NAME

       Cz::Sort - Czech sort

SYNOPSIS

	       use Cz::Sort;
	       my $result = czcmp("_x j&a", "_&p");
	       my @sorted = czsort qw(plachta plaoka Planieka planieka plani);
	       print "@sorted
";

DESCRIPTION

       Implements czech sorting conventions, indepentent on current locales in effect, which are often bad. Does the four-pass sort. The idea and
       the base of the conversion table comes from Petr Olsak's program csr and the code is as compliant with CSN 97 6030 as possible.

       The basic function provided by this module, is czcmp. If compares two scalars and returns the (-1, 0, 1) result. The function can be called
       directly, like

	       my $result = czcmp("_x j&a", "_&p");

       But for convenience and also because of compatibility with older versions, there is a function czsort. It works on list of strings and
       returns that list, hmm, sorted. The function is defined simply like

	       sub czsort
		       { sort { czcmp($a, $b); } @_; }

       standard use of user's function in sort. Hashes would be simply sorted

	       @sorted = sort { czcmp($hash{$a}, $hash{$b}) }
						       keys %hash;

       Both czcmp and czsort are exported into caller's namespace by default, as well as cscmp and cssort that are just aliases.

       This module comes with encoding table prepared for ISO-8859-2 (Latin-2) encoding. If your data come in different one, you might want to
       check the module Cstocs which can be used for reencoding of the list's data prior to calling czsort, or reencode this module to fit your
       needs.
