// SqliteTest.cs - Test for the Sqlite ADO.NET Provider in Mono.Data.SqliteClient
//                 This provider works on Linux and Windows and uses the native
//                 sqlite.dll or sqlite.so library.
//
// Modify or add to this test as needed...
//
// SQL Lite can be downloaded from
// http://www.hwaci.com/sw/sqlite/download.html
//
// There are binaries for Windows and Linux.
//
// To compile:
//  mcs SqliteTest.cs -r System.Data.dll -r Mono.Data.SqliteClient.dll
//
