=== Option Descriptions ===

Most of the "options" are accessible through the '=' command, which provides
an interface to the various "sets" of options available to the player.

In the decriptions below, each option is listed as the textual summary which 
is shown on the "options" screen, plus the internal name of the option in 
brackets, followed by a textual description of the option.

Note that the internal name of the option can be used in user pref files to 
force the option to a given setting, see "macro.txt" for more info.

Various concepts are mentioned in the descriptions below, including "disturb",
(cancel any running, resting, or repeated commands, which are in progress),
"flush" (forget any keypresses waiting in the keypress queue, including any
macros in progress), "fresh" (dump any pending output to the screen), and
"sub-windows" (see below).

=== Option Set 1 -- User Interface ===

These options determine the way the user interface works. 

***** <rogue_like_commands>
Rogue-like commands [rogue_like_commands] (default: no)
    Selects the "roguelike" command set (see "cmddesc.txt" for info).

***** <use_command>
Allow unified use command [use_command] (default: no)
    Unifies the item commands like "zap a rod", "use a staff", "eat food", "aim
    a wand", ... into a general "use object" command. The command in the 
    original keymap is "u", and "Z" in the roguelike mode. The standard 
    commands for eat, quaff, read, zap, aim, ... are still available, to be 
    used for macros.

***** <quick_messages>
Activate quick messages [quick_messages] (default: yes)
    Allows the use of any keypress as a response to the "-more-" prompt (useful
    for monster farming).  Allows most keys to mean "no" to any "[y/n]" prompt.
    Otherwise, "-more-" will respond only to pressing space and you'll 
    explicity have to press 'y' or 'n' at prompts.

***** <other_query_flag>
Prompt for floor item selection [other_query_flag] (default: no)
    Allows the user to select objects from the center of stacks.  Without this 
    option, the uppermost appropriate object will always be selected.

***** <carry_query_flag>
Prompt before picking things up [carry_query_flag] (default: yes)
    Forces the game to ask your permission before allowing you to pick up
    any object.

***** <carry_heavy_query>
Verify before picking up heavy objects [carry_heavy_query] (default: yes)
    Asks you permission when picking up any object heavy enough to slow you
    down.

***** <use_old_target>
Use old target by default [use_old_target] (default: no)
    Forces all commands which normally ask for a "direction" to use the
    current "target" if there is one.  Use of this option can be dangerous
    if you target locations on the ground, unless you clear them when done.

***** <always_pickup>
Pick things up by default [always_pickup] (default: yes)
    Tells the game that walking onto an item should attempt to pick it up.
    Picking up objects in the manner takes no additional energy.  Note the
    "g" and "-" commands, which can be used to "reverse" this option for a
    single turn.

***** <always_repeat>
Repeat obvious commands [always_repeat] (default: yes)
    Tells the game that when you attempt to "open" a door or chest, "bash" a 
    door, "tunnel" through walls, "disarm" traps or chests, or "alter" any 
    grid, that you wish to automatically "repeat" the command 99 times (see
    "cmddesc.txt"), unless an explicit repeat count was given.  Note that in 
    all cases, once the command succeeds, it will no longer repeat.

***** <verify_destroy>
Verify destruction of objects [verify_destroy] (default: yes)
    Prompt for verification of the "destroy" command.

***** <verify_destroy_junk>
Verify destruction of objects [verify_destroy_junk] (default: yes)
    If destroy verification is on, prompt for verification when destroying 
    worthless objects. If this is off, then only "good" objects will 
    require verification.

***** <easy_direction>
Open/Disarm/Close without direction [easy_direction] (default: no)
    If there is only one closed door next to the character, the game will 
    not bother asking for a direction when the player asks to "o"pen 
    something. The same applies for "c"losing doors and "D"isarming traps.

***** <easy_alter>
Open/Disarm doors/traps on movement. [easy_alter] (default: no)
    Moving into a closed door will attempt once to open it, and moving 
    into a trap will attempt once to disarm it. If the player ever wishes
    to leave a known teleport trap as a guaranteed escape route, this 
    option must therefore be off.

***** <easy_floor>
Display floor stacks in a list [easy_floor] (default: no)
    When moving into a stack, if this option is *off*, the character will 
    attempt to pick up items from the stack, from top to bottom, until the 
    stack is gone or the inventory is full. This option allows the player
    to interact with other items than the one at the top of the stack.

***** <verify_leave_quest>
Verify before descending from quest level [verify_leave_quest] (default: yes)
    Asks for confirmation when you try to leave a quest level using down 
    stairs (thereby risking quest failure).

***** <spellbook_menu>
Alternate spellbook interface [spellbook_menu] (default: no)
    Allows you to choose between the two methods of spell power selection.
    If the option is off, you get the menu if you type a lower-case letter
    for the spell: maaa, and the top level spell if you type a captial 
    letter: maA.  If it is on, you get the lowest level power if you type a 
    lower-case letter for the spell: maa, the highest level power if you type
    a upper-case letter: maA, and a menu only if you type a captial letter
    for the spellbook: mAaa.

***** <always_show_lists>
Always show lists in item/spell selection [always_show_lists] (default: yes)
    If this is turned on, item/spell lists will always be show when picking
    items/spells. Otherwise, they'll only appear if requested.

=== Option Set 2 -- Display ===

These options effect display only, and have no real infulence on gameplay.

***** <depth_in_feet>
Show dungeon level in feet [depth_in_feet] (default: no)
    Display dungeon depths in "feet" instead of "levels".

***** <show_labels>
Show labels in equipment listings [show_labels] (default: yes)
    Display "labels" (what an object is being used for) for objects in all
    "equipment" listings.

***** <show_weights>
Show weights in all object listings [show_weights] (default: yes)
    Display "weights" (in pounds) of objects in all "inventory", "equipment",
    "store items", and "home items" listings.

***** <show_choices>
Show choices in inven/equip listings [show_choices] (default: yes)
    Display "choices" (legal responses) in any sub-windows which are being
    used to display your inventory or equipment.  Also, if one sub-window
    is being used to display your inventory or equipment, then this option
    will cause it to be (temporarily) toggled as needed to always show the
    "appropriate" set of objects (inventory or equipment).

***** <show_flavors>
Show flavors in object descriptions [show_flavors] (default: yes)
    Display "flavors" (color or variety) in object descriptions, even for
    objects whose type is known.  This does not affect objects in stores.

***** <show_piles>
Show stacks as white '&' [show_piles] (default: yes)
    Stacks of items on the floor are shown using the "&" symbol in white.
    Otherwise, the top object is shown.

***** <show_trap_piles>
Show objects on traps as red '&' [show_trap_piles] (default: yes)
    Items on top of traps are shown using the "&" symbol in red. Otherwise, the 
    trap is shown.

***** <display_insc_msg>
Display inscriptions in messages [display_insc_msg] (default: no)
    If this is turned on, item inscriptions will appear in all messages. 
    Otherwise, they will only appear in messages in which they are relevant.

***** <hilite_player>
Hilite the player with the cursor [hilite_player] (default: no)
    Place the visible cursor on the player.  This looks fine on some Unix
    machines, but horrible on most graphics machines.  Note that only some
    machines are able to *not* show the cursor, but on those machines, hiding
    the cursor often speeds up the game and looks better.

***** <view_yellow_lite>
Use special colors for torch-lit grids [view_yellow_lite] (default: yes)
    This option causes special colors to be used for "torch-lit" grids in
    certain situations (see "view_granite_lite" and "view_special_lite").
    Turning this option off will slightly improve game speed.

***** <view_bright_lite>
Use special colors for 'viewable' grids [view_bright_lite] (default: yes)
    This option causes special colors to be used for non "viewable" grids
    in certain situations (see "view_granite_lite" and "view_special_lite").
    When this option is set, floor grids which are normally drawn in "white"
    but which are not currently "viewable" by the player are instead drawn
    in "dark gray".  This makes the "viewable" grids to appear "brighter"
    than the others, allowing the player to easily determine which floor
    grids are in "line of sight".  Turning this option off will probably
    increase the speed of the game.

***** <view_granite_lite>
Use special colors for wall grids (slow) [view_granite_lite] (default: no)
    This option activates a special color scheme for all "wall" grids which
    are normally drawn in "white" (as walls and rubble normally are).  When
    the player is blind, we use "dark gray", else if the grid is torch-lit,
    we use "yellow" (or "white") depending on the "view_yellow_lite" option,
    else if the "view_bright_lite" option is set, and the grid is not in line
    of sight, or the grid is dark, or the grid is only "partially" lit, then
    we use "gray", otherwise we use the normal "white".  Turning this option
    off will probably increase the speed of the game.  This option may not
    work well if the attr/char codes for walls/veins have been changed, or
    if "graphics" are being used.

***** <view_special_lite>
Use special colors for floor grids (slow) [view_special_lite] (default: yes)
    This option activates a special color scheme for all "floor" grids which
    are normally drawn in "white" (as they normally are).  When the player is
    blind, we use "dark gray", else if the grid is torch-lit, we use "yellow"
    (or "white") depending on the "view_yellow_lite" option, else if the grid
    is "dark", we use "dark gray", else if the "view_bright_lite" option is
    set, and the grid is not in line of sight, we use "gray", otherwise we
    use the normal "white".  Turning this option off will probably increase
    the speed of the game.  This option may not work well if the attr/char
    codes for walls/veins have been changed, or if "graphics" are being used.

***** <view_monster_lite>
Allow monsters to have light radius [view_monster_lite] (default: yes)
    This option allows certain monsters to produce their own light radius,
    which potentially can slow down the game on slower machines. If this 
    option is off, the relevant monsters will be visible even in darkness
    but will not light up the squares around them.

***** <view_player_color>
Use special colors for the player [view_player_color] (default: yes)
    If this option is turned on, the player symbol (@) will change colors 
    to represent the player's health status.

***** <allow_prefix_colors>
Allow prefixes to determine object color [allow_prefix_colors] (default: yes)
    If this option is turned on, objects with prefixes may be a different
    color than their base objects. This can cause overlap between item types.

=== Option Set 3 -- Disturbance options ===

These options affect what conditions will be handled automatically by the game 
and which will cause it to stop for your intervention.

***** <run_ignore_stairs>
Run past stairs [run_ignore_stairs] (default: yes)
    Ignore stairs when running.

***** <run_ignore_doors>
Run through open doors [run_ignore_doors] (default: yes)
    Ignore open doors when running.

***** <run_cut_corners>
Run past known corners [run_cut_corners] (default: yes)
    Cut sharply around "known" corners when running.  This will result in
    "faster" running, but may cause you to run into a "lurking" monster.

***** <disturb_move>
Disturb whenever any monster moves [disturb_move] (default: yes)
    Disturb the player when any monster moves, appears, or disappears.  This
    includes monsters which are only visible due to telepathy, so you should 
    probably turn this option off if you want to "rest" near such monsters.

***** <disturb_near>
Disturb whenever viewable monster moves [disturb_near] (default: yes)
    Disturb the player when any viewable monster moves, whenever any
    monster becomes viewable for the first time, and also whenever any
    viewable monster becomes no longer viewable.  This option ignores the 
    existance of "telepathy" for the purpose of determining whether a monster
    is "viewable". 

***** <disturb_panel>
Disturb whenever map panel changes [disturb_panel] (default: yes)
    This option causes you to be disturbed by the screen "scrolling", as it 
    does when you get close to the "edge" of the screen.

***** <disturb_state>
Disturb whenever player state changes [disturb_state] (default: yes)
    This option causes you to be disturbed whenever the player state
    changes, including changes in hunger, resistance, confusion, etc.

***** <disturb_minor>
Disturb whenever boring things happen [disturb_minor] (default: yes)
    This option causes you to be disturbed by various bring things,
    including monsters bashing down doors, inventory feelings, and
    beginning to run out of fuel.

***** <display_recharge_msg>
Display messages upon recharge [display_recharge_msg] (default: yes)
    If this is turned on, you will get messages whenever an artifact, rod or 
    talisman recharges.  Also, if you are playing an angel or demon, you'll
    get a message when your racial power recharges.

***** <auto_more>
Automatically clear -more- prompts [auto_more] (default: no)
    The game does not wait for a keypress when it comes to a -more- prompt,
    but carries on going.

***** <ring_bell>
Audible bell (on errors, etc) [ring_bell] (default: yes)
    Attempt to make a "bell" noise when various "errors" occur.

=== Option Set 4 -- Game-play ===

These options affect the way the game is played.

***** <expand_look>
Expand the power of the look command [expand_look] (default: yes)
    Expand the "look" command to allow the user to "look" at grids which
    are not actually in view of the player, allowing the examination of
    objects/monsters which have only been detected by spells, or sensed
    via telepathy.

***** <expand_list>
Expand the power of the list commands [expand_list] (default: yes)
    Expand the "listing" commands so that they "wrap" at the "edges" of
    the appropriate list.  This allows the "look" and "target" commands
    to "cycle" through all appropriate grids forever, and the "identify
    symbol" to browse through all of the monsters of a given type.

***** <center_player>
Center map continuously (very slow) [center_player] (default: no)
    The map always centres on the player with this option on. With it off, it
    is divided into 25 sections, with coordinates (0,0) to (4,4), and will 
    show one section at a time.

***** <view_perma_grids>
Map remembers all perma-lit grids [view_perma_grids] (default: yes)
    Memorize all perma-lit floor grids which are seen by the player.
    This option allows you to keep track of which explored floor grids
    were perma-lit, but does not distinguish between dark floor grids,
    unexplored floor grids, and unknown grids.  Turning off this option
    allows the player to always know which lit floor grids are in line
    of sight, but this is better accomplished by the "view_bright_lite"
    option.  Note that any non-floor grids which is seen by the player
    are always memorized, and "object" which is seen by the player is
    memorized independantly from the memorization of the grid itself.

***** <view_torch_grids>
Map remembers all torch-lit grids [view_torch_grids] (default: no)
    Memorize all (torch-lit) floor grids which are seen by the player.
    This option not only allows you to keep track of which floor grids
    have been explored, but also which ones are "dark", because the use
    of this option activates a special "color scheme" for the display of
    floor grids, in which "dark" grids are drawn in "dark gray", "lit"
    grids are drawn in "white", and (if the "view_bright_lite" option is
    set) "lit" grids which are also in line of sight are drawn in "orange".
    Note that grids which are currently "torch-lit" are considered to be
    "lit", and are thus drawn in "white", unless the "view_yellow_lite"
    option is set, in which case they are drawn in "yellow".

***** <dungeon_align>
Generate dungeons with aligned rooms [dungeon_align] (default: yes)
    Force all rooms to be "aligned" with the "panel" divisions.  This results
    in a much "prettier" dungeon, but may result in fewer greater vaults.

***** <stack_force_notes>
Merge inscriptions when stacking [stack_force_notes] (default: yes)
    Force otherwise identical objects to merge, even if one has an empty
    inscription and the other does not.  The resulting stack keeps the 
    non-empty inscription.

***** <stack_force_costs>
Merge discounts when stacking [stack_force_costs] (default: yes)
    Force otherwise identical objects to merge, even if they have different
    discounts.  The resulting stack keeps the largest discount.  This option
    may cause you to lose "value", but will give you optimal pack usage.

***** <scroll_target>
Scroll map while targetting [scroll_target] (default: yes)
    This allows the player to target monsters which are off-screen from the 
    player's point of view, as the view will scroll to show the whereabouts of 
    all monsters in line of sight so the player can target them.

***** <display_room_desc>
Display room descriptions [display_room_desc] (default: no)
    If this option is on, every time you enter a room you'll get a message
    describing its contents.  This message may give you some warning of 
    invisible monsters or traps.  If this option is off, your play will not be
    interrupted by the messages, though you will still be able to see them on
    a sub-window if you so choose.

***** <inscribe_unique>
Auto-inscribe unique drops [inscribe_unique] (default: no)
    Automatically inscribes unique's drops with their name.

=== Option Set 5 -- Efficiency ===

These options may be used to optimize the game on slower machines.

***** <view_reduce_lite>
Reduce lite-radius when running [view_reduce_lite] (default: no)
    Reduce the "radius" of the player's "lite" to that of a "torch" when the 
    player is "running", which makes running more "efficient", but can be 
    disconcerting.

***** <hidden_player>
Hide player symbol when running [hidden_player] (default: no)
    Hide the player symbol when the player is "running", which makes the game 
    somewhat faster.

***** <avoid_abort>
Avoid checking for user abort [avoid_abort] (default: no)
    Avoid checking to see if the user has pressed a key during resting or 
    running or repeated commands.  This not only makes the game much more 
    efficient (on many systems), but also allows the use of certain obscure 
    macro sequences, such as turning this option on, resting until done, 
    turning this option off, and casting a spell.  Note that the use of this 
    option may be dangerous on certain "graphic" machines.  Resting for long 
    periods of time with this option set is dangerous since the resting may 
    not stop until the user takes damage from starvation.

***** <avoid_other>
Avoid processing special colors [avoid_other] (default: no)
    Avoid processing the "multi-hued" or "clear" attributes of monsters.
    This will cause all "multi-hued" monsters to appear "violet" and all
    "clear" monsters to appear "white", and will cause "trappers" and
    "lurkers" to be visible on some machines, but it may greatly increase
    efficiency especially when telepathy is active.  Certain systems may
    choose to set this option if they are unable to support the special
    "color" processing, but if they handle graphics "correctly", by using
    attr/char pairs with the "high bits" set, then not only will the game
    correctly avoid using any "dangerous" color processing, but it will
    allow such processing to occur when it is not dangerous.  So if you
    are using graphics, and you use a "normal" attr/char for the "floor"
    grids, then you can use the "special lighting effects" for floors.

***** <flush_failure>
Flush input on various failures [flush_failure] (default: yes)
    This option forces the game to flush all pending input whenever various
    "failures" occur, such as failure to cast a spell, failure to use a wand,
    etc.  This is very useful if you use macros which include "directional"
    components with commands that can fail, since it will prevent you from
    walking towards monsters when your spells fail.

***** <flush_disturb>
Flush input whenever disturbed [flush_disturb] (default: no)
    This option forces the game to flush all pending input whenever the
    character is "disturbed".  This is useful if you use macros which take
    time, since it will prevent you from continuing your macro while being
    attacked by a monster.

***** <fresh_before>
Flush output before every command [fresh_before] (default: yes)
    This option forces the game to flush all output before every command.
    This will give you maximal information, but may slow down the game
    somewhat.  Note that this option is only useful when using macros,
    resting, running, or repeating commands, since the outout is always
    flushed when the game is waiting for a keypress from the user.

***** <fresh_after>
Flush output after certain things [fresh_after] (default: no)
    This option forces the game to flush all output after not only every
    player command, but also after every round of processing monsters and
    objects, and after every message, which will maximize your information,
    but may slow down the game a lot, especially on slower machines, and on
    faster machines you cannot see the results anyway.

***** <compress_savefile>
Compress messages in savefiles [compress_savefile] (default: yes)
    Compress the savefile, by only saving the most recent "messages" that
    the player has received.  This can cut the size of the savefile by a
    drastic amount, but will result in the loss of message information.

***** <run_avoid_center>
Avoid centering while running [run_avoid_center] (default: no)
    The map does not centre on the player if the player moves with the "run" 
    command, only when the running finishes.
