=head1 NAME

Finance::Quote::ASEGR Obtain quotes from Athens Stock Exchange.

=head1 SYNOPSIS

    use Finance::Quote;

    $q = Finance::Quote->new;

    %info = Finance::Quote->fetch("asegr","minoa");  # Only query ASEGR
    %info = Finance::Quote->fetch("greece","aaak"); # Failover to other sources OK. 

=head1 DESCRIPTION

This module fetches information from the "Athens Stock Exchange",
http://www.ase.gr. 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 "ASEGR" in the argument
list to Finance::Quote->new().

This module provides both the "asegr" and "greece" fetch methods.
Please use the "greece" fetch method if you wish to have failover
with future sources for Greek stocks. Using the "asegr" method
will guarantee that your information only comes from the Athens Stock Exchange.
 
Information obtained by this module may be covered by www.ase.gr 
terms and conditions See http://www.ase.gr/ for details.

=head1 LABELS RETURNED

The following labels may be returned by Finance::Quote::ASEGR :
name, last, date, p_change, open, high, low, close, 
volume, currency, method, exchange.
