  // There are basically three phases of building the production theme:
  // 1) Javascript preparation (concatenating and uglifying scripts)
  grunt.registerTask('javascript', ['concat', 'uglify']);
  // 2) Stylesheet preparation (SASS, autoprefixing, and minification)
  grunt.registerTask('styles', ['sass', 'autoprefixer', 'cssmin']);
  // 3) Appending the most recent git commit to the theme version
  grunt.registerTask('release', ['gitinfo', 'replace']);
