                     12: typo  proofreads an  English-language document  for typographical
                     13: errors.   It conducts  a statistical test  of letter  digrams and

                     15: cies throughout  the entire document.  From  this test, typo com-
                     16: putes an  index of peculiarity for each word  in the document.  A
                     17: high index indicates a word less like other words in the document
                     18: than does a  low index.  Built-in frequency tables ensure reason-
                     19: able results even for relatively short documents.

                     21: typo reads  each input file (or the standard  input if none), and
                     22: removes  punctuation and non-alphabetic  characters to  produce a
                     23: list of the  words in the document.  To reduce  the volume of the
                     24: output,  typo compares  each word against  a small  dictionary of
                     25: technical words and discards it if found.  The output consists of
                     26: a list  of unique non-dictionary  words with associated  index of
                     27: peculiarity, most  peculiar first.  An index  higher than ten in-
                     28: dicates that  the word almost  certainly occurs only  once in the
                     29: document.

                     35:      words will be output  and the indices of peculiarity will be
                     36:      less useful for short documents.
                     37:

                     39:      Normally, typo  strips lines beginning with  `.' and removes
                     40:      the nroff escape sequences `\'.
