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.
