I think "my" variables won't work if you want to set them from another
file, but I don't remember exactly. e.g.

==== main ====
my ($foo, $bar);
require "globals.pl";
print "foo=$foo bar=$bar\n";
==============

==== globals.pl ====
$foo = 1;
$bar = "sheep";
====================

I don't think this will work, but I think it will if you use "use vars"
instead.  That's the only difference I recall coming across, so I always
use "my" except in cases like the above.
