migrating from linux: missing commands: full syslogd, killall, man cache, setterm

[Franklin DeMatto <franklin_dematto_(_at_)_yahoo_(_dot_)_com>]

Please cc me all responses.

Does anyone know how to get the following features
(that us Linux users have come to rely on) in
OpenBSD?

1) Full syslogd .  Is it possible to have syslogd mail
certain messages, or send them to a named pipe, or
send them to a particular tty?

2) killall - kills processes by regex , not pid

3) man cache - it doesn't look like openbsd caches man
pages

4) setterm - useful

BTW, is there a command to add a user to a group (not
to make a new group, or change the user's groups, just
to add him to one)?
