Grunt copies all JS files

[Waqass]

Hi, I'm new to bower and grunt thing so need a little clarification here. Why does grunt copies all the filed in JS folder when using grunt build. The following task copies everything from bower components folder and maps folder. Where as per my understanding only three files are required to run theme successfuly 1. Jquery, 2.Modernizer 3. App.js which included custom script and foundation js.Shouldn't be this folder clean with only these three files. Last but not least why doesn't all these three filed have been concatenated to App.js.

copy: {
  scripts: {
    expand: true,
    cwd: 'bower_components/',
    src: '**/*.js',
    dest: 'js'
  },

  maps: {
    expand: true,
    cwd: 'bower_components/',
    src: '**/*.map',
    dest: 'js'
  }
},

Hi,
Please see the documentation for answers to your questions. Feel free to change the Grunt file so that it coincides with your requirements and needs.

I have worked a little further with FoundationPress tonight. Have changed the way you load scripts and files and made some improvements in Gruntfile.js. Have also updated the docs. Hopefully it's a little clearer now.

yup you have cleared up much of the clutter and files are now in a much more organized way. A major overhaul perhaps. Kudos on that!
Just one last question the vendor folder has fastclick.js and placeholder.js which haven't been employed anywhere in the theme. Are they for to be manually integrated or am I missing something?
