hey guys,
I'm exploring OpenBSD and I often use it without internet connection so
I explore it via man pages mostly.

I found out about proot.1 and dpb.1 but I couldn't run them and couldn't
find them on my machine. I went through mail archives and found this [1]
thread about moving some of the ports manpages into the base system.
In that conversation Ingo Schwarze suggested a nice disclaimer that I
believe could've helped me to figure out that these tools are in ports
tree somewhere.

Below is a patch that basically does what Ingo suggested, except I chose
CAVEATS section for this instead of the suggested SEE ALSO.
Let me know what do you think (and let me know if I attached the diff wrong).
