 .SH NAME
 top \- show processes sorted by CPU usage
 .SH SYNOPSIS
-.B top
+\fBtop\fP [\fB\-s\fIdelay\fP] [\fB\-B\fP]
 .SH DESCRIPTION
 Top displays a list of all running processes, once every update interval
 (currently 5 seconds). It is sorted by the CPU usage of the processes in
 the last interval. The first display is the CPU usage of processes since
 the boot time.
 
+.SH OPTIONS
+.PP
+  \fB\-s\fP\fIdelay\fP The number of seconds between screen updates.

+  \fB\-B\fP Blocked-verbose mode.
+  For every process that is blocked,

+  that is either not blocked or blocked on ANY.

 At the top of the screen, top shows the current system load averages in
 the last 1-minute, 5-minute and 15-minute intervals. Then, over the
 last top interval it displays: the number of alive, active, and sleeping
 processes; memory free; and CPU usage. CPU usage is split into
-user, kernel, system and idle time. Kernel time is time spent by kernel tasks,
-that is tasks that run in kernel mode in kernel address space. System
-time are system user processes, such as drivers and servers. User
-time is all other CPU time.

 Then it displays all the alive processes sorted by CPU usage in the last
 interval, with a number of fields for every process. Currently the
