import "github.com/juju/juju/agent" // Get the value of a configuration option maxConns := agent.Config()["maxConns"] // Modify a configuration option agent.Config()["maxConns"] = 100In these examples, the `Config()` method is called from the `agent` package of the Juju library. This method returns a map of configuration values, which can be accessed and modified using the standard map syntax. This can be useful for configuring Juju agents at runtime without having to recompile or redeploy the application. Overall, the `github.com.juju.juju.agent` package provides a convenient way to access and modify configuration values in Juju agents using Go code.
