192 
       the confusion about the -omagic command line switch.  Is it setting
193 
       the output file name to "magic" or is it setting the NMAGIC flag on
194 
       the output ?  It has been decided that it is setting the output file
195 
       name, and that if you want to set the NMAGIC flag you should use -N
