/*
 *  PROGRAM:        Firebird 2.0 control panel applet
 *  MODULE:         fbpanel.cpp
 *  DESCRIPTION:    The FBPanel unit does the following things:
 *                    - It manages the display of the icon in the 
 *                      Control Panel manager 
 *                    - It tests whether Firebird is installed 
 *                    - If Fb is installed it sets the status of items 
 *                      that can be read from the Firebird registry entries
 *                      and launches the Applet.
 *
 *                  Everything else is handled by the fbdialog unit. This is 
 *                  not a good thing as UI stuff is integrated with management 
 *                  and diagnostic stuff. A better design for Fb 2.0 would be 
 *                  to separate everything out and share the code with the 
 *                  existing command line tools that manage services and 
 *                  installation settings.
