		<description>
			<para>Polish grammar has some funny rules for counting words. for example 1 zloty,
			2 zlote, 5 zlotych. This application will take the words for 1, 2-4 and 5 and
			decide based on grammar rules which one to use with the number you pass to it.</para>
			<para>Example: SayCountPL(zloty,zlote,zlotych,122) will give: zlote</para>
