+# Since this crate's feature setup is pretty complicated, it is worth opting
+# into a nightly unstable option to show the features that need to be enabled
+# for public API items. To do that, we set 'docsrs_regex', and when that's
+# enabled, we enable the 'doc_cfg' feature.
+#
+# To test this locally, run:
+#
+#     RUSTDOCFLAGS="--cfg docsrs_regex" cargo +nightly doc --all-features
+#
+# Note that we use `docsrs_regex` instead of the more standard `docsrs` because
+# other crates use that same `cfg` knob. And since we are enabling a nightly
+# feature, they sometimes break. By using our "own" `cfg` knob, we are closer
+# to being masters of our own destiny.
