+.Sh NAME
+.Nm fdcontrol
+.Nd modify floppy disk parameters
+.Sh SYNOPSIS
+.Nm fdcontrol
+.Ar device
+.Sh DESCRIPTION
+.Nm Fdcontrol
+allows the specification of device parameters for the floppy disk at
+.Ar device .
+.Ar Device
+should be a character device.
+
+Since the implications of such a specification are considered harmful,
+the underlying
+.Xr ioctl 2
+command is restricted to the super-user.
+
+The command asks the user for each individual tunable parameter,
+defaulting to the currently used value.
+
+.Sh DIAGNOSTICS
+Error codes for the underlying
+.Xr ioctl 2
+commands are printed by the
+.Xr perror 3
+facility.
+
+.Sh BUGS
+The
+.Nm
+command is currently under development. It's user interface is rather
+silly and likely to change in future, options should be provided to
+allow anything being modified from the command line.
+
+.Sh SEE ALSO
+.Xr fd 4 ,
+.Xr ioctl 2 ,
+.Xr perror 3 .
+.Sh HISTORY
+.Nm Fdcontrol
+is currently under development. It's user interface and overall
+functionality are subjects to future improvements and changes.
+.Sh AUTHOR
+The program has been contributed by
+.if n Joerg Wunsch,
+.if t J\(:org Wunsch,
+Dresden.
