Hi.
Is the ALTO config option supported in the last linux version of Tesseract?
I have managed to use the HOCR but not ALTO.
Is it something I need to do with the config files?

You can use `alto` config file or use the config variable as part of command
-c tessedit_create_alto=1

Ok.
Because if a config file for alto exists (which didn`t for some reason in the install) I can just write the command with "alto" in the end, right?
Can you give me the two different commands for reading an image (with and without the confg file)?

Yes, it should be similar to hocr and you can write it at end of command.
examples:
tesseract phototest.tif - alto
tesseract phototest.tif - -c tessedit_create_alto=1
