<p><code>wdiff</code> is a programs for comparing files on a word per word
basis.
It is a front-end to <code>diff</code> as found in the GNU diffutils package.
A word is anything between whitespace.  This is useful for comparing two
texts in which a few words have been changed and for which paragraphs
have been refilled.
