%NAME: citesort.sty
|
|
% A replacement for \@citex which sorts citation numbers as well as
|
|
% compressing and allowing breaks. Based on cite.sty by Donald
|
|
% Arseneau.
|
|
%
|
|
% for use in LaTeX say, \documentstyle[...,citesort,...]{...}
|
|
%
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
% Allow, but strongly discourage, line breaks within a long
|
|
% series of citations. Compress lists of successive numbers
|
|
% to one number range, e.g., 5,6,7,8,9 --> 5--9. Compatible
|
|
% with versions of \@cite that use exponents.
|
|
% -- Donald Arseneau 1989
|
|
%
|
|
% Modified to sort the numbers so they come out in increasing order,
|
|
% regardless of the way they appear in the source. O(N^2) sort!
|
|
% Ian Green, CUED, 10-Dec-1991. Improvements to img@eng.cam.ac.uk
