-# How To Contribute
-
-Want to contribute? Great! First, read this page (including the small print at the end).
-
-### Before you contribute
-Before we can use your code, you must sign the
-[Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual?csw=1)
-(CLA), which you can do online. The CLA is necessary mainly because you own the
-copyright to your changes, even after your contribution becomes part of our
-codebase, so we need your permission to use and distribute your code. We also
-need to be sure of various other things—for instance that you'll tell us if you
-know that your code infringes on other people's patents. You don't have to sign
-the CLA until after you've submitted your code for review and a member has
-approved it, but you must do it before we can put your code into our codebase.
-Before you start working on a larger contribution, you should get in touch with
-us first through the issue tracker with your idea so that we can help out and
-possibly guide you. Coordinating up front makes it much easier to avoid
-frustration later on.
-
-### Code reviews
-All submissions, including submissions by project members, require review. We
-use Github pull requests for this purpose.
-
-### The small print
-Contributions made by corporations are covered by a different agreement than
-the one above, the Software Grant and Corporate Contributor License Agreement.

-          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,

-      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.

-# Subpar
-
-Subpar is a utility for creating self-contained python executables.  It is
-designed to work well with [Bazel](http://bazel.io).
-
-## Setup
-
-* Add the following to your WORKSPACE file:
-
-```python
-git_repository(
-    name = "subpar",
-    remote = "TODO",
-    commit = "HEAD",
-)
-```
-
-* Add the following to the top of any BUILD files that declare `par_binary()`
-  rules:
-
-```python
-load("@subpar//:subpar.bzl", "par_binary")
-```
-
-## Usage
-
-`par_binary()` is a drop-in replacement for `py_binary()` that also builds a
-self-contained, single-file executable for the application, with a `.par` file
-extension.
-
-The .par file is created alongside the python stub and .runfiles
-directories that py_binary() creates, but is independent of them.
-It can be copied to other directories or machines, and executed
-directly without needing the .runfiles directory.  The body of the
-.par file contains all the srcs, deps, and data files listed.
-
-## Limitations:
-
-* C extension modules in 'deps' is not yet supported
-* Automatic re-extraction of '.runfiles' is not yet supported
-* Python 3 is not yet supported
-* Does not include a copy of the Python interpreter ('hermetic .par')
-
-## Example
-
-```python
-par_binary(
-    name = 'foo',
-    srcs = ['foo.py', 'bar.py'],
-    deps = ['//baz:some_py_lib'],
-    data = ['quux.dat'],
-)
-```
-
-This results in the following files being created by bazel build:
-
-```
-bazel-bin/
-    package/
-        foo
-        foo.par
-        foo.runfiles/
-            ...
-```
-
-The .par file can be copied, moved, or renamed, and still run like a
-compiled executable file:
-
-```
-$ scp bazel-bin/package/foo.par my-other-machine:foo.par
-$ ssh my-other-machine ./foo.par
-```
-
-## System Requirements
-
-* Python Versions: CPython versions 2.7.6+
-* Operating Systems: Debian-derived Linux, including Ubuntu and Goobuntu.
-
-# DISCLAIMER
-
-This is not an official Google product, it is just code that happens
-to be owned by Google.
