Developer Philippe Mougin has updated F-Script
(http://www.fscript.org), an open-source scripting language
specifically designed for Cocoa (Apple’s object-oriented development
system), to version 2.0. The new version sports such new features as
system-wide scripting, dynamic Cocoa class creation, 64-bit support
and automatic garbage collection.

F-Script provides interactive and scripting access to Cocoa objects
through a graphical environment and a high-level programming model.
It allows interactive exploration, testing and use of Cocoa-based
objects and frameworks. F-Script can be used as a stand-alone tool,
embedded into other applications or dynamically injected into any
Cocoa application. It’s released free of charge, as open-source
software.
