==Getting To The CPAN Prompt==
To administer your Perl modules you must use the CPAN prompt. To get to the CPAN prompt, <b>as root</b> type:

::<code>perl -MCPAN -e shell</code>

If this is the first time that you have entered the CPAN shell, you will be asked some set-up questions that will allow the shell to access CPAN's servers to get modules. Just read the questions and answer them.

If you ever need to re-run the set-up again, enter the CPAN shell and then type:

::<code>o conf init</code>

==Listing The Installed Modules==
As of Slackware 10.2 and Perl 5.8.7- you can look the <code>perllocal.pod</code> file and see the modules.

::<code>cat /usr/lib/perl5/5.8.7/i486-linux/perllocal.pod</code>

A much cleaner way is by using this Perl program:

::<code>#!/usr/bin/perl</code>
::<code>use ExtUtils::Installed;</code>
::<code>my $instmod = ExtUtils::Installed->new();</code>
::<code>foreach my $module ($instmod->modules())</code>
:::<code>{</code>
:::<code>my $version = $instmod->version($module) || "???";</code>
:::<code>print "$module -- $version\n";</code>
:::<code>}</code>

==Installing New Modules==
From the CPAN shell prompt, type:

::<code>install <Some::Module></code>

==Removing Modules==

A clean way is by using this Perl program:

::<code>#!/usr/bin/perl -w</code>
::<code>use ExtUtils::Packlist;</code>
::<code>use ExtUtils::Installed;</code>
::<code>$ARGV[0] or die "Usage: $0 Module::Name\n";</code>
::<code>my $mod = $ARGV[0];</code>
::<code>my $inst = ExtUtils::Installed->new();</code>
::<code>foreach my $item (sort($inst->files($mod)))</code>
:::<code>{</code>
:::<code>print "removing $item\n";</code>
:::<code>unlink $item;</code>
:::<code>}</code>
::<code>my $packfile = $inst->packlist($mod)->packlist_file();</code>
::<code>print "removing $packfile\n";</code>
::<code>unlink $packfile;</code>
