161 This is an overloading of the use of this enum, since originally it
162 was only intended to tell the --help display function how to display
163 the long option name. This feature was added in order to resolve
164 the confusion about the -omagic command line switch. Is it setting
165 the output file name to "magic" or is it setting the NMAGIC flag on
166 the output ? It has been decided that it is setting the output file
167 name, and that if you want to set the NMAGIC flag you should use -N
170 /* Don't mention this option in --help output. */
