  Modified:    digester build.xml
               digester/src/java/org/apache/commons/digester Digester.java
               digester/src/test/org/apache/commons/digester TestRule.java
  Added:       digester/src/java/org/apache/commons/digester
                        BeanPropertySetterRule.java
               digester/src/test/org/apache/commons/digester
                        BeanPropertySetterRuleTestCase.java
                        SimpleTestBean.java
  Log:
  Add the BeanPropertySetterRule and associated tests.  NOTE:  The test case
  curently fails (target "test.bpsr") -- could someone take a look and see
  what I screwed up in incorporating this stuff?
