 I18N::LangTags::Detect - detect the user's language preferences

SSYYNNOOPPSSIISS #

   use I18N::LangTags::Detect;
   my @user_wants = I18N::LangTags::Detect::detect();

 It is a common problem to want to detect what language(s) the user would
 prefer output in.

 This module defines one public function,
 "I18N::LangTags::Detect::detect()".  This function is not exported (nor
 is even exportable), and it takes no parameters.

 In scalar context, the function returns the most preferred language tag
 (or undef if no preference was seen).

 In list context (which is usually what you want), the function returns a
 (possibly empty) list of language tags representing (best first) what
 languages the user apparently would accept output in.  You will probably
 want to pass the output of this through
 "I18N::LangTags::implicate_supers_tightly(...)" or
 "I18N::LangTags::implicate_supers(...)", like so:

   my @languages =
     I18N::LangTags::implicate_supers_tightly(
       I18N::LangTags::Detect::detect()
     );

 This module looks at several environment variables: REQUEST_METHOD,
 HTTP_ACCEPT_LANGUAGE, LANGUAGE, LC_ALL, LC_MESSAGES, and LANG.

 It will also use the Win32::Locale module, if it's installed and
 IGNORE_WIN32_LOCALE is not set to a true value in the environment.

SSEEEE AALLSSOO #

 I18N::LangTags, Win32::Locale, Locale::Maketext.

 (This module's core code started out as a routine in Locale::Maketext;
 but I moved it here once I realized it was more generally useful.)
