Duckworth-Lewis calculator description

This application calculates Duckworth-Lewis (D/L) par scores and targets for rain-interrupted limited-overs cricket matches. It uses the 'Standard Edition' of the D/L method. This will not give exactly the same answer as the 'Professional Edition' that is used in professional matches. (Use of the Professional Edition requires proprietary software which is not yet available to the general public.) However, this application will provide a good indicator of the state of play in a match, and the Standard Edition is valid in non-professional matches (or where the professional software is not available).
