/etc/pwcntl on the 3B1 (3.51), anyone?

[Dave Ihnat]

Before I waste my time re-inventing the wheel, I guess I'll ask here.  There's
a file in /etc called 'pwcntl'; it's certainly referenced by /bin/login, and in
/usr/bin/Ulogin.  A casual dump indicates it may be the 3B1 version of a
lastlog analog, but I've not found any documentation on it, nor does it
appear to be referenced anywhere in /usr/include or /usr/include/sys.

Has someone else taken this file apart?  If not, it shouldn't be too
outrageous, but I'd prefer not to duplicate effort. 

	Thanks,
