=head1 NAME

Telephone::Lookup::Americom - Lookup area, exchange, service provider, etc. information from Americom.

=head1 SYNOPSIS

  use Telephone::Lookup::Americom;
  my $am = Telephone::Lookup::Americom->new();
  my @res = $am->lookup('212-555-1212');

=head1 DESCRIPTION

This module uses Americom Area Decoder (http://decoder.americom.com/) to lookup information about a phone number.  It parses the return form and returns a list of hash refs, one for each record found.

  my @res = $am->lookup('212');           ## lookup only area code
  my @res = $am->lookup('212-555');       ## area code and exchange
  my @res = $am->lookup('212-555-1212');  ## or full phone number

  ## The form also seems to accpept numbers of the form '2125551212' and '(212) 555-1212'. 

  ## The module can return two datatypes:
  for my $record (@res) {
	if ($record->{_type} eq 'AREA_CODE'} {
		# The fields are:
                # $record->{'area_code', 'location', 'created_on'}
	}
	elsif ($record->{_type} eq 'EXCHANGE_CODE') {
		# The fields are: exchange_location, exchange_type, exchange_owner, created_on
	}
  }
