+// This file is supposed to serve two purposes:
+// 1. To be a starting point for implementing new tests (for new backends).
+// 2. To exercise (at least some of) the syntax and try the SOCI library
+//    against different compilers, even in those environments where there
+//    is no database. SOCI uses advanced template techniques which are known
+//    to cause problems on different versions of popular compilers, and this
+//    test is handy to verify that the code is accepted by as many compilers
+//    as possible.
+//
+// Both of these purposes mean that the actual code here is meaningless
+// from the database-development point of view. For new tests, you may wish
+// to remove this code and keep only the general structure of this file.
