  13  *  SYNOPSIS START
  14
  15     This sample program demonstrates the cross-platform ODBC database classes
  16     donated by the development team at Remstar International.
  17
  18     The table this sample is based on is developer contact table, and shows
  19     some of the simple uses of the database classes wxDb and wxDbTable.
