docs: To convert between different formats of the new style.
  
  <p>java opennlp.maxent.io.SuffixSensitiveGISModelReader old_model_name new_model_name
  
  <p>For example, to convert a model called "model.bin.gz" (which is thus
  saved in gzipped binary format) to one in (unzipped) text format:
  
  <p>java opennlp.maxent.io.SuffixSensitiveGISModelReader model.bin.gz model.txt
  
  <p>This particular example would of course be useful when you generally
  want to create models which take up less space (.bin.gz), but want to
  be able to inspect a few of them as plain text files.
