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/share/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.
