Where to get this document
This document is posted regularly to comp.lang.perl.announce and
several other related newsgroups. It is available in a variety of
formats from CPAN in the /CPAN/doc/FAQs/FAQ/ directory, or on the web
at http://www.perl.com/perl/faq/ .
How to contribute to this document
You may mail corrections, additions, and suggestions to
perlfaq-suggestions@perl.com . Mail sent to the old perlfaq alias
will merely cause the FAQ to be sent to you.
What will happen if you mail your Perl programming problems to the authors
Your questions will probably go unread, unless they're suggestions of
new questions to add to the FAQ, in which case they should have gone
to the perlfaq-suggestions@perl.com instead.
You should have read section 2 of this faq. There you would have
learned that comp.lang.perl.misc is the appropriate place to go for
free advice. If your question is really important and you require a
prompt and correct answer, you should hire a consultant.
Credits
When I first began the Perl FAQ in the late 80s, I never realized it
would have grown to over a hundred pages, nor that Perl would ever become
so popular and widespread. This document could not have been written
without the tremendous help provided by Larry Wall and the rest of the
Perl Porters.
