F-Script is a set of open source tools for dynamic introspection, manipulation and scripting of Cocoa objects on Mac OS X.
F-Script heavily depends on frameworks available in the system. There is a scheme for each release of Mac OS X:
Each scheme consists of app and frameworks that a linked against all relevent frameworks available in the system. I highly suggest you to use app that is specifically build for you version of Mac OS X.
If functional you need is missing but you're ready to pay for it, feel free to contact me. If not, create an issue anyway, I'll take a look as soon as I can.
