Cleansing photo folder

Introduction

After several years of shooting photos everydays with several devices, my photo repository is getting messy:

some have been copied accross directories
some copied,with a different names
some distinct photo have same name
unconsistent folder naming I wrote this utility in order to have a simple but proven folder organisation : YEAR\YEAR.MONTH\YEAR.MONTH.DAY hierarchy based on taken date available in exif metadata when available.

The utility scans the given folder. For each photo, it checks the path where it should be located. When it differs from the actual path, it moves it.

At the end of the process, empty folders are removed.

Usage

Flags:
      --help                     Show context-sensitive help (also try

                                 model for path
