+Programming, with a state of the art macro and module system on top of the Gambit
+runtime.  The macro system is based on quote-syntax, and provides the full meta-syntactic
+tower with a native implementation of syntax-case.  It also provides a full-blown module
+system, similar to PLT Scheme's (sorry, Racket) modules.  The main difference from Racket
+is that Gerbil modules are single instantiation, supporting high performance ahead of
+time compilation and compiled macros.")
