standardized, flexible, testable CLI applications framework for Perl

 CLI::Framework ("CLIF") provides a framework and conceptual pattern for
 building full-featured command line applications. It intends to make
 this process simple and consistent. It assumes the responsibility of
 implementing details that are common to all command-line applications,
 making it possible for new applications adhering to well-defined
 conventions to be built without the need to repeatedly write the same
 command-line interface code.
