-=head1 About the perlfaq documents
-
-=head2 Where to get the perlfaq
-
-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/ .
-
-=head2 How to contribute to the perlfaq
-
-You may mail corrections, additions, and suggestions to
-perlfaq-suggestions@perl.com .  This alias should not be 
-used to I<ask> FAQs.  It's for fixing the current FAQ.
-Send questions to the comp.lang.perl.misc newsgroup.
-
-=head2 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.
-
-=head1 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.
