  56     (description
  57      "GNU Wdiff is a front end to 'diff' for comparing files on a word per
  58 word basis.  A word is anything between whitespace.  This is useful for
  59 comparing two texts in which a few words have been changed and for which
  60 paragraphs have been refilled.  It works by creating two temporary files, one
  61 word per line, and then executes 'diff' on these files.  It collects the
  62 'diff' output and uses it to produce a nicer display of word differences
  63 between the original files.")
