% Index generation
%
% Your TeX source contains \index{NAME} to
% signal that NAME should be included in the index.
% Check the makeindex documentation to see the various
% ways NAME can be specified, eg, for subitems, for
% explicitly specifying the alphabetization for a name
% involving TeX control sequences, etc.
%
% The first run of TeX will create \jobname.idx.
% makeindex on \jobname[.idx] will create the sorted
% index \jobname.ind.
%
% Use \inputindex (without arguments) to include this
% sorted index, typically somewhere to the end of your
% document.  This will produce the items and subitems.
% It won't produce a section heading however -- you
% will have to typeset one yourself.
%
% Use \printindex instead of \inputindex if you want
% the section heading ``Index'' automatically generated.
