The Scheme package is a Java library implementation of the scheme language. It is designed so that you can easily use it in a Java application or applet to make it extensible.
Bigloo is a Scheme implementation devoted to one goal: enabling Scheme based programming style where C(++) is usually required. Bigloo attempts to make Scheme practical by offering features usually presented by traditional programming languages but not offered by Scheme and functional programming. Bigloo compiles Scheme modules. It delivers small and fast stand alone binary executables. Bigloo enables full connections between Scheme and C programs, between Scheme and Java programs, and between Scheme and C# programs. (Use the version flagged as “Win32 precompiled version relying exclusively on the JVM back-end” for JVM version. Please inform me if you detect problems with its execution on platforms other than Win32. RT)
