I found this thread to be interesting since I tried training Tesseract a
few years ago and gave up. Has anybody considered writing any
documentation on this something that is best explained whenever a user
can't figure it out from trial/error? I'm open to maybe writing about this
if there is a need for it, but first, I will have to understand it better
myself.
