* $Log: mitab_ogr_driver.cpp,v $
* Revision 1.11 2005/05/21 03:15:18 fwarmerdam
* Removed unused stat buffer.
*
* Revision 1.10 2004/02/27 21:06:03 fwarmerdam
* Better support for "single file" creation ... don't allow other layers to
* be created. But *do* single file to satisfy the first layer creation request
* made. Also, allow creating a datasource "on" an existing directory.
*
* Revision 1.9 2003/03/20 15:57:46 warmerda
* Added delete datasource support
*
* Revision 1.8 2001/01/22 16:03:58 warmerda
* expanded tabs
*
* Revision 1.7 2000/01/26 18:17:00 warmerda
* reimplement OGR driver
*
* Revision 1.6 2000/01/15 22:30:44 daniel
* Switch to MIT/X-Consortium OpenSource license
*
* Revision 1.5 1999/12/15 17:05:24 warmerda
* Only create OGRTABDataSource if SmartOpen() result is non-NULL.
*
* Revision 1.4 1999/12/15 16:28:17 warmerda
* fixed a few type problems
*
* Revision 1.3 1999/12/14 02:22:29 daniel
* Merged TAB+MIF DataSource/Driver into ane using IMapInfoFile class
*
* Revision 1.2 1999/11/12 02:44:36 stephane
* added comment, change Register name.
*
* Revision 1.1 1999/11/08 21:05:51 svillene
* first revision
