+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS

+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).

+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.

+   transformation or translation of a Source form, including but
+   not limited to compiled object code, generated documentation,
+   and conversions to other media types.
+
+   "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
+   the original version of the Work and any modifications or additions
+   to that Work or Derivative Works thereof, that is intentionally

+   the copyright owner. For the purposes of this definition, "submitted"
+   means any form of electronic, verbal, or written communication sent
+   to the Licensor or its representatives, including but not limited to
+   communication on electronic mailing lists, source code control systems,
+   and issue tracking systems that are managed by, or on behalf of, the

+
+   "Contributor" shall mean Licensor and any individual or Legal Entity
+   on behalf of whom a Contribution has been received by Licensor and
+   subsequently incorporated within the Work.
+
+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.
+
+END OF TERMS AND CONDITIONS
+
+APPENDIX: How to apply the Apache License to your work.

+<span class="doccomment">/// An asynchronous function from a `Request` to a `Response`.</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// The `Service` trait is a simplified interface making it easy to write</span>
+<span class="doccomment">/// network applications in a modular and reusable way, decoupled from the</span>
+<span class="doccomment">/// underlying protocol. It is one of Tower&#39;s fundamental abstractions.</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// # Functional</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// A `Service` is a function of a `Request`. It immediately returns a</span>
+<span class="doccomment">/// `Future` representing the eventual completion of processing the</span>
+<span class="doccomment">/// request. The actual request processing may happen at any time in the</span>
+<span class="doccomment">/// future, on any thread or executor. The processing may depend on calling</span>
+<span class="doccomment">/// other services. At some point in the future, the processing will complete,</span>
+<span class="doccomment">/// and the `Future` will resolve to a response or error.</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// At a high level, the `Service::call` function represents an RPC request. The</span>
+<span class="doccomment">/// `Service` value can be a server or a client.</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// # Server</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// An RPC server *implements* the `Service` trait. Requests received by the</span>
+<span class="doccomment">/// server over the network are deserialized and then passed as an argument to the</span>
+<span class="doccomment">/// server value. The returned response is sent back over the network.</span>
+<span class="doccomment">///</span>
+<span class="doccomment">/// As an example, here is how an HTTP request is processed by a server:</span>

+<p>In the above example, the buffer layer receives the request first followed
+by <code>concurrency_limit</code>. <code>buffer</code> enables up to 100 request to be in-flight
+<strong>on top of</strong> the requests that have already been forwarded to the next
+layer. Combined with <code>concurrency_limit</code>, this allows up to 110 requests to be
+in-flight.</p>

+<p><code>ServiceBuilder</code> provides a <a href="https://doc.rust-lang.org/1.0.0/style/ownership/builders.html">builder-like interface</a> for composing
+layers to be applied to a <code>Service</code>.</p>
+<h1 id="service" class="section-header"><a href="#service">Service</a></h1>
+<p>A <a href="tower_service::Service"><code>Service</code></a> is a trait representing an
+asynchronous function of a request to a response. It is similar to <code>async fn(Request) -&gt; Result&lt;Response, Error&gt;</code>.</p>
+<p>A <code>Service</code> is typically bound to a single transport, such as a TCP
+connection.  It defines how <em>all</em> inbound or outbound requests are handled
+by that connection.</p>
+<h1 id="order" class="section-header"><a href="#order">Order</a></h1>
+<p>The order in which layers are added impacts how requests are handled. Layers
+that are added first will be called with the request first. The argument to
+<code>service</code> will be last to see the request.</p>
+
+<div class="example-wrap"><pre class="rust rust-example-rendered">
+<span class="attribute">#[<span class="ident">cfg</span>(<span class="ident">all</span>(<span class="ident">feature</span> <span class="op">=</span> <span class="string">&quot;buffer&quot;</span>, <span class="ident">feature</span> <span class="op">=</span> <span class="string">&quot;limit&quot;</span>))]</span>

+    .<span class="ident">service</span>(<span class="ident">svc</span>)</pre></div>
+<p>In the above example, the buffer layer receives the request first followed
+by <code>concurrency_limit</code>. <code>buffer</code> enables up to 100 request to be in-flight
+<strong>on top of</strong> the requests that have already been forwarded to the next
+layer. Combined with <code>concurrency_limit</code>, this allows up to 110 requests to be
+in-flight.</p>
+
+<div class="example-wrap"><pre class="rust rust-example-rendered">

+<p>The above example is similar, but the order of layers is reversed. Now,
