First, thanks for you helpful input and examples.
I'm taxing peoples patience I suppose but being considerably thick of
skull I cannot just look at this and see what it does.

my @files = map { $_->[0] } # What happened there?
sort { $a cmp $b } # I now this sorts stuff, but not sure how or
# what kind of sort
perldoc -f cmp Tells you only to find the meaning in perlop
perldoc perlop - /cmp
Looking at every appearance of `cmp'... I still do not know what the
heck it does. I did find out that it returns 1 or 0. Seems kind of
thin to help me understand what it does.
map {[$_, (stat("$dir/$_"))[9] ] } ## I see a stat is done and
# modtime extracted what else
# happens here?
