That's a silly statement.  The rule is that the extensions
don't matter to the /kernel/ - and they don't - but they may 
matter to programs that are going to process a particular
file, and there are plenty of examples where they do.  Try 
using the C compiler to compile a source file you've chosen 
to name foo.q 

Nonetheless, this is a problem we need to solve cleanly,
and solving it just by suffixes is probably not sufficient,
although perhaps a useful hint to humans.

* How can an LSB RPM be distinguished from a non-LSB one?

* Can this be done without requiring existing tools to rev?
