NAME
          sq - squeeze a sorted word list unsq - unsqueeze a sorted
          word list

     SYNOPSIS
          sq < infile > outfile

          unsq < infile > outfile

     DESCRIPTION
          sq compresses a sorted list of words (a dictionary). For
          example:
               sort /usr/dict/words | sq | compress > words.sq.Z
          will compress dict by about a factor of 4.

          unsq uncompress the output of sq. For example:
               compress -d < words.sq.Z | unsq | sort -f -o words
          will uncompress a dictionary compressed with sq.

          The squeezing is achieved by eliminating common prefixes,
          and replacing them with a single character which encodes the
          number of characters shared with the preceding word.  The
          prefix size is encoded as a single printable character:  0-9
          represent 0-9, A-Z represent 10-35, and a-z represent 36-61.
