perl5.002beta3

[editor's note: no patch file was found for this release, so no
fine-grained changes]

I can't find the password for our ftp server, so I had to drop it into
ftp://ftp.sems.com/pub/incoming/perl5.002b3.tar.gz, which is a drop
directory you can't ls.

The current plan is that Andy is gonna whack on this a little more, and
then release a gamma in a few days when he's happy with it.  So don't get
carried away.  This is now *late* beta.

In other words, have less than the appropriate amount of fun.  :-)
