var tmp = require('tmp');
var fs = require('fs');
var exec = require("child_process").exec;

tmp.file({postfix: ".md"}, function(err, path, fd) {
    fs.writeFile(path, "* One\n* Two", function(err) {
        if(err) return;
        exec('github-markup ' + path, function (err, stdout, stderr) {
            console.log(stdout);
            console.log(path);
