+ * |
+ * <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://source.icu-project.org/repos/icu/icuhtml/trunk/design/bnf_rb.txt">BNF definition</a>. |
+ * More on resource bundle concepts and syntax can be found in the |
+ * <a href="http://icu-project.org/userguide/ResourceManagement.html">Users Guide</a>. |
