 **Description:** A list of names of signals to be sent to a process or sleeps
 between signals.
 
-Signals from the given list are sent to the process in a sequence. Special
-strings of the form `Ns` or just `N` where `N` is a positive integer can be used
-to add sleeps between the signals. On Windows, only the kill signal is
-supported, which terminates the process.
