[Olena] API Doc or Code samples

Hi, I really admire Olena framework, specially Scribo module! I've been using Tesseract for a while now, and layout analysis is not it's strongest feature. Using Scribo to anaylze pictures and passing text regions to tesseract makes a lot of sense. I want to get started with using Scribo in my C++ code, however, It would be grateful if their is any kind of API docs to consult or some example programs that uses scribe API. I'd really appreciate any pointers. Keep up the excellent work! Thanks in advance. Remon
