noVNC 1.3.0

The way we work with these translation files means that we only care
about one step at a time, we don't want to update the .po files when
building the 'update-js' target.

Also, always force rebuilds of the .po and .json files.

-How to contribute to noVNC
-==========================
-
-We accept code via pull requests on GitHub.  There are several guidelines that
-we expect contributors submitting code requests to follow.  If you have issues
-following any of these guidelines, feel free to drop us a line by leaving a
-comment in the code request or sending us an email.
-
-Contributing Guidelines
------------------------
-
-* While we don't have an official coding style guide, please try to follow
-  the general coding style of the existing code.
-** Use four spaces instead of tabs 
-** prefix private variables and functions with an `_`
-
-* Please try to include unit tests for your code.  For instance, if you
-  introduce a new encoding, add a test to `tests/test.rfb.js` under the
-  "Encoding Handlers" section (basically, input a small pattern in your
-  encoding and make sure the pattern gets displayed correctly).  If you
-  fix a bug, try to add a unit test that would have caught that bug
-  (if possible -- some bugs, especially visual ones, are hard to test for).
-
-* Squash your commits down in to a clean commit history.  For instance, there
-  should not be "cleanup" commits where you fix issues in previous commits in
-  the same pull request.  Before you go to commit, use `git rebase -i` to
-  squash these changes into the relevant commits.  For instance, a good commit
-  history might look like "Added support for FOO encoding, Added support for
-  BAR message, Placed Button in UI to Trigger BAR" (where each comma denotes
-  a separate commit).
-
-* Add both a title and description to your commit, if possible.  Place more
-  detail on what you did in the description.
-
-Running the unit tests
-----------------------
-
-There are two ways to run the unit tests.  For both ways, you should first run
-`npm install` (not as root).
-
-The first way to run the tests is to run `npm test`.  This will run all the
-tests in the headless PhantomJS browser (which uses WebKit).
-
-The second way to run the tests is using the `tests/run_from_console.js` file.
-This way is a bit more flexible, and can provide more information about what
-went wrong.  To run all the tests, simply run `tests/run_from_console.js`.
-To run a specific test file, you can use the `-t path/to/test/file.js` option.
-If you wish to simply generate the HTML for the test, use the `-g` option, and
-the path to the temporary HTML file will be written to standard out.  To open
-this file in your default browser automatically, pass the `-o` option as well.
-More information can be found by passing the `--help` or `-h` option.
-
-
-Thanks, and happy coding!

 ### Browser Requirements
 
-* Chrome 8, Firefox 4, Safari 6, Opera 12, IE 11, Edge 12, etc.
+noVNC uses many modern web technologies so a formal requirement list is
+not available. However these are the minimum versions we are currently
+aware of:
 
-* HTML5 Canvas, WebSockets and Typed Arrays
-
-* Fast Javascript Engine: this is not strictly a requirement, but without a
-  fast Javascript engine, noVNC might be painfully slow.
-
-* See the more detailed
-[browser compatibility wiki page](https://github.com/novnc/noVNC/wiki/Browser-support).
+* Chrome 64, Firefox 79, Safari 13.4, Opera 51, Edge 79
 
 
 ### Server Requirements
 
-Unless you are using a VNC server with support for WebSockets connections (such
-as [x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
-[QEMU](http://www.qemu.org/), or
-[MobileVNC](http://www.smartlab.at/mobilevnc/)), you need to use a
-WebSockets to TCP socket proxy. There is a python proxy included
-('websockify').
+noVNC follows the standard VNC protocol, but unlike other VNC clients it does
+require WebSockets support. Many servers include support (e.g.
+[x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
+[QEMU](http://www.qemu.org/), and
+[MobileVNC](http://www.smartlab.at/mobilevnc/)), but for the others you need to
+use a WebSockets to TCP socket proxy. noVNC has a sister project
+[websockify](https://github.com/novnc/websockify) that provides a simple such
+proxy.
 
 
 ### Quick Start
 
-* Use the launch script to start a mini-webserver and the WebSockets proxy
-  (websockify). The `--vnc` option is used to specify the location of a running
-  VNC server:
+* Use the `novnc_proxy` script to automatically download and start websockify, which
+  includes a mini-webserver and the WebSockets proxy. The `--vnc` option is
+  used to specify the location of a running VNC server:
 
-    `./utils/launch.sh --vnc localhost:5901`
+    `./utils/novnc_proxy --vnc localhost:5901`
 
-* Point your browser to the cut-and-paste URL that is output by the launch
-  script. Enter a password if the VNC server has one configured. Hit the
-  Connect button and enjoy!
+* Point your browser to the cut-and-paste URL that is output by the `novnc_procy`
+  script. Hit the Connect button, enter a password if the VNC server has one
+  configured, and enjoy!
 
+### Installation from Snap Package
+Running the command below will install the latest release of noVNC from Snap:
 
-### Other Pages
+`sudo snap install novnc`
 
-* [Modules/API](https://github.com/novnc/noVNC/wiki/Modules-API) - The library
-  modules and their Javascript API.
+#### Running noVNC
 
-* [Integration](https://github.com/novnc/noVNC/wiki/Integration) - Get noVNC
-  to work in existing projects.
+You can run the Snap-package installed novnc directly with, for example:
 
-* [Troubleshooting](https://github.com/novnc/noVNC/wiki/Troubleshooting) - How
-  to troubleshoot problems.
+`novnc --listen 6081 --vnc localhost:5901 # /snap/bin/novnc if /snap/bin is not in your PATH`
 
-* [Encrypted Connections](https://github.com/novnc/websockify/wiki/Encrypted-Connections) -
-  Setup websockify so that you can use encrypted connections from noVNC.
+#### Running as a Service (Daemon)
+The Snap package also has the capability to run a 'novnc' service which can be 
+configured to listen on multiple ports connecting to multiple VNC servers 
+(effectively a service runing multiple instances of novnc).
+Instructions (with example values):
 
-* [Advanced Usage](https://github.com/novnc/noVNC/wiki/Advanced-usage) -
-  Generating an SSL certificate, starting a VNC server, advanced websockify
-  usage, etc.
+List current services (out-of-box this will be blank):
 
-* [Testing](https://github.com/novnc/noVNC/wiki/Testing) - Run and write
-  tests.
+```
+sudo snap get novnc services
+Key             Value
+services.n6080  {...}
+services.n6081  {...}
+```
 
-* [Translations](https://github.com/novnc/noVNC/wiki/Translations) - Add and
-  modify localization for JavaScript and HTML.
+Create a new service that listens on port 6082 and connects to the VNC server 
+running on port 5902 on localhost:
+
+`sudo snap set novnc services.n6082.listen=6082 services.n6082.vnc=localhost:5902`
+
+(Any services you define with 'snap set' will be automatically started)
+Note that the name of the service, 'n6082' in this example, can be anything 
+as long as it doesn't start with a number or contain spaces/special characters.
+
+View the configuration of the service just created:
+
+```
+sudo snap get novnc services.n6082
+Key                    Value
+services.n6082.listen  6082
+services.n6082.vnc     localhost:5902
+```
+
+Disable a service (note that because of a limitation in  Snap it's currently not 
+possible to unset config variables, setting them to blank values is the way 
+to disable a service):
+
+`sudo snap set novnc services.n6082.listen='' services.n6082.vnc=''`
+
+(Any services you set to blank with 'snap set' like this will be automatically stopped)
+
+Verify that the service is disabled (blank values):
+
+```
+sudo snap get novnc services.n6082
+Key                    Value
+services.n6082.listen  
+services.n6082.vnc
+```
+
+### Integration and Deployment
+
+Please see our other documents for how to integrate noVNC in your own software,
+or deploying the noVNC application in production environments:
+
+* [Embedding](docs/EMBEDDING.md) - For the noVNC application
+* [Library](docs/LIBRARY.md) - For the noVNC JavaScript library

+# 1. Internal Modules
+
+The noVNC client is composed of several internal modules that handle
+rendering, input, networking, etc. Each of the modules is designed to
+be cross-browser and independent from each other.
+
+Note however that the API of these modules is not guaranteed to be
+stable, and this documentation is not maintained as well as the
+official external API.
+
+
+## 1.1 Module List
+
+* __Keyboard__ (core/input/keyboard.js): Keyboard input event handler with
+non-US keyboard support. Translates keyDown and keyUp events to X11
+keysym values.
+
+* __Display__ (core/display.js): Efficient 2D rendering abstraction
+layered on the HTML5 canvas element.
+
+* __Websock__ (core/websock.js): Websock client from websockify
+with transparent binary data support.
+[Websock API](https://github.com/novnc/websockify-js/wiki/websock.js) wiki page.
+
+
+## 1.2 Callbacks
+
+For the Mouse, Keyboard and Display objects the callback functions are
+assigned to configuration attributes, just as for the RFB object. The
+WebSock module has a method named 'on' that takes two parameters: the
+callback event name, and the callback function.

+# noVNC API
+
+The interface of the noVNC client consists of a single RFB object that
+is instantiated once per connection.
+
+## RFB
+
+The `RFB` object represents a single connection to a VNC server. It
+communicates using a WebSocket that must provide a standard RFB
+protocol stream.
+
+### Constructor
+
+[`RFB()`](#rfb-1)
+  - Creates and returns a new `RFB` object.
+
+### Properties
+
+`viewOnly`
+  - Is a `boolean` indicating if any events (e.g. key presses or mouse
+    movement) should be prevented from being sent to the server.
+    Disabled by default.
+
+`focusOnClick`
+  - Is a `boolean` indicating if keyboard focus should automatically be
+    moved to the remote session when a `mousedown` or `touchstart`
+    event is received. Enabled by default.
+
+`clipViewport`
+  - Is a `boolean` indicating if the remote session should be clipped
+    to its container. When disabled scrollbars will be shown to handle
+    the resulting overflow. Disabled by default.
+
+`dragViewport`
+  - Is a `boolean` indicating if mouse events should control the
+    relative position of a clipped remote session. Only relevant if
+    `clipViewport` is enabled. Disabled by default.
+
+`scaleViewport`
+  - Is a `boolean` indicating if the remote session should be scaled
+    locally so it fits its container. When disabled it will be centered
+    if the remote session is smaller than its container, or handled
+    according to `clipViewport` if it is larger. Disabled by default.
+
+`resizeSession`
+  - Is a `boolean` indicating if a request to resize the remote session
+    should be sent whenever the container changes dimensions. Disabled
+    by default.
+
+`showDotCursor`
+  - Is a `boolean` indicating whether a dot cursor should be shown
+    instead of a zero-sized or fully-transparent cursor if the server
+    sets such invisible cursor. Disabled by default.
+
+`background`
+  - Is a valid CSS [background](https://developer.mozilla.org/en-US/docs/Web/CSS/background)
+    style value indicating which background style should be applied
+    to the element containing the remote session screen. The default value is `rgb(40, 40, 40)`
+    (solid gray color).
+
+`qualityLevel`
+  - Is an `int` in range `[0-9]` controlling the desired JPEG quality.
+    Value `0` implies low quality and `9` implies high quality.
+    Default value is `6`.
+
+`compressionLevel`
+  - Is an `int` in range `[0-9]` controlling the desired compression
+    level. Value `0` means no compression. Level 1 uses a minimum of CPU
+    resources and achieves weak compression ratios, while level 9 offers
+    best compression but is slow in terms of CPU consumption on the server
+    side. Use high levels with very slow network connections.
+    Default value is `2`.
+
+`capabilities` *Read only*
+  - Is an `Object` indicating which optional extensions are available
+    on the server. Some methods may only be called if the corresponding
+    capability is set. The following capabilities are defined:
+
+    | name     | type      | description
+    | -------- | --------- | -----------
+    | `power`  | `boolean` | Machine power control is available
+
+### Events
+
+[`connect`](#connect)
+  - The `connect` event is fired when the `RFB` object has completed
+    the connection and handshaking with the server.
+
+[`disconnect`](#disconnected)
+  - The `disconnect` event is fired when the `RFB` object disconnects.
+
+[`credentialsrequired`](#credentialsrequired)
+  - The `credentialsrequired` event is fired when more credentials must
+    be given to continue.
+
+[`securityfailure`](#securityfailure)
+  - The `securityfailure` event is fired when the security negotiation
+    with the server fails.
+
+[`clipboard`](#clipboard)
+  - The `clipboard` event is fired when clipboard data is received from
+    the server.
+
+[`bell`](#bell)
+  - The `bell` event is fired when a audible bell request is received
+    from the server.
+
+[`desktopname`](#desktopname)
+  - The `desktopname` event is fired when the remote desktop name
+    changes.
+
+[`capabilities`](#capabilities)
+  - The `capabilities` event is fired when `RFB.capabilities` is
+    updated.
+
+### Methods
+
+[`RFB.disconnect()`](#rfbdisconnect)
+  - Disconnect from the server.
+
+[`RFB.sendCredentials()`](#rfbsendcredentials)
+  - Send credentials to server. Should be called after the
+    [`credentialsrequired`](#credentialsrequired) event has fired.
+
+[`RFB.sendKey()`](#rfbsendKey)
+  - Send a key event.
+
+[`RFB.sendCtrlAltDel()`](#rfbsendctrlaltdel)
+  - Send Ctrl-Alt-Del key sequence.
+
+[`RFB.focus()`](#rfbfocus)
+  - Move keyboard focus to the remote session.
+
+[`RFB.blur()`](#rfbblur)
+  - Remove keyboard focus from the remote session.
+
+[`RFB.machineShutdown()`](#rfbmachineshutdown)
+  - Request a shutdown of the remote machine.
+
+[`RFB.machineReboot()`](#rfbmachinereboot)
+  - Request a reboot of the remote machine.

+[`RFB.machineReset()`](#rfbmachinereset)
+  - Request a reset of the remote machine.
+
+[`RFB.clipboardPasteFrom()`](#rfbclipboardPasteFrom)
+  - Send clipboard contents to server.
+
+### Details
+
+#### RFB()
+
+The `RFB()` constructor returns a new `RFB` object and initiates a new
+connection to a specified VNC server.
+
+##### Syntax
+
+    let rfb = new RFB( target, url [, options] );
+
+###### Parameters
+
+**`target`**
+  - A block [`HTMLElement`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement)
+    that specifies where the `RFB` object should attach itself. The
+    existing contents of the `HTMLElement` will be untouched, but new
+    elements will be added during the lifetime of the `RFB` object.
+
+**`urlOrDataChannel`**
+  - A `DOMString` specifying the VNC server to connect to. This must be
+    a valid WebSocket URL. This can also be a `WebSocket` or `RTCDataChannel`.
+
+**`options`** *Optional*
+  - An `Object` specifying extra details about how the connection
+    should be made.
+
+    Possible options:
+
+    `shared`
+      - A `boolean` indicating if the remote server should be shared or
+        if any other connected clients should be disconnected. Enabled
+        by default.
+
+    `credentials`
+      - An `Object` specifying the credentials to provide to the server
+        when authenticating. The following credentials are possible:
+
+        | name         | type        | description
+        | ------------ | ----------- | -----------
+        | `"username"` | `DOMString` | The user that authenticates
+        | `"password"` | `DOMString` | Password for the user
+        | `"target"`   | `DOMString` | Target machine or session
+
+    `repeaterID`
+      - A `DOMString` specifying the ID to provide to any VNC repeater
+        encountered.
+
+    `wsProtocols`
+      - An `Array` of `DOMString`s specifying the sub-protocols to use
+        in the WebSocket connection. Empty by default.
+
+#### connect
+
+The `connect` event is fired after all the handshaking with the server
+is completed and the connection is fully established. After this event
+the `RFB` object is ready to recieve graphics updates and to send input.
+
+#### disconnect
+
+The `disconnect` event is fired when the connection has been
+terminated. The `detail` property is an `Object` that contains the
+property `clean`. `clean` is a `boolean` indicating if the termination
+was clean or not. In the event of an unexpected termination or an error
+`clean` will be set to false.
+
+#### credentialsrequired
+
+The `credentialsrequired` event is fired when the server requests more
+credentials than were specified to [`RFB()`](#rfb-1). The `detail`
+property is an `Object` containing the property `types` which is an
+`Array` of `DOMString` listing the credentials that are required.
+
+#### securityfailure
+
+The `securityfailure` event is fired when the handshaking process with
+the server fails during the security negotiation step. The `detail`
+property is an `Object` containing the following properties:
+
+| Property | Type        | Description
+| -------- | ----------- | -----------
+| `status` | `long`      | The failure status code
+| `reason` | `DOMString` | The **optional** reason for the failure
+
+The property `status` corresponds to the
+[SecurityResult](https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#securityresult)
+status code in cases of failure. A status of zero will not be sent in
+this event since that indicates a successful security handshaking
+process. The optional property `reason` is provided by the server and
+thus the language of the string is not known. However most servers will
+probably send English strings. The server can choose to not send a
+reason and in these cases the `reason` property will be omitted.
+
+#### clipboard
+
+The `clipboard` event is fired when the server has sent clipboard data.
+The `detail` property is an `Object` containing the property `text`
+which is a `DOMString` with the clipboard data.
+
+#### bell
+
+The `bell` event is fired when the server has requested an audible
+bell.
+
+#### desktopname
+
+The `desktopname` event is fired when the name of the remote desktop
+changes. The `detail` property is an `Object` with the property `name`
+which is a `DOMString` specifying the new name.
+
+#### capabilities
+
+The `capabilities` event is fired whenever an entry is added or removed
+from `RFB.capabilities`. The `detail` property is an `Object` with the
+property `capabilities` containing the new value of `RFB.capabilities`.
+
+#### RFB.disconnect()
+
+The `RFB.disconnect()` method is used to disconnect from the currently
+connected server.
+
+##### Syntax
+
+    RFB.disconnect( );
+
+#### RFB.sendCredentials()

+###### Parameters
+
+**`credentials`**
+  - An `Object` specifying the credentials to provide to the server
+    when authenticating. See [`RFB()`](#rfb-1) for details.
+
+#### RFB.sendKey()
+
+The `RFB.sendKey()` method is used to send a key event to the server.
+
+##### Syntax
+
+    RFB.sendKey( keysym, code [, down] );

+    If the physical key cannot be determined then `null` shall be
+    specified.
+
+**`down`** *Optional*
+  - A `boolean` specifying if a press or a release event should be
+    sent. If omitted then both a press and release event are sent.
+
+#### RFB.sendCtrlAltDel()
+
+The `RFB.sendCtrlAltDel()` method is used to send the key sequence
+*left Control*, *left Alt*, *Delete*. This is a convenience wrapper
+around [`RFB.sendKey()`](#rfbsendkey).
+
+##### Syntax
+
+    RFB.sendCtrlAltDel( );
+
+#### RFB.focus()
+
+The `RFB.focus()` method sets the keyboard focus on the remote session.

+# Embedding and Deploying noVNC Application
+
+This document describes how to embed and deploy the noVNC application, which
+includes settings and a full user interface. If you are looking for
+documentation on how to use the core noVNC library in your own application,
+then please see our [library documentation](LIBRARY.md).
+
+## Files
+
+The noVNC application consists of the following files and directories:
+
+* `vnc.html` - The main page for the application and where users should go. It
+  is possible to rename this file.
+
+* `app/` - Support files for the application. Contains code, images, styles and
+  translations.
+
+* `core/` - The core noVNC library.
+
+* `vendor/` - Third party support libraries used by the application and the
+  core library.
+
+The most basic deployment consists of simply serving these files from a web
+server and setting up a WebSocket proxy to the VNC server.
+
+## Parameters
+
+The noVNC application can be controlled by including certain settings in the
+query string. Currently the following options are available:
+
+* `autoconnect` - Automatically connect as soon as the page has finished
+  loading.
+
+* `reconnect` - If noVNC should automatically reconnect if the connection is
+  dropped.
+
+* `reconnect_delay` - How long to wait in milliseconds before attempting to
+  reconnect.
+
+* `host` - The WebSocket host to connect to.
+
+* `port` - The WebSocket port to connect to.
+
+* `encrypt` - If TLS should be used for the WebSocket connection.
+
+* `path` - The WebSocket path to use.
+
+* `password` - The password sent to the server, if required.
+
+* `repeaterID` - The repeater ID to use if a VNC repeater is detected.
+
+* `shared` - If other VNC clients should be disconnected when noVNC connects.
+
+* `bell` - If the keyboard bell should be enabled or not.
+
+* `view_only` - If the remote session should be in non-interactive mode.
+
+* `view_clip` - If the remote session should be clipped or use scrollbars if
+  it cannot fit in the browser.
+
+* `resize` - How to resize the remote session if it is not the same size as
+  the browser window. Can be one of `off`, `scale` and `remote`.
+
+* `quality` - The session JPEG quality level. Can be `0` to `9`.
+
+* `compression` - The session compression level. Can be `0` to `9`.
+
+* `show_dot` - If a dot cursor should be shown when the remote server provides
+  no local cursor, or provides a fully-transparent (invisible) cursor.
+
+* `logging` - The console log level. Can be one of `error`, `warn`, `info` or
+  `debug`.
+
+## HTTP Serving Considerations
+### Browser Cache Issue
+
+If you serve noVNC files using a web server that provides an ETag header, and
+include any options in the query string, a nasty browser cache issue can bite
+you on upgrade, resulting in a red error box. The issue is caused by a mismatch
+between the new vnc.html (which is reloaded because the user has used it with
+new query string after the upgrade) and the old javascript files (that the
+browser reuses from its cache). To avoid this issue, the browser must be told
+to always revalidate cached files using conditional requests. The correct
+semantics are achieved via the (confusingly named) `Cache-Control: no-cache`
+header that needs to be provided in the web server responses.
+
+### Example Server Configurations
+
+Apache:
+
+```
+    # In the main configuration file
+    # (Debian/Ubuntu users: use "a2enmod headers" instead)
+    LoadModule headers_module modules/mod_headers.so
+
+    # In the <Directory> or <Location> block related to noVNC
+    Header set Cache-Control "no-cache"
+```
+
+Nginx:
+
+```
+    # In the location block related to noVNC
+    add_header Cache-Control no-cache;
+```

+# Using the noVNC JavaScript library
+
+This document describes how to make use of the noVNC JavaScript library for
+integration in your own VNC client application. If you wish to embed the more
+complete noVNC application with its included user interface then please see
+our [embedding documentation](EMBEDDING.md).
+
+## API
+
+The API of noVNC consists of a single object called `RFB`. The formal
+documentation for that object can be found in our [API documentation](API.md).
+
+## Example
+
+noVNC includes a small example application called `vnc_lite.html`. This does
+not make use of all the features of noVNC, but is a good start to see how to
+do things.
+
+## Conversion of Modules
+
+noVNC is written using ECMAScript 6 modules. This is not supported by older
+versions of Node.js. To use noVNC with those older versions of Node.js the
+library must first be converted.
+
+Fortunately noVNC includes a script to handle this conversion. Please follow
+the following steps:
+
+ 1. Install Node.js
+ 2. Run `npm install` in the noVNC directory
+
+The result of the conversion is available in the `lib/` directory.

-          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.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS

-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.
