-        or its Contributor Version.
-
-2.2. Effective Date
-
-     The licenses granted in Section 2.1 with respect to any Contribution become
-     effective for each Contribution on the date the Contributor first distributes
-     such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under this
-     License. No additional rights or licenses will be implied from the distribution
-     or licensing of Covered Software under this License. Notwithstanding Section
-     2.1(b) above, no patent license is granted by a Contributor:
-
-     a. for any code that a Contributor has removed from Covered Software; or
-
-     b. for infringements caused by: (i) Your and any other third party’s
-        modifications of Covered Software, or (ii) the combination of its
-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of its
-        Contributions.
-
-     This License does not grant any rights in the trademarks, service marks, or
-     logos of any Contributor (except as may be necessary to comply with the
-     notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this License
-     (see Section 10.2) or under the terms of a Secondary License (if permitted
-     under the terms of Section 3.3).
-
-2.5. Representation
-
-     Each Contributor represents that the Contributor believes its Contributions
-     are its original creation(s) or it has sufficient rights to grant the
-     rights to its Contributions conveyed by this License.
-
-2.6. Fair Use
-
-     This License is not intended to limit any rights You have under applicable
-     copyright doctrines of fair use, fair dealing, or other equivalents.
-
-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under the
-     terms of this License. You must inform recipients that the Source Code Form
-     of the Covered Software is governed by the terms of this License, and how
-     they can obtain a copy of this License. You may not attempt to alter or
-     restrict the recipients’ rights in the Source Code Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this License,
-        or sublicense it under different terms, provided that the license for
-        the Executable Form does not attempt to limit or alter the recipients’
-        rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for the
-     Covered Software. If the Larger Work is a combination of Covered Software
-     with a work governed by one or more Secondary Licenses, and the Covered
-     Software is not Incompatible With Secondary Licenses, this License permits
-     You to additionally distribute such Covered Software under the terms of
-     such Secondary License(s), so that the recipient of the Larger Work may, at
-     their option, further distribute the Covered Software under the terms of
-     either this License or such Secondary License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices (including
-     copyright notices, patent notices, disclaimers of warranty, or limitations
-     of liability) contained within the Source Code Form of the Covered
-     Software, except that You may alter any license notices to the extent
-     required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on behalf
-     of any Contributor. You must make it absolutely clear that any such
-     warranty, support, indemnity, or liability obligation is offered by You
-     alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute, judicial
-   order, or regulation then You must: (a) comply with the terms of this License
-   to the maximum extent possible; and (b) describe the limitations and the code
-   they affect. Such description must be placed in a text file included with all
-   distributions of the Covered Software under this License. Except to the
-   extent prohibited by statute or regulation, such description must be
-   sufficiently detailed for a recipient of ordinary skill to be able to
-   understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
-     if such Contributor fails to notify You of the non-compliance by some
-     reasonable means prior to 60 days after You have come back into compliance.
-     Moreover, Your grants from a particular Contributor are reinstated on an
-     ongoing basis if such Contributor notifies You of the non-compliance by
-     some reasonable means, this is the first time You have received notice of
-     non-compliance with this License from such Contributor, and You become
-     compliant prior to 30 days after Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions, counter-claims,
-     and cross-claims) alleging that a Contributor Version directly or
-     indirectly infringes any patent, then the rights granted to You by any and
-     all Contributors for the Covered Software under Section 2.1 of this License
-     shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an “as is” basis, without
-   warranty of any kind, either expressed, implied, or statutory, including,
-   without limitation, warranties that the Covered Software is free of defects,
-   merchantable, fit for a particular purpose or non-infringing. The entire
-   risk as to the quality and performance of the Covered Software is with You.
-   Should any Covered Software prove defective in any respect, You (not any
-   Contributor) assume the cost of any necessary servicing, repair, or
-   correction. This disclaimer of warranty constitutes an essential part of this
-   License. No use of  any Covered Software is authorized under this License
-   except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from such
-   party’s negligence to the extent applicable law prohibits such limitation.
-   Some jurisdictions do not allow the exclusion or limitation of incidental or
-   consequential damages, so this exclusion and limitation may not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts of
-   a jurisdiction where the defendant maintains its principal place of business
-   and such litigation shall be governed by laws of that jurisdiction, without
-   reference to its conflict-of-law provisions. Nothing in this Section shall
-   prevent a party’s ability to bring cross-claims or counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject matter
-   hereof. If any provision of this License is held to be unenforceable, such
-   provision shall be reformed only to the extent necessary to make it
-   enforceable. Any law or regulation which provides that the language of a
-   contract shall be construed against the drafter shall not be used to construe
-   this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or
-      publish new versions of this License. Each version will be given a
-      distinguishing version number.
-
-10.2. Effect of New Versions
-
-      You may distribute the Covered Software under the terms of the version of
-      the License under which You originally received the Covered Software, or
-      under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-
-      If you create software not governed by this License, and you want to
-      create a new license for such software, you may create and use a modified
-      version of this License if you rename the license and remove any
-      references to the name of the license steward (except to note that such
-      modified license differs from this License).
-
-10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
-      If You choose to distribute Source Code Form that is Incompatible With
-      Secondary Licenses under the terms of this version of the License, the
-      notice described in Exhibit B of this License must be attached.

-# HCL
-
-[![GoDoc](https://godoc.org/github.com/hashicorp/hcl?status.png)](https://godoc.org/github.com/hashicorp/hcl) [![Build Status](https://travis-ci.org/hashicorp/hcl.svg?branch=master)](https://travis-ci.org/hashicorp/hcl)
-
-HCL (HashiCorp Configuration Language) is a configuration language built
-by HashiCorp. The goal of HCL is to build a structured configuration language
-that is both human and machine friendly for use with command-line tools, but
-specifically targeted towards DevOps tools, servers, etc.
-
-HCL is also fully JSON compatible. That is, JSON can be used as completely
-valid input to a system expecting HCL. This helps makes systems
-interoperable with other systems.
-
-HCL is heavily inspired by
-[libucl](https://github.com/vstakhov/libucl),
-nginx configuration, and others similar.
-
-## Why?
-
-A common question when viewing HCL is to ask the question: why not
-JSON, YAML, etc.?
-
-Prior to HCL, the tools we built at [HashiCorp](http://www.hashicorp.com)
-used a variety of configuration languages from full programming languages
-such as Ruby to complete data structure languages such as JSON. What we
-learned is that some people wanted human-friendly configuration languages
-and some people wanted machine-friendly languages.
-
-JSON fits a nice balance in this, but is fairly verbose and most
-importantly doesn't support comments. With YAML, we found that beginners
-had a really hard time determining what the actual structure was, and
-ended up guessing more often than not whether to use a hyphen, colon, etc.
-in order to represent some configuration key.
-
-Full programming languages such as Ruby enable complex behavior
-a configuration language shouldn't usually allow, and also forces
-people to learn some set of Ruby.
-
-Because of this, we decided to create our own configuration language
-that is JSON-compatible. Our configuration language (HCL) is designed
-to be written and modified by humans. The API for HCL allows JSON
-as an input so that it is also machine-friendly (machines can generate
-JSON instead of trying to generate HCL).
-
-Our goal with HCL is not to alienate other configuration languages.
-It is instead to provide HCL as a specialized language for our tools,
-and JSON as the interoperability layer.
-
-## Syntax
-
-For a complete grammar, please see the parser itself. A high-level overview
-of the syntax and grammar is listed here.
-
-  * Single line comments start with `#` or `//`
-
-  * Multi-line comments are wrapped in `/*` and `*/`. Nested block comments
-    are not allowed. A multi-line comment (also known as a block comment)
-    terminates at the first `*/` found.
-
-  * Values are assigned with the syntax `key = value` (whitespace doesn't
-    matter). The value can be any primitive: a string, number, boolean,
-    object, or list.
-
-  * Strings are double-quoted and can contain any UTF-8 characters.
-    Example: `"Hello, World"`
-
-  * Multi-line strings start with `<<EOF` at the end of a line, and end
-    with `EOF` on its own line ([here documents](https://en.wikipedia.org/wiki/Here_document)).
-    Any text may be used in place of `EOF`. Example:
-```
-<<FOO
-hello
-world
-FOO
-```
-
-  * Numbers are assumed to be base 10. If you prefix a number with 0x,
-    it is treated as a hexadecimal. If it is prefixed with 0, it is
-    treated as an octal. Numbers can be in scientific notation: "1e10".
-
-  * Boolean values: `true`, `false`
-
-  * Arrays can be made by wrapping it in `[]`. Example:
-    `["foo", "bar", 42]`. Arrays can contain primitives,
-    other arrays, and objects. As an alternative, lists
-    of objects can be created with repeated blocks, using
-    this structure:
-
-    ```hcl
-    service {
-        key = "value"
-    }
-
-    service {
-        key = "value"
-    }
-    ```
-
-Objects and nested objects are created using the structure shown below:
-
-```
-variable "ami" {
-    description = "the AMI to use"
-}
-```
-This would be equivalent to the following json:
-``` json
-{
-  "variable": {
-      "ami": {
-          "description": "the AMI to use"
-        }
-    }
-}
-```
-
-## Thanks
-
-Thanks to:
-
-  * [@vstakhov](https://github.com/vstakhov) - The original libucl parser
-    and syntax that HCL was based off of.
-
-  * [@fatih](https://github.com/fatih) - The rewritten HCL parser
-    in pure Go (no goyacc) and support for a printer.
