=head1 DESCRIPTION
This section of the FAQ answers questions about where to find
-source and documentation for Perl, support and training, and
+source and documentation for Perl, support, and
related matters.
-=head2 What machines support Perl? Where do I get it?
-
-The standard release of Perl (the one maintained by the perl
-development team) is distributed only in source code form. You can
-find this at http://www.perl.com/CPAN/src/latest.tar.gz, which is a
-gzipped archive in POSIX tar format. This source builds with no
-porting whatsoever on most Unix systems (Perl's native environment),
-as well as Plan 9, VMS, QNX, OS/2, and the Amiga.
-
-Although it's rumored that the (imminent) 5.004 release may build
-on Windows NT, this is yet to be proven. Binary distributions
-for 32-bit Microsoft systems and for Apple systems can be found
-http://www.perl.com/CPAN/ports/ directory. Because these are not part of
-the standard distribution, they may and in fact do differ from the base
-Perl port in a variety of ways. You'll have to check their respective
-release notes to see just what the differences are. These differences
-can be either positive (e.g. extensions for the features of the particular
-platform that are not supported in the source release of perl) or negative
-(e.g. might be based upon a less current source release of perl).

-If you don't have a C compiler because for whatever reasons your
-vendor did not include one with your system, the best thing to do is
+=head2 What machines support perl? Where do I get it?
+
+The standard release of perl (the one maintained by the perl
+development team) is distributed only in source code form. You
+can find this at http://www.cpan.org/src/latest.tar.gz , which
+is in a standard Internet format (a gzipped archive in POSIX tar format).
+
+Perl builds and runs on a bewildering number of platforms. Virtually
+all known and current Unix derivatives are supported (perl's native
+platform), as are other systems like VMS, DOS, OS/2, Windows,
+QNX, BeOS, OS X, MPE/iX and the Amiga.
+
+Binary distributions for some proprietary platforms, including
+Apple systems, can be found http://www.cpan.org/ports/ directory.
+Because these are not part of the standard distribution, they may
+and in fact do differ from the base perl port in a variety of ways.
+You'll have to check their respective release notes to see just
+what the differences are. These differences can be either positive
+(e.g. extensions for the features of the particular platform that
+are not supported in the source release of perl) or negative (e.g.
+might be based upon a less current source release of perl).
+
+=head2 How can I get a binary version of perl?
+
+For Windows, ActiveState provides a pre-built Perl for free:
+
+ http://www.activestate.com/
+
+Sunfreeware.com provides binaries for many utilities, including
+Perl, for Solaris on both Intel and SPARC hardware:
+
+ http://www.sunfreeware.com/
+
+If you don't have a C compiler because your vendor for whatever
+reasons did not include one with your system, the best thing to do is
grab a binary version of gcc from the net and use that to compile perl
with. CPAN only has binaries for systems that are terribly hard to
get free compilers for, not for Unix systems.
-Your first stop should be http://www.perl.com/CPAN/ports to see what
-information is already available. A simple installation guide for
-MS-DOS is available at http://www.cs.ruu.nl/~piet/perl5dos.html , and
-similarly for Windows 3.1 at http://www.cs.ruu.nl/~piet/perlwin3.html
-.
+Some URLs that might help you are:
+
+ http://www.cpan.org/ports/
+ http://www.perl.com/pub/language/info/software.html
+
+Someone looking for a perl for Win16 might look to Laszlo Molnar's
+djgpp port in http://www.cpan.org/ports/#msdos , which comes with
+clear installation instructions. A simple installation guide for
+MS-DOS using Ilya Zakharevich's OS/2 port is available at
+http://www.cs.ruu.nl/%7Epiet/perl5dos.html
+and similarly for Windows 3.1 at http://www.cs.ruu.nl/%7Epiet/perlwin3.html .

Since you don't have a C compiler, you're doomed and your vendor

=head2 Is there an ISO or ANSI certified version of Perl?
=head2 Where can I get information on Perl?
-The complete Perl documentation is available with the perl
-distribution. If you have perl installed locally, you probably have
-the documentation installed as well: type C<man perl> if you're on a
-system resembling Unix. This will lead you to other important man
-pages. If you're not on a Unix system, access to the documentation
-will be different; for example, it might be only in HTML format. But

You might also try C<perldoc perl> in case your system doesn't
have a proper man command, or it's been misinstalled. If that doesn't
work, try looking in /usr/local/lib/perl5/pod for documentation.
-If all else fails, consult the CPAN/doc directory, which contains the
-complete documentation in various formats, including native pod,
-troff, html, and plain text. There's also a web page at
-http://www.perl.com/perl/info/documentation.html that might help.
+If all else fails, consult http://perldoc.perl.org/ which has the
+complete documentation in HTML and PDF format.
+
+Many good books have been written about Perl--see the section later in
+L<perlfaq2> for more details.

+=head2 What are the Perl newsgroups on Usenet? Where do I post questions?
-The now defunct comp.lang.perl newsgroup has been superseded by the

comp.lang.perl.modules Use and development of Perl modules
comp.lang.perl.tk Using Tk (and X) from Perl
comp.infosystems.www.authoring.cgi Writing CGI scripts for the Web.
-There is also USENET gateway to the mailing list used by the crack
-Perl development team (perl5-porters) at

-=head2 Where should I post source code?
-
-You should post source code to whichever group is most appropriate,

-standards, including setting the Followup-To header line to NOT
-include alt.sources; see their FAQ for details.

-=head2 Perl Books
+Some years ago, comp.lang.perl was divided into those groups, and
+comp.lang.perl itself officially removed. While that group may still
+be found on some news servers, it is unwise to use it, because
+postings there will not appear on news servers which honour the
+official list of group names. Use comp.lang.perl.misc for topics
+which do not have a more-appropriate specific group.
-A number books on Perl and/or CGI programming are available. A few of
-these are good, some are ok, but many aren't worth your money. Tom
-Christiansen maintains a list of these books, some with extensive
-reviews, at http://www.perl.com/perl/critiques/index.html.
-
-The incontestably definitive reference book on Perl, written by the
-creator of Perl and his apostles, is now in its second edition and
-fourth printing.
-
- Programming Perl (the "Camel Book"):
- Authors: Larry Wall, Tom Christiansen, and Randal Schwartz
- ISBN 1-56592-149-6 (English)
- ISBN 4-89052-384-7 (Japanese)
- (French and German translations in progress)
-
-Note that O'Reilly books are color-coded: turquoise (some would call
-it teal) covers indicate perl5 coverage, while magenta (some would
-call it pink) covers indicate perl4 only. Check the cover color
-before you buy!
-
-What follows is a list of the books that the FAQ authors found personally
-useful. Your mileage may (but, we hope, probably won't) vary.
+There is also a Usenet gateway to Perl mailing lists sponsored by
+perl.org at nntp://nntp.perl.org , a web interface to the same lists
+at http://nntp.perl.org/group/ and these lists are also available
+under the C<perl.*> hierarchy at http://groups.google.com . Other
+groups are listed at http://lists.perl.org/ ( also known as
+http://lists.cpan.org/ ).
-If you're already a hardcore systems programmer, then the Camel Book
-just might suffice for you to learn Perl from. But if you're not,
-check out the "Llama Book". It currently doesn't cover perl5, but the
-2nd edition is nearly done and should be out by summer 97:
+A nice place to ask questions is the PerlMonks site,
+http://www.perlmonks.org/ , or the Perl Beginners mailing list
+http://lists.perl.org/showlist.cgi?name=beginners .
- Learning Perl (the Llama Book):
- Author: Randal Schwartz, with intro by Larry Wall
- ISBN 1-56592-042-2 (English)
- ISBN 4-89502-678-1 (Japanese)
- ISBN 2-84177-005-2 (French)
- ISBN 3-930673-08-8 (German)
+Note that none of the above are supposed to write your code for you:
+asking questions about particular problems or general advice is fine,
+but asking someone to write your code for free is not very cool.
-Another stand-out book in the turquoise O'Reilly Perl line is the "Hip
-Owls" book. It covers regular expressions inside and out, with quite a
-bit devoted exclusively to Perl:

+almost completely (although it sometimes sneaks in an article about
+another language).
+
+Magazines that frequently carry quality articles on Perl include I<The
+Perl Review> ( http://www.theperlreview.com ), I<Unix Review> (
+http://www.unixreview.com/ ), I<Linux Magazine> (
+http://www.linuxmagazine.com/ ), and Usenix's newsletter/magazine to
+its members, I<login:> ( http://www.usenix.org/ )
+
+The Perl columns of Randal L. Schwartz are available on the web at
+http://www.stonehenge.com/merlyn/WebTechniques/ ,
+http://www.stonehenge.com/merlyn/UnixReview/ , and
+http://www.stonehenge.com/merlyn/LinuxMag/ .
+
+The first (and for a long time, only) periodical devoted to All Things
+Perl, I<The Perl Journal> contains tutorials, demonstrations, case
+studies, announcements, contests, and much more. I<TPJ> has columns
+on web development, databases, Win32 Perl, graphical programming,
+regular expressions, and networking, and sponsors the Obfuscated Perl
+Contest and the Perl Poetry Contests. Beginning in November 2002, TPJ
+moved to a reader-supported monthly e-zine format in which subscribers
+can download issues as PDF documents. In 2006, TPJ merged with Dr.
+Dobbs Journal (online edition). To read old TPJ articles, see

+=head2 What mailing lists are there for Perl?
+
+Most of the major modules (Tk, CGI, libwww-perl) have their own
+mailing lists. Consult the documentation that came with the module for
+subscription information.
- unsubscribe Perl-Win32-Users
+A comprehensive list of Perl related mailing lists can be found at:
-You can also check http://www.activeware.com/ and select "Mailing Lists"
-to join or leave this list.
+ http://lists.perl.org/
-=item Perl-Packrats
+=head2 Where are the archives for comp.lang.perl.misc?
-Discussion related to archiving of perl materials, particularly the
-Comprehensive PerlArchive Network (CPAN). Subscribe by emailing
-majordomo@cis.ufl.edu:
+The Google search engine now carries archived and searchable newsgroup
+content.
- subscribe perl-packrats
+http://groups.google.com/groups?group=comp.lang.perl.misc
-The list software, also written in perl, will automatically determine
-your address, and subscribe you automatically. To unsubscribe, simple
-prepend the same command with an "un", and mail to the same address
-like so:
+If you have a question, you can be sure someone has already asked the
+same question at some point on c.l.p.m. It requires some time and patience
+to sift through all the content but often you will find the answer you
+seek.

+=head2 Where can I buy a commercial version of perl?
-=back
+In a real sense, perl already I<is> commercial software: it has a license
+that you can grab and carefully read to your manager. It is distributed
+in releases and comes in well-defined packages. There is a very large
+user community and an extensive literature. The comp.lang.perl.*
+newsgroups and several of the mailing lists provide free answers to your
+questions in near real-time. Perl has traditionally been supported by
+Larry, scores of software designers and developers, and myriad
+programmers, all working for free to create a useful thing to make life
+better for everyone.
-=head2 Archives of comp.lang.perl.misc
+However, these answers may not suffice for managers who require a
+purchase order from a company whom they can sue should anything go awry.
+Or maybe they need very serious hand-holding and contractual obligations.
+Shrink-wrapped CDs with perl on them are available from several sources if
+that will help. For example, many Perl books include a distribution of perl,
+as do the O'Reilly Perl Resource Kits (in both the Unix flavor
+and in the proprietary Microsoft flavor); the free Unix distributions
+also all come with perl.
-Have you tried Deja News or Alta Vista?
+=head2 Where do I send bug reports?
-ftp.cis.ufl.edu:/pub/perl/comp.lang.perl.*/monthly has an almost
-complete collection dating back to 12/89 (missing 08/91 through
-12/93). They are kept as one large file for each month.
+If you are reporting a bug in the perl interpreter or the modules
+shipped with Perl, use the I<perlbug> program in the Perl distribution or
+mail your report to perlbug@perl.org or at http://rt.perl.org/perlbug/ .
-You'll probably want more a sophisticated query and retrieval mechanism
-than a file listing, preferably one that allows you to retrieve
-articles using a fast-access indices, keyed on at least author, date,
-subject, thread (as in "trn") and probably keywords. The best
-solution the FAQ authors know of is the MH pick command, but it is
-very slow to select on 18000 articles.
+For Perl modules, you can submit bug reports to the Request Tracker set
+up at http://rt.cpan.org .
-If you have, or know where can be found, the missing sections, please
-let perlfaq-suggestions@perl.com know.
+If you are posting a bug with a non-standard port (see the answer to
+"What platforms is perl available for?"), a binary distribution, or a
+non-standard module (such as Tk, CGI, etc), then please see the
+documentation that came with it to determine the correct place to post
+bugs.
-=head2 Perl Training
+Read the perlbug(1) man page (perl5.004 or later) for more information.
-While some large training companies offer their own courses on Perl,
-you may prefer to contact individuals near and dear to the heart of
-Perl development. Two well-known members of the Perl development team
-who offer such things are Tom Christiansen <perl-classes@perl.com>
-and Randal Schwartz <perl-training-info@stonehenge.com>, plus their
-respective minions, who offer a variety of professional tutorials
-and seminars on Perl. These courses include large public seminars,
-private corporate training, and fly-ins to Colorado and Oregon.
-See http://www.perl.com/perl/info/training.html for more details.

+The Perl Foundation is an advocacy organization for the Perl language

-Instead, the Paul Ingram Group will be taking up the slack through The
-Perl Clinic. The following is a commercial from them:

-"Do you need professional support for Perl and/or Oraperl? Do you need
-a support contract with defined levels of service? Do you want to pay
-only for what you need?
-
-"The Paul Ingram Group has provided quality software development and
-support services to some of the world's largest corporations for ten
-years. We are now offering the same quality support services for Perl
-at The Perl Clinic. This service is led by Tim Bunce, an active perl
-porter since 1994 and well known as the author and maintainer of the
-DBI, DBD::Oracle, and Oraperl modules and author/co-maintainer of The
-Perl 5 Module List. We also offer Oracle users support for Perl5
-Oraperl and related modules (which Oracle is planning to ship as part
-of Oracle Web Server 3). 20% of the profit from our Perl support work
-will be donated to The Perl Institute."

-=head2 What is perl.com? perl.org? The Perl Institute?
+Revision: $Revision: 7996 $
-perl.org is the official vehicle for The Perl Institute. The motto of
-TPI is "helping people help Perl help people" (or something like
-that). It's a nonprofit organization supporting development,
-documentation, and dissemination of perl. Current directors of TPI
-include Larry Wall, Tom Christiansen, and Randal Schwartz, whom you
-may have heard of somewhere else around here.

-The perl.com domain is Tom Christiansen's domain. He created it as a
-public service long before perl.org came about. It's the original PBS
-of the Perl world, a clearinghouse for information about all things
-Perlian, accepting no paid advertisements, glossy GIFs, or (gasp!)
-Java applets on its pages.
