Changes in version 0.24:

Character recognition has been improved.
(merged 'TZ' and 'rt', '9' vs 'g', 'A' vs 'R', 'C' vs '(').

Several filters can be now applied in sequence using more than one
"--filter" option.

The new filters "same_height", "upper_num" and "upper_num_only", have
been added.

The description of "OCRAD_result_blocks" in the manual has been fixed.

The license has been changed to GPL version 2 or later for better GPL
compatibility. GPLv2 and GPLv2+ programs may use the library now.
