It is a GEGL operation and not scriptable (as yet) as a Gimp
script-fu/python-fu
For GEGL functions you can check, as example:
http://gegl.org/operations/gegl-shadows-highlights.html
For lots of files you need (1) an up-to-date GEGL installed (2) a bash/batch
file to run the command.
You can always check the syntax of the command in Gimp. Use the "/" search +
gegl to find gegl-graph, then enter the parameters.
