=head1 Obituary
It is with great sadness we note that Kip Hampton passed away. Probably
best known as the author of the Perl & XML column on XML.com, he was a
core contributor to AxKit, ab XML server platform that became an Apache
Foundation project. He was a frequent speaker in the early days at
OSCON, and most recently at YAPC::NA in Madison. He was frequently on
irc.perl.org as `ubu`, generally in the #axkit-dahut community, the
group responsible for YAPC::NA Asheville in 2011.
Kip and his constant contributions to the community will be greatly missed.

=head1 Reporting Bugs
If you find what you think is a bug, you might check the perl bug database
at L<https://rt.perl.org/> . There may also be information at
L<http://www.perl.org/> , the Perl Home Page.
If you believe you have an unreported bug, please run the L<perlbug> program
included with your release. Be sure to trim your bug down to a tiny but
sufficient test case. Your bug report, along with the output of C<perl -V>,
will be sent off to perlbug@perl.org to be analysed by the Perl porting team.
If the bug you are reporting has security implications which make it
inappropriate to send to a publicly archived mailing list, then see
L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
for details of how to report the issue.
