=head1 SYNOPSIS

    use Finance::Quote;

    $q = Finance::Quote->new;

    %info = Finance::Quote->fetch("bossa","AROK");  # Only query Bossa.pl
    %info = Finance::Quote->fetch("poland","AROK"); # Failover to other sources OK.

=head1 DESCRIPTION

This module fetches information from http://www.bossa.pl/ Polish stock
market service. All stocks are available.

This module is loaded by default on a Finance::Quote object. It's
also possible to load it explicity by placing "Bossa" in the argument
list to Finance::Quote->new().

This module provides both the "bossa" and "poland" fetch methods.

with future sources for Polish stocks. Using the "bossa" method
will guarantee that your information only comes from the Bossa.pl
service.
