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.

-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:

+ActiveState: Windows, Linux, Mac OS X, Solaris, AIX and HP-UX
http://www.activestate.com/
-Sunfreeware.com provides binaries for many utilities, including
-Perl, for Solaris on both Intel and SPARC hardware:
+Sunfreeware.com: Solaris 2.5 to Solaris 10 (SPARC and x86)
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.

=head2 Perl Books
-A number of 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.
-There is a list of these books, some with extensive reviews, at
-http://books.perl.org/ . If you don't see your book listed here, you
-can write to perlfaq-workers@perl.org .

- with Foreword by Larry Wall
- ISBN 0-596-00313-7 [2nd Edition August 2003]
- http://www.oreilly.com/catalog/perlckbk2/
-
-If you're already a seasoned programmer, then the Camel Book might
-suffice for you to learn Perl. If you're not, check out the
-Llama book:

-Addison-Wesley ( http://www.awlonline.com/ ) and Manning
-( http://www.manning.com/ ) are also publishers of some fine Perl books
-such as I<Object Oriented Programming with Perl> by Damian Conway and
