  Whenever there is any discrepancy between the two licenses,
  the BSD license will take precedence.

  Latest version is available at http://adodb.org/

  Portable version of oci8 driver, to make it more similar to other database drivers.
  The main differences are

   1. that the OCI_ASSOC names are in lowercase instead of uppercase.
   2. bind variables are mapped using ? instead of :<bindvar>

   Should some emulation of RecordCount() be implemented?
