Is "WorldText" open source?


cocoa love
Hi how are you doing. i was playing around with what apple has and in "Developer/Applications/Extras/" and i opened "WorldText" for the hell of it. After looking at it twice, i noticed that it does alot of stuff that I want one of my apps I'm building to do. "Sketch" that is also in the "Extras" folder is open source, but does anyone know if "WorldText" is? And if so where i can find it? All feedback is welcome and appreciated.
