We're adding NeXT machines to a Sun NFS server. People on the Suns use  
FrameMaker. FrameMaker and Sun applications in general do not agree on any  
convention to use standard file extensions such as *.frame *.eps ....
Frame users on the Sun must have the freedom to name their documents without  
the .frame extension (I can't change that). 

Instead they use the so called /etc/magic file. A table that identifies files  
by it's contents in the head of the file e.g.

	0       string          %!              PostScript document
	0       string          \037\235        compressed data
	0       long            0100554         APL workspace (Ken's original?)

Sun has taken over this functionality from S5R3.1 1.25. NeXT only relies on the  
extensions which are classified only by existing (installed) applications. This  
does not work out in heterogeneous NFS environments as the one I described.

The worst case solution would be to create symbolic links that contains the  
correct NeXT specific extensions, but if you're using a document management  
software and over 100 documents are created during one day ...

Thanks for any comment ...
