-.Os
-.Dt KZIP 8
-.Sh NAME
-.Nm kzip
-.Nd compresses kernels
-.Sh SYNOPSIS
-.Nm
-.Op Fl v
-.Op Fl l Ar loadaddr
-.Ar kernel
-.Sh DESCRIPTION
-This program compresses a kernel using
-.Xr gzip 1
-to reduce its disk storage requirements.
-It does not reduce the memory footprint once loaded into memory.
-You lose all the symbols, so usability is limited.
-Its main usage is making kernels for install and fixit floppies, etc.
-.Pp
-The following options are available:
-.Bl -tag -width flag
-.It Fl v
-Verbose mode, reports how much memory is being used by the kernel
-after compression. Also allows you to check to make sure your kernel
-is not going past the 4MB boundary.
-.It Fl l Ar loadaddr
-Specify the address to load the kernel into memory at.
-.Sh DIAGNOSTICS
-The
-.Nm
-utility returns with exit code 1 if given invalid arguments.
-Exit code two means
-.Nm
-was unable to read or process the kernel file.
-.Sh SEE ALSO
-.Xr gzip 1
-.\" .Sh STANDARDS
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Fx 2.0.5 .
-Obtained from Linux via 386BSD -- based on tools/build.c by Linus Torvalds,
-and ported to 386BSD by Serge Vakulenko.
-.Sh AUTHORS
-This man page was written by
-.An David E. O'Brien .
