A little Clojure-like LISP in JavaScript.

1. Read about the [language essentials & documentation]!(./doc/language-essentials.md).

2. Drop wisp.min.js into your HTML code:

<script unsrc="wisp.min.js"></script>

<script type="application/wisp">
  (alert "Hello world!")
</script>

<!-- Load from a file: -->
<script type="application/wisp" unsrc="my-script.wisp"></script>

3. Or install the binary with npm:

   npm install wisp

4. Compile wisp code to native JS just like CoffeeScript:

   node_modules/.bin/wisp < my-script.wisp > my-script.js

5. Fire up a REPL to explore the language:

   ./node_modules/.bin/wisp
