+wdiff (display word differences between text files)
+
+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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
