//
//        Includes : system version screening, as well as customized user interface
//        and installation contents, based on existing system version of selected
//        target volume.
//
//        This example will install a Desk Accessory with the method proper to
//        the existing system folder on the selected target volume. Installation
//        of a Desk Accessory was chosen for this example because this is one of
//        the many cases where you may need to provide different installations
//        based upon which version of the operating system the user has.
//
//        Your needs may differ from this example. Many developers produce
//        applications that are dependent on System 7, and will not run under
//        System 6. In those cases, simply add a package containing your software
//        if the proper system version is found on the selected target volume.
//
//        If a proper system version cannot be found on the target volume
//        you may add the rule clause ReportVolError to dim or disable the Install
//        button in the dialog to prevent the user from installing software
//        that is inappropriate for the selected volume.
//
//        In this example we have arbitrarily chosen System 6.0 as the minimum
//        system required for installation. Your Desk Accessory may have different
//        requirements.
//
//        You may wish to allow the user to install software that falls outside
//        of the recommended installation. Use Custom Install for these cases.
//
//        This example checks for system version by checking the file version
//        of the System file on the selected target volume. This is not necessarily
//        the version of the currently running operating system. Users may have
//        different versions of system folders on different hard disks. The system
//        version that will be checked is that of the blessed system folder
//        on the currently selected target volume.
//
//        The CheckFileVersion call will look for an active system folder on
//        the selected target volume when checking the version of the System
//        file. The target spec used in the CheckFileVersion call uses the path
//        "special-macs:" which will look for an existing blessed system folder.
//        Once the blessed system folder has been found, target spec will 'point'
//        to the System file within the blessed system folder. If no blessed system
//        folder is found, path "special-macs:" will default to ":System Folder:".
//        In the case where the user has removed the Finder file from folder named
//        "System Folder" that still contains a copy of the System file, this check
//        for an existing system version on the target volume may be erroneous.
//
//
//        IMPORTANT: As of Installer version 4.0.3, the ReportVolError and
//        ReportSysError rule clauses do not function correctly when used
//        within the Global framework. Both rule clauses should disable the
//        Install button, and ReportSysError should disable the Switch Disk
//        button. Currently, when either of these rule clauses is evoked from
//        within the Global framework neither the Install or Switch Disk buttons
//        are disabled. Both rule clauses do work correctly within the Easy and
//        Custom frameworks. As a result, it is recommended that Report Error
//        clauses be implemented within Easy and Custom frameworks exclusively.

// • package comments

//     NOTE: The values that are assigned to the Custom Package Information
//    resource fields do not actually have any affect on the installation and
//    are ignored during installation. They can however assist the user in
//    choosing which packages they would like to include in their Custom
//    Installation or Custom Removal.

//     The following included file contains the icons for the two package comments.
//     I created the file with the icon resources ( 'ICN#', 'icl4' and 'icl8' )
//     by opening the application to be installed within ResEdit. I then copied
//    the 'ICN#', 'icl4' and 'icl8' icon resources into a new ResEdit file called
//    "Icons.rsrc" and assigned the resource items an ID of 9128, since their
//    original resource ID's had a value that was illegal for use with 'inpc'
//    resources ( they must be over 1024 ).
//
//     - An alternative to this method is to derez the application and to paste
//    the resulting resource definitions into this script file and to let the Rez
//    command build the icons every time that the installer script is Rezzed.
//    If you happen to forget to include the resources for the icons, ScriptCheck
//    will complain, but you will still be able to use the Rezzed installer script
//    to successfully perform an installation.
