+# NODE_MODULE_VERSION refers to the ABI (application binary interface) version
+# number of Node.js, used to determine which versions of Node.js compiled C++
+# add-on binaries can be loaded in to without needing to be re-compiled. It
+# used to be stored as hex value in earlier versions, but is now represented as
+# an integer.
