Agreed, but there are times when you don't want your stuff to go in the
same place as a distributions stuff, if only to keep a serperate "namespace"
for your applications.

Sure, and that is why I was suggesting some sort of distribution tool
to help handle this. In this way the packager does not right his or her
own possbibly buggy tool handle this, but the maintner of the distribution
provides a utility that handles this bug free (OK I'm dreaming).

I would prefere this too, but after re-reading the gnu man.config and man
man pages, and the comments in /etc/man.config, I am positive that the
behaviour you get from the man is if the MANPATH is set (which you would do
in a /etc/profile.d script) it will ignore man.config. I do not want
/etc/man.config ignored. I want to inherit the good work at RedHat, not
go on my own. If on the other hand one in their RPM (because profile.d
will not get you there) edits the /etc/man.config file you run into the
same issues you mentioned with programs on HP that each on their own
(rather than through a distribution supplied program) edit the MANPATH
file.

Nice code, but it assumes that you know what should be on the system before
you alter things (at least thast was my cursory reading). At best you could
get it tuned to a particular release of a distribution, but as soon as the
maintaineers of the distribution alter man.config or the sysadmin does
all bets are off.

Again, I agree its nice code (OK its very clean wonderful code (-:) but
it does not solve the problem.

Of topic, but yeah I agree. You know the only problem is you could use
the other shells, but Sun only provides sh statically linked (and in
a bad situation that is _so_ very important.
