###### USING AN EXTERNAL DATA FILE FOR METADATA (TITLE, DESCRIPTION, KEYWORDS)
### Since IPTC data is a bit old fashioned I implemented a way to store the metadata
### in an external text file.
### This uses a .dat file named like this:
### If the image name is "2001_23.jpg",
### the datfile name is "2001_23.jpg.dat"
###
### The Datfile may have up three lines:
### Line 1: Title
### Line 2: Description
### Line 3: Keywords
###
### Example:
### -------file-------
### Portrait Of Foo's Mother
### Oil on drywall, 2015
### painting grafitti
### ------------------
