the long option name. This feature was added in order to resolve

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

name, and that if you want to set the NMAGIC flag you should use -N

196 |

|
or --omagic. */
