+// This module handles dealing with user input & feedback\r

+// and Refresh Mgrs, Memory Mgr for background save/restore\r
+//\r
+// Globals:\r
+// ingame - Flag set by game indicating if a game is in progress\r
+// abortgame - Flag set if the current game should be aborted (if a load\r
+// game fails)\r
+// loadedgame - Flag set if a game was loaded\r
+// abortprogram - Normally nil, this points to a terminal error message\r
+// if the program needs to abort\r
+// restartgame - Normally set to gd_Continue, this is set to one of the\r
+// difficulty levels if a new game should be started\r
+// PrintX, PrintY - Where the User Mgr will print (global coords)\r
+// WindowX,WindowY,WindowW,WindowH - The dimensions of the current\r
+// window\r
