$PRGNAM: $PRGNAM (Scheme programming system)
$PRGNAM:
$PRGNAM: Gambit-C includes a Scheme interpreter and a Scheme compiler which can be used
$PRGNAM: to build standalone executables.  Because the compiler generates portable
$PRGNAM: C code it is fairly easy to port to any platform with a decent C compiler.
$PRGNAM: 
$PRGNAM: The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards.
