    // 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/scream.jpg
    // /temp/filesToZip/images/imageInfo/scream.xml
    // /temp/filesToZip/images/imageInfo/cheese.xml
    // /temp/filesToZip/text/html/bonaireFishing.html
    // /temp/filesToZip/text/html/upload.html
    // /temp/filesToZip/text/txt/hello.txt

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

    // First we'll demonstrate AppendFromDir
    // When a directory tree is appended via AppendFiles or
    // AppendFilesEx, the AppendFromDir sets the base of the 
    // directory tree appended (if the file pattern contains a 
    // relative path, or no path at all).

    // Clear the zip object.

    // images/imageInfo/cheese.xml
    // text/xml/hamlet.xml
    // text/xml/pigs.xml

    // The PathPrefix property adds an arbitrary path prefix to each
    // file in the .zip.
    // For example:

    // in the zip:
    // For example:

    // Clear the zip object.
