      use Data::Address::Standardize;
      # Read in a pipe-delimited data set like a filter.
      while(<>) {

DESCRIPTION
    The United States Postal Service (USPS) has on its web site an
    HTML form at
    `http://www.usps.gov/ncsc/lookups/lookup_zip+4.html' for
    standardizing an address. Given a firm, urbanization, street
    address, city, state, and zip, it will put the address into
    standard form (provided the address is in their database) and
    display a page with the resulting address.

    This Perl module provides a programmatic interface to this
    service, so you can write a program to process your entire
    personal address book without having to manually type them all
    in to the form.

    Because the USPS could change or remove this functionality at
    any time, be prepared for the possibility that this code may
    fail to function. In fact, as of this version, there is no error
    checking in place, so if they do change things, this code will
    most likely fail in a noisy way. If you discover that the
    service has changed, please email the author your findings.

    CODE IN A WAY THAT VIOLATES THE TERMS OF USE.

    The author believes that the example usage given above does not
    violate these terms, but sole responsibility for conforming to
    the terms of use belongs to the user of this code, not the
