/**
 * Another GeSHi example script
 *
 * Configure your Apache server with 'AcceptPathInfo true' and something like
 * 'Alias /viewmysource /var/www/geshi/contrib/aliased.php'. Don't forget
 * to protect this alias as necessary.
 *
 * Usage - visit /viewmysource/file.name.ext to see that file with syntax
 * highlighting, where "viewmysource" is the name of the alias you set up.
 * You can use this without an alias too, just by visiting
 * aliased.php/file.name.ext.
