You get an Object (Data structure) of a Receipt (bill) which provides data for the PDF file, which is to be created/shown dynamically.
As a guideline you will get a Bill (a scan or in PDF) and the resulted output from ruby has to look similar to that one.
Also some simple reports (<= 2) needed.
The process will be the same. You'll get a data structure and the pdf output should be a table.
All required sources will be provided as a test-unit soon.
Please feel free to write me some questions if there are any.
