+
+DESCRIPTION
+<<setlocale>> is the facility defined by ANSI C to condition the
+execution environment for international collating and formatting
+information; <<localeconv>> reports on the settings of the current
+locale.
+
+This is a minimal implementation, supporting only the required <<``C''>>
+value for <[locale]>; strings representing other locales are not
+honored unless MB_CAPABLE is defined in which case three new
+extensions are allowed for LC_CTYPE only: <<''C-JIS''>>, <<''C-EUCJP''>>,
+and <<''C-SJIS''>>.  (<<``''>> is also accepted; it represents the default locale
+for an implementation, here equivalent to <<``C''>>.)
+
+If you use <<NULL>> as the <[locale]> argument, <<setlocale>> returns
+a pointer to the string representing the current locale (always
+<<``C''>> in this implementation).  The acceptable values for
+<[category]> are defined in `<<locale.h>>' as macros beginning with
+<<"LC_">>, but this implementation does not check the values you pass
+in the <[category]> argument.
+
+<<localeconv>> returns a pointer to a structure (also defined in
+`<<locale.h>>') describing the locale-specific conventions currently
+in effect.  
+
+<<_localeconv_r>> and <<_setlocale_r>> are reentrant versions of
+<<localeconv>> and <<setlocale>> respectively.  The extra argument
+<[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+<<setlocale>> returns either a pointer to a string naming the locale
+currently in effect (always <<``C''>> for this implementation, or, if
+the locale request cannot be honored, <<NULL>>.
+
+<<localeconv>> returns a pointer to a structure of type <<lconv>>,
+which describes the formatting and collating conventions in effect (in
+this implementation, always those of the C locale).
+
+PORTABILITY
+ANSI C requires <<setlocale>>, but the only locale required across all
+implementations is the C locale.
+
+No supporting OS subroutines are required.
