// -------------------------------------------------------------------------------------
// Modified	06.15.2000 for Intel by Brian Gregory
// Reason:	To abstract menu list generation from this file into an easier to manage
//          external file, to be included separately.
//          Also, to reformat. A couple extra bytes sent down the wire aint gonna
//          kill us.. and readability is a bear with 256+ column lines.
//          Also, to abstract the <many> image http references and put them in one
//          spot... 
//          ... Obfuscated code.. NO MORE!
//
//          MAJOR NEW STUFF:
//          You must include your own images from an external definitions file.
