217 | ||
218 | If you find what you think is a bug, you might check the articles | |
219 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
220 | bug database at http://bugs.perl.org. There may also be | |
221 | information at http://www.perl.com/, the Perl Home Page. | |
222 | ||
223 | If you believe you have an unreported bug, please run the B<perlbug> | |
224 | program included with your release. Be sure to trim your bug down | |
225 | to a tiny but sufficient test case. Your bug report, along with the | |
226 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
227 | analysed by the Perl porting team. | |
