A README file is required for CPAN modules since CPAN extracts the README file from a module distribution so that people browsing the archive can use it get an idea of the modules uses. It is usually a good idea to provide version information here so that people can decide whether fixes for the module are worth downloading. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES Perl 5.8.1 or later. COPYRIGHT AND LICENCE Copyright (C) 2010 by Fuji, Goro gfx.
