=head1 NAME

Finance::Quote::Bourso Obtain quotes from Boursorama.

=head1 SYNOPSIS

    use Finance::Quote;

    $q = Finance::Quote->new;

    %info = Finance::Quote->fetch("bourso","ml");  # Only query Bourso
    %info = Finance::Quote->fetch("france","af"); # Failover to other sources OK.

=head1 DESCRIPTION

This module fetches information from the "Paris Stock Exchange",
http://www.boursorama.com. 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 "bourso" in the argument
list to Finance::Quote->new().

This module provides both the "bourso" and "france" fetch methods.
Please use the "france" fetch method if you wish to have failover
with future sources for French stocks. Using the "bourso" method
will guarantee that your information only comes from the Paris Stock Exchange.

Information obtained by this module may be covered by www.boursorama.com
terms and conditions See http://www.boursorama.com/ for details.

=head1 LABELS RETURNED

The following labels may be returned by Finance::Quote::Bourso :
name, last, date, p_change, open, high, low, close, nav,
volume, currency, method, exchange, symbol.
