Default Rules Preprocessor ========================== This directory contains the implementation of a preprocessor for Curry programs in order to implement default rules. A default rule for a function `f` processed by this preprocessor must be defined as a rule defining the operation `f'default`. The preprocessor can be called by the Curry preprocessor `currypp` with the option `defaultrules` (provided as a CYMAKE option, see the example programs in the directory Examples).
