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