This script will allow you to keep track of your gas mileage and have the results displayed in an easy to read website. None of the data is harvested from anywhere on the web but is rather entered manually by the user and for the user.
Currently the program only supports the English system of miles and gallons. Future versions intend to include the metric system as well as conversions between the figures.
If the demand seems to exist, a future version will allow the user to import a CSV file (or something similar). This should satisfy any users who have historically kept up with such data with Excel and other spreadsheets.
