Declaratively Expressed Command-Line Arguments via Regular Expressions

Getopt::Declare is yet another command-line argument parser, one which is specifically designed to be powerful but exceptionally easy to use. To parse the command-line in @ARGV, one simply creates a Getopt::Declare object, by passing Getopt::Declare::new() a specification of the various parameters that may be encountered. The specification is a single string, in which the syntax of each parameter is declared, along with a description and (optionally) one or more actions to be performed when the parameter is encountered. The specification string may also include other usage formatting information (such as group headings or separators) as well as standard Perl comments (which are ignored).
