-+.Nm zap [string [...]]
++.Nm zap [-s NUM] [-y] string [...]]
 +.Sh DESCRIPTION
 +.Nm Zap
-+takes zero or more strings, looks for each in the output of a
++takes one or more strings, looks for each in the output of a
 +.Nm ps
 +command that it runs, and for each process whose
 +.Nm ps
 +line matches the string, prints the line as a prompt.
 +If you reply with a
 +.Nm y,
-+the program attempts to deliver a signal to the given process.
-+If no
++the program attempts to deliver a signal SIGERM to the given process.
++If a zero-length
 +.Nm string
 +is given, then every process will be prompted for.
++.PP
++The 
++.B -y
++option tells the program to just do it, not to ask for confirmation.
++It makes the program non-interactive.
++.PP
++The 
++.B -s
++.I signum
++option takes a numeric (only) argument, which is the signal number
++to send. In the absence of this option, SIGTERM is sent.
