%   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
% out in a larger font.  Caution!  You may need larger paper.  You had
% best avoid using 3-column output if you try this.  See the ``Three
% column format'' section below if you want to print in three column
% format.

%\magnification=\magstep 1
%
% 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, set symbol-reloading 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.
