structure of apple help

Question

I have inherited a mac app that needs some fixing and I have trouble with help on Snow Leopard.

Today the help is structured as: App/Contents/Resources/LANG.lproj/Help

I have trouble when trying to load non-English help pages, it always loads the English version on Snow Leopard.

I believe Mac OS thinks there are two help books in the app, not one with two localizations.

Some google gave: Apple Ref

There they structure help as App.help/Contents/Resources/LANG.lproj where App.help is placed in the Resources folder of the app.

My questions are basically:

1. Do I need to create the help as a bundle, or is a directory in the app ok?
2. Is the structure from the link the one to use?

I need the solution to work on both 10.5 and 10.6
