=head1 NAME

I18N::LangTags::List -- tags and names for human languages

=head1 SYNOPSIS

use I18N::LangTags::List;
  print "Parlez-vous... ", join(', ',
      I18N::LangTags::List::name('elx') || 'unknown_language',
      I18N::LangTags::List::name('ar-Kw') || 'unknown_language',
      I18N::LangTags::List::name('en') || 'unknown_language',
      I18N::LangTags::List::name('en-CA') || 'unknown_language',
    ), "?\n";

prints:

Parlez-vous... Elamite, Kuwait Arabic, English, Canadian English?

=head1 DESCRIPTION

This module provides a function 
C<I18N::LangTags::List::name( I<langtag> ) > that takes
a language tag (see L<I18N::LangTags|I18N::LangTags>)
and returns the best attempt at an English name for it, or
undef if it can't make sense of the tag.

The function I18N::LangTags::List::name(...) is not exported.

The map of tags-to-names that it uses is accessable as
%I18N::LangTags::List::Name, and it's the same as the list
that follows in this documentation, which should be useful
to you even if you don't use this module.

=head1 ABOUT LANGUAGE TAGS

Internet language tags, as defined in RFC 3066, are a formalism
for denoting human languages.  The two-letter ISO 639-1 language
codes are well known (as "en" for English), as are their forms
when qualified by a country code ("en-US").  Less well-known are the
arbitrary-length non-ISO codes (like "i-mingo"), and the 
recently (in 2001) introduced three-letter ISO-639-2 codes.

Remember these important facts:

=over

=item *

Language tags are not locale IDs.  A locale ID is written with a "_"
instead of a "-", (almost?) always matches C<m/^\w\w_\w\w\b/>, and
I<means> something different than a language tag.  A language tag
denotes a language.  A locale ID denotes a language I<as used in>
a particular place, in combination with non-linguistic
location-specific information such as what currency is used
there.  Locales I<also> often denote character set information,
as in "en_US.ISO8859-1".

=item *

Language tags are not for computer languages.

=item *

"Dialect" is not a useful term, since there is no objective
criterion for establishing when two language-forms are
dialects of eachother, or are separate languages.

=item *

Language tags are not case-sensitive.  en-US, en-us, En-Us, etc.,
are all the same tag, and denote the same language.

=item *

Not every language tag really refers to a single language.  Some
language tags refer to conditions: i-default (system-message text
in English plus maybe other languages), und (undetermined
language).  Others (notably lots of the three-letter codes) are
bibliographic tags that classify whole groups of languages, as
with cus "Cushitic (Other)" (i.e., a
language that has been classed as Cushtic, but which has no more
specific code) or the even less linguistically coherent
sai for "South American Indian (Other)".  Though useful in
bibliography, B<SUCH TAGS ARE NOT
FOR GENERAL USE>.  For further guidance, email me.

=item *

Language tags are not country codes.  In fact, they are often
distinct codes, as with language tag ja for Japanese, and
ISO 3166 country code C<.jp> for Japan.

=head1 LIST OF LANGUAGES

The first part of each item is the language tag, between
{...}.  It
is followed by an English name for the language or language-group.
Language tags that I judge to be not for general use, are bracketed.

This list is in alphabetical order by English name of the language.

=for reminder
 The name in the =item line MUST NOT have E<...>'s in it!!
