| 79 | |
| 80 | If you find what you think is a bug, you might check the articles |
| 81 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
| 82 | bug database at http://bugs.perl.org/ . There may also be |
| 83 | information at http://www.perl.org/ , the Perl Home Page. |
| 84 | |
| 85 | If you believe you have an unreported bug, please run the B<perlbug> |
| 86 | program included with your release. Be sure to trim your bug down |
| 87 | to a tiny but sufficient test case. Your bug report, along with the |
| 88 | output of C<perl -V>, will be sent off to perlbug@perl.org to be |
| 89 | analysed by the Perl porting team. |
