   3  * Parse some wikitext.
   4  *
   5  * Wikitext can be given by stdin or using a file. The wikitext will be parsed
   6  * using 'CLIParser' as a title. This can be overriden with --title option.
   7  *
   8  * Example1:
   9  * @code
  10  * $ php parse.php --title foo
  11  * ''[[foo]]''^D
  12  * <p><i><strong class="selflink">foo</strong></i>
  13  * </p>
  14  * @endcode
  15  *
  16  * Example2:
  17  * @code
  18  * $ echo "'''bold'''" > /tmp/foo.txt
  19  * $ php parse.php /tmp/foo.txt
  20  * <p><b>bold</b>
  21  * </p>$
  22  * @endcode
  23  *
  24  * Example3:
  25  * @code
  26  * $ cat /tmp/foo | php parse.php
  27  * <p><b>bold</b>
  28  * </p>$
  29  * @endcode
