#  Append a directory tree.  The AppendFiles does
#  not read the file contents or append them to the zip
#  object in memory.  It simply appends references
#  to the files so that when WriteZip (or WriteZipAndClose,
#  or WriteExe, etc.) is called, the files are compressed
#  and encrypted.

entry = zip.GetEntryByName("Setup.exe")
if (entry == nil )
    print "Failed to find entry in .zip" + "\n"
    exit
end

#  Change the filename of this entry.
#  When the .zip is written, the "Setup.exe" is streamed
#  in from the filesystem and compressed into the .zip,
#  and named as "install.exe"
entry.put_FileName("install.exe")
