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 please send -it to perl5-security-report@perl.org. This points to a closed subscription -unarchived mailing list, which includes -all the core committers, who will be able -to help assess the impact of issues, figure out a resolution, and help -co-ordinate the release of patches to mitigate or fix the problem across all -platforms on which Perl is supported. Please only use this address for -security issues in the Perl core, not for modules independently -distributed on CPAN. - -=head1 SEE ALSO - -The F<Changes> file for an explanation of how to view exhaustive details -on what changed. - -The F<INSTALL> file for how to build Perl. - -The F<README> file for general stuff. - -The F<Artistic> and F<Copying> files for copyright information. - -=cut - |
