Evaluation
Ratings can take the form '+' which indicates that a particular tool or language provides direct support for the pattern involved, '+/-' which indicates that some limitations exists regaring direct support, and '-' which indicates that no direct support is provided. If support is not specified this is indicated by the label '0'.
