NAME
    Geography::States - Map states and provinces to their codes, and vica
    versa.

SYNOPSIS
     use Geography::States;

     my $obj = Geography::States -> new (COUNTRY [, STRICT]);

EXAMPLES
     my $canada = Geography::States -> new ('Canada');

     my  $name          =  $canada -> state ('NF');      # Newfoundland.
     my  $code          =  $canada -> state ('Ontario'); # ON.
     my ($code, $name)  =  $canada -> state ('BC');      # BC, British Columbia.
     my  @all_states    =  $canada -> state;             # List code/name pairs.

DESCRIPTION
    This module lets you map states and provinces to their codes, and codes
    to names of provinces and states.

    The "Geography::States -" new ()> call takes 1 or 2 arguments. The
    first, required, argument is the country we are interested in. Current
    supported countries are *USA*, *Brazil*, *Canada*, *The Netherlands*,
    and *Australia*. If a second non-false argument is given, we use *strict
    mode*. In non-strict mode, we will map territories and alternative codes
    as well, while we do not do that in strict mode. For example, if the
    country is USA, in non-strict mode, we will map GU to Guam, while in
    strict mode, neither GU and Guam will be found.

  The state() method
    All queries are done by calling the "state" method in the object. This
    method takes an optional argument. If an argument is given, then in
    scalar context, it will return the name of the state if a code of a
    state is given, and the code of a state, if the argument of the method
    is a name of a state. In list context, both the code and the state will
    be returned.

    If no argument is given, then the "state" method in list context will
    return a list of all code/name pairs for that country. In scalar
    context, it will return the number of code/name pairs. Each code/name
    pair is a 2 element anonymous array.

    Arguments can be given in a case insensitive way; if a name consists of
    multiple parts, the number of spaces does not matter, as long as there
    is some whitespace. (That is "NewYork" is wrong, but "new    YORK" is
    fine.)

ODDITIES AND OPEN QUESTIONS
    I found conflicting abbreviations for the US *Northern Mariana Islands*,
    listed as *NI* and *MP*. I picked *MP* from the USPS site.

    One site listed *Midway Islands* as having code *MD*. It is not listed
    by the USPS site, and because it conflicts with *Maryland*, it is not
    put in this listing.

    The USPS also has so-called *Military "States"*, with non-unique codes.
    Those are not listed here.

    Canada's *Quebec* has two codes, the older *PQ* and the modern *QC*.
    Both *PQ* and *QC* will map to *Quebec*, but *Quebec* will only map to
    *QC*. With strict mode, *PQ* will not be listed. Similary, Newfoundland
    has an old code *NF*, and a new code *NL* (the province is now called
    *Newfoundland and Labrador*).
