+     "The @code{tocdata} package may be used to add a small amount of data to an
+entry in the table of contents or list of figures, between the section or
+caption name and the page number.  The typical use would be to add the name of
+an author or artist of a chapter or section, such as in an anthology or
+a collection of papers.  Additionally, user-level macros are provided which
+add the author's name to a chapter or section, along with an optional prefix
+and/or suffix, and add to a figure the artist's name, prefix, and suffix, plus
+optional additional text.  Author and artist names are also added to the
+index.  Additional user-level macros control formatting.  @code{tocdata} works
+with the TOC/LOF formatting of the default LaTeX classes, @code{memoir},
+@code{koma-script}, and with @code{titletoc}, @code{tocloft}, @code{tocbasic},
+and @code{tocstyle}.")
