        output of not defined chars (HTML="&#xxx;", TeX="\symbol{xxx}")
        system dependend bug: isupper(>255) SIGSEGV fixed
        better line detection for lines with lowercase chars only
        lot of possible SIGSEGV in list_del() fixed
        barcode recognition (UPC,code128)
        .ps .eps via pstopnm supported
        -m 256 switches off the main ocr engine (usefull together with -m 2 for identical chars)

 0.3.5
        minor and major fixes (string\0 bugs)
        memory leak fixes by Duncan Edwards
        layout analysis or zoning (-m 4) improved, 
        now it detects pictures and columns much better
        the behavior of setting threshold (-l) is slightly changed
        wcsdup defined for non-gnu-systems (BSD), further Problems?
        better context correction for 10 (IO,lO)
        Fixes for S.Koledin examples "GlS"
        Euro-currency-sign detection added
        better pitch estimation for proportional font (needs to be improved)
        make install DESTDIR= instead configure --prefix= (better?)
        use wchar_t by default, more simple code and -f works with nonLinuxOS
        line detection more robust against vertical glued chars (js)
        -f UTF8 added (usefull for xterm -u8), should be default?
        handle vertical glued boxes (ex: g over T)
 0.3.4
        some BSD adaptions (no WCHAR?), tell me if there are still problems
        use unicode in database (4-8 hex digits)
        new option: -p database_path/

        layout analysis improved
 0.3.3
        database (-m 2) bug fixed and interactive mode (-m 130) added
          its not finished, but you can test it
          result should be ok for machine generated images (no scans)

 0.2.6  pipes used on POSIX2-systems for easier use of jpg,gif,tiff,pnm.gz-files
        example: gocr text.jpg; gocr text.pnm.gz
        verbose output on stderr, text output on stdout,
        redirection of output possible (-e, -o, example: -e /dev/stdout)
