			The "LINGUAS" variable is unset in your configuration,
			but the "nls" USE flag is set. Therefore, documentation for
			*all* languages will be built, which may take quite some time.
			If you want to install documentation for a defined list
			of languages, please assign "LINGUAS" accordingly.
			The following languages are supported for ${CATEGORY}/${PN}:
			"ca cs da de el en en_GB es fa fi fr hr hu it ja ko lt nl nn
			pt pt_BR ro ru sl sv uk zh_CN"
			If you want to install only the English documentation, it is
			recommended to unset the "nls" USE flag for ${CATEGORY}/${PN}.
