/**
 * Parse some wikitext.
 *
 * Wikitext can be given by stdin or using a file. The wikitext will be parsed
 * using 'CLIParser' as a title. This can be overridden with --title option.
 *
 * Example1:
 * @code
 * $ php parse.php --title foo
 * ''[[foo]]''^D
 * <p><i><strong class="selflink">foo</strong></i>
 * </p>
 * @endcode
 *
 * Example2:
 * @code
 * $ echo "'''bold'''" > /tmp/foo.txt
 * $ php parse.php /tmp/foo.txt
 * <p><b>bold</b>
 * </p>$
 * @endcode
 *
 * Example3:
 * @code
 * $ cat /tmp/foo | php parse.php
 * <p><b>bold</b>
 * </p>$
 * @endcode
