    \property SystemInfo::currentCpuArchitecture

    The architecture of the CPU that the application is running on, in text format.

    Possible values include:
    \list
        \li "i386"
        \li "x86_64"
    \endlist

    \note This function depends on what the OS will report and may not detect the actual CPU
    architecture if the OS hides that information or is unable to provide it. For example, a 32-bit
    OS running on a 64-bit CPU is usually unable to determine whether the CPU is actually capable
    of running 64-bit programs.

    \sa QSysInfo::currentCpuArchitecture()

    \property SystemInfo::kernelType

    The type of the operating system kernel the installer was compiled for. It is also the
    kernel the installer is running on, unless the host operating system is running a form of
    compatibility or virtualization layer.

    For Windows, Linux, and macOS this will return:
    \list
        \li "winnt"
        \li "linux"
        \li "darwin"
    \endlist

    On Unix systems, it returns the same as the output of \c {uname -s} (lowercased).

    \sa QSysInfo::kernelType()
*/
QString SystemInfo::kernelType() const

    return QSysInfo::kernelType();
}

/*!
    \property SystemInfo::kernelVersion

    The release version of the operating system kernel. On Windows, it returns the version of the
    NT or CE kernel. On Unix systems, including macOS, it returns the same as the \c {uname -r}
    command would return.

    Example values are:

    \list
        \li "6.1.7601" for Windows 7 with Service Pack 1
        \li "3.16.6-2-desktop" for openSUSE 13.2 kernel 3.16.6-2

/*!
    \property SystemInfo::productType

    The product name of the operating system this application is running in.

    Example values are:

    \list
        \li "windows"
        \li "opensuse" (for the Linux openSUSE distribution)
        \li "osx"

/*!
    \property SystemInfo::productVersion

    The product version of the operating system in string form. If the version could not be
    determined, this function returns "unknown".

    Example values are:

    \list
        \li "7" for Windows 7
        \li "13.2" for openSUSE 13.2
        \li "10.8" for OS X Mountain Lion

    \property SystemInfo::prettyProductName

    A prettier form of SystemInfo::productType and SystemInfo::productVersion, containing other
    tokens like the operating system type, codenames and other information. The result of this
    function is suitable for displaying to the user.

    Example values are:

    \list
        \li "Windows 7"
        \li "openSUSE 13.2 (Harlequin) (x86_64)"
