//! service_spaghetti - An example of messy service management.
|
|
//!
|
|
//! This example demonstrates how the service manager behaves when commands
|
|
//! are issued in a less-than-ideal order, such as starting a service that's
|
|
//! already running or removing a service that hasn't been stopped.
