Attached are a shell script to illustrated use of ckformat as well as a copy of the C source generated from ImageFormat.
Happy New Year!

==================== Summary ====================
Name: ImageFormat-dtl.7 Author: dtl Time: 31 December 2010, 6:40:20 am UUID: a8499caf-2b80-4c5c-82e7-e2b10455f42a Ancestors: ImageFormat-dtl.6
Generate ckformat.c, a utility program for reading the image file format number from an image file. The ckformat program is intended for testing image file format from a unix shell script such that the shell script can select a VM based on image requirements. A non-zero return status code from ckformat indicates failure, otherwise the format number is written to standard output with no line terminator. The utility handles big-endian and little-endian versions of all known 32 and 64 bit image formats.
The ckformat C code is generated from ImageFormat to ensure that it is updated as new format numbers are assigned and documented in class ImageFormat.
