description YAP Prolog compiler
long_description    \
        YAP is a high-performance Prolog compiler developed at    \
        CRACS/Universidade do Porto and at COPPE Sistemas/UFRJ.   \
        Its Prolog engine is based in the WAM (Warren Abstract    \
        Machine), with several optimizations for better           \
        performance. YAP follows the Edinburgh tradition, and     \
        is largely compatible with the ISO-Prolog standard and    \
        with Quintus and SICStus Prolog.
