Installation: 

1. Backup original install.php
2. Copy install.php file into PunBB root directory
3. Copy language file into PunBB language directory \lang\English (same as other language file)

And now PunBB have multilanguage support in Installation, the language you choose 
and after PunBB installation the forum default language will be set.

I hope this mod would help PunBB installation become more friendly with those people that 
does not familiar in English.
