The following files provide support for Objective-J syntax coloring and text completion in Xcode version 3 and above

	ObjectiveJ.xcspec
	ObjectiveJ.xclangspec
	ObjectiveJ.xctxtmacro

The above files were derived from the Apple Objective-C and JavaScript files located at

	/Developer/Library/PrivateFrameworks/XcodeEdit.framework/Versions/A/Resources
	/Developer/Applications/Xcode.app/Contents/PlugIns/TextMacros.xctxtmacro/Contents/Resources
	(some files are Copyright © 2004-2007 Apple Inc. and copyright text has been preserved)

To install the files, double click on 

	install.command
	
This will create a "~/Library/Application Support/Developer/Shared/Xcode/Specifications" directory if it does not already exist and copy the ObjectiveJ.* files to that directory. You will need to restart Xcode for the changes to take effect.
