 * Improve logging of S3 upload failures. We should now hopefully print something
   more useful than `s3 upload error: unhandled error` on failures.
+* `Info.plist` path handling should be more robust. This should fix errors
+  like `I/O error: No such file or directory` when signing Frameworks. (#163)
