+// Some of these targets may be moved into the recipe itself in the future.
+
+// When a NuGet package was published successfully but the corresponding symbols 
+// package failed, use this target locally after correcting the error.
+// TODO: This task is extemely complicated because it has to copy lots of code
+// from the recipe. It would be simpler if it were integrated in the recipe.
+// TODO: This has been tested on NUnit.ConsoleRunner, so the branches with either
+// zero or one packages are speculative at this point. They will need testing
+// if this is incorporated into the recipe.
