This is a release to allow an easy way to come back to the PHP implementation of the whole service. This includes a web service sample implementation as well. Note that this implementation fails to work due to Receita's modifications to their captcha system.
The following version will be focused on a simple Python implementation of a web service client only. There will be no code that effectively retrieves data. The web service will still work, but the code will not be freely available due to the aforementioned issues.
