+# This is a script that can be used in each book's CI to validate links using
+# the same tool as rust-lang/rust.
+#
+# This requires the rust-docs rustup component to be installed in the nightly
+# toolchain.
+#
+# Usage:
+#   ./linkcheck.sh <name-of-book>
+#
+# Options:
+#
+# -i        "Iterative" mode. The script will not clean up after it is done so
+#           you can inspect the result, and re-run more quickly.
+#
+# --all     Check all books. This can help make sure you don't break links
+#           from other books into your book.
