--file did not make that many sense, it is easier to just pass the filename
as an argument
Call to parent constructor was misplaced, that made the script specific
options pretends they were generic maintenance parameters.
Wikitext can be given by stdin or using a file. The wikitext will be parsed
using 'CLIParser' as a title. This can be overriden with --title option.
Example1:
$ php parse.php --title foo
''[[foo]]''^D
<p><i><strong class="selflink">foo</strong></i>
</p>
Example2:
$ echo "'''bold'''" > /tmp/foo
$ php parse.php --file /tmp/foo
<p><b>bold</b>
</p>$
Example3:
$ cat /tmp/foo | php parse.php
<p><b>bold</b>
</p>$
