Web (recipe) scraping app that converts result (HTML) to a standard

We're looking to make an app that can backup recipes from a service (MealBoard) and keep it in a standardized format. This will mean: * Log into site * Get list of recipes * Pull each recipe (1 page/recipe) * Parse HTML of the recipe and convert it to an open format ([login to view URL]'s recipe format). The format has info and examples on [login to view URL] (the microdata format example in particular) or [login to view URL] for an alternate example. An example source recipe is attached. The source HTML should be saved to a temporary location to make comparing recipes easier for validation - the cleanup of these will be handled externally. This is intended to be run periodically via a cron job, so needs to be able to be run without direct input on a schedule - everything needed should be in config files or via command line args. Password and username should be able to be loaded from environment variables. The Python script should be well formatted and documented - conforming to all PEP8 and PEP257 checks. I want code that can be shared and maintained, and am not looking for something just quickly put together that solely does the job now.
