                        Selectors.java
               vfs/src/test/org/apache/commons/vfs/test FileInfo.java
                        VerifyingFileSelector.java
  Removed:     vfs/src/java/org/apache/commons/vfs FileConstants.java
  Log:
  - FileObject:
      - Added getChild() and findFiles().
      - Fixed problem when isReadable() or isWriteable() is the first method
        called on a FileObject.
  - Changes to FileSelector:
      - Methods now throw Exception, rather than FileSystemException.
      - Specify the order that methods are called.
      - Added FileTypeSelector to select on file type.
      - Renamed FileConstants to Selectors.
  - Renamed FileSystemManager.convert() to toFileObject().
  - Renamed FileSystem.findFile() to resolveFile().
  - More javadoc.
