GNU Smalltalk is an implementation that closely follows the
Smalltalk-80 language as described in the book `Smalltalk-80: the
Language and its Implementation' by Adele Goldberg and David Robson.
The Smalltalk programming language is an object oriented programming
language.
Unlike other Smalltalks (including Smalltalk-80), GNU Smalltalk
emphasizes Smalltalk's rapid prototyping features rather than the
graphical and easy-to-use nature of the programming environment.
Therefore, even though we have a nice GUI environment including a class
browser, the goal of the GNU Smalltalk project is currently to produce a
complete system to be used to write your scripts in a clear, aesthetically
pleasing, and philosophically appealing programming language.
