%  Generic indexing macros
%
% The following 14 commands are generic commands for producing main items,
% subitems, and subsubitems in the index.  For each of these three types of 
% entries, there are four kinds of commands:
%
% 1. produce a single page number entry
% 2. begin an entry with a range of pages associated with it
% 3. end an entry with a range of pages associated with it
% 4. produce a definition entry (single page number in bold face type)
%
% There are also 2 commands, one for subitems and one for subsubitems,
%  for producing "see also <text>" entries 
%
% Each of these commands requires some number of arguments which supply
% the text to be used in indexing.  Main item commands require 1 argument; 
% subitem commands require 2 arguments (main item and subitem text); 
% subsubitem commands require 3 arguments (main item, subitem, and subsubitem
% text).  
%
% All 14 commands have an optional argument, which is the category of
% the main item being indexed.  The valid values for this category argument 
% are:
%      C -- for class or other C++ name 
%      c -- for concept 
%      d -- for data structure
%      f -- for functionality
%      h -- for hint
%      l -- for library
%      p -- for package
%      t -- for term
% The default value of this argument is empty, indicating an entry that
% does not fall into any of the established categories for the index.
% Depending on the category specified, the appropriate font will be used
% to format the main item text.  Fonts can also be supplied in the
% text arguments and these fonts override any font indicated by the
% category argument.
