   ***

   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.

   ***

 This module provides you with objects that will collate according to your
 national character set, provided that the POSIX sseettllooccaallee(()) 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 PPOOSSIIXX::::sseettllooccaallee(()). The basic collation conversion is
 done by ssttrrxxffrrmm(()) which terminates at NUL characters being a decent C
 routine.  ccoollllaattee__xxffrrmm(()) 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
 names are probably something like "xx_XX.(ISO)?8859-N" or
 "xx_XX.(ISO)?8859N", for example "fr_CH.ISO8859-1" is the Swiss (CH)
 variant of French (fr), ISO Latin (8859) 1 (-1) which is the Western
 European character set.
