This is a tool to create billing for contractual work from MS Outlook data written in Python. The software looks for appointments with a specified title between two dates. Then it outputs when and how long you worked on the project in a MS Excel sheet.
You have to install ActivePython 2.3 (or higher) and wxPython 2.5 (or higher) before you can run the software.
