Imagine you go on holidays with your friends and every one of you pays bills for a subset of the the whole group. Now imagine further, there was a tool which helps you to divide your debts fair and conveniently.
Here it is. Just change bill.py according to your needs and run billsplit. It splits each bill according to the people involved and resolves payments to n-1 transactions, if there are n people involved. Each person gets a personal bill to get an overview over his/her expenses.
