current locale
***
WARNING: starting from the Perl version 5.003_06
the I18N::Collate interface for comparing 8-bit scalar data
according to the current locale
HAS BEEN DEPRECATED
That is, please do not use it anymore for any new applications
and please migrate the old applications away from it because its
functionality was integrated into the Perl core language in the
release 5.003_06.
See the perllocale manual page for further information.

SYNOPSIS
use I18N::Collate;
setlocale(LC_COLLATE, 'locale-of-your-choice');
$s1 = new I18N::Collate "scalar_data_1";
$s2 = new I18N::Collate "scalar_data_2";
DESCRIPTION
This module provides you with objects that will collate
according to your national character set, provided that
the POSIX setlocale() function is supported on your
system.
You can compare $s1 and $s2 above with
$s1 le $s2
to extract the data itself, you'll need a dereference:
$$s1
This module uses POSIX::setlocale(). The basic collation
conversion is done by strxfrm() which terminates at NUL
characters being a decent C routine. collate_xfrm()
handles embedded NUL characters gracefully.
The available locales depend on your operating system; try
whether locale -a shows them or man pages for "locale" or
"nlsinfo" or the direct approach ls /usr/lib/nls/loc or ls
/usr/lib/nls or ls /usr/lib/locale. Not all the locales
that your vendor supports are necessarily installed:
please consult your operating system's documentation and
possibly your local system administration. The locale
