-object-to-spawn-args
-====================
+#object-to-spawn-args
+Converts an options object to an array suitable for passing to `child_process.spawn()`. 
+
+Single letter object properties (e.g. `c: "red"`) convert to short-option args (e.g. `-c red`). Longer object properties (e.g. `colour: "red"`) convert to long-option args (e.g. `--colour red`). Object property values equalling `true` convert to flags (e.g. `-l`).
+
+This options object:
+```js
+var options = {
+    l: true,
+    c: "red",
+    man: "pete",
+    tramp: true
+}
+```
+
+converts to 
+```js
+[ "-l", "-c", "red", "--man", "pete", "--tramp" ]
+```
+
+##Installation
+Move into your project directory then run: 
+```sh
+$ npm install object-to-spawn-args --save
+```
+*Mac / Linux users may need to run with `sudo`*.
+
+
+##Usage
+```js
+var toSpawnArgs = require("object-to-spawn-args");
+var spawn = require("child_process").spawn;
+
+var options = {
+    l: true,
+    a: true
+};
+
+spawn("ls", toSpawnArgs(options), { stdio: "inherit" });
+```
