Build and deploy tools for Cocoa apps using Sparkle for distributions and upgrades; it's like Hoe but for Cocoa apps. The main feature is a powerful rake task "rake appcast" which builds a release of your application, creates a DMG package, generates a Sparkle XML file, and posts the package and XML file to your remote host via rsync. All rake tasks: rake appcast # Create dmg, update appcast file, and upload to host rake build # Build Xcode Release rake dmg # Create the dmg file for appcasting rake feed # Create/update the appcast file rake upload # Upload the appcast file to the host
