+
+
+### Bug Fixes
+
+* get our test suite running on Windows ([#23](https://github.com/tapjs/signal-exit/issues/23)) ([6f3eda8](https://github.com/tapjs/signal-exit/commit/6f3eda8))
+* hooking SIGPROF was interfering with profilers see [#21](https://github.com/tapjs/signal-exit/issues/21) ([#24](https://github.com/tapjs/signal-exit/issues/24)) ([1248a4c](https://github.com/tapjs/signal-exit/commit/1248a4c))

+
+When you want to fire an event no matter how a process exits:
+
+* reaching the end of execution.
+* explicitly having `process.exit(code)` called.
+* having `process.kill(pid, sig)` called.
+* receiving a fatal signal from outside the process
+
+Use `signal-exit`.
+
+```js
+var onExit = require('signal-exit')
+
+onExit(function (code, signal) {
+  console.log('process exited!')
+})
+```
+
+## API
+
+`var remove = onExit(function (code, signal) {}, options)`
+
+The return value of the function is a function that will remove the
+handler.
+
+Note that the function *only* fires for signals if the signal would
+cause the proces to exit.  That is, there are no other listeners, and
+it is a fatal signal.
+
+## Options
+
+* `alwaysLast`: Run this handler after any other signal or exit
+  handlers.  This causes `process.emit` to be monkeypatched.
