+For each control character <i>c</i> sent to the control pipe, <b>runsv</b> first
+checks if <i>service/control/<i>c</i> exists and is executable. If so, it starts <i>service</i>/control/<i>c</i>
+and waits for it to terminate, before interpreting the command. If the program
+exits with return code 0, <b>runsv</b> refrains from sending the service the corresponding
+signal. The command <i>o</i> is always considered as command <i>u</i>. The control of the
+optional log service cannot be customized.
