No thanks.  I've been playing with 3.0-CURRENT on a 486 laptop,
and recall running "man ppp" took ages when it was creating a
catpage; "please wait..." didn't help.  But I also recall that
I knew that on a slow box things run slow, and I also recall
that not having catpages on that box gave me much better
interactive response times from man(1).
