+% The environment |theindex| can be used for indices. It makes an
+% index with two columns, with each entry a separate paragraph. At
+% the user level the commands |\item|, |\subitem| and |\subsubitem|
+% are used to produce index entries of various levels. When a new
+% letter of the alphabet is encountered an amount of |\indexspace|
+% white space can be added.
+%
+% Override \cls{book}'s version, adding a line to the table of
+% contents.  We split out the section-creation code into
+% |\bib@heading| for \pkg{natbib} compatibility.
