Mime-types, shared-mime-info patch for squeak files?

"shared-mime-info" is a database for detecting file types, used by  
many modern Linux systems:

        http://freedesktop.org/wiki/Software/shared-mime-info

It's also used on the OLPC, and I need a patch for that database that  
at least recognizes etoys projects (which are zip files with a .pr  
file extension). But when we're at it, we could as well add  
recognition of image, changes, sources, changesets, mcz, sar, etc.

We need mime-types for these as well. The browser plugin uses

        application/x-squeak-project (*.pr)
        application/x-squeak-object  (*.sqo)
        application/x-squeak-source  (*.sts)

Maybe there are some more mime-types in use?

So - does anybody have this in shared-mime-info format, or would be  
willing to prepare soonish? It will go into OLPC as a patch first,  
but then to the official database, too.

Thanks,
