+% The option multind provides support for several indexes with pagerefs,
+% albeit with a simple layout. There is just one index file,
+% and the usual compilation cycle (latex, makeindex, latex) suffices.
+% With the command \setindex in the LaTeX file one arranges which index is
+% the active one at any given moment.
+% This steers the behaviour of \index and \printindex.

+% That is the positive part.

+% While robustindex.sty broke the automatic page range feature of
+% makeindex, the multind option also breaks the insertions
+% of \indexspace in the index file.
+% This makes that the layout of an index gets more plain.
+% The various hacks make the index file pretty unreadable
+% and style files of makeindex will probably fail.

% The package imakeidx also synchronises the index with the manuscript,
