34 : * Revision 1.11 2005/05/21 03:15:18 fwarmerdam
35 : * Removed unused stat buffer.
36 : *
37 : * Revision 1.10 2004/02/27 21:06:03 fwarmerdam
38 : * Better support for "single file" creation ... don't allow other layers to
39 : * be created. But *do* single file to satisfy the first layer creation request
40 : * made. Also, allow creating a datasource "on" an existing directory.
