+%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 Instead of numbers,we are going to use symbolic names for the languages. The
+%D current langage is saved in the macro \type {\currentlanguage}. The setup macro
+%D is mainly used for cosmetic purposes.

+%D \macros
+%D {installlanguage}
+%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.

+%D The values \type {leftsentence} and \type {rightsentence} can be (and are) used
+%D to implement automatic subsentence boundary glyphs, like in {\fr |<|french
+%D guillemots|>|} or {\de |<|german guillemots|>|} or {\nl |<|dutch dashes|>|} like
+%D situations. Furthermore \type {leftquotation} and \type {leftquote} come into
+%D view \quotation {when we quote} or \quote {quote} something.
+
+%D \macros
+%D {currentdatespecification, currenttimespecification}
+%D
+%D Just to make things easy we can ask for the current date specification by saying:

+\def\currentdatespecification{\languageparameter\c!date}
+\def\currenttimespecification{\languageparameter\c!time}

+%D Carefull reading of these macros shows that it's legal to say
+%D

+%D \installlanguage [du] [de]
+%D \stoptyping
+
+%D \macros
+%D {language,mainlanguage}
+%D
+%D Switching to another language (actually another hyphenation pattern) is done
+%D with:
+%D
+%D \starttyping
+%D \language[identifier]
+%D \stoptyping
+%D
+%D or with \type {\identifier}. Just to be compatible with \PLAIN\ \TEX, we still
+%D support the original meaning, so
+%D
+%D \starttyping
+%D \language=1
+%D \stoptyping
+%D
+%D is a valid operation, where the relation between number and language depends on
+%D the order in installing languages.
+%D
+%D \showsetup{language}
+%D \showsetup{mainlanguage}
+%D
+%D Both commands take a predefined language identifier as argument. We can use \type
+%D {\mainlanguage[identifier]} for setting the (indeed) main language. This is the
+%D language used for translating labels like {\em figure} and {\em table}. The main
+%D language defaults to the current language.
