.\"O \fBfaillog\fR formats the contents of the failure log,
.\"O \fI/var/log/faillog\fR, and maintains failure counts and
.\"O limits.
.\"O The order of the arguments to \fBfaillog\fR is significant.
.\"O Each argument is processed immediately in the order given.

.\"O The \fB-p\fR flag causes failure entries to be printed in UID
.\"O order.
.\"O Entering \fB-u \fIlogin-name\fR flag will
.\"O cause the failure record for \fIlogin-name\fR only to be printed.
.\"O Entering \fB-t \fIdays\fR will cause only the

.\"O The \fB-t\fR flag overrides the use of \fB-u\fR.
.\"O The \fB-a\fR flag causes all users to be selected.
.\"O When used with the \fB-p\fR flag, this option selects all users
.\"O who have ever had a login failure.
.\"O It is meaningless with the \fB-r\fR flag.
