   2 /**
   3  * CLI script to easily parse some wikitext.
   4  * Wikitext can be given by stdin or using a file. The wikitext will be parsed
   5  * using 'CLIParser' as a title. This can be overriden with --title option.
   6  *
   7  * Example1:
   8  * @code
   9  * $ php parse.php --title foo
  10  * ''[[foo]]''^D
  11  * <p><i><strong class="selflink">foo</strong></i>
  12  * </p>
  13  * @endcode
  14  *
  15  * Example2:
  16  * @code
  17  * $ echo "'''bold'''" > /tmp/foo
  18  * $ php parse.php --file /tmp/foo
  19  * <p><b>bold</b>
  20  * </p>$
  21  * @endcode
  22  *
  23  * Example3:
  24  * @code
  25  * $ cat /tmp/foo | php parse.php
  26  * <p><b>bold</b>
  27  * </p>$
  28  * @endcode
