*  Intialize the zip object by calling NewZip.
loZip.NewZip("myZip.zip")

*  Add a reference to a file on disk to the zip object.
*  (When appending files to a zip, the files are not actually
*  read into memory.  References to the file(s) are added.
*  When WriteZip is called, the referenced files are streamed in
*  and compressed to the .zip.)

lnSaveExtraPath = 0
lnSuccess = loZip.AppendOneFileOrDir("c:/temp/a/hamlet.xml",lnSaveExtraPath)

*  The zip object references a single file.
*  Retrieve the entry object...

loEntry = loZip.GetEntryByIndex(0)

*  Set the entry's filename to anything you want:
loEntry.FileName = "somethingElse.xml"

*  Note: Internally, the zip component retains the name of
*  the file referenced.  The current setting of the zip entry's
*  FileName property is stored in the .zip when writing.

*  The zip written here will contain somethingElse.xml
lnSuccess = loZip.WriteZipAndClose()
