+JsonConfigReader is a proxy for [golang's io.Reader](http://golang.org/pkg/io/#Reader) that strips line comments and trailing commas, allowing you to use json as a *reasonable* config format.
+
+Comments start with `//` and continue to the end of the line.
+
+If a trailing comma is in front of `]` or `}` it will be stripped as well.
+
+
+Given `settings.json`
+
+	{
+		"key": "value", // k:v
+		
+		// a list of numbers
+		"list": [1, 2, 3],
+	}
+
+
+You can read it in as a *normal* json file:
+
+	package main
+
+	import (
+		"encoding/json"
+		"fmt"
+		"github.com/DisposaBoy/JsonConfigReader"
+		"os"
+	)
+
+	func main() {
+		var v interface{}
+		f, _ := os.Open("settings.json")
+		// wrap our reader before passing it to the json decoder
+		r := JsonConfigReader.New(f)
+		json.NewDecoder(r).Decode(&v)
+		fmt.Println(v)
+	}
