+config BR2_PACKAGE_MAEMO_LIBCAL
+	bool "maemo-libcal"
+	help
+	  Maemo devices (such as the Nokia N900) have a "calibration" storage
+	  area where various bits of configuration data are kept.  CAL is a
+	  Maemo-specific C API for reading and writing this data.
+
+	  This package installs a free-software reimplementation of this API
+	  from the Community SSU project
+	  (<https://github.com/community-ssu/libcal>)
+
+	  (This is a RescueOS-specific package inserted by patching; see
+	   N900_RescueOS/buildroot-patches/pkg-maemo-libcal.patch)
