Narwhal Quick Start
===================
Download Narwhal.
* download and extract the [zip](http://github.com/tlrobinson/narwhal/zipball/master) or [tar](http://github.com/tlrobinson/narwhal/tarball/master) archive, or
* `git clone git://github.com/tlrobinson/narwhal.git`
Put Narwhal on your PATH environment variable.
* `export PATH=$PATH:~/narwhal/bin`, or
* execute `narwhal/bin/sea` for a quick Narwhal subshell
Run `narwhal` or `js` (they're equivalent).
* `js narwhal/examples/hello`
Look at the options.
* `narwhal --help`
* `tusk help`
My First Web Server
===================
Create a project "hello-web".
tusk init hello-web
cd hello-web
Enter your project as a "virtual environment" using `sea` so that its libraries, binaries, and packages get automatically installed when you run Narwhal.
bin/sea
Install some packages you will need, like Jack, the JSGI standard library for interoperable web services.
tusk install jack
Tusk gets downloaded and installed at "hello-web/packages/jack".
Create your "jackconfig.js". This is a trivial JSGI compatible application, wrapped in the `ContentLength` middleware to automatically set the "Content-Length" header.
var jack = require("jack");
exports.app = jack.ContentLength(function (env) {
return [200, {"Content-type": "text/plain"}, ["Hello, Web!"]];
});
Run it!
jackup
Next, take a look at the introduction to [modules](modules.html), for a primer on using and making modules in Narwhal.
