+    # This make invocation calls xcodebuild, which in turn performs ad hoc code
+    # signing. Note that ad hoc code signing does not need signing identities.
+    # Brew will update binaries to ensure their internal paths are usable, but
+    # modifying a code signed binary will invalidate the signature. To prevent
+    # broken signing, this build specifies the target install name up front,
+    # in which case brew doesn't perform its modifications.
