-*
-* Notes on the organization of the ICU data implementation
-*
-* All of the public API is defined in udata.h
-*
-* The implementation is split into several files...
-*
-* - udata.c (this file) contains higher level code that knows about
-* the search paths for locating data, caching opened data, etc.
-*
-* - umapfile.c contains the low level platform-specific code for actually loading
-* (memory mapping, file reading, whatever) data into memory.
-*
-* - ucmndata.c deals with the tables of contents of ICU data items within
-* an ICU common format data file. The implementation includes
-* an abstract interface and support for multiple TOC formats.
-* All knowledge of any specific TOC format is encapsulated here.
-*
-* - udatamem.c has code for managing UDataMemory structs. These are little
-* descriptor objects for blocks of memory holding ICU data of
-* various types.
