 % Fix the index environment to add an entry to the Table of
 % Contents; this is much nicer than just having to jump to the end of the book
 % and flip around, especially with multiple indexes.
+% The memoir class already does this, so we don't duplicate it in that case.
 %
 % A similiar fix must be done to the bibliography environment, although
 % dependant on document class. In particular, the '\addcontentsline' command
 % should use 'chapter' for a report and 'section' for an article.
 % See sphinxmanual.cls and sphinxhowto.cls for specific fixes.
