What can I use for OCR?

What can I use for OCR? I have tried gocr, which seems usable. Also clara, which seems horrible to me: only accepts files in pbm format, and so far produced nothing: It's been working on another window for 15 minutes or more, 90% CPU of a pentium IV, and no text output so far. Aparently, I have got to "train it", but it took 5 minutes to learn the letter "A", having to wait for it to reddraw after each click for minutes. There is something very wrong there... I hate to say this, but a friend demonstrated to me his Ms-word scanning a page, and it almost even got the format (typesetting) correct! I can't believe clara or gocr is the best I can find in linux, there must be something better :-? -- Cheers, Carlos Robinson
