[Lenny Tropiano]

Yes, I whipped this up quick... It does what it supposed to, and no more.
Nothing fancy ... :-)

X * look_pwcntl.c
X *
X * Program to dump out entries of /etc/pwcntl, that is created by the 
X * stock login(1M) program on the UNIX PC computer.  This will print out
X * all the entries, and their last login time.  It also compares login
X * names with the /etc/passwd to check for validity.  The login will
X * record all entries, correct or not.  
X * 
X * ** NOTE ** This is a quick and dirty program, very simple, but someone
X *            had to do it! :-)
