-    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.
