-kexec-tools \- Tool to load a kernel for warm reboot and initiate a warm reboot
+kexec \- Tool to load a kernel for warm reboot and initiate a warm reboot
.SH SYNOPSIS
-.B kexec-tools
+.B kexec
.RI [ options ] " files" ...
.SH DESCRIPTION
.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
-\fBkexec-tools\fP does not have a man page yet. Please use "kexec -h" for help.
+\fBkexec\fP allows one to load another kernel from the currently running
+Linux kernel. Normally one would load a kernel, and possibly an initial
+ramdisk, into the currently running kernel using kexec and then initiate
+a warm reboot by executing kexec again with appropriate option.
.SH OPTIONS
These programs follow the usual GNU command line syntax, with long
options starting with two dashes (`-').
A summary of options is included below.
-For a complete description, see the Info files.
