Okay, here's what I want to do:

As a user on a NetBSD box, I want to make 'man' look in "whatever the system
directories are", plus also "$HOME/man/manN".

How can I do this?  Basically, I want a way to set $MANPATH such that, if
nothing is found in the directories I specify, man falls back on 'man.conf' -
or I want a way to get the "correct" $MANPATH to append things to.
