  * \brief C API: Resource Bundle 

  *

  * <h2>C API: Resource Bundle</h2>

  *

  * C API representing a collection of resource information pertaining to a given

  * locale. A resource bundle provides a way of accessing locale- specific information in

  * a data file. You create a resource bundle that manages the resources for a given

  * locale and then ask it for individual resources.

  * <P>

  * Resource bundles in ICU4C are currently defined using text files which conform to the following

  * <a href="http://dev.icu-project.org/cgi-bin/viewcvs.cgi/~checkout~/icuhtml/design/bnf_rb.txt">BNF definition</a>.

  * More on resource bundle concepts and syntax can be found in the 

  * <a href="http://icu.sourceforge.net/userguide/ResourceManagement.html">Users Guide</a>.

  * <P>
