- % Modifications made in order to handle different papersizes correctly.
- % You only have to set the total width and height of the paper, the
- % horizontal and vertical margin space measured from *paper edge*
- % and the interline and interspec spacing.
- % In order to support a new papersize, you have to fiddle with the
- % latter four dimensions. Just try out a few values.
- % All other values will be computed at process time so it should be
- % quite easy to support different paper sizes - only four values to
- % guess :-)
- %
- % To find the configuration places, just search for the string
- % "CONFIGURATION".

- % Uncomment the following `magnification' command if you want to print

- % 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, nor
- % all variations of a command.
- % The GDB-under-Emacs section omits gdb-mode functions without default
- % keybindings. GDB startup options are not described.
- % set print sevenbit-strings omitted.
- % printsyms, printpsyms, omitted since they're for GDB maintenance primarily
- % share omitted due to obsolescence
- % set check range/type omitted at least til code is in GDB.
