Various other “minor” packages are provided, typically as examples of writing modules for GNU Smalltalk (see Linking your libraries to the virtual machine). These include:
which adds transparent operations with complex numbers
which is an interface to the GNU database manager
which provides two easy to use classes to quickly compute cryptographically strong hash values using the MD5 and SHA1 algorithms.
which provides bindings to ncurses
which provides more examples and tests for continuations (an advanced feature to support complex control flow).
which provides a way to attach to another Smalltalk process and execute it a bytecode or a method at a time.
