 %description
-`wdiff' is a front-end to GNU `diff'.  It compares two files, finding
-which words have been deleted or added to the first in order to create
-the second.  It has many output formats and interacts well with
-terminals and pagers (notably with `less').  `wdiff' is particularly
-useful when two texts differ only by a few words and paragraphs have
-been refilled.
+The GNU wdiff program is a front end to diff for comparing files on a word per
+word basis. 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. It works by creating two temporary files, one word per line, and
+then executes diff on these files. It collects the diff output and uses it to
+produce a nicer display of word differences between the original files.
