doc() {
	# Man pages
	mkdir -p "$subpkgdir"/usr/share/man || return 1
	mv "$pkgdir"/usr/share/man/man* "$subpkgdir"/usr/share/man/ \
		|| return 1

	# Doc files
	_docs="CODING_STANDARDS CREDITS EXTENSIONS INSTALL LICENSE NEWS \
	README.EXTENSIONS README.EXT_SKEL README.MAILINGLIST_RULES \
	TODO-PHP5 UPGRADING UPGRADING.INTERNALS"
	for _doc in $_docs; do
		install -Dm644 "$srcdir"/$pkgname-$pkgver/$_doc \
			"$subpkgdir"/usr/share/doc/$pkgname/$_doc || return 1
	done
