 * Finger prints out information about users.  It is not portable since
 * certain fields (e.g. the full user name, office, and phone numbers) are
 * extracted from the gecos field of the passwd file which other UNIXes
 * may not have or may use for other things.
 *
 * There are currently two output formats; the short format is one line
 * per user and displays login name, tty, login time, real name, idle time,
 * and either remote host information (default) or office location/phone
 * number, depending on if -h or -o is used respectively.
 * The long format gives the same information (in a more legible format) as
 * well as home directory, shell, mail info, and .plan/.project files.
