If you've had the pleasure of finding a perl script that takes care of your needs without needing to write it yourself – kudos to you! But, you might be slapped with a few "Can't locate module" errors when you attempt to run the script.
The error message looks worse than it actually is.
Using the cpan module manager, you can install virtually any module effortlessly. For instance, if you are getting the following error:
Can't locate HTML/Encoding.pm
Running:
cpan install HTML:Encoding
will download, compile and install the appropriate module by referencing various download sites.
