Hello, I'm Elodie
=================
*~~ Your Personal EXIF-based Photo, Video and Audio Assistant ~~*
.. image:: ../creative/logo@300x.png
:align: center
I work tirelessly to make sure your photos are always sorted and organized so
you can focus on more important things. By photos I mean JPEG, DNG, NEF and
common video and audio files.
You don't love me yet but you will.
I only do 3 things.
- Firstly I organize your existing collection of photos.
- Second I help make it easy for all the photos you haven't taken yet to flow
into the exact location they belong.
- Third but not least I promise to do all this without a yucky proprietary
database that some friends of mine use.
You can find out more information about me on `GitHub`_.
