To find out all modules installed on your system, including those without documentation or outside the standard release, just use
       the following command (under the default win32 shell, double quotes should be used instead of single quotes).

           % perl -MFile::Find=find -MFile::Spec::Functions -Tlwe \
             'find { wanted => sub { print canonpath $_ if /\.pm\z/ },
             no_chdir => 1 }, @INC'
