The reason I nudged was because reading man pages should always have
all of the details anyone would ever need.  However that only works if
one already knows how things work.  Reference documents may have all
of the details but it is nice to read tutorials and HOWTOs that
guide, explain and tutor people through with overall conclusions.  By
the very nature of them they make judgments.  Reference docs have
facts but being able to put the rationale of the decision making into
place around those facts is still valuable.  You seem to have a good
grasp of the problem space and as I said I would have enjoyed reading
any of your tutorials on it.  If there aren't any written then that is
okay too.

But in any case.  All is okay.  Thanks! :-)
