/**
** USERCONFIG
**
** Kernel boot-time configuration manipulation tool for FreeBSD.
**
** Two modes of operation are supported : the default is the line-editor mode,
** the command "visual" invokes the fullscreen mode.
**
** The line-editor mode is the old favorite from FreeBSD 2.0/20.05 &c., the
** fullscreen mode requires syscons or a minimal-ansi serial console.
**/
/**
** USERCONFIG, visual mode.
**
** msmith@atrad.adelaide.edu.au
**
** Look for "EDIT THIS LIST" to add to the list of known devices
**
**
** There are a number of assumptions made in this code.
**
** - That the console supports a minimal set of ANSI escape sequences
** (See the screen manipulation section for a summary)
** and has at least 24 rows.
** - That values less than or equal to zero for any of the device
** parameters indicate that the driver does not use the parameter.
** - That the only tunable parameter for PCI devices are their flags.
** - That flags are _always_ editable.
**
** Devices marked as disabled are imported as such. It is possible to move
** a PCI device onto the inactive list, but it is not possible to actually
** prevent the device from being probed. The ability to move is considered
** desirable in that people will complain otherwise 8)
**
** For this tool to be useful, the list of devices below _MUST_ be updated
** when a new driver is brought into the kernel. It is not possible to
** extract this information from the drivers in the kernel, as the devconf
** structure for the device is not registered until the device is probed,
** which is too late.
**
** XXX - TODO:
**
** - FIX OPERATION WITH PCVT!
**
** - Display _what_ a device conflicts with.
** - Implement page up/down (as what?)
** - Wizard mode (no restrictions)
** - Find out how to put syscons back into low-intensity mode so that the
** !b escape is useful on the console.
** - The min and max values used for editing parameters are probably
** very bogus - fix?
**
** - Only display headings with devices under them. (difficult)
