Announcing the OCRopus Open Source OCR System April 9, 2007 and remark in old CHANGES: "The Ocropus svn was opened to the public in April 2007 in order to give a first preview of the project. The Technology Preview internally combined Tesseract 1.x with some Layout Analysis algorithms.In this stage, a basic system was already working but the whole architecture was still changing as well as the interfaces for the respective modules / components."
