i think the contents of these little saved files would just be the
values that you selected in the dialog.  did you try to look at them
with a text editor?  if matlab can accept a value for "gamma" then i
think it should probably be in this little file.

i used gimp-gap to do this.  gimp-gap will work on sequentially named
files.  you can have a preview look at the tutorial that is officially
online when gimp-2.2pre (or whatever) is released:
http://carol.gimp.org/gimp/2.1/gap/layers/ shows some of the dialogs you
will need to look into.  an epic/horror story about when i used an
earlier combination of this plug-in and some of its supporting software
can be seen here:
"Give GAP a curve" is where i did successfully apply the same curve to a
bunch of images.

There is also the option to script it.  some scripting experience is
probably helpful for that though.
