+
+**node-environment-flags** is a *rough* polyfill and shim for [process.allowedNodeEnvironmentFlags](https://nodejs.org/api/process.html#process_process_allowednodeenvironmentflags), which was introduced in Node.js v10.10.0.

+## Install
+
+*Requires Node.js v6.0.0 or newer.*
+
+```shell
+$ npm i node-environment-flags
+```
+
+## Usage
+
+If the current Node.js version is v10.10.0 or newer, the native implementation will be provided instead.
+
+### As Polyfill (Recommended)
+
+```js
+const nodeEnvironmentFlags = require('node-environment-flags');
+
+nodeEnvironmentFlags.has('--require'); // true
+```
+
+### As Shim
+
+```js
+require('node-environment-flags/shim')();
+
+process.allowedNodeEnvironmentFlags.has('--require'); // true
+```
+
+## Notes
+
+- This module approximates what `process.allowedNodeEnvironmentFlags` provides in versions of Node.js prior to v10.10.0.  Since `process.allowedNodeEnvironmentFlags` is based on [`NODE_OPTIONS`](https://nodejs.org/api/cli.html#cli_node_options_options) (introduced in v8.0.0), the set of supported flags for versions older than v8.0.0 is *highly theoretical*.
+- Version ranges are matched using [semver](https://npm.im/semver).
+- This module is granular to the *minor* Node.js version number; *patch* version numbers are not considered.
+- Results for unmaintained (odd) versions of Node.js are based on data for the most recent LTS version; e.g., running this module against Node.js v7.10.0 will yield the same results as would v6.14.0.
+- Prior art: @ljharb's [util.promisify](https://npm.im/util.promisify)
