/*
 * Configure.c: real-time option control.
 * To add your own option to the XPilot client do the following:
 * 1: Define storage for the option value in either client.c/paint.c/xinit.c
 *    or use a bit in the instruments option set (using the SHOW_XXX macros).
 * 2: Add a declaration for this storage to either client.h/paint.h/xinit.h
 *    or, in case a bit in instruments is used, add a SHOW_ macro to client.h.
 * 3: Add an X resource record to the XrmOptionDescRec options[] table in
 *    default.c to have it recognised by the X resource manager routines.
 * 4: Have it set at startup by the Parse_options() routine in default.c.
 * 5: Add the functionality of your option, probably in the same file
 *    as the storage for the option was defined in.
 * 6: Add it to configure.c (this file) as follows:
 *   a) Determine if it needs either a bool/int/float widget
 *      and find a similar option from which you can copy code.
 *   b) Add the Config_create_XXX function prototype at the top of this file.
 *   c) Add the Config_create_XXX function name to the config_creator[] table.
 *      The order in this table determines the order of the options on screen.
 *   d) Define the Config_create_XXX function similar to one of the others.
 *   e) If it needs a callback when the value changes then add a
 *      Config_update_XXX() function after the other update callbacks
 *      and declare a prototype for the callback at the top of this file.
 *      The Config_update_XXX() function should be given as an argument to
 *      the Config_create_bool/int/float() creator in Config_create_XXX().
 *      If the option doesn't need a callback then the calback argument
 *      should be given as NULL.
 *   f) Add one line to the Config_save() routine to have the option saved.
 * 7: Document your option in the manual page for the client.
 * 8: Mail a context diff (diff -c old new) of your changes to xpilot@cs.uit.no.
