=head1 DESCRIPTION
You can think of a module as the fundamental unit of reusable Perl
-code; See L<perlmod> for details. Whenever anyone creates a chunk
-of Perl code that they think will be useful to the world, they
-register as a Perl developer at
-http://www.perl.com/CPAN/modules/04pause.html so that they can then
-upload their code to CPAN. CPAN is the Comprehensive Perl Archive
-Network and can be accessed at http://www.perl.com/CPAN/, or searched
-via http://cpan.perl.com/ and
-http://theory.uwinnipeg.ca/mod_perl/cpan-search.pl .

This documentation is for people who want to download CPAN modules
and install them on their own computer.

-You have a file ending in F<.tar.gz> (or, less often, F<.zip>).
-You know there's a tasty module inside. You must now take four
-steps:
+First, are you sure that the module isn't already on your system? Try
+C<perl -MFoo -e 1>. (Replace "Foo" with the name of the module; for
+instance, C<perl -MCGI::Carp -e 1>.
+
+If you don't see an error message, you have the module. (If you do
+see an error message, it's still possible you have the module, but
+that it's not in your path, which you can display with C<perl -e
+"print qq(@INC)">.) For the remainder of this document, we'll assume
+that you really honestly truly lack an installed module, but have
+found it on the CPAN.
+
+So now you have a file ending in .tar.gz (or, less often, .zip). You
+know there's a tasty module inside. There are four steps you must now
