	If you're ever wondering about one of the builtin perl
variables, just consult:

man perlvar

(or `perldoc perlvar' if your man doesn't find the perl manual pages)

	If you're ever wondering what man page to look at to find
something out about perl, man perl will give a listing of them all.
And man perltoc is also helpful (has headings from pretty much all
docs that ship standard with perl).
