-@ignore
 The GDB 4 release includes an already-formatted reference card, ready
 for printing on a PostScript or GhostScript printer, in the @file{gdb}
 subdirectory of the main source directory---in
 @file{gdb-4.2/gdb/refcard.ps} of the version 4.2 release.  If you have
 a PostScript or GhostScript printer, you can print the reference card
 by just sending @file{refcard.ps} to the printer.
