                search: '(^|\\s)console.log',
                replace: '//console.log',
                flags: 'g'
            },{
                name: 'foo',
                search: 'var v = \'[^\']*\';',
                replace: 'var v = \'<%= pkg.release.version_code %>\';',
                flags: ''
            },{
               name: 'foobar',
               search: new RegExp('\\w+'),
               replace: function(){
                       return 'foofoo';
               }
            }
        ]
    }

  src: '**/*.js',
  src: ['foo/bar.js','foo/foo.js'],
  src: ['<%= pkg.id %>/bar.js', 'foo/foo.js']

actions property ()

Accepts an array of objects representing the actions to take place. Each action contains an optional name property, a search property, a replace property and a flags property. Example af an object.

  {
      name: 'foo',
    search: '(^|\\s)console.log',
    replace: '//console.log',
    flags: 'gi'
  }

  {
    name: 'bar',
    search: /\\w+/g, //also accepts new RegExp()
    replace: function(){
        return 'foo';
    }
  }

name property

A string value

search property (regexp | substr)

A regular expression string or object defining the text content to be found.

replace property (substr | function)
