fonts.dir and fonts.scale

Hi, 

I have an old IBM fonts package used internally only and I'm willing to 
repackage it with
the latest Fedora's Font Policy to use it on Fedora 12.

I have read the policies pages and I am a bit confused with the lot of 
information there.

I split the package in 3 new ones (simple) for each font family and gave 
the proper names. My
doubt is: the old package creates the files fonts.dir and fonts.scale 
during package installation
(%post) using  'ttmkfdir' and 'mkfontdir' . Can someone tell me if this 
files are still necessary in
Fedora12 or 11 ? Should I create them ?
I see that some F11 packages have this files, but others do not.

I appreciate any help.
