	Introduction
		The =Uize.Build.PluralsModules= build script builds plural rules modules for various languages, as defined by the [[http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html][CLDR plural rules]].

		*DEVELOPERS:* `Chris van Rensburg`

		EXAMPLE
		..........................................................................................
		node build.js Uize.Build.PluralsModules pluralRules=../cldr/json/supplemental/plurals.json
