I have tried installing this but it does not appear on the modules page.

I installed to
/modules/wraps/

(Installing to modules/html/modules/wraps gives an error on the modules page.)

/xoops_trust_path/modules/
/xoops_trust_path/wraps/
/xoops_trust_path/wraps/whip_cream

I am unclear about step 2.
(2) name the directory name as you like. (eg. mycompany)
What directory and where do I put it?

Thanks
Frank
