-Package cloudsql exposes access to Google Cloud SQL databases.
-
-This package does not work in App Engine "flexible environment".
-
-This package is intended for MySQL drivers to make App Engine-specific
-connections. Applications should use this package through database/sql:
-Select a pure Go MySQL driver that supports this package, and use sql.Open
-with protocol "cloudsql" and an address of the Cloud SQL instance.
-
-A Go MySQL driver that has been tested to work well with Cloud SQL
-is the go-sql-driver:
-	import "database/sql"
-	import _ "github.com/go-sql-driver/mysql"
-
-	db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname")
-
-
-Another driver that works well with Cloud SQL is the mymysql driver:
-	import "database/sql"
-	import _ "github.com/ziutek/mymysql/godrv"
-
-	db, err := sql.Open("mymysql", "cloudsql:instance-name*dbname/user/password")
-
-
-Using either of these drivers, you can perform a standard SQL query.
-This example assumes there is a table named 'users' with
-columns 'first_name' and 'last_name':
-
-	rows, err := db.Query("SELECT first_name, last_name FROM users")
-	if err != nil {
-		log.Errorf(ctx, "db.Query: %v", err)
-	}
-	defer rows.Close()
-
-	for rows.Next() {
-		var firstName string
-		var lastName string
-		if err := rows.Scan(&firstName, &lastName); err != nil {
-			log.Errorf(ctx, "rows.Scan: %v", err)
-			continue
-		}
-		log.Infof(ctx, "First: %v - Last: %v", firstName, lastName)
-	}
-	if err := rows.Err(); err != nil {
-		log.Errorf(ctx, "Row error: %v", err)
-	}
