   6  * Parse some wikitext.
   7  *
   8  * Wikitext can be given by stdin or using a file. The wikitext will be parsed
   9  * using 'CLIParser' as a title. This can be overridden with --title option.
  10  *
  11  * Example1:
  12  * @code
  13  * $ php parse.php --title foo
  14  * ''[[foo]]''^D
  15  * <p><i><strong class="selflink">foo</strong></i>
  16  * </p>
  17  * @endcode
  18  *
  19  * Example2:
  20  * @code
  21  * $ echo "'''bold'''" > /tmp/foo.txt
  22  * $ php parse.php /tmp/foo.txt
  23  * <p><b>bold</b>
  24  * </p>$
  25  * @endcode
  26  *
  27  * Example3:
  28  * @code
  29  * $ cat /tmp/foo | php parse.php
  30  * <p><b>bold</b>
  31  * </p>$
  32  * @endcode
