+% NOTE ON INTENTIONAL OMISSIONS: This reference card includes most GDB
+% commands, but due to space constraints there are some things I chose
+% to omit. In general, not all synonyms for commands are covered.
+% The GDB-under-Emacs section omits gdb-mode functions without default
+% keybindings. GDB startup options are not described.
