-The command-line keywords mimic the additional parameters that may
-appear in HTML syntax when the p3d file appears on a web page.  These
-are passed as given to the app, which may decide what to do with them.
+The command-line arguments following the application name are passed

 See pack3d.py for a script that generates these p3d files.
