%% Source code listings
%% takata.yoshiaki@kochi-tech.ac.jp, Mar. 2014.

%% This LaTeX code puts source code listings to landscape papers,
%% using listings.sty.
%% Use the following command for producing landscape pages:
%% $ dvipdfmx -l list.dvi
%%
%% The manual of listings.sty can be found in the follwing URL.
%% http://www.ctan.org/tex-archive/macros/latex/contrib/listings/listings.pdf
%% (Note that I'm not sure whether or not the listings.sty supports
%% source codes with Japanese characters.)
