+/**************************************************************
+ *
+ * Startup program for Darwin X servers
+ *
+ * This program selects the appropriate X server to launch:
+ *  XDarwin         IOKit X server (default)
+ *  XDarwinQuartz   A soft link to the Quartz X server
+ *                  executable (-quartz etc. option)
+ *
+ * If told to idle, the program will simply pause and not
+ * launch any X server. This is to support startx being
+ * run by XDarwin.app.
