+.Sh USAGE
+This function is a direct replacement for the
+.Bx
+.Fn signal
 function for simple applications that are installing a single-argument signal
-handler function.  If a \fBBSD\fR signal handler function is being installed
+handler function.  If a
+.Bx
+signal handler function is being installed
 that expects more than one argument, the application has to be modified to use
-\fBsigaction\fR(2). The \fBbsd_signal()\fR function differs from
-\fBsignal\fR(3UCB) in that the \fBSA_RESTART\fR flag is set and the
-\fBSA_RESETHAND\fR will be clear when \fBbsd_signal()\fR is used.  The state of
-these flags is not specified for \fBsignal\fR(3UCB).
