What I wanted to say was really "ALL programs in the world should support
a simple and easy way to query their version".

The actual implementation is not that important.

I especially like ways when you don't even need to run the program.
That way it also works for non-executable files !

root # what /bin/ls
/bin/ls:
         $Revision: 82.2.1.2 $
         PATCH_11_00: ls.o 99/09/29
root # what /lib/libc.a
/lib/libc.a:
         $ PATCH/11.00:PHCO_22076  Aug 16 2000 16:51:32 $
