llwin32helper has added environment entries and files so that CPAN/CPANPLUS
installs future modules to $answer.
To use modules installed this way in your scripts, insert this line:
use local::lib '~\\perl5';
(if you changed the directory, use that directory instead.)
To remove these environment entries, run llw32helper again.
You'll need to reboot for these environment variables to register.
