-/* ICU package data file format (.dat files) ------------------------------- ***
-
-Description of the data format after the usual ICU data file header
-(UDataInfo etc.).
-
-Format version 1
-
-A .dat package file contains a simple Table of Contents of item names,
-followed by the items themselves:
-
-1. ToC table
-
-uint32_t count; - number of items
-UDataOffsetTOCEntry entry[count]; - pair of uint32_t values per item:
- uint32_t nameOffset; - offset of the item name
- uint32_t dataOffset; - offset of the item data
-both are byte offsets from the beginning of the data
-
-2. item name strings
-
-All item names are stored as char * strings in one block between the ToC table
-and the data items.
-
-3. data items
-
-The data items are stored following the item names block.
-Each data item is 16-aligned.
-The data items are stored in the sorted order of their names.
-
-Therefore, the top of the name strings block is the offset of the first item,
-the length of the last item is the difference between its offset and
-the .dat file length, and the length of all previous items is the difference
-between its offset and the next one.
