+    Chez Scheme is both a programming language and an implementation
+    of that language, with supporting tools and documentation.
+
+    As a superset of the language described in the Revised6 Report on
+    the Algorithmic Language Scheme (R6RS), Chez Scheme supports all
+    standard features of Scheme, including first-class procedures,
+    proper treatment of tail calls, continuations, user-defined
+    records, libraries, exceptions, and hygienic macro expansion.
+
+    Chez Scheme also includes extensive support for interfacing with C
+    and other languages, support for multiple threads possibly running
+    on multiple cores, non-blocking I/O, and many other features.
