+.Sh DESCRIPTION
+The
+.Nm
+utility is used to create an image for Das U-Boot, the
+.Qq Universal Boot Loader .
+.Pp
+The arguments are as follows:
+.Bl -tag -width indent
+.It Fl A No ( arm Ns | Ns arm64 Ns | Ns i386 Ns | Ns mips Ns | Ns mips64 Ns | Ns or1k Ns | Ns powerpc )
+Defines the architecture.
+This is required.
+.It Fl a Ar address
+Sets the image load address.
+This is an integer between 0 and
+.Dv UINT32_MAX .
+This is required.
+.It Fl C No ( bz2 Ns | Ns gz Ns | Ns lzma Ns | Ns lzo Ns | Ns none )
+Defines the compression.
+The default is
+.Qq none .
+.It Fl E Ar address
+Define the entry point.
+This is an integer between 0 and
+.Dv UINT32_MAX .
+This option is the same as
+.Fl e
+but it inverts the bytes to convert the 32 bit integer
+from little to big endian (or vice versa).
+If
+.Fl E
+or
+.Fl e
+are not set, the entry point defaults to the
+image load address
+.Pq Fl a .
+.It Fl e Ar address
+Define the entry point.
+This is an integer between 0 and
+.Dv UINT32_MAX .
+If
+.Fl E
+or
+.Fl e
+are not set, the entry point defaults to the
+image load address
+.Pq Fl a .
+.It Fl h
+Display the usage and exit.
+.It Fl m Ar magic
+Set the magic.
+This is an integer between 0 and
+.Dv UINT32_MAX .
+The default is
+.Qq 0x27051956 .
+.It Fl n Ar image
+Defines the image name.
+This is required.
+.It Fl O No ( freebsd Ns | Ns linux Ns | Ns netbsd Ns | Ns openbsd )
+Defines the operating system type.
+The default OS name is
+.Qq netbsd .
+.It Fl T No ( fs Ns | Ns kernel Ns | Ns ramdisk Ns | Ns standalone Ns | Ns script )
+Defines the image type.
+This is required.
+.El
+.Pp
+The required
+.Ar source
+argument is the filename of the kernel that is read.
+The required
+.Ar destination
+argument is the filename of the image file that is created.
+.\"
+.Sh RETURN VALUES
+.Nm
+returns 1 on failure to read the kernel,
+generate a header, or create the image.
+.\"
+.Sh EXAMPLES
+Before the image is written, the header is displayed to standard out;
+for example:
+.Bd -literal -offset 0
