I just wanted to ask for your attention for my open source project to replace genstrings: http://www.cocoanetics.com/2012/01/genstrings2/
The first immediate advantage for you is that this no longer crashes on parsing problems like the original, but just ignores that problematic Macro use and scans on.
I am looking for somebody to test genstrings2 versus genstrings on a sizeable project with much source code and time it for comparison.
Cheers
