Applet to put Applet in a Frame...

Here's an applet that will run a specified applet in an external frame.
Put this (or a link to it) at the same base url as your applet.
Change your <applet> tag to specify FrameApplet rather than the one you
want to display. Then add one extra <param> named "applet" with a value
of the name of the applet to run.
It should display the named applet in an external fram and change itself
into a "kill blah" button. Of course, Netscape doesn't support sizing
properly yet. However, the things I've tried work under b3.
Comments? (am I doing anything bogus in here?)
Obvious improvements:
Find a way around the location problem
Add separate width & height to avoid a resize.
