*** THIS IS ALPHA SOFTWARE ***

This module implements the Address Standardization web service from the US Postal Service. It is a subclass of Business::US::USPS::WebTools.

lookup_city_state( KEY, VALUE, ... )

The verify_address method takes the following keys, which come directly from the USPS web service interface:

	FirmName	The name of the company
	Address1	The suite or apartment
	Address2	The street address
	City		The name of the city
	State		The two letter state abbreviation
	Zip5		The 5 digit zip code
	Zip4		The 4 digit extension to the zip code

It returns an anonymous hash with the same keys, but the values are the USPS's canonicalized address. If there is an error, the hash values will be the empty string, and the error flag is set. Check is with is_error:

	$verifier->is_error;

See the is_error documentation in Business::US::USPS::WebTools for more details on error information.

If, for some reason, I disappear from the world, one of the other members of the project can shepherd this module appropriately.
