Changes in version 0.5:

* Corrected bug when creating ORF file from stdin.

* Added the ability to read multiple files from stdin.

* Use 'vector' instead of 'list' due to problem with gcc 3.3.1.

* Faster "processing" of images.

* Improved recognizing quality.

Be aware that frames, lines, pictures, merged chars, etc, can
(by the moment) totally confuse ocrad.
