+The user will typically involve little more than is printed, and will still
+get LaTeX quality.The bundle provides four packages:
+
+@itemize
+
+@item @code{wiki} addresses general texts, marked up in the simple style used
+on Wikipedia;
+
+@item @code{niceverb} is yet another means of documenting LaTeX packages: it
+offers syntax-aware typesetting of meta-variables (macro arguments) and for
+referring to commands (and their syntax) in footnotes, section titles etc.;
+
+@item @code{fifinddo} aims to parse plain text or (La)TeX files using TeX, and
+to write the results to an external file;
+
+@item @code{makedoc} provides the means to produce typeset documentation
+direct from package files.
