+.IR "The following sections are informative."
+.SH "APPLICATION USAGE"
+This utility is typically used in shell scripts, as shown in the
+EXAMPLES section. The special built-in utility
+.BR :
+is sometimes more efficient than

+.nf
+\fB
+while true
+do
+ command
+done
+.fi \fR

+.RE
+.SH RATIONALE
+The
+.IR true
+utility has been retained in this volume of POSIX.1\(hy2008, even though the shell special
+built-in
+.BR :
+provides similar functionality, because
+.IR true
+is widely used in historical scripts and is less cryptic to novice
+script readers.
