    33  * <h2>C API: Resource Bundle</h2>
       
    34  *
       
    35  * C API representing a collection of resource information pertaining to a given
       
    36  * locale. A resource bundle provides a way of accessing locale- specific information in
       
    37  * a data file. You create a resource bundle that manages the resources for a given
       
    38  * locale and then ask it for individual resources.
       
    39  * <P>
       
    40  * Resource bundles in ICU4C are currently defined using text files which conform to the following
       
    41  * <a href="http://dev.icu-project.org/cgi-bin/viewcvs.cgi/~checkout~/icuhtml/design/bnf_rb.txt">BNF definition</a>.
       
    42  * More on resource bundle concepts and syntax can be found in the 
       
    43  * <a href="http://icu.sourceforge.net/userguide/ResourceManagement.html">Users Guide</a>.
