Want a freeware small OCR software (batch processing capable)

Hi All! I want a freeware small OCR software which can transform text in many pictures and saveit in a text file. If you happen to know some s/w meeting these requirements, please give me links. Please note that I don't need a s/w which selects text from a single image and save it into a text file, but one that can select text from many pics(i.e. supporting batch processing) and then saving all the text in a single text file.

Thanks in advance.
