NAME
       prep - prepare text for statistical processing

SYNOPSIS
       prep [ -diop ] file ...

DESCRIPTION
       Prep  reads  each file in sequence and writes it on the standard output, one `word' to a line.  A word is a string of alphabetic characters
       and imbedded apostrophes, delimited by space or punctuation.  Hyphented words are broken apart; hyphens at the end of lines are removed and
       the hyphenated parts are joined.  Strings of digits are discarded.

       The following option letters may appear in any order:

       -d     Print the word number (in the input stream) with each word.

       -i     Take  the  next file as an `ignore' file.  These words will not appear in the output.  (They will be counted, for purposes of the -d
	      count.)

       -o     Take the next file as an `only' file.  Only these words will appear in the output.  (All other words will also be counted for the -d
	      count.)

       -p     Include  punctuation  marks (single nonalphanumeric characters) as separate output lines.  The punctuation marks are not counted for
	      the -d count.

       Ignore and only files contain words, one per line.
