  In general, you would build a dictionary, look up for every word in
the input whether it is in the dictionary, and if not, which is the
most similar word using some string metric.

  You will, however, face problems:

  - No dictionary is ever complete
  - Some wrong words are equally similar to multiple correct words
(e.g. should "bt" be "bit" or "but" or "bat"?)
  - Not all errors lead to wrong words (e.g. "Sum errors will will nut
bee fond because they happen to leed two sentence consisting of reel
word")

  It is therefore doubtful that spell-correction can be done non-interactively.

     Take care
     Oliver
