+# sigint-hook
+Normalize the process SIGINT signal.
+
+## Usage
+
+### Install
+```
+npm install sigint-hook
+```
+
+### Configuration
+`eventOnHookOnly` (default `false`): if `true`, will not emit on the `process` global object
+`triggerOnce` (default: `false`): if `true`, will stop listening after first `SIGINT` signal
+
+### Examples
+Default:
+```js
+require("sigint-hook")().on("SIGINT", function() {
+  // do something
+});
+```
+Customized:
+```js
+require("sigint-hook")({
+	eventOnHookOnly: true,
+	triggerOnce: true
+}).on("SIGINT", function() {
+  // do something
+});
+```
+Please note that you can kill sigint-hook by running the `.close()` method on the return object:
+```js
+var sigint = require("sigint-hook")({
+	eventOnHookOnly: true
+}).on("SIGINT", function() {
+  // do something
+});
+
+// kill off early:
+sigint.close();
+```
