Description:

Perl module Params::Check is a generic input parsing/checking
mechanism. It allows you to validate input via a template. The only
requirement is that the arguments must be named. Params::Check can do
the following things for you:
- Convert all keys to lowercase
- Check if all required arguments have been provided
- Set arguments that have not been provided to the default
- Weed out arguments that are not supported and warn about them to the
user
- Validate the arguments given by the user based on strings, regexes,
lists or even subroutines
- Enforce type integrity if required
