+# The script is used to create rescue.bin under ./arch/arm/boot/
+# Steps:
+# 1. Take rescue config and make its kernel
+# 2. Pad the zeros to kernel up to 1586688 bytes
+# 3. Cat kernel with pre-made rescue file system.
+# 4. Pad the zeros to 4-byte boundary,
+#    the resulted is rescue.bin under ./arch/arm/boot/
+#
+# arguments: "skip" : do not remake the kernel, directly do rescue.bin packing
+#
+# Qisda,Howard Hsu,2009/11/20
+# restore the original .config to avoid affect the original kernel build .config
+# input
+# this file should be executable
