Connects to a set of URLs to extract the price value in them, performing currency conversion (if applies), and printing a CSV-like formatted output with the result.
A file called '.getprice.yaml' must be present in the home directory, following the structure:
item_name:
url: https://my.store.com/path/to/the/article
tag_id: priceblock # the HTML tag you want to capture
site_name: your site name # simply for tracking purposes
currency: EUR # default is EUR. Other values will be
# converted to EUR (i.e.: GBP)
If the currency is other than the default currency or not present, then it is converted using the latest available change rate.
