今天是圣诞节，是个感恩的节日。
于此同时，我们应当对 perl 的开发者致以最好的祝福。
从 perl-5.8.9 开始，perl 都开始带有一个 perlthanks 的小程序，该程序将给 perl-porter 新闻组发送感谢信。
如果您的 perl 版本小于 5.8.9, 那么可以遵循如下步骤来发送。
$ wget http://search.cpan.org/CPAN/authors/id/L/LB/LBROCARD/perl-5.11.2.tar.bz2
$ tar xvjf perl-5.11.2.tar.bz2
$ cd perl-5.11.2/utils
$ perl perlbug.PL
$ perl perlbug -T
perlbug -T 或者 perlthanks 启动之后，您就可以编写标题和内容，然后就发送了，非常简单。
This program provides an easy way to send a thank-you message
back to the authors and maintainers of perl.
If you wish to submit a bug report, please run it without the -T
flag (or run the program perlbug rather than perlthanks)
First of all, please provide a subject for the message.
Subject: Merry Christmas!
Perl's developers may need your email address to contact you for
further information about your issue or to inform you when it is
resolved. If the default shown is not your email address,
please correct it.
Your address [fayland@perl]: fayland@gmail.com
perlbug can send a copy of this report to your local perl
administrator. If the address below is wrong, please correct
it, or enter 'none' or 'yourself' to not send a copy.
Local perl administrator [root@localhost]: none
It's now time to compose your thank-you message.
Some information about your local perl configuration will
automatically be included at the end of your message, because
we're curious about the different ways that people build and use
perl. If you'd rather not share this information, you're welcome
to delete it.
You will probably want to use a text editor to enter the body of
your report. If "vi" is the editor you want to use, then just
press Enter, otherwise type in the name of the editor you would
like to use.
If you have already composed the body of your report, you may
enter "file", and perlbug will prompt you to enter the name of
the file containing your report.
Editor [vi]: vi
This is a thank-you report for perl from fayland@gmail.com,
generated with the help of perlbug 1.39 running under perl 5.8.8.

=============================================
结后语：
至此，2009 的 CN Perl Advent Calendar 就结束了。
感谢 cnhackTNT, Joe Jiang 和 Alexe, 没有你们，这会是一个孤单的十二月。
特别感谢我的妻子对我默默地支持，即使在我儿子生病的时候还能让我来抽空完成这项任务。谢谢。
最后，祝大家在新的一年里工作顺利，世事顺心。
谢谢，来年再会。
