%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
% dodo: autokeyexpansion => igv utf: \setupregister[index][keyexpansion=yes]
%D This module replaces existing sort key handling and is meant to be
%D used with the new texutil functionality. This module defines a few
%D auxiliary macros.

\writestatus{loading}{Context Sorting Macros (ini)}
%D The sorting method is largely bases on the one used in the old version
%D of texutil but i've changed the interface a bit. It all boils down to
%D a bunch of substitutions. The reimplementation makes it easier to extend
%D the rules. Currently we have multipass substitution and onepass sorting,
%D but we may change this some day. Since there is a plugin mechanism, using
%D an external sorter is also possible.
