+SUMMARY = "Nuvoton NPCM8XX bootloader"
+DESCRIPTION = "This is front end recipe for NPCM8XX IGPS. It replace \
+original IGPS recipe which need implement many redundant function in \
+recipe or class. After we add some hook in IGPS, now we can generate \
+full bootbloader by IGPS script. We only need collect all built images \
+from deploy folder, put them to IGPS input folder, and run script."
