargo:rustc-env=GIT_HASH={}",
+        rustc_tools_util::get_commit_hash().unwrap_or_default()
+    );
+    println!(
+        "cargo:rustc-env=COMMIT_DATE={}",
+        rustc_tools_util::get_commit_date().unwrap_or_default()
+    );
+    println!(
+        "cargo:rustc-env=RUSTC_RELEASE_CHANNEL={}",
+        rustc_tools_util::get_channel().unwrap_or_default()
+    );
+}
+
+````
+
+Use the version information in your main.rs
+````rust
+use rustc_tools_util::*;
+
+fn show_version() {
+    let version_info = rustc_tools_util::get_version_info!();
+    println!("{}", version_info);
+}
+````
+This gives the following output in clippy:
+`clippy 0.0.212 (a416c5e 2018-12-14)`
