// --- Description:
// This the primary web site entrance control program.
// Its purpose is to test the client system and configuration to make certain the 
// client machine and browser will correctly render the web site content and be able
// to control navigation.  If so, then the program opens a new browser window that
// actually contains the web site content and navigational controls.

// --- Dependencies:
// This program requires that the following program files be preloaded before execution:
//     > BrowserDetectLite.js
//     > getipaddress.cgi (server-side script)
