option.dest output folder too

Hello,
If I have a file in a folder (for example src) in which I test and develop my package, and I define a folder (for example dist) in which all beautified pages must go, it will copy the folder too (dist/src/files).
Please, fix this.

These are the options I used:

jsbeautifier: { files: ['src/development.js'], options: { dest: 'dist', } }

It would be really nice if I can chose the filename to output maybe like in grunt-uglify:

build: { src: 'src/development.js', dest: '<%= pkg.name %>.min.js' }
