Motivation
The reason for creating this utility was to help organise the pictures I
take. For years I have organised my pictures on my home computer under ~/pics/YYYY/mm/dd to facilitate finding them.
I started taking pictures before excellent programmes like Darktable were available
that create databases of pictures and use the metadata of creation dates to allow browsing.
Even though I use such tools now I still prefer organising my pictures in this manner because it just makes sense to me, its logical, simple and doesn't rely on external tools.
