; NAME: RBSP_LOAD_SPICE_PREDICT
;
; SYNTAX:
;   rbsp_load_spice_predict
;   rbsp_load_spice_predict,/unload
;
; PURPOSE:  Loads/unloads the most recent RBSP SPICE predicted attitude and
;			ephemeris kernels found in local RBSP data directories:
;				$LOCAL_DATA_DIR/MOC_data_products/RBSP?/*_predict/
;			Predicted attitude files are retrieved from the remote data
;			server if available.
;
; KEYWORDS:
;	/all - loads all predict kernels, rather than only the most recent
;	/unload - unloads kernel files
;	/no_download - skips automatic download
;
; NOTES:
;	Access to RBSP predicted ephemeris kernels is restricted.  The
;	$LOCAL_DATA_DIR/MOC_data_products/RBSP?/ephemeris_predict/ directories must
;	be populated manually.
