59 * The collate file format is as follows:
61 * char version[COLLATE_STR_LEN]; // must be COLLATE_VERSION
62 * collate_info_t info; // see below, includes padding
63 * collate_char_pri_t char_data[256]; // 8 bit char values
64 * collate_subst_t subst[*]; // 0 or more substitutions
65 * collate_chain_pri_t chains[*]; // 0 or more chains
66 * collate_large_pri_t large[*]; // extended char priorities
68 * Note that all structures must be 32-bit aligned, as each structure
69 * contains 32-bit member fields. The entire file is mmap'd, so its
70 * critical that alignment be observed. It is not generally safe to
71 * use any 64-bit values in the structures.
