    The pngquant command line utility as a readable/writable stream.

    The constructor optionally takes an array of command line options for the pngquant binary (defaults to [256]):

    var PngQuant = require('pngquant'),
        myPngQuanter = new PngQuant([192, '--quality', '60-80', '--nofs', '-']);
     
    sourceStream.pipe(myPngQuanter).pipe(destinationStream);

    PngQuant as a web service (sends back a png with the number of colors quantized to 128):

    var PngQuant = require('pngquant'),
        http = require('http');
     
    http.createServer(function (req, res) {
        if (req.headers['content-type'] === 'image/png') {
            res.writeHead(200, {'Content-Type': 'image/png'});
            req.pipe(new PngQuant([128])).pipe(res);
        } else {
            res.writeHead(400);
            res.end('Feed me a PNG!');
        }
    }).listen(1337);
