Just to elaborate on the documentation for the user...

Something which i would want to know how to do as a new admin or owner
of an selinux system is lock down a userid to something other than
unconfined_t. I.e. one userid to play games, one to do banking, etc.
This should be pretty simple, maybe

	useradd xa
	semanage user -a -R user_r xa
	semanage login -a -s xa xa

but figuring out the right recipes can be unnecessarily painful.

A few specific things which I think could help users (at least
those who don't use the guis):

1. 'semanage login help' (for instance) could give context-specific help

2. man adduser/useradd could point either to semanage, or to selinux.8
(and smack.8 if these are part of the man-pages project).

3. selinux.8 could use either a section on user/domain lockdown, or
a pointer to semanage, or a pointer to a seuser.8 or somesuch overview
file.
