/*
* This header file describes the structures of the file format for "fat"
* architecture specific file (wrapper design). At the begining of the file
* there is one fat_header structure followed by a number of fat_arch
* structures. For each architecture in the file, specified by a pair of
* cputype and cpusubtype, the fat_header describes the file offset, file
* size and alignment in the file of the architecture specific member.
* The padded bytes in the file to place each member on it's specific alignment
* are defined to be read as zeros and can be left as "holes" if the file system
* can support them as long as they read as zeros.
*
* All structures defined here are always written and read to/from disk
* in big-endian order.
