libparams-check-perl 0.26-2 (i386 binary) in ubuntu intrepid

 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
