Description:  Rwho with a users(1)-style output

Print a users(1)-style list of names for each host in the rwho spool directory
 
Before running make, choose the proper CAPLIB (ie. -ltermlib or -ltermcap).

Since rwho is pretty much a BSD animal (I think), the code has only been
tested on a vax (BSD 4.2), on a Sun 4 and on Sun 3s (SunOS 3.5 & 4.0)

Possible ru options:
    -a  print all names regardless of idle time (not unlike "rwho -a").
    -c  for repeated names, print the total number of repeats.
    -d  like -s but list hosts alphabetically, regardless of their subdomains.
    -m  don't drop repeated names.
    -r  mimic rwho(1) output.
    -s  print lists by host instead of by subdomain.
    -u  list uptimes like ruptime(1).
    -w  start a fresh line before the output can wrap around.
    -h  restrict output to those hosts given on the command line.
    -l  restrict output to those systems hosting the given users.
    -D  restrict output to those hosts within the given subdomain.
