Going Public

• Load and parse Xcode Projects and Workspaces.
• Save Xcode Projects and Workspaces. Saving an unmodified input project should result in no actual changes!
• Perform some basic operations on a project, such as:
  • Sorting a group (recursively if desired)
  • Adding new groups, removing groups, adding new files, adding files to a build phase
  • Perform a sync operation on a group (recursively). This will add any files on the filesystem to the group and remove files no longer on the filesystem from the group
• And much much more! (probably)
