- * UCommonData An abstract interface for dealing with ICU Common Data Files.
- * ICU Common Data Files are a grouping of a number of individual
- * data items (resources, converters, tables, anything) into a
- * single file or dll. The combined format includes a table of
- * contents for locating the individual items by name.
- *
- * Two formats for the table of contents are supported, which is
- * why there is an abstract inteface involved.
- *
- * These functions are part of the ICU internal implementation, and
- * are not inteded to be used directly by applications.
