    \title Module qbs
    \since 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.

    \section1 General Properties

        \li 1.0
        \li \c{undefined}
        \li Specifies the target platform's processor architecture. \c{undefined} indicates that
            the target platform is architecture-independent (for example the CLR or JVM).
            This is typically set in a profile.
            Commonly used values are: \c{"x86"}, \c{"x86_64"} and \c{"arm"}.
    \row
        \li toolchain
        \li \c{stringList}
        \li 1.0
        \li \c{undefined}
        \li Specifies the attributes of the toolchain that is going to be used for this build.
            Typical values include: \c{"gcc"}, \c{"llvm"}, \c{"clang"}, \c{"mingw"}, \c{"msvc"}
    \row
        \li sysroot
        \li \c{string}
        \li 1.0
        \li \c{undefined}
        \li Specifies the sysroot of the target platform.
            This property is typically set in a profile for cross-compiling.
    \row
        \li pathListSeparator
        \li \c{string}
        \li 1.0
        \li \c{";"} on Windows,
            \c{":"} on Unix
        \li Holds the platform-specific separator for path list that is used in environment
            variables or other contexts.
    \row
        \li nullDevice
        \li \c{string}
        \li 1.4.2
        \li \c{"NUL"} on Windows,
            \c{"/dev/null"} on Unix
        \li Holds the platform-specific file path corresponding to the null device.
    \row
        \li shellPath
        \li \c{path}
        \li 1.5
        \li \c{"%COMSPEC%"} on Windows,
            \c{"/bin/sh"} on Unix
        \li Holds the platform-specific file path corresponding to the command line interpreter.
            On Windows this is the path to \c{cmd.exe}, which is held in the \c{COMSPEC}
            environment variable - typically \c{C:/Windows/System32/cmd.exe},
            and on Unix-like platforms this is \c{/bin/sh}.
    \endtable

    \section1 Environment Properties

    This section lists constant, read-only properties set by \QBS internally.
    These properties should not be overridden.

    \table
    \header
        \li Property
        \li Type
        \li Since
        \li Default
        \li Description
    \row
        \li hostOS
        \li \c{stringList} (read only)
        \li 1.0
        \li \c{undefined}
        \li This property is set by \QBS internally and specifies the OS \QBS is running on.
            The possible values for this property are the values of \c targetOS, though some may not
            be supported.
    \row
        \li hostOSVersion
        \li \c{string} (read only)
        \li 1.2
        \li \c{undefined}
        \li The host operating system version. Currently only defined for Windows and Apple
            platforms. Consists of two or three numbers separated by dots, for instance "10.9" or
            "6.3.9600".
    \row
        \li hostOSBuildVersion
        \li \c{string} (read only)
        \li 1.2
        \li \c{undefined}
        \li The host operating system's build version. Currently only defined for Windows and Apple
            platforms. On Windows, this is the 4 or 5 digit Windows build number and is equivalent
            to \c versionPatch. On Apple platforms, this is a standard build number in the Apple
            versioning scheme, for instance "13C64".
    \row
        \li hostOSVersionMajor
        \li \c{int} (read only)
        \li 1.2
        \li \c{hostOSVersionParts[0]}
        \li The host operating system major version.
    \row
        \li hostOSVersionMinor
        \li \c{int} (read only)
        \li 1.2
        \li \c{hostOSVersionParts[1]}
        \li The host operating system minor version.
    \row
        \li hostOSVersionParts
        \li \c{list} (read only)
        \li 1.2
        \li \c{empty}
        \li The host operating system version as a list.
            For instance, Windows 8.1 (version 6.3.9600) would correspond to a value of
            \c[6, 3, 9600].
    \row
        \li hostOSVersionPatch
        \li \c{int} (read only)
        \li 1.2
        \li \c{hostOSVersionParts[2]}
        \li The host operating system patch level.
    \row
        \li version
        \li \c{string} (read only)
        \li 1.4.1
        \li
        \li Version number of \QBS as a string, i.e. "1.4.1".
    \row
        \li versionMajor
        \li \c{int} (read only)
        \li 1.4.1
        \li
        \li Major version number of \QBS.
    \row
        \li versionMinor
        \li \c{int} (read only)
        \li 1.4.1
        \li
        \li Minor version number of \QBS.
    \row
        \li versionPatch
        \li \c{int} (read only)
        \li 1.4.1
        \li
        \li Patch version number of \QBS.
    \endtable

    \section1 Installation Properties

    This section lists properties specific to the \QBS installation mechanism.
    See \l{Installing Files} for more information.

    \table
    \header
        \li Property
        \li Type
        \li Since
        \li Default
        \li Description
    \row
        \li install
        \li \c{bool}
        \li 1.0
        \li \c{false}
        \li Specifies whether to install a certain set of files.
            This is typically set in a \c{Group} item to mark a number of files as installable.
            \note Artifacts for which this property is enabled automatically receive the file tag
            "installable". This is useful for writing packaging-related rules.
    \row
        \li installSourceBase
        \li \c{string}
        \li 1.4
        \li see below
        \li Specifies the base directory of the local files that are going to be installed. The
            source base directory is omitted from the target directory path specified in
            \c{installDir}. The default value of this property is the directory of the current file
            to be installed, relative to the product's source directory.
    \row
        \li installDir
        \li \c{string}
        \li 1.0
        \li \c{undefined}
        \li Specifies the installation directory for the files of a product or a \c{Group}. The
            value of this property is a path that is relative to \c installPrefix.
    \row
        \li installPrefix
        \li \c{string}
        \li 1.1
        \li \c{empty}
        \li Specifies the global installation prefix. It is implicitly prepended to all values of
            \c installDir. The \c installPrefix itself is relative to the \c installRoot in the
            context of installation.
    \row
        \li installRoot
        \li \c{string}
        \li 1.4
        \li \c{<build dir>/install-root}
        \li Specifies the global installation root. It is implicitly prepended to all values
            of \c installPrefix in the context of installation.
            \note This property is fundamentally different from \c installDir and \c 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.
