This module allows information to be fetched from Yahoo abouts stocks
traded on the Brasilian Stock Exchange.
This module is loaded by default on a Finance::Quote object, although
it can be explicitly loaded by passing the argument Yahoo::Brasil
This module provides both the brasil and yahoo_brasil fetch
methods. You should use the brasil method if you wish to allow
failovers to other sources, and yahoo_brasil if you only want
to obtain quotes from this module.
Information obtained via this module is governed by Yahoos terms
and conditions, see http://br.finance.yahoo.com/ for more details.
