So, hello there Joe Barbish,
we haven't had one of your selfpromotions of qjail at the expense of
ezjail, the belately acknowledged source of your code, for ages now.
Good to be reminded where you're still coming from, how you acknowledge
your sources, and how you continue to collaborate with your peers.
Michael Lucas, who you may not have been around long enough to know of,
is clearly seeking to research information, ideas and comments from his
peers and acknowledged betters in this field before rushing into print,
as we've come to expect. I wouldn't worry too much about him getting it
Thanks again Joe,
