-		Gerbil is an opinionated dialect of Scheme designed
-		for Systems 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 (Racket) modules. The main difference
-		from Racket is that Gerbil modules are single instantiation,
-		supporting high performance ahead of time compilation
-		and compiled macros.
