I successfully built the tesseract.sln solution without any problem
using VS2008. The size of resultant tesseract.exe is 918KB. It runs
faster than previous versions.
I did not try the tesseract_2008.sln. Is it used in any situation? If
not, consider its removal to avoid any confusion.

The Java frontend should run on any OS that has Java 6 support. It has
been tested on Windows and Linux (Ubuntu and Fedora).
Some images would give Tesseract engine problems; it may be due to
defects in the images.

No, you would have to convert PDF to an image before feeding it to the

In 2.0x, you ought to pick the correct language to have good
