REM \brief  Deregister Connector/ODBC driver registered with
REM         Install.bat
REM
REM         This exists for those working with the Windows 
REM         source distribution or with installer-less 
REM         binary distribution.
REM
REM         If driver was registerd under non-default name,
REM         the name used should be specified as first 
REM         parameter of this script.
REM
REM         Note that you should manually remove all data
REM         sources using a driver before uninstalling that
REM         driver.
