%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D This module needs a further cleanup (real split between ii/iv).
% \cldcontext{languages.numbers[tex.count.mainlanguagenumber]}
%D This module implements multi||language support of \CONTEXT, which should not be
%D confused with the multi||lingual interface. This support will be extended when
%D needed. Properties of languages are defined in \TEX\ files as well as \LUA\
%D files.

%D When loading hyphenation patterns, \TEX\ assign a number to each loaded table,
%D starting with~0. Switching to a specific table is done by assigning the relevant
%D number to the predefined \COUNTER\ \type {\language}. However, in \MKIV\ a lot
%D of management is delegated to \LUA.
%D We keep track of the last loaded patterns by means of a pseudo \COUNTER. This
%D just one of those situations in which we don't want to spent a real one. Language
%D zero has no patterns, first of all because I like to start numbering at one. It
%D may come in handy for special purposes as well.

%D
%D Hyphenation patterns can only be loaded when the format file is prepared. The
%D next macro takes care of this loading. A language is specified with
%D
%D \showsetup{installlanguage}
%D
%D When \type {state} equals \type {start}, both patterns and additional hyphenation
%D specifications are loaded. These files are seached for in the patterns path
%D have names like \type {lang-nl.lua}.
%D
%D The \type {spacing} variable specifies how the spaces after punctuation has to be
%D handled. English is by tradition more tolerant to inter||sentence spacing than
%D other languages.
%D
%D This macro also defines \type {\identifier} as a shortcut switch to the language.
%D Furthermore the command defined as being language specific, are executed. With
%D \type {default} we can default to another language (patterns) at format
%D generation time. Patterns are loaded at runtime.
