+                       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.

+Community
+---------
+
+Please join the [mailing list](https://groups.google.com/forum/#!forum/go-qml) for
+following relevant development news and discussing project details.
+
+
+Installation
+------------
+
+To try the alpha release you'll need:
+
+  * Go >= 1.2, for the C++ support of _go build_
+  * Qt 5.0.X or 5.1.X with the development files
+  * The Qt headers qmetaobject_p.h and qmetaobjectbuilder_p.h, for the dynamic meta object support
+
+See below for more details about getting these requirements installed in different environments and operating systems.
+
+After the requirements are satisfied, _go get_ should work as usual:
+
+    go get gopkg.in/qml.v1
+
+
+Requirements on Ubuntu
+----------------------
+
+If you are using Ubuntu, the [Ubuntu SDK](http://developer.ubuntu.com/get-started/) will take care of the Qt dependencies:
+
+    $ sudo add-apt-repository ppa:ubuntu-sdk-team/ppa
+    $ sudo apt-get update
+    $ sudo apt-get install qtdeclarative5-dev qtbase5-private-dev qtdeclarative5-private-dev libqt5opengl5-dev qtdeclarative5-qtquick2-plugin
+
+and Go >= 1.2 may be installed using [godeb](http://blog.labix.org/2013/06/15/in-flight-deb-packages-of-go):
+
+    $ # Pick the right one for your system: 386 or amd64
+    $ ARCH=amd64
+    $ wget -q https://godeb.s3.amazonaws.com/godeb-$ARCH.tar.gz
+    $ tar xzvf godeb-$ARCH.tar.gz
+    godeb
+    $ sudo mv godeb /usr/local/bin
+    $ godeb install
+    $ go get gopkg.in/qml.v1
+
+
+Requirements on Ubuntu Touch
+----------------------------
+
+After following the [installation instructions](https://wiki.ubuntu.com/Touch/Install) for Ubuntu Touch,
+run the following commands to get a working build environment inside the device:
+
+    $ adb shell
+    # cd /tmp
+    # wget https://github.com/go-qml/qml/raw/v1/cmd/ubuntu-touch/setup.sh
+    # /bin/bash setup.sh
+    # su - phablet
+    $
+
+At the end of setup.sh, the phablet user will have GOPATH=$HOME in the environment,
+the qml package will be built, and the particle example will be built and run. For
+stopping it from the command line, run as the phablet user:
+
+    $ ubuntu-app-stop gopkg.in.qml.particle-example
+
+for running it again:
+
+    $ ubuntu-app-launch gopkg.in.qml.particle-example
+
+These commands depend on the following file, installed by setup.sh:
+
+    ~/.local/share/applications/gopkg.in.qml.particle-example.desktop
+
+
+Requirements on Mac OS X
+------------------------
+
+On Mac OS X you'll need QT5. It's easiest to install with Homebrew, a
+third-party package management system for OS X.
+
+Installation instructions for Homebrew are here:
+
+    http://brew.sh/
+
+Then, install the qt5 and pkg-config packages:
+
+    $ brew install qt5 pkg-config
+
+Then, force brew to "link" qt5 (this makes it available under /usr/local):
+
+    $ brew link --force qt5
+
+And finally, fetch and install go-qml:
+
+    $ go get gopkg.in/qml.v1
+
+
+Requirements on Windows
+-----------------------
+
+On Windows you'll need the following:
+
+  * [MinGW gcc](http://sourceforge.net/projects/mingw/files/latest/download) 4.8.1 (install mingw-get and install the gcc from within the setup GUI)
+  * [Qt 5.1.1](http://download.qt-project.org/official_releases/qt/5.1/5.1.1/qt-windows-opensource-5.1.1-mingw48_opengl-x86-offline.exe) for MinGW 4.8
+  * [Go >= 1.2](http://golang.org/doc/install)
+
+Then, assuming Qt was installed under `C:\Qt5.1.1\`, set up the following environment variables in the respective configuration:
+
+    CPATH += C:\Qt5.1.1\5.1.1\mingw48_32\include
+    LIBRARY_PATH += C:\Qt5.1.1\5.1.1\mingw48_32\lib
+    PATH += C:\Qt5.1.1\5.1.1\mingw48_32\bin
+
+After reopening the shell for the environment changes to take effect, this should work:
+
+    go get gopkg.in/qml.v1
+
+
+Requirements everywhere else
+----------------------------
+
+If your operating system does not offer these dependencies readily,
+you may still have success installing [Go >= 1.2](http://golang.org/doc/install)
+and [Qt 5.0.2](http://download.qt-project.org/archive/qt/5.0/5.0.2/)
+directly from the upstreams.  Note that you'll likely have to adapt
+environment variables to reflect the custom installation path for
+these libraries. See the instructions above for examples.

+// Package qml offers graphical QML application support for the Go language.
+//
+// Attention
+//
+// This package is in an alpha stage, and still in heavy development. APIs may
+// change, and things may break.
+//
+// At this time contributors and developers that are interested in tracking the
+// development closely are encouraged to use it. If you'd prefer a more stable
+// release, please hold on a bit and subscribe to the mailing list for news. It's
+// in a pretty good state, so it shall not take too long.
+//
+// See http://github.com/go-qml/qml for details.
+//
+//
+// Introduction
+//
+// The qml package enables Go programs to display and manipulate graphical content
+// using Qt's QML framework. QML uses a declarative language to express structure
+// and style, and supports JavaScript for in-place manipulation of the described
+// content. When using the Go qml package, such QML content can also interact with
+// Go values, making use of its exported fields and methods, and even explicitly
+// creating new instances of registered Go types.
+//
+// A simple Go application that integrates with QML may perform the following steps
+// for offering a graphical interface:
+//
+//   * Call qml.Run from function main providing a function with the logic below
+//   * Create an engine for loading and running QML content (see NewEngine)
+//   * Make Go values and types available to QML (see Context.SetVar and RegisterType)
+//   * Load QML content (see Engine.LoadString and Engine.LoadFile)
+//   * Create a new window for the content (see Component.CreateWindow)
+//   * Show the window and wait for it to be closed (see Window.Show and Window.Wait)
+//
+// Some of these topics are covered below, and may also be observed in practice
+// in the following examples:
+//
+//   https://github.com/go-qml/qml/tree/v1/examples
+//
+//
+// Simple example
+//
+// The following logic demonstrates loading a QML file into a window:
+//
+//    func main() {
+//            err := qml.Run(run)
+//            ...
+//    }
+//
+//    func run() error {
+//            engine := qml.NewEngine()
+//            component, err := engine.LoadFile("file.qml")
+//            if err != nil {
+//                    return err
+//            }
+//            win := component.CreateWindow(nil)
+//            win.Show()
+//            win.Wait()
+//            return nil
+//    }
+//
+// Handling QML objects in Go
+//
+// Any QML object may be manipulated by Go via the Object interface. That
+// interface is implemented both by dynamic QML values obtained from a running
+// engine, and by Go types in the qml package that represent QML values, such as
+// Window, Context, and Engine.
+//
+// For example, the following logic creates a window and prints its width
+// whenever it's made visible:
+//
+//    win := component.CreateWindow(nil)
+//    win.On("visibleChanged", func(visible bool) {
+//            if (visible) {
+//                    fmt.Println("Width:", win.Int("width"))
+//            }
+//    })
+//
+// Information about the methods, properties, and signals that are available for QML
+// objects may be obtained in the Qt documentation. As a reference, the "visibleChanged"
+// signal and the "width" property used in the example above are described at:
+//
+//    http://qt-project.org/doc/qt-5.0/qtgui/qwindow.html
+//
+// When in doubt about what type is being manipulated, the Object.TypeName method
+// provides the type name of the underlying value.
+//
+//
+// Publishing Go values to QML
+//
+// The simplest way of making a Go value available to QML code is setting it
+// as a variable of the engine's root context, as in:
+//
+//    context := engine.Context()
+//    context.SetVar("person", &Person{Name: "Ale"})
+//
+// This logic would enable the following QML code to successfully run:
+//
+//    import QtQuick 2.0
+//    Item {
+//        Component.onCompleted: console.log("Name is", person.name)
+//    }
+//
+//
+// Publishing Go types to QML
+//
+// While registering an individual Go value as described above is a quick way to get
+// started, it is also fairly limited. For more flexibility, a Go type may be
+// registered so that QML code can natively create new instances in an arbitrary
+// position of the structure. This may be achieved via the RegisterType function, as
+// the following example demonstrates:
+//
+//    qml.RegisterTypes("GoExtensions", 1, 0, []qml.TypeSpec{{
+//            Init: func(p *Person, obj qml.Object) { p.Name = "<none>" },
+//    }})
+//
+// With this logic in place, QML code can create new instances of Person by itself:     
+//
+//    import QtQuick 2.0
+//    import GoExtensions 1.0
+//    Item{
+//        Person {
+//            id: person
+//            name: "Ale"
+//        }
+//        Component.onCompleted: console.log("Name is", person.name)
+//    }
+//
+//
+// Lowercasing of names
+// 
+// Independently from the mechanism used to publish a Go value to QML code, its methods
+// and fields are available to QML logic as methods and properties of the
+// respective QML object representing it. As required by QML, though, the Go
+// method and field names are lowercased according to the following scheme when
+// being accesed from QML:
+//
+//    value.Name      => value.name
+//    value.UPPERName => value.upperName
+//    value.UPPER     => value.upper
+//
+//
+// Setters and getters
+//
+// While QML code can directly read and write exported fields of Go values, as described
+// above, a Go type can also intercept writes to specific fields by declaring a setter
+// method according to common Go conventions. This is often useful for updating the
+// internal state or the visible content of a Go-defined type.
+//
+// For example:
+//
+//    type Person struct {
+//            Name string
+//    }
+//
+//    func (p *Person) SetName(name string) {
+//            fmt.Println("Old name is", p.Name)
+//            p.Name = name
+//            fmt.Println("New name is", p.Name)
+//    }
+//
+// In the example above, whenever QML code attempts to update the Person.Name field
+// via any means (direct assignment, object declarations, etc) the SetName method
+// is invoked with the provided value instead.
+//
+// A setter method may also be used in conjunction with a getter method rather
+// than a real type field. A method is only considered a getter in the presence
+// of the respective setter, and according to common Go conventions it must not
+// have the Get prefix.
+//
+// Inside QML logic, the getter and setter pair is seen as a single object property.
+//
+//
+// Painting
+//
+// Custom types implemented in Go may have displayable content by defining
+// a Paint method such as:
+//
+//    func (p *Person) Paint(painter *qml.Painter) {
+//            // ... OpenGL calls with the gopkg.in/qml.v1/gl/<VERSION> package ...
+//    }
+//
+// A simple example is available at:
+//
+//   https://github.com/go-qml/qml/tree/v1/examples/painting
+//
+//
+// Packing resources into the Go qml binary
+//
+// Resource files (qml code, images, etc) may be packed into the Go qml application
+// binary to simplify its handling and distribution. This is done with the genqrc tool:
+//
+//   http://gopkg.in/qml.v1/cmd/genqrc#usage
+//
+// The following blog post provides more details:
+//

+These examples were ported from [qtquickcontrols](git@gitorious.org:qt/qtquickcontrols.git).
+
+Only the basic ones were ported, in order to demonstrate how easy it is to create a full-fledged UI with Go and QML.

+There were a few more, but they that had native modules and those were omitted due to laziness.
