var gulp  = require('gulp');  // https://www.npmjs.com/package/gulp
var plato = require('plato'); // https://www.npmjs.com/package/plato
var open  = require('open');  // https://www.npmjs.com/package/open

// Override defaults by setting node environment variables: $ SRC='./js/**/*.*' DEST='./info' gulp report
var src  = process.env.SRC  || './src/**/*.*';
var dest = process.env.DEST || './report';

gulp.task('report', function() {
    plato.inspect(src, dest, {}, callback);

    function callback(report) {
