+# Release Instructions
+
+This file contains instructions how to publish a Qbs release into various package systems.
+
+## Building packages
+
+Release packages are built automatically by the
+[Build release packages](https://github.com/qbs/qbs/actions/workflows/release.yml) job on GitHub
+actions. The job builds every commit, so you'll need to find a specific run triggered by
+pushing a git tag instead of a commit.
+
+The only interesting artifact is qbs-release-v1.x.y - it contains Windows binary packages as
+well as source packages.
+
+Packages should then be uploaded to the
+[Qt Website](https://download.qt.io/official_releases/qbs/).
+
+## Chocolatey
+
+For updating Qbs in [Chocolatey](https://community.chocolatey.org/packages/qbs), you'll need
+to be a maintainer of the Qbs project. You'll also will need an API key from your
+[account](https://community.chocolatey.org/account) (make sure you have one).
+
+Get the qbs.1.x.y.nupkg file from the qbs-release-v1.x.y.zip archive and run the following command:
+
+```
+choco push --api-key <YOUR_API_KEY> qbs.1.x.y.nupkg"
+```
+
+Choco will upload the file, download binary packages from the Qt Website and publish Qbs
+automatically.
+
+## Homebrew
+
+First, you'll need to [install](https://docs.brew.sh/Installation) Homewbrew.
+
+Second, you'll need to fork the [homebrew-core](https://github.com/Homebrew/homebrew-core) repo
+to you GitHub account.
+
+Next you'll need to add your remote to the existing repo:
+```
+$ brew update
+$ cd "$(brew --repository homebrew/core)"
+$ git remote add github git@github.com:<USERNAME>/homebrew-core.git
+# Create a new git branch for your formula so your pull request is easy to
+# modify if any changes come up during review.
+$ git checkout -b <some-descriptive-name> origin/master
+```
+
+You'll need a SHA-256 sum for the qbs-src-1.x.y.tar.gz source package. SHA-256 sum can be
+found in the sha256sums.txt file from the qbs-release-v1.x.y.zip.
+
+Check if the same upgrade has been already submitted by searching the open pull requests for
+[Qbs](https://github.com/Homebrew/homebrew-core/pulls?q=is%3Apr+is%3Aopen+qbs).
+
+Run the following command, replacing the version and SHA-256 sum:
+```
+$ brew bump-formula-pr --strict qbs \
+    --url https://download.qt.io/official_releases/qbs/1.x.y/qbs-src-1.x.y.tar.gz \
+    --sha256=<SHA-256>
+```
+
+The above can also be done manually by editing the formula source code and creating a pull request.
+
+Some useful commands to build/test formula locally:
+```
+$ brew install --build-from-source qbs
+$ brew test qbs
+$ brew audit --strict qbs
+```
+
+## Mac Ports
+
+Fork [macports-ports](https://github.com/macports/macports-ports) to your GitHub account
+and clone the repo.
+
+Run the following command in the repo dir (must be done only once):
+```
+$ sudo /opt/local/bin/portindex
+```
+
+Make sure that /opt/local/etc/macports/sources.conf contains a line like
+file:///Users/abbapoh/dev/macports-ports [default]
+pointing to your local repo.
+
+Get the qbs-src-1.x.y.tar.gz source package from the archive or from the
+[Qt Website](https://download.qt.io/official_releases/qbs/) and make note of the file size:
+```
+$ ls -l qbs-src-1.x.y.tar.gz
+```
+Get checksums:
+```
+$ openssl sha256 qbs-src-1.x.y.tar.gz
+$ openssl rmd160 qbs-src-1.x.y.tar.gz
+```
+
+Update the devel/qbs/Portfile file with the new url, filesize and checksums.
+
+Build the package:
+```
+$ /opt/local/bin/port lint qbs
+$ sudo /opt/local/bin/port -vst install qbs
+$ /opt/local/bin/qbs --version # Check that this reports the right version
+```
+Commit. Push. Create merge request.

+# General
+
+* A new qbsModuleProviders property was added to Project and Product items which allows
+  to specify which providers will be run (QBS-1604).
+* Added a new library for reading *.pc files which allows to avoid launching multiple pkg-config
+  processes and also gives QBS more information about dependencies between *.pc files (QBS-1615).
+* A new qbspkgconfig provider was added which will replace the fallback provider (QBS-1614).
+  This new provider uses the built-in library and is capable of setting Qt libraries as well.
+* capnproto and protobuf modules can now use runtime provided by the qbspkgconfig provider.
+* A new ConanfileProbe.verbose property was added which can be useful to debug problems with
+  Conan.
+* Qbs no longer migrates the "profiles/" dir from earlier Qbs versions (QTCREATORBUG-26475).
+  Old directories might be cleaned up manually.
+* FileInfo now always uses high-precision timer on all OSes.
+* Fixed a problem with overriding stringList properties in ModuleProviders from command-line.
+
+# C/C++ Support
+
+* Added support for c++23.
+* Add Elbrus E2K architecture for the GCC toolchain (QBS-1675).
+* COSMIC cpp module now avoids using relative file paths as much as possible.
+* Some refactoring was done in the cpp modules to share more code.
+
+# Android Support
+
+* Added Android.ndk.buildId property which allows to overwrite the default value (sha1) for
+  the --build-id linker flag.
+* Fixed reading *.prl files with Qt >= 6.0.
+* Fixed rcc path with Qt >= 6.2.
+
+# Documentation
+
+* Added a new page with the list of ModuleProviders.
+* Qt provider now has its own page.
+* Clarified that application won't be runnable by default, unless env or rpaths are set correctly.
+
+# Infrastructure
+
+* Added standalone job for building documentation.
+* Xcode version was bumped to 12.5.1.
+* Added OpenSUSE Leap docker image.
+* Added Android tests with different NDK versions.
+* Fixed QMake build with Qt 6.

+# General
+* A new Host service was introduced, providing information about the host system that
+  used to be available from the qbs module, but did not really belong there.
+  In addition, some more qbs module properties have moved to the FileInfo service.
+* The product variable in Export items now points to the importing product, rather than
+  the exporting one.
+* Probes are now also available in ModuleProvider items.
+
+# C/C++ Support
+* Added support for the Open Watcom toolchain.
+* Reduced unneeded re-linking on Linux by ignoring changes to weak symbols in library
+  dependencies by default.
+
+# Qt Support
+* Android multi-arch packages are supported again wth Qt >= 6.3.
+* We now use cpp.systemIncludePaths for Qt headers, so that building Qt applications
+  no longer triggers warnings from Qt headers unrelated to the user code.
+
+# Infrastructure
+* Added coverage for Digital Mars compiler.
+* Added coverage for static Qt builds.

+
+    \section2 \c base
+    This value is useful when making use of inheritance. It stands for the value of the respective
+    property in the item one level up in the inheritance chain. For instance:
+    \code
+    Product { // defined in MyProduct.qbs
+        Depends { name: "mymodule" }
+        mymodule.someProperty: ["value1"]
+    }
+    ------ some other file ------
+    MyProduct {
+        mymodule.someProperty: base.concat(["value2"]) // => ["value1", "value2"]
+    }
+    \endcode
+
+    \section2 \c exportingProduct
+    Within an \l Export item, you can use the \c exportingProduct variable to refer to
+    the product which defines the Export item:
+
+    \code
+    Product {
+        Export {
+            Depends { name: "cpp" }
+            cpp.includePaths: exportingProduct.sourceDirectory
+        }
+    }
+    \endcode
+
+    \section2 \c filePath
+
+    This value holds the full file path to the \c .qbs file it appears in. This property is
+    rarely used, but might be useful when debugging:
+    \code
+    Product {
+        property bool dummy: {
+            console.info("I'm located at " + filePath);
+        }
+    }
+    \endcode
+
+    \section2 \c importingProduct
+    Within an \l Export item, you can use the \c importingProduct variable to refer to
+    the product that pulls in the resulting module:
+
+    \code
+    Product {
+        Export {
+            Depends { name: "cpp" }
+            cpp.includePaths: importingProduct.buildDirectory
+        }
+    }
+    \endcode
+    Usually, you should use the \l product variable instead for consistency with \l Module items.
+
+    \section2 \c original
+    On the right-hand side of a module property binding, this refers to the value of the property
+    in the module itself (possibly overridden from a profile). Use it to set a module property
+    conditionally:
+    \code
+    Module { // This is mymodule
+        property string aProperty: "z"
+    }
+    ----------
+    Product {
+        Depends { name: "mymodule" }
+        Depends { name: "myothermodule" }
+        // "y" if myothermodule.anotherProperty is "x", "z" otherwise:
+        mymodule.aProperty: myothermodule.anotherProperty === "x" ? "y" : original
+    }
+    \endcode
+
+    \section2 \c outer
+    This value is used in nested items, where it refers to the value of the respective property
+    in the surrounding item. It is only valid in \l{Group} and \l{Properties} items:
+    \code
+    Product {
+        Depends { name: "mymodule" }
+        mymodule.someProperty: ["value1"]
+        Group {
+            name: "special files"
+            files: ["somefile1", "somefile2"]
+            mymodule.someProperty: outer.concat(["value"]) // => ["value1", "value2"]
+        }
+    }
+    \endcode
+
+    \section2 \c path
+
+    This value holds the path to the folder where the \c .qbs file is located. Use it to e.g. add
+    the product's directory to file paths:
+    \code
+    Product {
+        Depends { name: "cpp" }
+        cpp.includePaths: path
+    }
+    \endcode
+
+    \section2 \c product
+
+    This value holds the properties of the product that contains the current item or pulls in the
+    current module:
+    \code
+    Module {
+        Rule {
+            Artifact {
+                fileTags: product.type
+                filePath: {
+                    var result = input.fileName;
+                    // module properties are available as well
+                    if (product.qbs.buildVariant === "debug")
+                        result = result + "_debug";
+                    result = result + ".out";
+                    return result;
+                }
+            }
+        }
+    }
+    \endcode
+    Within the \l Export item, same as \l importingProduct.
+
+    \section2 \c project
+    This value holds the properties of the project that references the current item or pulls in the
+    current module:
+    \code
+    Project {
+        property bool enableProduct: true
+        Product {
+            name: "theProduct"
+            condition: project.enableProduct
+        }
+    }
+    \endcode
+    If the nearest project in the project tree does not have the desired property, \QBS looks it
+    up in the parent project, potentially all the way up to the top-level project.

-    \section1 Special Property Values
-
-    For every property defined in a module, \QBS provides the following special
-    built-in values:
-
-    \list
-        \li \l base
-        \li \l original
-        \li \l outer
-    \endlist
-
-    \section2 \c base
-    This value is useful when making use of inheritance. It stands for the value of the respective
-    property in the item one level up in the inheritance chain. For instance:
-    \code
-    Product { // defined in MyProduct.qbs
-        Depends { name: "mymodule" }
-        mymodule.someProperty: ["value1"]
-    }
-    ------ some other file ------
-    MyProduct {
-        mymodule.someProperty: base.concat(["value2"]) // => ["value1", "value2"]
-    }
-    \endcode
-
-    \section2 \c original
-    This is the value of the property in the module itself (possibly overridden from a profile or
-    the command line). Use it to set a module property conditionally:
-    \code
-    Module { // This is mymodule
-        property string aProperty: "z"
-    }
-    ----------
-    Product {
-        Depends { name: "mymodule" }
-        Depends { name: "myothermodule" }
-        mymodule.aProperty: myothermodule.anotherProperty === "x" ? "y" : original // => "y" if myothermodule.anotherProperty is "x", "z" otherwise
-    \endcode
-
-    \section2 \c outer
-    This value is used in nested items, where it refers to the value of the respective property
-    in the surrounding item. It is only valid in \l{Group} and \l{Properties} items:
-    \code
-    Product {
-        Depends { name: "mymodule" }
-        mymodule.someProperty: ["value1"]
-        Group {
-            name: "special files"
-            files: ["somefile1", "somefile2"]
-            mymodule.someProperty: outer.concat(["value"]) // => ["value1", "value2"]
-        }
-    }
-    \endcode
+    \section2 Special Property Values
 
+    For every property defined in a module, \QBS provides the special
+    \l{Special Property Values#original}{original} value containing the value of the property in
+    the module itself (possibly overridden from a profile).

+    \qmltype Exporter.cmake
+    \inqmlmodule QbsModules
+    \since Qbs 2.3
+
+    \brief Provides support for generating \CMAKE packages from dynamic, static and header library
+    products.
+
+    The Exporter.cmake module contains the properties and rules to create a \CMAKE config
+    \l{https://cmake.org/cmake/help/v3.29/manual/cmake-packages.7.html#config-file-packages}{files}
+    from the \l Export item of a \l Product.
+
+    For instance, suppose you are creating a library. To allow exporting to \CMAKE, you would write
+    something like the following:
+    \code
+    DynamicLibrary {
+        name: "mylibrary"
+        qbs.installPrefix: "/opt/mylibrary"
+        Depends { name: "Exporter.cmake" }
+        Exporter.cmake.packageName: "MyLibrary"
+        property string headersInstallDir: "include"
+        // ...
+        Group {
+            name: "API headers"
+            files: ["mylib.h"]
+            qbs.install: true
+            qbs.installDir: headersInstallDir
+        }
+        Group {
+            fileTagsFilter: ["Exporter.cmake.package"]
+            qbs.installDir: "lib/cmake/MyLibrary"
+        }
+        Export {
+            Depends { name: "cpp" }
+            cpp.includePaths: FileInfo.joinPaths(
+                exportingProduct.qbs.installRoot,
+                exportingProduct.qbs.installPrefix,
+                exportingProduct.headersInstallDir)
+        }
+    }
+    \endcode
+    To build against this library, from within your \CMAKE project, you simply
+    use \l{https://cmake.org/cmake/help/v3.29/command/find_package.html}{find_package}:
+    \code
+        find_package(MyLibrary PATHS REQUIRED)
+        add_executable(Consumer main.cpp)
+        target_link_libraries(Consumer MyLibrary)

+
+    \title Application
+
+    Let's start with a mandatory Hello World example. There is a Hello World example in the
+    \l{overview.html#well-defined-language}{overview section}, but this time we will create a
+    real-world project.
+
+    We will start with a simple \QBS project file:
+    \snippet ../tutorial/chapter-1/myproject.qbs 0
+
+    Here, we set the \l{Project::name}{name} of the project to \c "My Project" - it is mainly
+    used for IDEs but can also be used to reference a project when setting properties from
+    command-line. We also set the \l{Project::minimumQbsVersion}{minimumQbsVersion} - this property
+    can be useful if the project depends on features that are not present in earlier \QBS
+    versions.
+
+    The \l{Project::references}{references} property contains the path to a file
+    that describes our application. This file is located in a separate \c app directory -
+    typically, projects tend to have quite a complicated structure but \QBS does not enforce any
+    specific layout, so we will simply put each product in a separate directory.
+
+    The application file sets several properties:
+    \snippet ../tutorial/chapter-1/app/app.qbs 0
+
+    The \l{Product::name}{name} property identifies the product.
+    The \l{Product::targetName}{targetName} property sets the name of the resulting binary
+    (without the \c .exe extension on Windows, which is appended automatically). By default,
+    \l{Product::targetName}{targetName} defaults to \l{Product::name}{name}. The
+    \l{Product::files}{files} property contains a single \c main.c file which is a trivial
+    \e{hello world} application:
+    \snippet ../tutorial/chapter-1/app/main.c 0
+
+    We set \l{Product::consoleApplication}{consoleApplication} to \c true to indicate that our
+    application is going to be used from a terminal. For example, on Windows, this will spawn a
+    new console window if you double-click the resulting binary, while on macOS it will create a
+    standalone binary file instead of an
+    \l{https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html}{application bundle}.
+
+    By default, the \l{Application::install}{CppApplication.install} property is \c false and thus
+    \QBS does not install the binary. If the \l{Application::install}{install} property is
+    \c true, when building a project, \QBS will also install it into an \e{installation root}
+    folder which by default is named \c install-root and located under the build directory. This
+    folder will contain only resulting artifacts without the build leftovers and files will have
+    the same layout as in the target system. The \l{Application::install}{install} property should
+    be set to \c true for all products that are to be distributed.
+    See the \l{installing-files.html}{Installing Files} section for more details.
+
+    We can now build and run our application from the project directory:
+    \code
+    chapter-1 $ qbs build
+    ...
+    Building for configuration default
+    compiling main.c [My Application]
+    ...
+    linking myapp [My Application]
+    ...
+    Build done for configuration default.
+
+    chapter-1 $ qbs run
+    ...
+    Starting target. Full command line: .../default/install-root/usr/local/bin/myapp
+    Hello, world
+    \endcode
+
+    The \QBS output to console and default installation location may vary between different
+    platforms.
+
+    In most cases, \QBS should be able to find the default compiler (for example, GCC or
+    Clang on Linux, Visual Studio on Windows, or Xcode on macOS), but if that's not the
+    case, see the \l{configuring.html}{configuring} section.
+
+    In the following chapters, we will continue to improve our project: we will add a library and
+    make it configurable.

+
+/*!
+    \previouspage tutorial-1.html
+    \page tutorial-2.html
+    \nextpage tutorial-3.html
+
+    \title Static Library
+
+    Let's add a static library to our project so we can reuse some code. Analogous to what we did
+    for the application, we put the file into the \c{lib} directory and add it to the
+    \l{Project::references}{references} property in our project. The modified project may look
+    like this:
+
+    \snippet ../tutorial/chapter-2/myproject.qbs 0
+
+    Let's take a look at the the library file now:
+
+    \snippet ../tutorial/chapter-2/lib/lib.qbs 0
+    It contains the \l{StaticLibrary} item which sets the \l{Product::type}{type} of the product
+    to \c "staticlibrary" and sets some defaults like where to install that library.
+    As before, we set the \l{Product::files}{files} property with a header:
+    \snippet ../tutorial/chapter-2/lib/lib.h 0
+    And we set the implementation file of our library:
+    \snippet ../tutorial/chapter-2/lib/lib.c 0
+
+    We will keep our library really simple - it only contains one function, which we will later use
+    in our application. The source file requires a \c "CRUCIAL_DEFINE" to be
+    passed to a preprocessor. That is why we set the \l{cpp::defines}{cpp.defines} property:
+    \snippet ../tutorial/chapter-2/lib/lib.qbs 1
+
+    Note that unlike the \l{CppApplication} item, the \l{StaticLibrary} does not pull in the
+    dependency on the \l{cpp} module automatically - that is why we have to pull it in manually
+    using the \l{Depends} item. Without the \l{cpp} module, \QBS would not know how to turn a
+    \c{.c} file into an object file and the object file into a library. See
+    \l{Rules and Product Types} for details.
+
+    Next, we need to tell \QBS where to look for public headers of our library when building
+    products that depend on it. By default, \QBS knows nothing about the layout of our
+    library, so we tell it to look for headers in the library's source directory using the
+    \l{Export} item:
+
+    \snippet ../tutorial/chapter-2/lib/lib.qbs 2
+    You can export any \l{Module} property within the \l{Export} item - it will be merged in the
+    depending product with other properties. For example, you can export
+    \l{cpp::defines}{cpp.defines} or specific \l{cpp::commonCompilerFlags}{compiler flags} that
+    are required to use this product.
+
+    We depend on the \l{cpp} module twice - once within the \l{StaticLibrary}
+    item and once in the \l{Export} item. This is because by default \QBS does not export anything
+    when depending on this product and the dependencies in this item (as well as
+    properties set in this item) are private to this product while dependencies and properties
+    set in the \l{Export} item are for export only.
+
+    Finally, we have some Apple-specific settings. You can skip this part of the tutorial if you
+    are using some other platform. We depend on the \l{bundle} module and set the
+    \l{bundle::isBundle}{bundle.isBundle} to false:
+    \snippet ../tutorial/chapter-2/lib/lib.qbs 3
+    By default, \QBS builds static and dynamic libraries as
+    \l{https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WhatAreFrameworks.html}{Frameworks}
+    on macOS. So, to keep things simple, we disable the framework build and build a plain old
+    static library file here.

+
+/*!
+    \previouspage tutorial-2.html
+    \page tutorial-3.html
+    \nextpage tutorial-4.html
+
+    \title Dynamic Library
+
+    Let's now turn our static library into a dynamic library. It is a bit trickier with dynamic
+    libraries since several things should be tweaked. First, we need to be able to mark methods
+    (or classes) in our library as exported. Second, we need to tell our application where to look
+    for our library at run time using \l{https://en.wikipedia.org/wiki/Rpath}{rpaths}.
+
+    Some compilers, like MSVC, require us to mark which symbols we want to export or import. The
+    \l{https://stackoverflow.com/a/6840659}{canonical} way would be to define some helper macros.
+    Let's start with a header that defines those helper macros:
+    \snippet ../tutorial/chapter-3/lib/lib_global.h 0
+
+    This header defines the \c MYLIB_EXPORT macro that expands either to an "export" or to an
+    "import" directive based on the presence of the \c MYLIB_LIBRARY macro. We can use this macro
+    to mark a function as follows:
+    \snippet ../tutorial/chapter-3/lib/lib.h 0
+
+    The modified library product may look like this:
+
+    \snippet ../tutorial/chapter-3/lib/lib.qbs 0
+
+    The most important change is that we changed the item type from \l{StaticLibrary} to
+    \l{DynamicLibrary}. We also added the \c MYLIB_LIBRARY to the list of
+    \l{cpp::defines}{defines}. We do this only when building the library but we are not exporting
+    it - that way the users of our library will have methods marked for import rather than export.
+
+    Finally, we set \l{cpp::sonamePrefix}{cpp.sonamePrefix} to \c "@rpath". This is required only
+    for Apple platforms, see
+    \l{https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/DynamicLibraries/100-Articles/RunpathDependentLibraries.html}{Run-Path Dependent Libraries}
+    for details.
+
+    It is also required to set \l{cpp::rpaths}{cpp.rpaths} in our application file. Since the
+    library is installed to the \c{lib} directory and the application is installed to the \c{bin}
+    directory, we need to tell the loader to look in the \c{lib} directory. The
+    \l{jsextension-fileinfo.html#relativePath}{FileInfo.relativePath} method can help us:
+    \snippet ../tutorial/chapter-3/app/app.qbs 0
+
+    On Linux, this expression would be equivalent to this: \c{cpp.rpaths: ["$ORIGIN/../lib"]}.
+    Don't forget to \c{import qbs.FileInfo} in order to be able to use the
+    \l{jsextension-fileinfo.html} extension.
+
+    To make the example complete, here's how the full \c app/app.qbs file should look like:
+    \snippet ../tutorial/chapter-3/app/app.qbs 1

+
+    \title Convenience Items
+
+    As you might have noticed, we are repeating ourselves when setting the same properties in our
+    products - we set \l{Product::version}{version}, \l{Application::install}{install},
+    \l{cpp::rpaths}{cpp.rpaths}, and so on. For a single application and a library, that is not a
+    big deal, but what if we have a dozen libraries? Luckily, this can be achieved using item
+    \l{language-introduction.html#reusing-project-file-code}{inheritance} - we move the common code
+    to the base item and in the real product we will only set what is specific to that product (for
+    example, the list of \l{Product::files}{files}).
+
+    First, we need to tell \QBS where to look for our new base items. This can be achieved using
+    the \l{Project::qbsSearchPaths}{qbsSearchPaths} property. We set this property to \c "qbs" so
+    that \QBS will search our items in the \c{qbs} directory located in the project directory:
+    \snippet ../tutorial/chapter-4/myproject.qbs 0
+
+    \note This directory has a pre-defined structure: base items should be located under the
+    \c{imports} subdirectory. See \l{Custom Modules and Items} for details.
+
+    Let's create a base item for all our applications and move common code there:
+    \snippet ../tutorial/chapter-4/qbs/imports/MyApplication.qbs 0
+
+    As you see, we managed to extract most of the code here, and our application file now only
+    contains what's relevant to it:
+    \snippet ../tutorial/chapter-4/app/app.qbs 0
+
+    Now let's do the same for our library:
+    \snippet ../tutorial/chapter-4/qbs/imports/MyLibrary.qbs 0
+
+    Here, we introduce a helper property, \c libraryMacro, with a default value calculated based
+    on the capitalized product name. Since the name of out library product is \c "mylib", this
+    property will expand to \c "MYLIB_LIBRARY". We can also override the default value
+    for the macro in products that inherit our item like this:
+    \code
+    MyLibrary {
+        libraryMacro: "SOME_OTHER_LIBRARY_MACRO"
+    }
+    \endcode
+
+    Let's take a look at the refactored library file:
+    \snippet ../tutorial/chapter-4/lib/lib.qbs 0
+
+    We managed to extract the reusable parts to common base items leaving the actual products clean
+    and simple.
+
+    Unfortunately, item inheritance comes with a price - when both parent and child items set the
+    same property (\l{cpp::defines}{cpp.defines} in our case), the value in the child item wins.
+    To work around this, the special \l{special-property-values.html#base}{base} value
+    exists - it gives access to the base item's value of the current property and makes it possible
+    to extend its value rather than override it. Here, we concatenate the list of defines from the
+    base item \c{["MYLIB_LIBRARY"]} with a new list, specific to this product (namely,
+    \c{['CRUCIAL_DEFINE']}).
+*/
+
+/*!
+    \previouspage tutorial-4.html
+    \page tutorial-5.html
+    \nextpage tutorial-6.html
+
+    \title Autotest
+
+    Now that we can re-use our base items, let's add a simple autotest. We inherit the new item
+    from the \c MyApplication item and add an \c "autotest" type:
+
+    \snippet ../tutorial/chapter-5/qbs/imports/MyAutoTest.qbs 0
+
+    This additional type is required for the helper \l{AutotestRunner} item. This item runs all
+    products with the \c "autotest" type when it is being built. It also implicitly depends on all
+    such products, so they will be built before running as well.
+
+    Let's add this item to our top-level \l{Project} item:
+
+    \code
+    Project {
+        name: "My Project"
+        minimumQbsVersion: "2.0"
+        // ...
+        AutotestRunner {
+            timeout: 60
+        }
+    }
+    \endcode
+    Here we set the \l{AutotestRunner::timeout}{timeout} property to 60 seconds so that our runner
+    kills tests that run way too long.
+
+    Now we need to add our first test. Let's create a new product with the following content:
+
+    \snippet ../tutorial/chapter-5/test/test.qbs 0
+
+    Here we depend on our library (which we are going to test), set the product
+    \l{Product::name}{name}, and specify the source file, which looks like this:
+    \snippet ../tutorial/chapter-5/test/test.c 0
+
+    The test compares the value from the library with the value from the command line.
+
+    Don't forget to add the new test product to the references property in the Project:
+    \snippet ../tutorial/chapter-5/myproject.qbs 0
+
+    Now we can build the autotest product - this will also launch our test:
+    \code
+    $ qbs build -p "autotest-runner"
+    ...
+    running test mytest [autotest-runner]
+    Build done for configuration default.
+    \endcode
+*/
+
+/*!
+    \previouspage tutorial-5.html
+    \page tutorial-6.html
+    \nextpage tutorial-7.html
+
+    \title Project Properties
+
+    It would be nice if our project was configurable. Let's add some properties to our root project
+    file:
+    \snippet ../tutorial/chapter-6/myproject.qbs 0
+
+    Now we can use those properties in our helper items and in products:
+
+    \snippet ../tutorial/chapter-6/qbs/imports/MyApplication.qbs 0
+
+    Here, we access the project file using the special
+    \l{special-property-values.html#project}{project} value. If the nearest project in the project
+    tree does not have the desired property, \QBS looks it up in the parent project, potentially
+    all the way up to the top-level project.
+    We also use the \l{Application::installDebugInformation}{installDebugInformation}
+    property here. By default, it has the same value as \l{Application::install}{install} but we
+    want to make the debug information install optional.
+
+    Let's now disable the tests if \c project.withTests is \c false:
+
+    \snippet ../tutorial/chapter-6/myproject.qbs 1
+
+    Here we use the \l{Properties} item within the \l{SubProject} item. This item allows to
+    override a subproject's properties which can be useful when adding some other \QBS project as a
+    Git submodule. Of course, it is not very useful in our particular case since we only set the
+    \l{Project::condition}{Project.condition} property. We could achieve the same effect by
+    setting the \l{SubProject::condition}{condition} property of the \l{SubProject} item:
+    \code
+        SubProject {
+            filePath: "test/test.qbs"
+            condition: parent.withTests
+        }
+    \endcode
+    Another way would be to disable the test product. That way, an IDE would still show the whole
+    project tree including disabled tests:
+    \code
+        // qbs/imports/MyAutoTest.qbs
+        MyApplication {
+            condition: project.withTests
+            type: base.concat(["autotest"])
+        }
+    \endcode
+
+    Let's finally make our \l{AutotestRunner} configurable too:
+    \snippet ../tutorial/chapter-6/myproject.qbs 2
+
+    There are several ways to override project properties from the command line. First, the special
+    \c project variable can be used to set the properties of the top-level project:
+    \code
+        $ qbs resolve project.withTests:false
+    \endcode
+
+    You can also refer to properties using project's \l{Project::name}{name}:
+
+    \code
+        $ qbs resolve "projects.My Project.withTests:false"
+    \endcode
+
+    This can again be useful for accessing the properties of external sub-projects. Note that since
+    the project name contains spaces, we use quotes here.

+
+    \title Buildconfig Module
+
+    In the previous chapter, we added some properties to our main \l{Project} file. While this is a
+    perfect approach for \e public properties of the project, sometimes we want
+    to add some \e private properties for better tuning. Of course, we could put everything
+    in the \l{Project} file, but that would make it very convoluted. Also, accessing the top-level
+    project all the way from products makes things strongly tied.
+
+    You can also use a \l{Module} that \l{Product}{products} may depend on. That way, a
+    \l{Product} only uses properties of the module it depends on without the need to know about
+    the top-level project.
+
+    Let's create a file named \c{mybuildconfig.qbs} and put it into the
+    \c{qbs/modules/mybuildconfig} directory, near the \c{qbs/imports} directory:
+    \code
+        // qbs/modules/mybuildconfig.qbs
+        Module {
+        }
+    \endcode
+
+    So far, this is just an empty \l{Module} so let's add some properties to it:
+    \snippet ../tutorial/chapter-7/qbs/modules/mybuildconfig/mybuildconfig.qbs 0
+
+    We added the \c appInstallDir and \c libInstallDir properties that will allow us to configure
+    the installation location of the our application and library, respectively.
+
+    Now we can use our module in the \c{MyApplication.qbs} item:
+    \snippet ../tutorial/chapter-7/qbs/imports/MyApplication.qbs 0
+
+    We pull in the new module using the \l{Depends} item, similar to how we pulled in
+    the \l{cpp} module dependency earlier. We also set the \l{Application::installDir}{installDir}
+    property to the corresponding module property, namely to \c{mybuildconfig.appInstallDir}.
+
+    \QBS \l{Module}{modules} have the feature to automatically export properties of other modules.
+    Those exported properties are merged in the resulting product. We can use this feature to set
+    the \l{cpp::rpaths}{cpp.rpaths} in our module rather than in products:
+
+    \snippet ../tutorial/chapter-7/qbs/modules/mybuildconfig/mybuildconfig.qbs 1
+
+    Here, we inject the dependency on the \l{cpp} module and calculate the \c{libRPaths} property.
+    This is a relative path from the \c{product.installDir} (which is either \c{"bin"}
+    or \c{"lib"}, depending on product type to \c{libInstallDir}). Finally, we set
+    \l{cpp::rpaths}{cpp.rpaths} to this property. This way, those \c rpaths will be automatically
+    exported to all products that depend on the \c{mybuildconfig} module.
+
+    Now, we can also use our new module in the library item:
+    \snippet ../tutorial/chapter-7/qbs/imports/MyLibrary.qbs 0
+
+    Let's change the library folder name from \c{"lib"} to \c{"lib64"} when building our project:
+    \code
+        $ qbs modules.mybuildconfig.libDirName:lib64
+        ...
+        $ ls default/install-root/usr/local/
+        bin    lib64

+
+    \title Configurable Library
+
+    In this chapter, we will make our library more configurable. We will add configuration options
+    to be able to choose between static and dynamic builds.
+
+    We start with some new properties in the \c mybuildconfig module:
+    \code
+    Module {
+        ...
+        property bool staticBuild: false
+        property bool installStaticLib: true
+        ...
+    }
+    \endcode
+
+    We need to do some modifications to export macros in the \c lib/lib_global.h header:
+    \snippet ../tutorial/chapter-8/lib/lib_global.h 0
+
+    Here' we added a new branch when \c MYLIB_STATIC_LIBRARY is defined. In that case, we make
+    the \c MY_LIB_EXPORT macro empty.
+
+    Now, let's modify the \c qbs/imports/MyLibrary.qbs file as follows:
+    \snippet ../tutorial/chapter-8/qbs/imports/MyLibrary.qbs 0
+
+    First thing to notice is that we changed the type of the item from \l{DynamicLibrary} to the
+    \l{Library} item which is a common base item for dynamic and static libraries.
+
+    Second, we change the \l{Product::type}{type} of the product so it depends on the \c staticBuild
+    property:
+    \code
+    type: mybuildconfig.staticBuild ? "staticlibrary" : "dynamiclibrary"
+    \endcode
+
+    Third, we change our \e{export macro} to be different in the static and dynamic builds to
+    correspond with the changes we made to the \c lib_global.h:
+    \code
+    readonly property string _nameUpper : name.replace(" ", "_").toUpperCase()
+    property string libraryMacro: _nameUpper + "_LIBRARY"
+    property string staticLibraryMacro: _nameUpper + "_STATIC_LIBRARY"
+    cpp.defines: mybuildconfig.staticBuild ? [staticLibraryMacro] : [libraryMacro]
+    \endcode
+
+    Note that in a static build we export the \c MYLIB_STATIC_LIBRARY macro so that the dependent
+    products will know whether they link to a static or dynamic library:
+    \code
+    Export {
+        ...
+        cpp.defines: exportingProduct.mybuildconfig.staticBuild
+            ? [exportingProduct.staticLibraryMacro] : []
+    }
+    \endcode
+
+    Now we can build our project in dynamic or static mode:
+    \code
+    $ qbs resolve modules.mybuildconfig.staticBuild:false && qbs build
+    ...
+    $ ls default/install-root/usr/local/lib/
+        libmylib.1.0.0.so
+        libmylib.1.0.so
+        libmylib.1.so
+        libmylib.so
+    $ rm -r default
+    $ qbs resolve modules.mybuildconfig.staticBuild:true && qbs build
+    ...
+    $ $ ls default/install-root/usr/local/lib/
+        libmylib.a
+    \endcode

+    \previouspage tutorial-8.html
+    \page tutorial-9.html
+    \nextpage howtos.html
+
+    \title Version Header
+
+    To create new files, such as version headers, during the build, use \l{Rules}. Every command
+    \QBS executes, such as compile or linker commands, is described by a corresponding Rule in a
+    Module or a Product.
+
+    In this section, we will create a simple header with a string constant based on the variable
+    in our project.
+
+    First, we add this variable to our \c mybuildconfig module:
+    \snippet ../tutorial/chapter-9/qbs/modules/mybuildconfig/mybuildconfig.qbs 0
+
+    Next, we create a new file, \c{version.h.in}, located in the \c{version-header} directory. This
+    file contains the template for our header:
+    \snippet ../tutorial/chapter-9/version-header/version.h.in 0
+
+    Now we create a file called \c{version-header.qbs} in the same directory. This file contains
+    a \l{Product} with a \l{Rule} that turns the \c{version.h.in} into a real header.
+    Let's go through the contents of the file:
+    \snippet ../tutorial/chapter-9/version-header/version-header.qbs 0
+
+    First, we import \l{TextFile Service}{TextFile}. We will need this class to read the template
+    and write the resulting header. Second, we declare a new \l{Product} named \c{"version_header"}
+    and with the \c{"hpp"} type. This is the type of the artifact we will create in the Rule.
+    Third, we add the dependency on the \c mybuildconfig module to use the new
+    \c mybuildconfig.productVersion variable.
+
+    We also add a \l{Group} with the template file and assign the \c{version_h_in} tag to the file:
+    \snippet ../tutorial/chapter-9/version-header/version-header.qbs 1
+
+    \QBS Rules work with file tags, instead of working with files directly, which makes
+    it easy to reuse rules. The name of the tag is chosen arbitrarily here. We could use the name
+    of the file as a tag, but to avoid confusion between file name and file tag, we use underscores
+    in the tag instead of dots.
+
+    Now we can create a Rule itself:
+    \snippet ../tutorial/chapter-9/version-header/version-header.qbs 2
+    Here, we specify that our Rule takes files tagged as \c "version_h_in" and produces an
+    \l{Artifact} with the name \c "version.h" and tagged \c "hpp". By default, files are created in
+    the \l{Product::destinationDirectory}{Product.destinationDirectory} folder. We add the \c "hpp"
+    tag for the header as this is the tag the \l{cpp}{cpp module} uses for headers. That way, \QBS
+    can track changes and process our generated file the same way it treats all other
+    headers. Note that earlier we set the product type to \c "hpp" as well. \QBS requires that
+    artifact type should match the product type directly or be accessible via the chain of Rules.
+    Otherwise, the Rule won't be executed. For details, see the \l{Rules and Product Types}
+    section.
+
+    The actual code generation happens in the \l{Rule::prepare}{Rule.prepare} script:
+    \snippet ../tutorial/chapter-9/version-header/version-header.qbs 3
+
+    In this script, we create a \l {JavaScriptCommand} object and set some meta properties, such as
+    the description and highlight. For details about Commands, see
+    \l{Command and JavaScriptCommand}. In the sourceCode variable, we create a JavaScript
+    function that opens the \l{The inputs and outputs Variables}{input file}, reads its content
+    using the \l{TextFile Service}{TextFile} object, replaces the \c "${PRODUCT_VERSION}"
+    placeholder with the actual value in the \c product.mybuildconfig.productVersion variable, and
+    writes the resulting content into the \l{The inputs and outputs Variables}{output file}.
+
+    Finally, we export the \l{Product::buildDirectory}{exportingProduct.buildDirectory} so that
+    products that depend on this product can include our generated header:
+
+    \snippet ../tutorial/chapter-9/version-header/version-header.qbs 4
+
+    The full content of the file should look like this:
+
+    \snippet ../tutorial/chapter-9/version-header/version-header.qbs 5
+
+    Let's now add our Product into the root project so \QBS will be aware of it:
+    \snippet ../tutorial/chapter-9/myproject.qbs 0
+
+    We also need to add the dependency on the \c "version_header" to our application:
+    \snippet ../tutorial/chapter-9/app/app.qbs 0
+
+    Now we can include the header in the \c main.c file and print the contents of the string
+    constant:
+
+    \snippet ../tutorial/chapter-9/app/main.c 0
+
+    Let's try and run our application. You should see something like this:
+    \code
+    $ qbs run -p "My Application"
+    Starting target. Full command line: .../default/install-root/usr/local/bin/myapp
+    Hello, world
+    Hello from library
+    ProductVersion = 1.0.0
+    \endcode

+If zero or one commits are given, run clang-format on all lines that differ

+
+  To also format everything touched in the most recent commit:
+    git clang-format HEAD~1

-"""biplist -- a library for reading and writing binary property list files.
-
-Binary Property List (plist) files provide a faster and smaller serialization
-format for property lists on OS X. This is a library for generating binary
-plists which can be read by OS X, iOS, or other clients.
-
-The API models the plistlib API, and will call through to plistlib when
-XML serialization or deserialization is required.
-
-To generate plists with UID values, wrap the values with the Uid object. The
-value must be an int.
-
-To generate plists with NSData/CFData values, wrap the values with the
-Data object. The value must be a string.
-
-Date values can only be datetime.datetime objects.
-
-The exceptions InvalidPlistException and NotBinaryPlistException may be 
-thrown to indicate that the data cannot be serialized or deserialized as
-a binary plist.
-
-Plist generation example:
-    
-    from biplist import *
-    from datetime import datetime
-    plist = {'aKey':'aValue',
-             '0':1.322,
-             'now':datetime.now(),
-             'list':[1,2,3],
-             'tuple':('a','b','c')
-             }
-    try:
-        writePlist(plist, "example.plist")
-    except (InvalidPlistException, NotBinaryPlistException), e:
-        print "Something bad happened:", e
-
-Plist parsing example:
-
-    from biplist import *
-    try:
-        plist = readPlist("example.plist")
-        print plist
-    except (InvalidPlistException, NotBinaryPlistException), e:
-        print "Not a plist:", e

+//             The "cpp" part of this binding is represented by an ItemValue whose
+//             item is of type ModuleInstancePlaceholder, originally set up by ItemReaderASTVisitor.
+//             This function will be called with the actual cpp module item and will
+//             replace the placeholder item in the item value. It will also return
+//             the placeholder item for subsequent merging of its properties with the
+//             ones of the actual module (in ModulePropertyMerger::mergeFromLocalInstance()).
+//             If there were no cpp property bindings defined in Qt.core, then we'd still
+//             have to replace the placeholder item, because references to "cpp" on the
+//             right-hand-side of other properties must refer to the module item.
+//             This is the common use of this function as employed by resolveProdsucDependencies().
+//             Note that if a product has dependencies on more than one variant of a multiplexed
+//             product, these dependencies are competing for the item value property name,
+//             i.e. this case is not properly supported by the syntax. You must therefore not
+//             export properties from multiplexed products that will be different between the
+//             variants. In this function, the condition manifests itself by a module instance
+//             being encountered instead of a module instance placeholder, in which case
+//             nothing is done at all.
+// Use case 2: We inject a fake qbs module into a project item, so qbs properties set in profiles
+//             can be accessed in the project level. Doing this is discouraged, and the
+//             functionality is kept mostly for backwards compatibility. The moduleItem
+//             parameter is null in this case, and the item will be created by the function itself.
+// Use case 3: A temporary qbs module is attached to a product during low-level setup, namely
+//             in product multiplexing and setting qbs.profile.
+// Use case 4: Module propagation to the the Group level.
+// In all cases, the first returned item is the existing one, and the second returned item
+// is the new one. Depending on the use case, they might be null and might also be the same item.

+// while in the Qt.widgets module, it will look like this:
+//   cpp.defines: "QT_WIDGETS_LIB"
+// A product with a dependency on both these modules will end up with a value of
+// ["QT_WIDGETS_LIB", "QT_CORE_LIB"], plus potentially other defines set elsewhere.
+// Each of these values is assigned a priority that roughly corresponds to the "level" at which
+// the module containing the property binding resides in the dependency hierarchy.
+// For list properties, the priorities determine the order of the respecive values in the
+// final array, for scalar values they determine which one survives. Different scalar values
+// with the same priority trigger a warning message.
+// Since the right-hand side of a binding can refer to properties of the surrounding context,
+// each such value gets its own scope.
+
+// This function is called when a module is loaded via a Depends item.
+// loadingItem is the product or module containing the Depends item.
+// loadingName is the name of that module. It is used as a tie-breaker for list property values
+//             with equal priority.
+// localInstance is the module instance placeholder in the ItemValue of a property binding,
+//               i.e. the "cpp" in "cpp.defines".
+// globalInstance is the actual module into which the properties from localInstance get merged.
