-Contributing to Paho
-====================
-
-Thanks for your interest in this project.
-
-Project description:
---------------------
-
-The Paho project has been created to provide scalable open-source implementations of open and standard messaging protocols aimed at new, existing, and emerging applications for Machine-to-Machine (M2M) and Internet of Things (IoT).
-Paho reflects the inherent physical and cost constraints of device connectivity. Its objectives include effective levels of decoupling between devices and applications, designed to keep markets open and encourage the rapid growth of scalable Web and Enterprise middleware and applications. Paho is being kicked off with MQTT publish/subscribe client implementations for use on embedded platforms, along with corresponding server support as determined by the community.

-Eclipse Public License - v 1.0
-
-THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
-
-1. DEFINITIONS
-
-"Contribution" means:
-
-a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and
-
-b) in the case of each subsequent Contributor:
-
-i) changes to the Program, and
-
-ii) additions to the Program;
-
-where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
-
-"Contributor" means any person or entity that distributes the Program.
-
-"Licensed Patents" mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
-
-"Program" means the Contributions distributed in accordance with this Agreement.
-
-"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
-
-2. GRANT OF RIGHTS
-
-a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.
-
-b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.
-
-c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.
-
-d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
-
-3. REQUIREMENTS
-
-A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:
-
-a) it complies with the terms and conditions of this Agreement; and
-
-b) its license agreement:
-
-i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
-
-ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
-
-iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
-
-iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
-
-When the Program is made available in source code form:
-
-a) it must be made available under this Agreement; and
-
-b) a copy of this Agreement must be included with each copy of the Program.
-
-Contributors may not remove or alter any copyright notices contained within the Program.
-
-Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.
-
-For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED 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. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.
-
-Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
-
-This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.

-Eclipse Paho MQTT Go client
-===========================
-
-
-This repository contains the source code for the [Eclipse Paho](http://eclipse.org/paho) MQTT Go client library.
-
-This code builds a library which enable applications to connect to an [MQTT](http://mqtt.org) broker to publish messages, and to subscribe to topics and receive published messages.
-
-This library supports a fully asynchronous mode of operation.
-
-
-Installation and Build
-----------------------
-
-This client is designed to work with the standard Go tools, so installation is as easy as:
-
-```
-go get github.com/eclipse/paho.mqtt.golang
-```
-
-The client depends on Google's [websockets](https://godoc.org/golang.org/x/net/websocket) and [proxy](https://godoc.org/golang.org/x/net/proxy) package,
-also easily installed with the commands:
-
-```
-go get golang.org/x/net/websocket
-go get golang.org/x/net/proxy
-```
-
-
-Usage and API
--------------
-
-Detailed API documentation is available by using to godoc tool, or can be browsed online
-using the [godoc.org](http://godoc.org/github.com/eclipse/paho.mqtt.golang) service.
-
-Make use of the library by importing it in your Go client source code. For example,
-```
-import "github.com/eclipse/paho.mqtt.golang"
-```
-
-Samples are available in the `cmd` directory for reference.
-
-
-Runtime tracing
----------------
-
-Tracing is enabled by assigning logs (from the Go log package) to the logging endpoints, ERROR, CRITICAL, WARN and DEBUG
-
-
-Reporting bugs
---------------
-
-Please report bugs by raising issues for this project in github https://github.com/eclipse/paho.mqtt.golang/issues
-
-
-More information
-----------------
-
-Discussion of the Paho clients takes place on the [Eclipse paho-dev mailing list](https://dev.eclipse.org/mailman/listinfo/paho-dev).
-
-General questions about the MQTT protocol are discussed in the [MQTT Google Group](https://groups.google.com/forum/?hl=en-US&fromgroups#!forum/mqtt).
-
-There is much more information available via the [MQTT community site](http://mqtt.org).

-// Client is the interface definition for a Client as used by this
-// library, the interface is primarily to allow mocking tests.
-//
-// It is an MQTT v3.1.1 client for communicating
-// with an MQTT server using non-blocking methods that allow work
-// to be done in the background.
-// An application may connect to an MQTT server using:
-// A plain TCP socket
-// A secure SSL/TLS socket
-// A websocket
-// To enable ensured message delivery at Quality of Service (QoS) levels
-// described in the MQTT spec, a message persistence mechanism must be
-// used. This is done by providing a type which implements the Store
-// interface. For convenience, FileStore and MemoryStore are provided
-// implementations that should be sufficient for most use cases. More
-// information can be found in their respective documentation.
-// Numerous connection options may be specified by configuring a
-// and then supplying a ClientOptions type.

-Eclipse Public License - v 1.0
-
-THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
-
-1. DEFINITIONS
-
-"Contribution" means:
-
-a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and
-b) in the case of each subsequent Contributor:
-i) changes to the Program, and
-ii) additions to the Program;
-where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
-"Contributor" means any person or entity that distributes the Program.
-
-"Licensed Patents" mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
-
-"Program" means the Contributions distributed in accordance with this Agreement.
-
-"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
-
-2. GRANT OF RIGHTS
-
-a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.
-b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.
-c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.
-d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
-3. REQUIREMENTS
-
-A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:
-
-a) it complies with the terms and conditions of this Agreement; and
-b) its license agreement:
-i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
-ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
-iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
-iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
-When the Program is made available in source code form:
-
-a) it must be made available under this Agreement; and
-b) a copy of this Agreement must be included with each copy of the Program.
-Contributors may not remove or alter any copyright notices contained within the Program.
-
-Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.
-
-For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED 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. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.
-
-Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
-
-This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.

-
-Usage Of Content
-
-THE ECLIPSE FOUNDATION MAKES AVAILABLE SOFTWARE, DOCUMENTATION, INFORMATION AND/OR OTHER MATERIALS FOR OPEN SOURCE PROJECTS
- (COLLECTIVELY "CONTENT"). USE OF THE CONTENT IS GOVERNED BY THE TERMS AND CONDITIONS OF THIS AGREEMENT AND/OR THE TERMS AND
- CONDITIONS OF LICENSE AGREEMENTS OR NOTICES INDICATED OR REFERENCED BELOW. BY USING THE CONTENT, YOU AGREE THAT YOUR USE
- OF THE CONTENT IS GOVERNED BY THIS AGREEMENT AND/OR THE TERMS AND CONDITIONS OF ANY APPLICABLE LICENSE AGREEMENTS OR
- NOTICES INDICATED OR REFERENCED BELOW. IF YOU DO NOT AGREE TO THE TERMS AND CONDITIONS OF THIS AGREEMENT AND THE TERMS AND
- CONDITIONS OF ANY APPLICABLE LICENSE AGREEMENTS OR NOTICES INDICATED OR REFERENCED BELOW, THEN YOU MAY NOT USE THE CONTENT.
-
-Applicable Licenses
-
-Unless otherwise indicated, all Content made available by the Eclipse Foundation is provided to you under the terms and conditions of the Eclipse Public License Version 1.0
- ("EPL"). A copy of the EPL is provided with this Content and is also available at http://www.eclipse.org/legal/epl-v10.html .
- For purposes of the EPL, "Program" will mean the Content.
-
-Content includes, but is not limited to, source code, object code, documentation and other files maintained in the Eclipse Foundation source code
- repository ("Repository") in software modules ("Modules") and made available as downloadable archives ("Downloads").
-
-
- Content may be structured and packaged into modules to facilitate delivering, extending, and upgrading the Content. Typical modules may include plug-ins ("Plug-ins"), plug-in fragments ("Fragments"), and features ("Features").
- Each Plug-in or Fragment may be packaged as a sub-directory or JAR (Java™ ARchive) in a directory named "plugins".
- A Feature is a bundle of one or more Plug-ins and/or Fragments and associated material. Each Feature may be packaged as a sub-directory in a directory named "features". Within a Feature, files named "feature.xml" may contain a list of the names and version numbers of the Plug-ins
- and/or Fragments associated with that Feature.
- Features may also include other Features ("Included Features"). Within a Feature, files named "feature.xml" may contain a list of the names and version numbers of Included Features.
-
-
-The terms and conditions governing Plug-ins and Fragments should be contained in files named "about.html" ("Abouts"). The terms and conditions governing Features and
-Included Features should be contained in files named "license.html" ("Feature Licenses"). Abouts and Feature Licenses may be located in any directory of a Download or Module
-including, but not limited to the following locations:
-
-
- The top-level (root) directory
- Plug-in and Fragment directories
- Inside Plug-ins and Fragments packaged as JARs
- Sub-directories of the directory named "src" of certain Plug-ins
- Feature directories
-
-
-Note: if a Feature made available by the Eclipse Foundation is installed using the Provisioning Technology (as defined below), you must agree to a license ("Feature Update License") during the
-installation process. If the Feature contains Included Features, the Feature Update License should either provide you with the terms and conditions governing the Included Features or
-inform you where you can locate them. Feature Update Licenses may be found in the "license" property of files named "feature.properties" found within a Feature.
-Such Abouts, Feature Licenses, and Feature Update Licenses contain the terms and conditions (or references to such terms and conditions) that govern your use of the associated Content in
-that directory.
-
-THE ABOUTS, FEATURE LICENSES, AND FEATURE UPDATE LICENSES MAY REFER TO THE EPL OR OTHER LICENSE AGREEMENTS, NOTICES OR TERMS AND CONDITIONS. SOME OF THESE
-OTHER LICENSE AGREEMENTS MAY INCLUDE (BUT ARE NOT LIMITED TO):
-
-
-
-IT IS YOUR OBLIGATION TO READ AND ACCEPT ALL SUCH TERMS AND CONDITIONS PRIOR TO USE OF THE CONTENT. If no About, Feature License, or Feature Update License is provided, please
-contact the Eclipse Foundation to determine what terms and conditions govern that particular Content.
-
-
-Use of Provisioning Technology
-
-The Eclipse Foundation makes available provisioning software, examples of which include, but are not limited to, p2 and the Eclipse
- Update Manager ("Provisioning Technology") for the purpose of allowing users to install software, documentation, information and/or
- other materials (collectively "Installable Software"). This capability is provided with the intent of allowing such users to
- install, extend and update Eclipse-based products. Information about packaging Installable Software is available at http://eclipse.org/equinox/p2/repository_packaging.html
- ("Specification").
-
-You may use Provisioning Technology to allow other parties to install Installable Software. You shall be responsible for enabling the
- applicable license agreements relating to the Installable Software to be presented to, and accepted by, the users of the Provisioning Technology
- in accordance with the Specification. By using Provisioning Technology in such a manner and making it available in accordance with the
- Specification, you further acknowledge your agreement to, and the acquisition of all necessary rights to permit the following:
-
-
- A series of actions may occur ("Provisioning Process") in which a user may execute the Provisioning Technology
- on a machine ("Target Machine") with the intent of installing, extending or updating the functionality of an Eclipse-based
- product.
- During the Provisioning Process, the Provisioning Technology may cause third party Installable Software or a portion thereof to be
- accessed and copied to the Target Machine.
- Pursuant to the Specification, you will provide to the user the terms and conditions that govern the use of the Installable
- Software ("Installable Software Agreement") and such Installable Software Agreement shall be accessed from the Target
- Machine in accordance with the Specification. Such Installable Software Agreement must inform the user of the terms and conditions that govern
- the Installable Software and must solicit acceptance by the end user in the manner prescribed in such Installable Software Agreement. Upon such
- indication of agreement by the user, the provisioning Technology will complete installation of the Installable Software.

-====
-
-Leveled execution logs for Go.
-
-This is an efficient pure Go implementation of leveled logs in the
-manner of the open source C++ package
- https://github.com/google/glog
-
-By binding methods to booleans it is possible to use the log package
-without paying the expense of evaluating the arguments to the log.
-Through the -vmodule flag, the package also provides fine-grained
-control over logging at the file level.
-
-The comment from glog.go introduces the ideas:
-
- Package glog implements logging analogous to the Google-internal
- C++ INFO/ERROR/V setup. It provides functions Info, Warning,
- Error, Fatal, plus formatting variants such as Infof. It
- also provides V-style logging controlled by the -v and
- -vmodule=file=2 flags.
-
- Basic examples:
-
- glog.Info("Prepare to repel boarders")
-
- glog.Fatalf("Initialization failed: %s", err)
-
- See the documentation for the V function for an explanation
- of these examples:
-
- if glog.V(2) {
- glog.Info("Starting transaction...")
- }
-
- glog.V(2).Infoln("Processed", nItems, "elements")
-
-
-The repository contains an open source version of the log package
-used inside Google. The master copy of the source lives inside
-Google, not here. The code in this repo is for export only and is not itself
-under development. Feature requests will be ignored.
-
-Send bug reports to golang-nuts@googlegroups.com.

-// present.)
-// -v=0
-// Enable V-leveled logging at the specified level.
-// -vmodule=""
-// The syntax of the argument is a comma-separated list of pattern=N,
-// where pattern is a literal file name (minus the ".go" suffix) or
-// "glob" pattern and N is a V level. For instance,
-// -vmodule=gopher*=3

-go-rpio
-=======
-
-Native GPIO-Gophers for your Pi!
-
-**Documentation:** [](https://godoc.org/github.com/stianeikeland/go-rpio)
-
-go-rpio is a Go library for accessing [GPIO](http://elinux.org/Rpi_Low-level_peripherals)-pins
-on the [Raspberry Pi](https://en.wikipedia.org/wiki/Raspberry_Pi).
-
-It requires no external c libraries such as
-[WiringPI](https://projects.drogon.net/raspberry-pi/wiringpi/) or [bcm2835](http://www.open.com.au/mikem/bcm2835).
-
-There's a tiny bit of additional information over at my [blog](https://blog.eikeland.se/2013/07/30/go-gpio-library-for-raspberry-pi/).
-
-
-
-## Releases ##
-- 1.0.0 - Supports original rpi A/B/B+
-- 2.0.0 - Adds support for rpi 2, by @akramer
-- 3.0.0 - Adds support for /dev/gpiomem, by @dotdoom
-- 4.0.0 - Adds support for PWM and Clock modes, by @Drahoslav7
-- 4.1.0 - Adds support for edge detection, by @Drahoslav7
-- 4.2.0 - Faster write and toggle of output pins, by @Drahoslav7
-
-## Usage ##
-
-```go
-import "github.com/stianeikeland/go-rpio"
-```
-
-Open memory range for GPIO access in /dev/mem
-
-```go
-err := rpio.Open()
-```
-
-Initialize a pin, run basic operations.
-Pin refers to the bcm2835 pin, not the physical pin on the raspberry pi header. Pin 10 here is exposed on the pin header as physical pin 19.
-
-```go
-pin := rpio.Pin(10)
-
-pin.Output() // Output mode
-pin.High() // Set pin High
-pin.Low() // Set pin Low
-pin.Toggle() // Toggle pin (Low -> High -> Low)
-
-pin.Input() // Input mode
-res := pin.Read() // Read state from pin (High / Low)
-
-pin.Mode(rpio.Output) // Alternative syntax
-pin.Write(rpio.High) // Alternative syntax
-```
-
-Pull up/down/off can be set using:
-
-```go
-pin.PullUp()
-pin.PullDown()
-pin.PullOff()
-
-pin.Pull(rpio.PullUp)
-```
-
-Unmap memory when done
-
-```go
-rpio.Close()
-```
-
-Also see example [examples/blinker/blinker.go](examples/blinker/blinker.go)
-
-## Other ##
-
-Currently, it supports basic functionality such as:
-- Pin Direction (Input / Output)
-- Write (High / Low)
-- Read (High / Low)
-- Pull (Up / Down / Off)
-- PWM (hardware, on supported pins)
-- Clock
-- Edge detection
-
-It works by memory-mapping the bcm2835 gpio range, and therefore require root/administrative-rights to run.
-
-## Using without root ##
-
-This library can utilize the new [/dev/gpiomem](https://github.com/raspberrypi/linux/pull/1112/files)
-memory range if available.
-
-You will probably need to upgrade to the latest kernel (or wait for the next raspbian release) if you're missing /dev/gpiomem. You will also need to add a `gpio` group, add your user to the group, and then set up udev rules. I would recommend using [create_gpio_user_permissions.py](https://github.com/waveform80/rpi-gpio/blob/master/create_gpio_user_permissions.py) if you're unsure how to do this.
-
-PWM modes will still require root.

-Package rpio provides GPIO access on the Raspberry PI without any need
-for external c libraries (eg. WiringPi or BCM2835).
-
-Supports simple operations such as:
- - Pin mode/direction (input/output/clock/pwm)
- - Pin write (high/low)
- - Pin read (high/low)
- - Pin edge detection (no/rise/fall/any)
- - Pull up/down/off
-And clock/pwm related oparations:
- - Set Clock frequency
- - Set Duty cycle
-
-Example of use:
-
- rpio.Open()
- defer rpio.Close()
-
- pin := rpio.Pin(4)
- pin.Output()
-
- for {
- pin.Toggle()
- time.Sleep(time.Second)
- }
-
-The library use the raw BCM2835 pinouts, not the ports as they are mapped
-on the output pins for the raspberry pi, and not the wiringPi convention.

-# YAML support for the Go language
-
-Introduction
-------------
-
-The yaml package enables Go programs to comfortably encode and decode YAML
-values. It was developed within [Canonical](https://www.canonical.com) as
-part of the [juju](https://juju.ubuntu.com) project, and is based on a
-pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
-C library to parse and generate YAML data quickly and reliably.
-
-Compatibility
--------------
-
-The yaml package supports most of YAML 1.1 and 1.2, including support for
-anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
-implemented, and base-60 floats from YAML 1.1 are purposefully not
-supported since they're a poor design and are gone in YAML 1.2.
-
-Installation and usage
-----------------------
-
-The import path for the package is *gopkg.in/yaml.v2*.
-
-To install it, run:
-
- go get gopkg.in/yaml.v2
-
-API documentation
------------------
-
-If opened in a browser, the import path itself leads to the API documentation:
-
- * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2)
-
-API stability
--------------
-
-The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).
-
-
-License
--------
-
-The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
-
-
-Example
--------
-
-```Go
-package main
-
-import (
- "fmt"
- "log"
-
- "gopkg.in/yaml.v2"
-)
-
-var data = `
-a: Easy!
-b:
- c: 2
- d: [3, 4]
-`
-
-// Note: struct fields must be public in order for unmarshal to
-// correctly populate the data.
-type T struct {
- A string
- B struct {
- RenamedC int `yaml:"c"`
- D []int `yaml:",flow"`
- }
-}
-
-func main() {
- t := T{}
-
- err := yaml.Unmarshal([]byte(data), &t)
- if err != nil {
- log.Fatalf("error: %v", err)
- }
- fmt.Printf("--- t:\n%v\n\n", t)
-
- d, err := yaml.Marshal(&t)
- if err != nil {
- log.Fatalf("error: %v", err)
- }
- fmt.Printf("--- t dump:\n%s\n\n", string(d))
-
- m := make(map[interface{}]interface{})
-
- err = yaml.Unmarshal([]byte(data), &m)
- if err != nil {
- log.Fatalf("error: %v", err)
- }
- fmt.Printf("--- m:\n%v\n\n", m)
-
- d, err = yaml.Marshal(&m)
- if err != nil {
- log.Fatalf("error: %v", err)
- }
- fmt.Printf("--- m dump:\n%s\n\n", string(d))
-}
-```
-
-This example will generate the following output:
-
-```
---- t:
-{Easy! {2 [3 4]}}
-
---- t dump:
-a: Easy!
-b:
- c: 2
- d: [3, 4]
-
-
---- m:
-map[a:Easy! b:map[c:2 d:[3 4]]]
-
---- m dump:
-a: Easy!
-b:
- c: 2
- d:
- - 3
- - 4
-```

-// Introduction
-// ************
-//
-// The following notes assume that you are familiar with the YAML specification
-// (http://yaml.org/spec/1.2/spec.html). We mostly follow it, although in
-// some cases we are less restrictive that it requires.
-//
-// The process of transforming a YAML stream into a sequence of events is
-// divided on two steps: Scanning and Parsing.
-//
-// The Scanner transforms the input stream into a sequence of tokens, while the
-// parser transform the sequence of tokens produced by the Scanner into a
-// sequence of parsing events.
-//
-// The Scanner is rather clever and complicated. The Parser, on the contrary,
-// is a straightforward implementation of a recursive-descendant parser (or,
-// LL(1) parser, as it is usually called).
-//
-// Actually there are two issues of Scanning that might be called "clever", the
-// rest is quite straightforward. The issues are "block collection start" and
-// "simple keys". Both issues are explained below in details.
-//
-// Here the Scanning step is explained and implemented. We start with the list
-// of all the tokens produced by the Scanner together with short descriptions.
-//
-// Now, tokens:
-//
-// STREAM-START(encoding) # The stream start.
-// STREAM-END # The stream end.
-// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive.
-// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive.
-// DOCUMENT-START # '---'
-// DOCUMENT-END # '...'
-// BLOCK-SEQUENCE-START # Indentation increase denoting a block
-// BLOCK-MAPPING-START # sequence or a block mapping.
-// BLOCK-END # Indentation decrease.
-// FLOW-SEQUENCE-START # '['
-// FLOW-SEQUENCE-END # ']'
-// BLOCK-SEQUENCE-START # '{'
-// BLOCK-SEQUENCE-END # '}'
-// BLOCK-ENTRY # '-'
-// FLOW-ENTRY # ','
-// KEY # '?' or nothing (simple keys).
-// VALUE # ':'
-// ALIAS(anchor) # '*anchor'
-// ANCHOR(anchor) # '&anchor'
-// TAG(handle,suffix) # '!handle!suffix'
-// SCALAR(value,style) # A scalar.
-//
-// The following two tokens are "virtual" tokens denoting the beginning and the
-// end of the stream:
-//
-// STREAM-START(encoding)
-// STREAM-END
-//
-// We pass the information about the input stream encoding with the
-// STREAM-START token.
-//
-// The next two tokens are responsible for tags:
-//
-// VERSION-DIRECTIVE(major,minor)
-// TAG-DIRECTIVE(handle,prefix)
-//
-// Example:
-//
-// %YAML 1.1
-// %TAG ! !foo
-// %TAG !yaml! tag:yaml.org,2002:
-// ---
-//
-// The correspoding sequence of tokens:
-//
-// STREAM-START(utf-8)
-// VERSION-DIRECTIVE(1,1)
-// TAG-DIRECTIVE("!","!foo")
-// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
-// DOCUMENT-START
-// STREAM-END
-//
-// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
-// line.
-//
-// The document start and end indicators are represented by:
-//
-// DOCUMENT-START
-// DOCUMENT-END
-//
-// Note that if a YAML stream contains an implicit document (without '---'
-// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
-// produced.
-//
-// In the following examples, we present whole documents together with the
-// produced tokens.
-//
-// 1. An implicit document:
-//
-// 'a scalar'
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// SCALAR("a scalar",single-quoted)
-// STREAM-END
-//
-// 2. An explicit document:
-//
-// ---
-// 'a scalar'
-// ...
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// DOCUMENT-START
-// SCALAR("a scalar",single-quoted)
-// DOCUMENT-END
-// STREAM-END
-//
-// 3. Several documents in a stream:
-//
-// 'a scalar'
-// ---
-// 'another scalar'
-// ---
-// 'yet another scalar'
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// SCALAR("a scalar",single-quoted)
-// DOCUMENT-START
-// SCALAR("another scalar",single-quoted)
-// DOCUMENT-START
-// SCALAR("yet another scalar",single-quoted)
-// STREAM-END
-//
-// We have already introduced the SCALAR token above. The following tokens are
-// used to describe aliases, anchors, tag, and scalars:
-//
-// ALIAS(anchor)
-// ANCHOR(anchor)
-// TAG(handle,suffix)
-// SCALAR(value,style)
-//
-// The following series of examples illustrate the usage of these tokens:
-//
-// 1. A recursive sequence:
-//
-// &A [ *A ]
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// ANCHOR("A")
-// FLOW-SEQUENCE-START
-// ALIAS("A")
-// FLOW-SEQUENCE-END
-// STREAM-END
-//
-// 2. A tagged scalar:
-//
-// !!float "3.14" # A good approximation.
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// TAG("!!","float")
-// SCALAR("3.14",double-quoted)
-// STREAM-END
-//
-// 3. Various scalar styles:
-//
-// --- # Implicit empty plain scalars do not produce tokens.
-// --- a plain scalar
-// --- 'a single-quoted scalar'
-// --- "a double-quoted scalar"
-// --- |-
-// a literal scalar
-// --- >-
-// a folded
-// scalar
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// DOCUMENT-START
-// DOCUMENT-START
-// SCALAR("a plain scalar",plain)
-// DOCUMENT-START
-// SCALAR("a single-quoted scalar",single-quoted)
-// DOCUMENT-START
-// SCALAR("a double-quoted scalar",double-quoted)
-// DOCUMENT-START
-// SCALAR("a literal scalar",literal)
-// DOCUMENT-START
-// SCALAR("a folded scalar",folded)
-// STREAM-END
-//
-// Now it's time to review collection-related tokens. We will start with
-// flow collections:
-//
-// FLOW-SEQUENCE-START
-// FLOW-SEQUENCE-END
-// FLOW-MAPPING-START
-// FLOW-MAPPING-END
-// FLOW-ENTRY
-// KEY
-// VALUE
-//
-// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
-// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
-// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the
-// indicators '?' and ':', which are used for denoting mapping keys and values,
-// are represented by the KEY and VALUE tokens.
-//
-// The following examples show flow collections:
-//
-// 1. A flow sequence:
-//
-// [item 1, item 2, item 3]
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// FLOW-SEQUENCE-START
-// SCALAR("item 1",plain)
-// FLOW-ENTRY
-// SCALAR("item 2",plain)
-// FLOW-ENTRY
-// SCALAR("item 3",plain)
-// FLOW-SEQUENCE-END
-// STREAM-END
-//
-// 2. A flow mapping:
-//
-// {
-// a simple key: a value, # Note that the KEY token is produced.
-// ? a complex key: another value,
-// }
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// FLOW-MAPPING-START
-// KEY
-// SCALAR("a simple key",plain)
-// VALUE
-// SCALAR("a value",plain)
-// FLOW-ENTRY
-// KEY
-// SCALAR("a complex key",plain)
-// VALUE
-// SCALAR("another value",plain)
-// FLOW-ENTRY
-// FLOW-MAPPING-END
-// STREAM-END
-//
-// A simple key is a key which is not denoted by the '?' indicator. Note that
-// the Scanner still produce the KEY token whenever it encounters a simple key.
-//
-// For scanning block collections, the following tokens are used (note that we
-// repeat KEY and VALUE here):
-//
-// BLOCK-SEQUENCE-START
-// BLOCK-MAPPING-START
-// BLOCK-END
-// BLOCK-ENTRY
-// KEY
-// VALUE
-//
-// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
-// increase that precedes a block collection (cf. the INDENT token in Python).
-// The token BLOCK-END denote indentation decrease that ends a block collection
-// (cf. the DEDENT token in Python). However YAML has some syntax pecularities
-// that makes detections of these tokens more complex.
-//
-// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
-// '-', '?', and ':' correspondingly.
-//
-// The following examples show how the tokens BLOCK-SEQUENCE-START,
-// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
-//
-// 1. Block sequences:
-//
-// - item 1
-// - item 2
-// -
-// - item 3.1
-// - item 3.2
-// -
-// key 1: value 1
-// key 2: value 2
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// BLOCK-SEQUENCE-START
-// BLOCK-ENTRY
-// SCALAR("item 1",plain)
-// BLOCK-ENTRY
-// SCALAR("item 2",plain)
-// BLOCK-ENTRY
-// BLOCK-SEQUENCE-START
-// BLOCK-ENTRY
-// SCALAR("item 3.1",plain)
-// BLOCK-ENTRY
-// SCALAR("item 3.2",plain)
-// BLOCK-END
-// BLOCK-ENTRY
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("key 1",plain)
-// VALUE
-// SCALAR("value 1",plain)
-// KEY
-// SCALAR("key 2",plain)
-// VALUE
-// SCALAR("value 2",plain)
-// BLOCK-END
-// BLOCK-END
-// STREAM-END
-//
-// 2. Block mappings:
-//
-// a simple key: a value # The KEY token is produced here.
-// ? a complex key
-// : another value
-// a mapping:
-// key 1: value 1
-// key 2: value 2
-// a sequence:
-// - item 1
-// - item 2
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("a simple key",plain)
-// VALUE
-// SCALAR("a value",plain)
-// KEY
-// SCALAR("a complex key",plain)
-// VALUE
-// SCALAR("another value",plain)
-// KEY
-// SCALAR("a mapping",plain)
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("key 1",plain)
-// VALUE
-// SCALAR("value 1",plain)
-// KEY
-// SCALAR("key 2",plain)
-// VALUE
-// SCALAR("value 2",plain)
-// BLOCK-END
-// KEY
-// SCALAR("a sequence",plain)
-// VALUE
-// BLOCK-SEQUENCE-START
-// BLOCK-ENTRY
-// SCALAR("item 1",plain)
-// BLOCK-ENTRY
-// SCALAR("item 2",plain)
-// BLOCK-END
-// BLOCK-END
-// STREAM-END
-//
-// YAML does not always require to start a new block collection from a new
-// line. If the current line contains only '-', '?', and ':' indicators, a new
-// block collection may start at the current line. The following examples
-// illustrate this case:
-//
-// 1. Collections in a sequence:
-//
-// - - item 1
-// - item 2
-// - key 1: value 1
-// key 2: value 2
-// - ? complex key
-// : complex value
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// BLOCK-SEQUENCE-START
-// BLOCK-ENTRY
-// BLOCK-SEQUENCE-START
-// BLOCK-ENTRY
-// SCALAR("item 1",plain)
-// BLOCK-ENTRY
-// SCALAR("item 2",plain)
-// BLOCK-END
-// BLOCK-ENTRY
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("key 1",plain)
-// VALUE
-// SCALAR("value 1",plain)
-// KEY
-// SCALAR("key 2",plain)
-// VALUE
-// SCALAR("value 2",plain)
-// BLOCK-END
-// BLOCK-ENTRY
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("complex key")
-// VALUE
-// SCALAR("complex value")
-// BLOCK-END
-// BLOCK-END
-// STREAM-END
-//
-// 2. Collections in a mapping:
-//
-// ? a sequence
-// : - item 1
-// - item 2
-// ? a mapping
-// : key 1: value 1
-// key 2: value 2
-//
-// Tokens:
-//
-// STREAM-START(utf-8)
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("a sequence",plain)
-// VALUE
-// BLOCK-SEQUENCE-START
-// BLOCK-ENTRY
-// SCALAR("item 1",plain)
-// BLOCK-ENTRY
-// SCALAR("item 2",plain)
-// BLOCK-END
-// KEY
-// SCALAR("a mapping",plain)
-// VALUE
-// BLOCK-MAPPING-START
-// KEY
-// SCALAR("key 1",plain)
-// VALUE
-// SCALAR("value 1",plain)
-// KEY
-// SCALAR("key 2",plain)
-// VALUE
-// SCALAR("value 2",plain)
-// BLOCK-END
-// BLOCK-END
-// STREAM-END
-//
-// YAML also permits non-indented sequences if they are included into a block
-// mapping. In this case, the token BLOCK-SEQUENCE-START is not produced:
-//
-// key:
-// - item 1 # BLOCK-SEQUENCE-START is NOT produced here.
-// - item 2
-//
-// Tokens:

+Important: For safety, please use a protection resistor in this circuit.
Depending on the expected state of the light, the program controls whether or not to provide power in pin-18 of the gpio.
When power is provided in the pin, the LED glows (ON State) and when no power is provided on it then it does not glow (OFF state).
