//*** Sample AppletHost to test class loading
//*** README: Here's a sample invocation that'll work if
//            you're connected:
//
// java AppletHost http://condor.depaul.edu/dmumaugh/JDP/test/misc.class \
//    misc
//
// The 1st command-line argument is the full URL, which includes the applet file
// misc.class.
//
// The 2nd command-line argument is the name of the applet, misc. I should do
// more work and extract the name from the URL (next release).
// Below is the RemoteClassLoader that you'll need.
