Obtained from: The NYS project

This program is used for both generating and dumping NIS maps. It's very
similar to the 'makedbm' command in SunOS. This program was ported from
the yps-0.21 package. It's close to the original except for the GDBM to
DB conversions. This was simple compared to the other YP components.
