GNU Smalltalk is an implementation of the Smalltalk programming language by the GNU Project.
The implementation, unlike other Smalltalk environments, uses text files for program input and interprets the contents as Smalltalk code. In this way, GNU Smalltalk acts more like an interpreter rather than an environment in the traditional Smalltalk manner.
GNU Smalltalk includes bindings for many free software libraries including SQLite, libSDL, cairo, gettext, Expat.
