"Clara OCR version 0.9.9 is available. Clara OCR is designed to OCR old books. It's available under the terms of the GPL."
Clara OCR features a GUI and a web interface. It also features a
command-line interface, but X Windows is always required both to
compile and run. The development effort is using Intel 32-bits
boxes running various Linux distributions and FreeBSD."

Clara OCR was written by Ricardo Ueda Karpischek. Giulio Lunati wrote the internal preprocessor. Clara OCR includes bugfixes produced by other developers. The Changelog acknowledges all them....
