    //  This is the directory structure on the local filesystem
    //  from which we'll create .zip archives:
    //  The root directory is /temp/filesToZip
    //  
    //  We have these files:
    //  /temp/filesToZip/faxCover.doc
    //  /temp/filesToZip/exe/Setup.exe
    //  /temp/filesToZip/images/cheese.jpg
    //  /temp/filesToZip/images/dude.gif
    //  /temp/filesToZip/images/img3.gif
    //  /temp/filesToZip/images/img4.gif
    //  /temp/filesToZip/images/img5.gif

    //  /temp/filesToZip/images/imageInfo/scream.xml

    //  There are three properties to help control the paths stored
    //  within a .zip:

    //  AppendFilesEx, the AppendFromDir sets the base of the 
    //  directory tree appended (if the file pattern contains a 
    //  relative path, or no path at all).
