+# subdirectory, and will verify this before proceeding.
+#
+# This script will also make a number of other verifications:
+#   . The gnulib version (it should match $GNULIB_COMMIT_SHA1).
+#   . The correct versions of the auto-tools that are used to
+#     regenerate the various scripts and Makefiles are on the PATH.
