Add context to a bare or mis-symbolicated iOS crash log, when symbolicate lets you down. Through scripting atos, symbology attempts to parse the crash log and resolve thread frame addresses belonging to executable, into function names.
$ node symbology.js --log ~/Desktop/Buggy.crash \
--executable ~/Library/Developer/Xcode/Archives/2014-01-21/Buggy-AppStore\ 1-21-14,\ 14.22.xcarchive/Products/Applications/Buggy.app/BuggySymbols are mined from a fixed architecture, armv7, but that will be made more flexible soon. You might consider using Crashlytics which is a Twitter-owned real-time crash reporting tool that does a very nice job symbolicating logs and just so happens to be free to boot.
