/*
 * This is a configuration program that will create a base XF86Config
 * file based on menu choices. Its main feature is that clueless users
 * may be less inclined to select crazy sync rates way over monitor spec,
 * by presenting a menu with standard monitor types. Also some people
 * don't read docs unless an executable that they can run tells them to.
 *
 * It assumes a 24-line or bigger text console.
 *
 * Revision history:
 * 25Sep94 Initial version.
 * 27Sep94 Fix hsync range of monitor types to match with best possible mode.
 *         Remove 'const'.
 *         Tweak descriptions.
 * 28Sep94 Fixes from J"org Wunsch:
 *           Don't use gets().
 *           Add mouse device prompt.
 *           Fix lines overrun for 24-line console.
 *         Increase buffer size for probeonly output.
 * 29Sep94 Fix bad bug with old XF86Config preserving during probeonly run.
 *         Add note about vertical refresh in interlaced modes.
 *         Name gets() replacement getstring().
 *         Add warning about binary paths.
 *         Fixes from David Dawes:
 *           Don't use 'ln -sf'.
 *           Omit man path reference in comment.
 *           Generate only a generic 320x200 SVGA section for accel cards.
 *	     Only allow writing to /usr/X11R6/lib/X11 if root, and use
 *	       -xf86config for the -probeonly phase (root only).
 *         Fix bug that forces screen type to accel in some cases.
 * 30Sep94 Continue after clocks probe fails.
 *         Note about programmable clocks.
 *         Rename to 'xf86config'. Not to be confused with XF86Config
 *           or the -xf86config option.
 * 07Oct94 Correct hsync in standard mode timings comments, and include
 *           the proper +/-h/vsync flags.
 * 11Oct94 Skip 'numclocks:' and 'pixel clocks:' lines when probing for
 * 	     clocks.
 * 18Oct94 Add check for existence of /usr/X11R6.
 *	   Add note about ctrl-alt-backspace.
 * 06Nov94 Add comment above standard mode timings in XF86Config.
 * 24Dec94 Add low-resolution modes using doublescan.
 * 29Dec94 Add note in horizontal sync range selection.
 *	   Ask about ClearDTR/RTS option for Mouse Systems mice.
 *	   Ask about writing to /etc/XF86Config.
 *	   Allow link to be set in /var/X11R6/bin.
 *	   Note about X -probeonly crashing.
 *	   Add keyboard Alt binding option for non-ASCII characters.
 *	   Add card database selection.
 *	   Write temporary XF86Config for clock probing in /tmp instead
 *	     of /usr/X11R6/lib/X11.
 *	   Add RAMDAC and Clockchip menu.
 * 27Mar99 Modified for XFree86 4.0 config file format
 * 06Sep02 Write comment block about 'DontVTSwitch'.
 *
 * Possible enhancements:
 * - Add more standard mode timings (also applies to README.Config). Missing
 *   are 1024x768 @ 72 Hz, 1152x900 modes, and 1280x1024 @ ~70 Hz.
 *   I suspect there is a VESA standard for 1024x768 @ 72 Hz with 77 MHz dot
 *   clock, and 1024x768 @ 75 Hz with 78.7 MHz dot clock. New types of
 *   monitors probably work better with VESA 75 Hz timings.
 * - Add option for creation of clear, minimal XF86Config.
 * - The card database doesn't include most of the entries in previous
 *   databases.
 *
 * Send comments to H.Hanemaayer@inter.nl.net.
 *
 * Things to keep up-to-date:
 * - Accelerated server names.
 * - Ramdac and Clockchip settings.
 * - The card database.
 *
