 * I use this plugin on my blog and I like it. Recently I improved it by adding 
   new parameter “include” to the
 * `<pre>` tag. It allows you to include code from filesystem and highlight it as
   well. It is very handy when you have working example on the site and want to 
   show the source code on the blog.
 * patch is below
 *     ```
       $ diff wp-syntax.php.orig wp-syntax.php

       <     $ext = 'pre[id|name|class|style|lang|line|escaped|hightlight|src]';

       >     $ext = 'pre[id|name|class|style|lang|line|escaped|hightlight|src|include]';
       169c169,178
       <     $code = wp_syntax_code_trim($match[6]);
       ---
       >     $include_file = wp_syntax_code_trim($match[6]);
       >     $code = wp_syntax_code_trim($match[7]);
       >
       >     if (!empty($include_file)) {
       >       if (substr($include_file,0,4) == 'http')
       >               $code = file_get_contents($include_file);
       >       elseif (file_exists(ABSPATH.$include_file))
       >               $code = file_get_contents(ABSPATH.$include_file);
       >     }
