Thanks for the reply. I believe that I need to contact the wrapper
developer Lois Di Qual. It is using the tesseract 3.0.2 release. My
interpretation is that the appears that the wraper does not use a configs
file. The wrapper has a setVariableValue method that I coded as follows:
[tesseract setVariableValue:@"TRUE" forKey:@"tessedit_create_hocr"];
It doesn't generate the html output.
