+.Dt KGET 8
+.Os BSD 3
+.Sh NAME
+.Nm kget
+.Nd print kernel change information.
+.Sh SYNOPSIS
+.Nm kget
+.Ar filename
+.Sh DESCRIPTION
+The
+.Nm
+utility allows one to view or save any device configuration information
+which was changed in userconfig (-c) session.  Most typically, it is written
+to a /boot/kernel.conf file which is then loaded from /boot/loader.rc
+(using "load -t userconfig_script /boot/kernel.conf"), saving the user
+from having to re-enter it each time the system is booted.
+.Pp
+.Nm
+uses the
+.Xt sysctl 3
+interface to retrieve data from the kernel and requires that at least
+the
+.Ar machdep.uc_devlist
+symbol be present.  If it's not, you may need to update your kernel
+before using this utility.
+.Pp
+Usage:
+.Nm
+.Ar filename
+.Pp
+where 
+.Ar filename
+is either a regular file (which is overwritten) or -, indicating that
+standard output should be used.
+.Sh BUGS
+Sure to be some.
+.Sh SEE ALSO
+.Xr sysctl 3
+.Sh HISTORY
+The
+.Nm
+command appeared in FreeBSD 3.1, as part of the PicoBSD distribution by
+.An Andrzej Bialecki
