+// This file tests the source-partitioning behavior of rustdoc.
+// Each test contains some code that should be put into the generated
+// `fn main` and some attributes should be left outside (except the first
+// one, which has no attributes).
+// If the #![recursion_limit] attribute is incorrectly left inside,
+// then the tests will fail because the macro recurses 128 times.
