%   Macro to produce a table of contents line with the following
%   parameters:
%     LEVEL    : If LEVEL > \c@tocdepth, then no line produced.
%     INDENT   : Total indentation from the left margin.
%     NUMWIDTH : Width of box for number if the TITLE has a
%                \numberline command.
%                As of 25 Jan 88, this is also the amount of extra indentation
%                added to second and later lines of a multiple line entry.
%     TITLE    : Contents of entry.
%     PAGE     : Page number.
%
%  Uses the following parameters, which must be set by the document style.
%  They should be defined with \def's.
%    \@pnumwidth : Width of box in which page number is set.
%    \@tocrmarg  : Right margin indentation for all but last line of
%                  multiple-line entries.
%    \@dotsep    : Separation between dots, in mu units.  Should be \def'd to
%                  a number like 2 or 1.7
