+# This file implements tests for the "sqlite3_trace()" API. Specifically,
+# it tests the special handling of nested SQL statements (those executed
+# by virtual table or user function callbacks). These statements are treated
+# differently in two respects:
+#
+#   1. Each line of the statement is prefixed with "-- " to turn it into
+#      an SQL comment.
+#
+#   2. Parameter expansion is not performed.
