Only the hun_extra.php file needs a little explanation.
This file contains the translation for some plugins.
Every plugin has a part in the file, starting with /* part name */ (common php remark block)
The parts (plugins)
- Poll (1.3): Just copy this part to the hun.php and forget about the hack_poll_txt.php
- Smilies (2.0): Put this block to the hun.php and remove this (these) line(s) from the hack_smilies2.php
- Who's online (2.0 rev.2): Put this block to the hun.php and remove these lines from the whoisonline.php

Hope this is clear, if not, don't hesitate to write me an email:
