    \qmltype qbs
    \inqmlmodule QbsModules
    \since Qbs 1.0

    \brief Comprises general properties.

    The \c qbs module is implicitly loaded in every product. It contains properties of the current
    build environment, independent of the used programming languages and toolchains.

    \section2 Installation Properties

    Typically, you use \l{Group} items to specify the target directories for
    installing files. To install a group of files, set the \l{qbs::install}
    {qbs.install} property of the Group to \c true. The value of
    \l{qbs::installDir}{qbs.installDir} specifies the path to the directory
    where the files will be installed. You can specify a base directory for all
    installation directories as the value of \l{qbs::installPrefix}
    {qbs.installPrefix}.

    For example, the following properties specify where a set of QML files and
    an application executable are installed on Windows and Linux:

    \badcode
    Application {
        name: "myapp"
        Group {
            name: "Runtime resources"
            files: "*.qml"
            qbs.install: true
            qbs.installDir: condition: qbs.targetOS.contains("unix")
                ? "share/myapp" : "resources"
        }
        Group {
            name: "The App itself"
            fileTagsFilter: "application"
            qbs.install: true
            qbs.installDir: "bin"
        }
        qbs.installPrefix: condition: qbs.targetOS.contains("unix")
            ? "usr/local" : "MyApp"
    }
    \endcode

    On Windows, the QML files will ultimately get installed in
    \c{MyApp\resources} and the application executable in \c MyApp\bin,
    for instance under \c{C:\Program Files}. On Linux, the QML files will be
    installed in \c /usr/local/share/myapp and the executable in
    \c /usr/local/bin.

    By default, \l{qbs::installRoot}{qbs.installRoot} creates the
    \c install-root directory in the build directory for packaging the binaries
    before installation. It is a temporary directory that is usually not
    available when the application is run, and it should therefore not be set in
    the project files. You can override the default value from the command line,
    as described in \l{Installing Files}.

    \section2 Multiplexing Properties

    The following properties are specific to \l{Multiplexing}
    {product multiplexing}:

    \list
        \li \l{qbs::}{architectures}
        \li \l{qbs::}{buildVariants}
        \li \l{qbs::}{profiles}
    \endlist
*/

/*!
    \qmlproperty string qbs::configurationName
    \since Qbs 1.6
    \readonly

    The name of the current build configuration.

    The build configuration is set via the command line parameter \c
    config. For more information, see \l{build}{build}.

    \defaultvalue \c{"default"}
*/

/*!
    \qmlproperty string qbs::buildVariant

    The name of the build variant for the current build.

    Possible values are \c{"debug"}, \c{"release"} and \c{"profiling"}.
    A debug build usually contains additional debug symbols that are needed for
    debugging the application and has optimizations turned off. A profiling
    build usually contains debug symbols and has optimizations turned on. This
    is useful for profiling tools or when you need to retain debug symbols
    in a release build. A release build is a build without debug information and
    with optimizations enabled.

    \defaultvalue \c{"release"} if
    \l{qbs::configurationName}{qbs.configurationName} is \c{"release"}. Otherwise
    \c{"debug"}
*/

/*!
    \qmlproperty bool qbs::debugInformation

    Whether to generate debug information.

    \defaultvalue \c{true} if \l{qbs::buildVariant}{qbs.buildVariant} is \c{"debug"} or
    \c{"profiling"}. Otherwise \c{false}.
*/

/*!
    \qmlproperty bool qbs::enableDebugCode

    Whether to enable debug functionality in the product. Not to be confused
    with generation of debug symbols or the code optimization level.

    The property changes the following things when enabled:
    \list
         \li Passes a flag to the Windows linker to link against a debug
             Windows CRT (common runtime) library
             (for example /MTd instead of /MT)
    \endlist

    The property changes the following things when disabled:
    \list
         \li Passes the \c{NDEBUG} define to the compiler
    \endlist

    Typically, this property is enabled for debug builds and disabled for
    release or profiling builds.

    \defaultvalue \c{true} for debug builds, \c{false} otherwise.
*/

/*!
    \qmlproperty string qbs::optimization

    The general type of optimization that should be performed by all toolchains.

    Allowed values are:

    \list
        \li \c{"fast"}
        \li \c{"none"}
        \li \c{"small"}
    \endlist

    \defaultvalue \c{"none"} if \l{qbs::buildVariant}{qbs.buildVariant} is \c{"debug"}.
    Otherwise \c{"fast"}.
*/

/*!
    \qmlproperty string qbs::targetPlatform
    \since 1.11

    The OS you want to build the project for.

    This property is typically set in a profile or for a particular product
    where the target OS is always known (such as an Apple Watch app written in
    native code).

    For example, a profile used for building for the iOS Simulator platform will have this
    property set to the \c ios-simulator value:
    \code
        profiles.xcode-iphonesimulator.qbs.targetPlatform: "ios-simulator"
    \endcode

    You should generally treat this property as \e{write-only} and avoid using
    it to test for the current target OS. Instead, use the \l{qbs::}{targetOS}
    property for conditionals.

    \section2 Relation between targetPlatform and targetOS

    This table describes the possible values and matching between the \c targetPlatform

    \sa {Target Platforms}

*/

/*!
    \qmlproperty string qbs::architecture

    The target platform's processor architecture.

    \c{undefined} indicates that the target platform is architecture-independent
    (for example the CLR or JVM).

    This property is typically set in a profile.

    Commonly used values are: \c{"x86"}, \c{"x86_64"}, and \c{"arm"}.

/*!
    \qmlproperty stringList qbs::toolchain

    Contains the list of string values describing the toolchain and toolchain
    family that is used to build a project.

    This property is deduced from the \l{qbs::}{toolchainType} property and is typically
    used to test for a particular toolchain or toolchain family in conditionals:

    \code
        Properties {
            // flags for GCC
            condition: qbs.toolchain.contains("gcc")
            cpp.commonCompilerFlags: ...
        }
        Properties {
            // flags for MSVC
            condition: qbs.toolchain.contains("msvc")
            cpp.commonCompilerFlags: ...
        }
    \endcode

    Unlike \l{qbs::}{toolchainType}, which contains a single value, \c qbs.toolchain
    is a string list which also contains the toolchain family. This allows to make
    conditions and checks simpler. For example, instead of:

    \code
    (qbs.toolchainType === "xcode" || qbs.toolchainType === "clang" || qbs.toolchainType === "gcc")
    \endcode

    use:

    \code
    qbs.toolchain.contains("gcc")
    \endcode

    since XCode, GCC and Clang belong to the \c "gcc" family.

    \section2 Relation between toolchainType and toolchain

    This table describes the possible values and matching between the \l{qbs::}{toolchainType}

/*!
    \qmlproperty stringList qbs::targetOS
    \readonly

    Contains the list of string values describing the OS and OS family that is
    used to build a project.

    This property is calculated based on the \l{qbs::}{targetPlatform} property and is typically
    used to test for a particular OS or OS family in conditionals:
    \code
        Group {
            // Includes all Unix-like platforms, such as: Linux, BSD, Apple platforms and others.
            condition: qbs.targetOS.contains("unix")
            files: ...
        }
        Group {
            // Includes all Apple platforms, such as macOS, iOS, and iOS Simulator.
            condition: qbs.targetOS.contains("darwin")
            files: ...
        }
        Group {
            // Includes only macOS
            condition: qbs.targetOS.contains("macos")
            files: ...
        }
    \endcode
    Avoid using \l{qbs::}{targetPlatform} for this purpose. For example, instead of:

    \code
    qbs.targetPlatform === "macos" || qbs.targetPlatform === "ios" || qbs.targetPlatform === "tvos" || qbs.targetPlatform === "watchos"
    \endcode

    use

    \code
    qbs.targetOS.contains("darwin")

    \endcode

    However, in some cases using \l{qbs::}{targetPlatform} would be acceptable, such as
    when the resulting condition would be simpler while still being correct:

    \code
    qbs.targetPlatform === "linux"
    \endcode

    versus
    \code
    qbs.targetOS.contains("linux") && !qbs.targetOS.contains("android")
    \endcode

    For the complete list of possible values, see
    \l{Relation between targetPlatform and targetOS}.

    \since Qbs 1.4

    The global installation root. It is implicitly prepended to all values
    of \l{qbs::}{installPrefix} in the context of installation.

    \note This property is fundamentally different from \l{qbs::}{installDir}
    and \l{qbs::}{installPrefix} in that it must not be visible to the code
    being built. In fact, the install root is often just a temporary location
    used to package the binaries, which should therefore not assume they will be
    in that location at run-time. For the same reason, this property
    is usually not set from within project files.
