//
//    Simple Atom Ext.r
//
//        This installer script source demonstrates how to define and
//        use an Atom Extender.  An Atom Extender is used to enhance or
//        replace the default copy mechanism of the Installer.  A good
//        example of the use of Atom Extenders is the InstaCompOne atom
//        extender that provides transparent decompression of files
//        during install.  Atom extenders can be referenced from file,
//        font, and resource atoms.
//
//    What this example does :
//        This example defines a simple atom extender which merely mimicks
//        the direct copy mechaism in the Installer.  Our simple atom
//        extender is then referenced from both a file and resource atom.
//
//        Two Custom Install options are provided to the user:
//
//        1) Installs a Example File onto the selected target
//        volume, using our Simple Atom Extender, which simulates the
//        default copy mechanism of the Installer.
//
//        2) Installs the 'PICT' 1000 resource item from within our Read
//        me file, again, using our Simple Atom Extender.
//
//     NOTE: When the Atom Extender resource ID entered in an atom is non-zero,
//        such as with this example script, ScriptCheck will look for an
//        accompanying ScriptCheck Extension file.  The assumption is that if
//        you are using an Atom Extender, your source files will not be in a
//        format that ScriptCheck can read and get information about.
//
//        The InstaCompOne atom extender is a good example of this.  In
//        the examples that use the InstaCompOne Atom Extender, the ScriptCheck
//        extension provided with InstaCompOne ("InstaCompOneSCExt.rsrc"
//        renamed to "<scriptname>.scx") is used.
//
//        With this Simple Atom Extender example, we also demonstrate how to define
//        and use your own script check extensions for use with your Atom Extenders.
//        See the source file "DirectCopySCExt.r" for further details.
