ozpost shipping module

[remoteone]

I created an empty ozpost.php file in /includes/languages/english/modules/shipping/ (the / vs \ path symbolism is simply a case of me pasting the text as is)

The first errors have gone but still getting this error:
in admin> modules >shipping

These last lines are repeated many times.

Thats a serious beard you've got going there by the way !
