metasim     00/11/09 15:14:12

  Modified:    src/antidote/org/apache/tools/ant/gui About.java
                        ProjectNavigator.java ProjectProxy.java
                        ProjectTreeModel.java PropertyEditor.java
                        TargetSelectionModel.java
  Added:       src/antidote/org/apache/tools/ant/gui
                        AntTreeCellRenderer.java
  Log:
  Started work on the Ant Construction Set classes (ACS), which will map directly
  to DOM elements allowing easier manipulation of the XML and better editing of
  Ant projects. NB: The code currently requires the Sun JAXP library (which Ant
  needs anyway).
