+# This script must be run from the root of the Nix repository.
+#
+# For include path hygiene, we need to put headers in a separate
+# directory than sources. But during development, it is nice to paths
+# that are similar for headers and source files, e.g.
+# `foo/bar/baz.{cc,hh}`, e.g. for less typing when opening one file, and
+# then opening the other file.
+#
+# This script symlinks the headers next to the source files to
+# facilitate such a development workflows. It also updates
+# `.git/info/exclude` so that the symlinks are not accidentally committed
+# by mistake.
