The following people are known to have contributed the improvements that became\nPerl 5.16.3:\n\nAndy Dougherty, Chris 'BinGOs' Williams, Dave Rolsky, David Mitchell, Michael Schroeder,\nRicardo Signes, Yves Orton.\n\nThe list above is almost certainly incomplete as it is automatically generated from version\ncontrol history. In particular, it does not include the names of the (very much appreciated)\ncontributors who reported issues to the Perl bug tracker.\n\nFor a more complete list of all of Perl's historical contributors, please see the AUTHORS\nfile in the Perl source distribution.\n",

Be sure to trim your bug down to a tiny but sufficient test case.  Your bug report,\nalong with the output of \"perl -V\", will be sent off to perlbug@perl.org to be analysed by\nthe Perl porting team.\n\nIf the bug you are reporting has security implications, which make it inappropriate to send\nto a publicly archived mailing list, then please send it to perl5-security-report@perl.org.\nThis points to a closed subscription unarchived mailing list, which includes all the core\ncommitters, who will be able to help assess the impact of issues, figure out a resolution,\nand help co-ordinate the release of patches to mitigate or fix the problem across all\nplatforms on which Perl is supported. Please only use this address for security issues in the\nPerl core, not for modules independently distributed on CPAN.\n"
