title: How to find parameters supported in Tesseract OCR config file
body: <p>I want to know what parameters the config file used by Tesseract OCR accepts, how to write a config file, etc.</p>
  
  <p>I can't find any documentation about this on <a href="https://code.google.com/p/tesseract-ocr/" rel="noreferrer">their site</a>. How can I determine what parameters are supported, and what they mean?</p>
