+     "Just like @code{sed} is a stream editor, @code{ted} is a token list editor.
+The @code{ted} package provides two user macros: @code{\\Substitute} and
+@code{\\ShowTokens}.  The first is maybe the most useful: it performs
+substitutions in token lists (even inside braces).  The second displays each
+token of the list (one per line) with its catcode (in the list, not just the
+current one), and can be useful for debugging or for TeX learners.  Ted is
+designed to work well even if strange tokens (that is, unusual
+@samp{@{charcode, catcode@}} pairs or tokens with a confusing meaning) occur
+in the list.")
