//   sidebar ItemName sbBj - to set specific item icon, see:
//                           /System/Library/CoreServices/CoreTypes.bundle/Contents/Info.plist
// Compile it with:
//   gcc -o sidebar sidebar.m -F /Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/CoreServices.framework/Frameworks -framework Foundation -framework CoreServices
//
// Some interesting IDs:
//   com.apple.LSSharedFileList.SpecialItemIdentifier
//   com.apple.LSSharedFileList.TemplateSystemSelector

Hallelujah... After searching for a solution for whole f****** day your little app solved my problem with sidebar icons. You are a genius man. Thank you thousand times...

Thanks for sharing, this helped tremendously in writing https://github.com/Aeon/sidebarFinagler

I am on ML 10.8.3 and compiled this but, I'm not seeing anything update on the sidebar I got it to run without an error but none of the icons are updating even after I 'killall Finder'

running it like: ./sidebar Video sbDl
