Ant task to compile attribute indexes. Usage:

     <taskdef resource="org/apache/commons/attributes/anttasks.properties"/>
     
     <attribute-indexer jarFile="myclasses.jar">
         <classpath>
             ...
         </classpath>
     </attribute-indexer>
 

The task will inspect the classes in the given jar and add a META-INF/attrs.index file to it, which contains the index information. The classpath element is required and must contain all dependencies for the attributes used.
