I installed python - pycairo - pygobject and pygtk then I installed GIMP.
I go to Filters > Python-fu and I see Console.
According to the directions at: http://registry.gimp.org/node/25395
I should be able install these ebook plugins. I placed the .py files in the "lib > gimp > 2.0 > python" folder.
But when I restart GIMP and go to Filters, I don't see Ebook anywhere.
