40 % Modifications made in order to handle different papersizes correctly.
41 % You only have to set the total width and height of the paper, the
42 % horizontal and vertical margin space measured from *paper edge*
43 % and the interline and interspec spacing.
44 % In order to support a new papersize, you have to fiddle with the
45 % latter four dimensions. Just try out a few values.
46 % All other values will be computed at process time so it should be
47 % quite easy to support different paper sizes - only four values to
50 % To find the configuration places, just search for the string
53 % Andreas Vogel (av@ssw.de)
57 % Uncomment the following `magnification' command if you want to print
58 % out in a larger font. Caution! You may need larger paper. You had
59 % best avoid using 3-column output if you try this. See the ``Three
60 % column format'' section below if you want to print in three column
63 %\magnification=\magstep 1
65 % NOTE ON INTENTIONAL OMISSIONS: This reference card includes most GDB
66 % commands, but due to space constraints there are some things I chose
67 % to omit. In general, not all synonyms for commands are covered, nor
68 % all variations of a command.
69 % The GDB-under-Emacs section omits gdb-mode functions without default
70 % keybindings. GDB startup options are not described.
71 % set print sevenbit-strings, set symbol-reloading omitted.
72 % printsyms, printpsyms, omitted since they're for GDB maintenance primarily
73 % share omitted due to obsolescence
74 % set check range/type omitted at least til code is in GDB.
