-
-   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.

-      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

-      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.
-

-# [Google Closure Compiler](https://developers.google.com/closure/compiler/)
-
-[![Build Status](https://travis-ci.org/google/closure-compiler.svg?branch=master)](https://travis-ci.org/google/closure-compiler)
-
-The [Closure Compiler](https://developers.google.com/closure/compiler/) is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.
-
-## Getting Started
- * [Download the latest version](http://dl.google.com/closure-compiler/compiler-latest.zip) ([Release details here](https://github.com/google/closure-compiler/wiki/Releases))
- * [Download a specific version](https://github.com/google/closure-compiler/wiki/Binary-Downloads). Also available via:
-   - [Maven](https://github.com/google/closure-compiler/wiki/Maven)
-   - [NPM](https://www.npmjs.com/package/google-closure-compiler)
- * See the [Google Developers Site](https://developers.google.com/closure/compiler/docs/gettingstarted_app) for documentation including instructions for running the compiler from the command line.
-
-## Options for Getting Help
-1. Post in the [Closure Compiler Discuss Group](https://groups.google.com/forum/#!forum/closure-compiler-discuss)
-2. Ask a question on [Stack Overflow](http://stackoverflow.com/questions/tagged/google-closure-compiler)
-3. Consult the [FAQ](https://github.com/google/closure-compiler/wiki/FAQ)
-
-## Building it Yourself
-
-Note: The Closure Compiler requires [Java 7 or higher](http://www.java.com/).
-
-### Using [Maven](http://maven.apache.org/)
-
-1. Download [Maven](http://maven.apache.org/download.cgi).
-
-2. Add sonatype snapshots repository to `~/.m2/settings.xml`:
-   ```
-   <profile>
-     <id>allow-snapshots</id>
-        <activation><activeByDefault>true</activeByDefault></activation>
-     <repositories>
-       <repository>
-         <id>snapshots-repo</id>
-         <url>https://oss.sonatype.org/content/repositories/snapshots</url>
-         <releases><enabled>false</enabled></releases>
-         <snapshots><enabled>true</enabled></snapshots>
-       </repository>
-     </repositories>
-   </profile>
-   ```
-
-3. Run `mvn -DskipTests` (omit the `-DskipTests` if you want to run all the
-unit tests too).
-
-    This will produce a jar file called `target/closure-compiler-1.0-SNAPSHOT.jar`.
-
-### Using [Eclipse](http://www.eclipse.org/)
-
-1. Download and open the [Eclipse IDE](http://www.eclipse.org/).
-2. Navigate to `File > New > Project ...` and create a Java Project. Give
-   the project a name.
-3. Select `Create project from existing source` and choose the root of the
-   checked-out source tree as the existing directory.
-3. Navigate to the `build.xml` file. You will see all the build rules in
-   the Outline pane. Run the `jar` rule to build the compiler in
-   `build/compiler.jar`.
-
-## Running
-
-On the command line, at the root of this project, type
-
-```
-java -jar build/compiler.jar
-```
-
-This starts the compiler in interactive mode. Type
-
-```javascript
-var x = 17 + 25;
-```
-
-then hit "Enter", then hit "Ctrl-Z" (on Windows) or "Ctrl-D" (on Mac or Linux)
-and "Enter" again. The Compiler will respond:
-
-```javascript
-var x=42;
-```
-
-The Closure Compiler has many options for reading input from a file, writing
-output to a file, checking your code, and running optimizations. To learn more,
-type
-
-```
-java -jar compiler.jar --help
-```
-
-More detailed information about running the Closure Compiler is available in the
-[documentation](http://code.google.com/closure/compiler/docs/gettingstarted_app.html).
-
-## Compiling Multiple Scripts
-
-If you have multiple scripts, you should compile them all together with one
-compile command.
-
-```bash
-java -jar compiler.jar --js_output_file=out.js in1.js in2.js in3.js ...
-```
-
-You can also use minimatch-style globs.
-
-```bash
-# Recursively include all js files in subdirs
-java -jar compiler.jar --js_output_file=out.js 'src/**.js'
-
-# Recursively include all js files in subdirs, excluding test files.
-# Use single-quotes, so that bash doesn't try to expand the '!'
-java -jar compiler.jar --js_output_file=out.js 'src/**.js' '!**_test.js'
-```
-
-The Closure Compiler will concatenate the files in the order they're passed at
-the command line.
-
-If you're using globs or many files, you may start to run into
-problems with managing dependencies between scripts. In this case, you should
-use the [Closure Library](https://developers.google.com/closure/library/). It
-contains functions for enforcing dependencies between scripts, and Closure Compiler
-will re-order the inputs automatically.
-
-## How to Contribute
-### Reporting a bug
-1. First make sure that it is really a bug and not simply the way that Closure Compiler works (especially true for ADVANCED_OPTIMIZATIONS).
- * Check the [official documentation](https://developers.google.com/closure/compiler/)
- * Consult the [FAQ](https://github.com/google/closure-compiler/wiki/FAQ)
- * Search on [Stack Overflow](http://stackoverflow.com/questions/tagged/google-closure-compiler) and in the [Closure Compiler Discuss Group](https://groups.google.com/forum/#!forum/closure-compiler-discuss)
-2. If you still think you have found a bug, make sure someone hasn't already reported it. See the list of [known issues](https://github.com/google/closure-compiler/issues).
-3. If it hasn't been reported yet, post a new issue. Make sure to add enough detail so that the bug can be recreated. The smaller the reproduction code, the better.
-
-### Suggesting a Feature
-1. Consult the [FAQ](https://github.com/google/closure-compiler/wiki/FAQ) to make sure that the behaviour you would like isn't specifically excluded (such as string inlining).
-2. Make sure someone hasn't requested the same thing. See the list of [known issues](https://github.com/google/closure-compiler/issues).
-3. Read up on [what type of feature requests are accepted](https://github.com/google/closure-compiler/wiki/FAQ#how-do-i-submit-a-feature-request-for-a-new-type-of-optimization).
-4. Submit your request as an issue.
-
-### Submitting patches
-1. All contributors must sign a contributor license agreement (CLA).
-   A CLA basically says that you own the rights to any code you contribute,
-   and that you give us permission to use that code in Closure Compiler.
-   You maintain the copyright on that code.
-   If you own all the rights to your code, you can fill out an
-   [individual CLA](http://code.google.com/legal/individual-cla-v1.0.html).
-   If your employer has any rights to your code, then they also need to fill out
-   a [corporate CLA](http://code.google.com/legal/corporate-cla-v1.0.html).
-   If you don't know if your employer has any rights to your code, you should
-   ask before signing anything.
-   By default, anyone with an @google.com email address already has a CLA
-   signed for them.
-2. To make sure your changes are of the type that will be accepted, ask about your patch on the [Closure Compiler Discuss Group](https://groups.google.com/forum/#!forum/closure-compiler-discuss)
-3. Fork the repository.
-4. Make your changes.
-5. Submit a pull request for your changes. A project developer will review your work and then merge your request into the project.
