+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      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
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "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.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include

+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

-<p>All the functionality for the crate are exposed through two structs: <code>R2PipeLang</code> and
-<code>R2PipeSpawn</code>. Typically, there are two ways to invoke r2pipe. One by spawning a child-process
-from inside r2 and second by making the program spawn a child r2process.
-<code>enum R2Pipe</code> is provided to allow easier use of the library and abstract the difference between these two methods.
-The <code>macro open_pipe!()</code> determines which of the two methods to use.</p>
-
-<p><strong>Note:</strong> For the second method,
-the path of the executable to be analyzed must be provided, while this is implicit in the first
-method (executable loaded by r2).</p>

+//! `R2Pipe` provides functions to interact with [radare2](http://rada.re/r/).
+//! This aims to be a raw API. For more higher-level functions and structs to abstract
+//! over the generated output, see [r2pipe.rs-frontend]().
+//!
+//! Hence this requires you to have radare2 installed on you system. For more
+//! information refer to the r2 [repository](https://github.com/radare/radare2).
+//! The module spawns an instance of r2 and communicates with it over pipes.
+//! Using commands which produce a JSON output is recommended and easier to
+//! parse.
+//!
+//! `R2Pipe`s are available for a several of languages. For more information
+//! about r2pipes in general head over to the
+//! [wiki](https://github.com/radare/radare2/wiki/R2PipeAPI).
+//!
+//! # Design
+//! All the functionality for the crate are exposed through two structs:
+//! `R2PipeLang` and `R2PipeSpawn`.
+//!
+//! Typically, there are two ways to invoke r2pipe. One by spawning a
+//! child-process
+//! from inside r2 and second by making the program spawn a child r2process.
+//! `enum R2Pipe` is provided to allow easier use of the library and abstract
+//! the
+//! difference between these two methods.
+//!
+//! The `macro open_pipe!()` determines which of the two methods to use.
+//!
+//! **Note:** For the second method,
+//! the path of the executable to be analyzed must be provided, while this is
+//! implicit in the first (pass `None`) method (executable loaded by r2).
+//!
+//! # Example
+//! ```no_run
+//! #[macro_use]
+//! extern crate r2pipe;
+//! extern crate serde_json;
+//! use r2pipe::R2Pipe;
+//! fn main() {
+//!     let path = Some("/bin/ls".to_owned());
+//!     let mut r2p = open_pipe!(path).unwrap();
+//!     println!("{}", r2p.cmd("?e Hello World").unwrap());
+//!     if let Ok(json) = r2p.cmdj("ij") {
+//!         println!("{}", serde_json::to_string_pretty(&json).unwrap());
+//!         println!("ARCH {}", json["bin"]["arch"]);
+//!     }
+//!     r2p.close();
+//! }
+//! ```
+//!
+//! The crate offers various methods to interact with r2pipe, eg. via process (multi-threadable), http or tcp.
+//! Check the examples/ dir for more complete examples.

-<span class='doccomment'>//!</span>
-<span class='doccomment'>//! Hence this requires you to have radare2 installed on you system. For more information please</span>
-<span class='doccomment'>//! refer to the official [radare2 Repository](https://github.com/radare/radare2).</span>
-<span class='doccomment'>//! The module spawns an instance of r2 and communicates with it over pipes. Using commands which</span>
-<span class='doccomment'>//! produce a JSON output is recommended as it is easier to parse.</span>
-<span class='doccomment'>//!</span>
-<span class='doccomment'>//! R2Pipes are available for a several of languages. For more information about r2pipes in general head over to the</span>

-<span class='doccomment'>//! # Design</span>
-<span class='doccomment'>//! All the functionality for the crate are exposed through two structs: `R2PipeLang` and</span>
-<span class='doccomment'>//! `R2PipeSpawn`. Typically, there are two ways to invoke r2pipe. One by spawning a child-process</span>
-<span class='doccomment'>//! from inside r2 and second by making the program spawn a child r2process.</span>
-<span class='doccomment'>//! `enum R2Pipe` is provided to allow easier use of the library and abstract the difference between these two methods.</span>
-<span class='doccomment'>//! The `macro open_pipe!()` determines which of the two methods to use.</span>
-<span class='doccomment'>//!</span>
-<span class='doccomment'>//! **Note:** For the second method,</span>
-<span class='doccomment'>//! the path of the executable to be analyzed must be provided, while this is implicit in the first</span>
-<span class='doccomment'>//! method (executable loaded by r2).</span>
-<span class='doccomment'>//!</span>
-<span class='doccomment'>//! # Example</span>
-<span class='doccomment'>//! ```no_run</span>
