+São 4 programinhas para calcular o valor do DARF a ser pago ao se receber
+ações GOOG através de GSU.
+
+Dependências:
+
+* [Python 3.2][py] ou mais recente
+* [dateutil][dateutil]
+* [lxml][lxml]
+
+[py]: http://python.org/
+[dateutil]: http://labix.org/python-dateutil
+[lxml]: http://lxml.de/
+
+exchangerate.py
+---------------
+
+Usa UOL e Google Finance para pegar o valor da ação GOOG em uma certa data e o
+valor do dólar no último dia útil da primeira quinzena do mês anterior.
+
+    ./exchangerate.py 20-Jan-2012
+	usdbrl@15-Dec-2011: 1.860800 goog@20-Jan-2012: 585.990000
+
+A data pode ser digitada em qualquer formato suportado pelo
+[`dateutil.parser.parse`][parse].

+
+tax.py
+------
+
+Realiza uma busca na tabela progressiva do imposto para fazer a mesma conta
+que o [carnê-leão][carneleao] faz.
+
+    ./tax.py 5000 2012-Jan
+    R$5000.000000 @Jan-2012 gives tax of R$618.470000
+
+O valor de entrada (no exemplo acima, 5000) corresponde à seguinte fórmula:
+
+    num. de ações × valor da ação × cotação do dólar
+
+[carneleao]: http://www.receita.fazenda.gov.br/PessoaFisica/CarneLeao/default.htm
+
+sicalc.py
+---------
+
+Recebe o valor de imposto e usa o sicalc para gerar o DARF.
+
+	# cpf com 12 dígitos, mês, valor
+    ./sicalc.py 12345678909 2012-Jan 618.47

+
+gsu_irpf.py
+-----------
+
+É a cola de todos os programas anteriores. Recebe o CPF e o arquivo CSV
+*transaction history* (exportado do [benefitaccess.com][mssb]) e gera todos os
+DARFs, incluindo multa e juros se aplicável. Basta apenas escolher os que não
+foram pagos e pagá-los.
