Create a grunt template from any grunt template

// Load in required modules
module.exports = function (grunt) {
  var path = require('path');

  // Grab the keys of require.cache
  var requireCache = require.cache,
      cacheKeys = Object.getOwnPropertyNames(requireCache);

  // Find the first key that ends with grunt.js
  var i = 0,
      len = cacheKeys.length,
      cacheKey,
      gruntPath = '';
  for (; i < len; i++) {
    cacheKey = cacheKeys[i];

    // If the cacheKey ends with 'grunt.js', save it and stop searching
    if (cacheKey.slice(-8) === 'grunt.js') {
      gruntPath = cacheKey;
      break;
    }
  }

  // If there is no gruntPath, throw an error
  if (!gruntPath) {
    throw new Error('Path to grunt could not be found! =(');
  }

  // Standard path
  // var gruntPath = require.resolve('grunt'),
  var stdDir = path.join(gruntPath, '../../tasks/init');

  // Custom path (this will be null if it does not exist)
  var customDir = grunt.file.userDir('tasks/init');

  // Expose the dirs
  return {
    'grunt': gruntPath,
    'standard': stdDir,
    'custom': customDir
  };
};
