5.4 Command line switches

     /C              Compile the nodelist if it (or FDNODE.CTL) has
                     been updated since the last time it was compiled,
                     otherwise exit directly. This is useful for
                     compiling the nodelist in batch files since it
                     avoids the "Nodelist files are up-to-date,
                     compile anyway?" prompt.

     /F              Forces FDNC to compile the nodelist regardless of
                     whether or not it has been updated.
