This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been

I couldn't make any sense of the sentence "Eval variables in this file." so I
left it alone.
also allow creation of new local group when NIS groups are used.
this can probably be done more elegantly, and needs more thought.
o less restrictive, you can choise uid, gid ...
o invite user into some groups
o encrypted passwords with crypt
o batch mode (for instance, this works now:
$ adduser -batch jkh guest,uuadmin "Jordan K. Hubbard" passwd
see manpage for more details)
