  User Options
  Following defines and options can be changed by user.

(* File format support linking options.
  Define formats which you don't want to be registred automatically.
  Default: all formats are registered = no symbols defined.
  Example: If you want to disable JPEG support just uncomment //{$DEFINE DONT_LINK_JPEG} line
*)

                             // registered depends on settings in

  to be concerned with this - proper component library is selected automatically
  according to your compiler. }
