+% 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".

% The GDB-under-Emacs section omits gdb-mode functions without default
