-.SH NAME
-ovs\-kill \- kills processes given their pidfiles
-
-.SH SYNOPSIS
-.B ovs\-kill
-[\fIoptions\fR] \fIpidfile\fR [\fIpidfile\fR...]
-
-.SH DESCRIPTION
-The \fBovs\-kill\fR program reads each \fIpidfile\fR specified on the
-command line and sends a signal to the program associated with it, if
-any. It reads one line of text from \fIpidfile\fR, which must contain
-the PID of the process to kill as a text string. It then uses
-\fBfcntl\fR(2) to verify that a process with the PID from the file
-owns a lock on \fIpidfile\fR before it sends the signal.
-
-A \fIpidfile\fR whose name begins with \fB/\fR is used literally.
-Otherwise, \fB@RUNDIR@/\fR is prefixed.
-
-This program exists for use by \fBovs\-switch\-setup\fR, which cannot
-easily implement its functionality since Perl has no portable
-interface to \fBfcntl\fR-based file locking.
-
-.SH OPTIONS
-.TP
-\fB\-s \fInumber\fR|\fIname\fR, \fB\-\^\-signal=\fInumber\fR|\fIname\fR
-Sets the signal to be sent to each process. Signals may be given by
-number (e.g. \fB1\fR) or by name (e.g. \fBHUP\fR or \fBSIGHUP\fR).
-By default, \fBSIGTERM\fR is sent.
-
-.TP
-\fB\-f\fR, \fB\-\^\-force\fR
-Causes \fBovs\-kill\fR to ignore all errors without printing a message
-to \fBstderr\fR, and to exit with return code 0.
-
-.so lib/common.man
-
-.SH "EXIT CODE"
-
-Without \fB\-f\fR or \fB\-\^\-force\fR, \fBovs\-kill\fR exits with
-status 0 if at least one \fIpidfile\fR was given and the process
-represented by every \fIpidfile\fR was signaled successfully,
-otherwise with status 1.
-
-With \fB\-f\fR or \fB\-\^\-force\fR, \fBovs\-kill\fR always exits with
-status 0.
-
-.SH BUGS
-
-There is a race between verifying the lock on \fIpidfile\fR and
-actually killing the process.
-
-\fBovs\-kill\fR does not wait for the signaled processes to die before
-exiting.
