Itemizes complex online (beer) orders.

Create (or copy-paste in) the order confirmation as TSV (tab-separated values). Name the columns:

• name - the name of the line item
• qty - total quantity of items on this line
• total - total for this line -- mutually exclusive with unit
• unit - unit price for this line -- mutually exclusive with total
• discount - a discount % for this line (0..1)
• tags - a string of tags for this line (one character = one tag).

(See examples/ for examples.)

Then run python billtag.py that_file.tsv, and voila!

Also see --help for additional options.
