+#  In case a different version of the cbindgen utility is needed,
+#  for example, to ensure compatibility with the Firefox source code,
+#  we can install the required version of cbindgen into the cargo/bin
+#  directory before linking RcL rust-toolchain:

+#	  cargo install --version 0.26.0 cbindgen
+#
+#  and use it by defining the CBINDGEN variable in the sbin/.config file:
+#
+#	  echo "CBINDGEN := $(CARGO_HOME)/bin/cbindgen" >> $(BUILDSYSTEM)/sbin/.config
