+# Written by Jim Meyering.
+# Use Gnulib's robust replacement chdir function.
+# It can handle arbitrarily long directory names, which means
+# that when it is given the name of an existing directory, it
+# never fails with ENAMETOOLONG.
+#
+# It still fails with ENAMETOOLONG if the specified directory
+# name contains a component that would provoke such a failure
+# all by itself (e.g. if the component is longer than PATH_MAX
+# on systems that define PATH_MAX).
