+## Contributing a change
+
+1. [Fork the repository on GitHub](https://github.com/eclipse/paho.mqtt.javascript/fork)
+2. Clone the forked repository onto your computer: ``` git clone https://github.com/<your username>/paho.mqtt.javascript.git ```
+3. Create a new branch from the latest ```develop``` branch with ```git checkout -b YOUR_BRANCH_NAME origin/develop```
+4. Make your changes
+5. If developing a new feature, make sure to include JUnit tests.
+6. Ensure that all new and existing tests pass.
+7. Commit the changes into the branch: ``` git commit -s ``` Make sure that your commit message is meaningful and describes your changes correctly.
+8. If you have a lot of commits for the change, squash them into a single / few commits.
+9. Push the changes in your branch to your forked repository.
+10. Finally, go to [https://github.com/eclipse/paho.mqtt.javascript](https://github.com/eclipse/paho.mqtt.javascript) and create a pull request from your "YOUR_BRANCH_NAME" branch to the ```develop``` one to request review and merge of the commits in your pushed branch.
+
+
+What happens next depends on the content of the patch. If it is 100% authored
+by the contributor and is less than 1000 lines (and meets the needs of the
+project), then it can be pulled into the main repository. If not, more steps
+are required. These are detailed in the
+[legal process poster](http://www.eclipse.org/legal/EclipseLegalProcessPoster.pdf).

+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.

+
+// Only expose a single object name in the global namespace.
+// Everything must go through this module. Global Paho.MQTT module
+// only has a single public function, client, which returns
+// a Paho.MQTT client object given connection details.
+
+/**
+ * Send and receive messages using web browsers.
+ * <p>
+ * This programming interface lets a JavaScript client application use the MQTT V3.1 or
+ * V3.1.1 protocol to connect to an MQTT-supporting messaging server.
+ *
+ * The function supported includes:
+ * <ol>
+ * <li>Connecting to and disconnecting from a server. The server is identified by its host name and port number.
+ * <li>Specifying options that relate to the communications link with the server,
+ * for example the frequency of keep-alive heartbeats, and whether SSL/TLS is required.
+ * <li>Subscribing to and receiving messages from MQTT Topics.
+ * <li>Publishing messages to MQTT Topics.
+ * </ol>
+ * <p>
+ * The API consists of two main objects:
+ * <dl>
+ * <dt><b>{@link Paho.MQTT.Client}</b></dt>
+ * <dd>This contains methods that provide the functionality of the API,
+ * including provision of callbacks that notify the application when a message
+ * arrives from or is delivered to the messaging server,
+ * or when the status of its connection to the messaging server changes.</dd>
+ * <dt><b>{@link Paho.MQTT.Message}</b></dt>
+ * <dd>This encapsulates the payload of the message along with various attributes
+ * associated with its delivery, in particular the destination to which it has
+ * been (or is about to be) sent.</dd>
+ * </dl>
+ * <p>
+ * The programming interface validates parameters passed to it, and will throw
+ * an Error containing an error message intended for developer use, if it detects
+ * an error with any parameter.
+ * <p>
+ * Example:
+ *
+ * <code><pre>
+client = new Paho.MQTT.Client(location.hostname, Number(location.port), "clientId");
+client.onConnectionLost = onConnectionLost;
+client.onMessageArrived = onMessageArrived;
+client.connect({onSuccess:onConnect});
+
+function onConnect() {
+ // Once a connection has been made, make a subscription and send a message.
+ console.log("onConnect");
+ client.subscribe("/World");
+ message = new Paho.MQTT.Message("Hello");
+ message.destinationName = "/World";
+ client.send(message);
+};
+function onConnectionLost(responseObject) {
+ if (responseObject.errorCode !== 0)
+ console.log("onConnectionLost:"+responseObject.errorMessage);
+};
+function onMessageArrived(message) {
+ console.log("onMessageArrived:"+message.payloadString);
+ client.disconnect();
+};

+ * The JavaScript application communicates to the server using a {@link Paho.MQTT.Client} object.
+ * <p>
+ * Most applications will create just one Client object and then call its connect() method,
+ * however applications can create more than one Client object if they wish.
+ * In this case the combination of host, port and clientId attributes must be different for each Client object.
+ * <p>
+ * The send, subscribe and unsubscribe methods are implemented as asynchronous JavaScript methods
+ * (even though the underlying protocol exchange might be synchronous in nature).
+ * This means they signal their completion by calling back to the application,
+ * via Success or Failure callback functions provided by the application on the method in question.
+ * Such callbacks are called at most once per method invocation and do not persist beyond the lifetime
+ * of the script that made the invocation.
+ * <p>
+ * In contrast there are some callback functions, most notably <i>onMessageArrived</i>,
+ * that are defined on the {@link Paho.MQTT.Client} object.
+ * These may get called multiple times, and aren't directly related to specific method invocations made by the client.
+ *
+ * @name Paho.MQTT.Client
+ *
+ * @constructor
+ *
+ * @param {string} host - the address of the messaging server, as a fully qualified WebSocket URI, as a DNS name or dotted decimal IP address.
+ * @param {number} port - the port number to connect to - only required if host is not a URI
+ * @param {string} path - the path on the host to connect to - only used if host is not a URI. Default: '/mqtt'.
+ * @param {string} clientId - the Messaging client identifier, between 1 and 23 characters in length.
+ *
+ * @property {string} host - <i>read only</i> the server's DNS hostname or dotted decimal IP address.
+ * @property {number} port - <i>read only</i> the server's port.
+ * @property {string} path - <i>read only</i> the server's path.
+ * @property {string} clientId - <i>read only</i> used when connecting to the server.
+ * @property {function} onConnectionLost - called when a connection has been lost.
+ * after a connect() method has succeeded.
+ * Establish the call back used when a connection has been lost. The connection may be
+ * lost because the client initiates a disconnect or because the server or network
+ * cause the client to be disconnected. The disconnect call back may be called without
+ * the connectionComplete call back being invoked if, for example the client fails to
+ * connect.
+ * A single response object parameter is passed to the onConnectionLost callback containing the following fields:
+ * <ol>
+ * <li>errorCode
+ * <li>errorMessage
+ * </ol>
+ * @property {function} onMessageDelivered - called when a message has been delivered.
+ * All processing that this Client will ever do has been completed. So, for example,
+ * in the case of a Qos=2 message sent by this client, the PubComp flow has been received from the server
+ * and the message has been removed from persistent storage before this callback is invoked.
+ * Parameters passed to the onMessageDelivered callback are:
+ * <ol>
+ * <li>{@link Paho.MQTT.Message} that was delivered.
+ * </ol>
+ * @property {function} onMessageArrived - called when a message has arrived in this Paho.MQTT.client.
+ * Parameters passed to the onMessageArrived callback are:
+ * <ol>
+ * <li>{@link Paho.MQTT.Message} that has arrived.
+ * </ol>
+ * @property {function} onConnected - called when a connection is successfully made to the server.
+ * after a connect() method.
+ * Parameters passed to the onConnected callback are:
+ * <ol>
+ * <li>reconnect (boolean) - If true, the connection was the result of a reconnect.</li>
+ * <li>URI (string) - The URI used to connect to the server.</li>
+ * </ol>
+ * @property {boolean} disconnectedPublishing - if set, will enable disconnected publishing in
+ * in the event that the connection to the server is lost.
+ * @property {number} disconnectedBufferSize - Used to set the maximum number of messages that the disconnected
+ * buffer will hold before rejecting new messages. Default size: 5000 messages
+ * @property {function} trace - called whenever trace is called. TODO
