 % In order to make sure that the input/output header follows the code it 
 % preceeds, we have to use a minipage environment.  This causes problems
 % for large blocks of input and output.  If there is a large input/output
 % block, we don't want to minipage the whole thing since it will break
 % the line wrapping.  The solution is to split the input/output line by
 % line before we minipage which allows us to minipage the first X lines
 % preceeding the input/output bar.  That way, a select amount of lines
 % force the input/output bar to follow it around.
 ((*- set min_header_lines = 3 -*))
 
 % This is the number of characters that are permitted per line.  It's
 % important that this limit is set so characters do not run off the
 % edges of latex pages (since latex does not always seem smart enough
 % to prevent this.)
