NetBSD/usr.sbin/user/userinfo.8
agc 7497747c60 Add new functionality, and fix some bugs and oversights:
+ Moved all internal definitions from usermgmt.h to user.c
+ Added prototypes to usermgmt.h
+ Allow defaults to be set at build time
+ Check the effective uid is 0 if any data is to be modified
+ Check all numeric uids and gids really are numeric
+ Fix a bug (reported by lenb at sasquatch.com) where new ranges were
appended to old ranges, rather than replacing them
+ Add userinfo(8) and groupinfo(8) utilities (if EXTENSIONS is
defined), whereby user and group information can be displayed.  Add
manual pages for new utilities.  Add front-end calling from user(8)
and group(8) accordingly.
+ Make all functions visible outside the user.c file again.  User and
group manipulation may be split out into a separate shared lib in the
future
+ Split off main function into a separate main.c
+ Changed default group to be "users"
+ Changed despatch table for commands to work in a more sane manner
+ Added "default-group" target to Makefile, so that the default group
can be made easily.
