172 the long option name. This feature was added in order to resolve
173 the confusion about the -omagic command line switch. Is it setting
174 the output file name to "magic" or is it setting the NMAGIC flag on
175 the output ? It has been decided that it is setting the output file
176 name, and that if you want to set the NMAGIC flag you should use -N
