Changes in version 0.6:

* 'configure' is now compatible with 'sh', not only 'bash'.

* Better algorithmn for lowercase-uppercase decision.

* Small changes to line detector. (Less broken lines).

* Fixed bug (output of char 0 when separating some merged chars).

* Improved recognizing quality.

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