-The \fBerr()\fR and \fBwarn()\fR family of functions display a formatted error
-message on the standard error output. In all cases, the last component of the
-program name, followed by a colon character and a space, are output. If the
-\fIfmt\fR argument is not \fINULL\fR, the formatted error message is output. In
-the case of the \fBerr()\fR, \fBverr()\fR, \fBwarn()\fR, and \fBvwarn()\fR
-functions, the error message string affiliated with the current value of the
-global variable \fBerrno\fR is output next, preceded by a colon character and a
-space if \fIfmt\fR is not \fINULL\fR. In all cases, the output is followed by a
-newline character.  The \fBerrx()\fR, \fBverrx()\fR, \fBwarnx()\fR, and
-\fBvwarnx()\fR functions will not output this error message string.

+.Sh WARNINGS
 It is important never to pass a string with user-supplied data as a format
-without using `%s'. An attacker can put format specifiers in the string to
-mangle the stack, leading to a possible security hole. This holds true even if
-the string has been built ``by hand'' using a function like \fBsnprintf\fR(3C),
+without using
+.Sq %s .
+An attacker can put format specifiers in the string to mangle the stack,
+leading to a possible security hole.
+This holds true even if the string has been built by hand using a function
+like
+.Xr snprintf 3C ,
 as the resulting string can still contain user-supplied conversion specifiers
-for later interpolation by the \fBerr()\fR and \fBwarn()\fR functions.
