+		CHICKEN is a compiler for the Scheme programming language.
+		CHICKEN produces portable, efficient C, supports almost all of
+		the current Scheme language standard, the Revised5 Report on
+		the Algorithmic Language Scheme (R5RS ), and includes many enhancements
+		and extensions. CHICKEN runs on MacOS X, Windows, and many Unix flavours.
