+# Some info about Ctera firmware:
+# 1. It's simple tar file (GNU standard), but it must have ".firm" suffix.
+# 2. It contains two images: kernel and romdisk. Both are required.
+# 3. Every image has header and trailer file.
+# 4. The struct of tar firmware is: header kernel trailer header romdisk trailer
+# 5. In header file are some strings used to describe image. It was decoded from
+#    factory image.
+# 6. Version format in header file is restricted by Original FW.
+# 7. Trailer file contains MD5 sum string of header and image file.
+# 8. Firmware file must have <=24MB size.
