Simple Node script for calling Grunt tasks without the CLI

build.js

var grunt = require('grunt')
  , args = process.argv.slice(2)
  , tasks = ['build'];

if (args && args.length){
  tasks = args;
}

grunt.cli.tasks = tasks;
grunt.cli();

save this as "build.js" in the root folder of your project (with your "gruntfile.js"). then you call call any of your tasks or aliases but doing something like:

node build cssmin

or to call multiple tasks at once:

node build less concat cssmin

the default task is "build", so calling:

node build

with no arguments will run the "build" alias. if you don't have an alias named "build", you may want to change line 5 of this script accordingly.
