-.SH NAME
-sail \- multi-user wooden ships and iron men
-.SH SYNOPSIS
-.B sail
-[

-.SH DESCRIPTION
-.I Sail
-is a computer version of Avalon Hill's game of fighting sail
-originally developed by S. Craig Taylor.
-.PP
-Players of
-.I Sail
-take command of an old fashioned Man of War and fight other
-players or the computer.  They may re-enact one of the many
-historical sea battles recorded in the game, or they can choose
-a fictional battle.
-.PP
-As a sea captain in the
-.I Sail
-Navy, the player has complete control over the workings of his ship.
-He must order every maneuver, change the set of his sails, and judge the
-right moment to let loose the terrible destruction of his broadsides.
-In addition to fighting the enemy, he must harness the powers of the wind
-and sea to make them work for him.  The outcome of many battles during the
-age of sail was decided by the ability of one captain to hold the `weather
-gage.'
-.PP
-The flags are:
-.TP
-.B \-s
-Print the names and ships of the top ten sailors.
-.TP
-.B \-l
-Show the login name.  Only effective with \fB-s\fP.
-.TP
-.B \-x
-Play the first available ship instead of prompting for a choice.
-.TP
-.B \-b
-No bells.
-.SH IMPLEMENTATION
-.I Sail
-is really two programs in one.  Each player starts up a process which
-runs his own ship.  In addition, a
-.I driver
-process is forked (by the first player) to run the computer ships
-and take care of global bookkeeping.
-.PP
-Because the
-.I driver
-must calculate moves for each ship it controls, the
-more ships the computer is playing, the slower the game will appear.
-.PP
-If a player joins a game in progress, he will synchronize
-with the other players (a rather slow process for everyone), and
-then he may play along with the rest.
-.PP
-To implement a multi-user game in Version 7 UNIX, which was the operating
-system
-.I Sail
-was first written under, the communicating processes must use a common
-temporary file as a place to read and write messages.  In addition, a
-locking mechanism must be provided to ensure exclusive access to the
-shared file.  For example,
-.I Sail
-uses a temporary file named /tmp/#sailsink.21 for scenario 21, and
-corresponding file names for the other scenarios.  To provide exclusive
-access to the temporary file,
-.I Sail
-uses a technique stolen from an old game called "pubcaves" by Jeff Cohen.
-Processes do a busy wait in the loop
-.br
-.sp
-.ce 2
-	for (n = 0; link(sync_file, sync_lock) < 0 && n < 30; n++)
-		sleep(2);
-.br
-.sp
-until they are able to create a link to a file named "/tmp/#saillock.??".
-The "??" correspond to the scenario number of the game.  Since UNIX
-guarantees that a link will point to only one file, the process that succeeds
-in linking will have exclusive access to the temporary file.
-.PP
-Whether or not this really works is open to speculation.  When ucbmiro
-was rebooted after a crash, the file system check program found 3 links
-between the
-.I Sail
-temporary file and its link file.
-.SH CONSEQUENCES OF SEPARATE PLAYER AND DRIVER PROCESSES
-When players do something of global interest, such as moving or firing,
-the driver must coordinate the action with the other ships in the game.
-For example, if a player wants to move in a certain direction, he writes a
-message into the temporary file requesting the driver to move his ship.
-Each ``turn,'' the driver reads all the messages sent from the players and
-decides what happened.  It then writes back into the temporary file new
-values of variables, etc.
-.PP
-The most noticeable effect this communication has on the game is the
-delay in moving.  Suppose a player types a move for his ship and hits
-return.  What happens then?  The player process saves up messages to
-be written to the temporary file in a buffer.  Every 7 seconds or so, the
-player process gets exclusive access to the temporary file and writes
-out its buffer to the file.  The driver, running asynchronously, must
-read in the movement command, process it, and write out the results.  This
-takes two exclusive accesses to the temporary file.  Finally, when the player
-process gets around to doing another 7 second update, the results of the
-move are displayed on the screen.  Hence, every movement requires four
-exclusive accesses to the temporary file (anywhere from 7 to 21 seconds
-depending upon asynchrony) before the player sees the results of his moves.
-.PP
-In practice, the delays are not as annoying as they would appear.  There
-is room for "pipelining" in the movement.  After the player writes out
-a first movement message, a second movement command can then be issued.
-The first message will be in the temporary file waiting for the driver, and
-the second will be in the file buffer waiting to be written to the file.
-Thus, by always typing moves a turn ahead of the time, the player can
-sail around quite quickly.
-.PP
-If the player types several movement commands between two 7 second updates,
-only the last movement command typed will be seen by the driver.  Movement
-commands within the same update "overwrite" each other, in a sense.
-.SH THE HISTORY OF SAIL
-I wrote the first version of
-.I Sail
-on a PDP 11/70 in the fall of 1980.  Needless to say, the code was horrendous,
-not portable in any sense of the word, and didn't work.  The program was not
-very modular and had fseeks() and fwrites() every few lines.  After a
-tremendous rewrite from the top down, I got the first working version up by
-1981.  There were several annoying bugs concerning firing broadsides and
-finding angles.
-.I Sail
-uses no floating point, by the way, so the direction routines are rather
-tricky.
-Ed Wang rewrote my angle() routine in 1981 to be more correct (although
-it still doesn't work perfectly), and he added code to let a player select
-which ship he wanted at the start of the game (instead of the first one
-available).
-.PP
-Captain Happy (Craig Leres) is responsible for making
-.I Sail
-portable for the first time.  This was no easy task, by the way.  Constants
-like 2 and 10 were very frequent in the code.  I also became famous for
-using "Riggle Memorial Structures" in
-.I Sail.
-Many of my structure references are so long that they run off the line
-printer page.  Here is an example, if you promise not to laugh.
-.br
-.sp
-.ce
-specs[scene[flog.fgamenum].ship[flog.fshipnum].shipnum].pts
-.br
-.sp
-.PP
-.I Sail
-received its fourth and most thorough rewrite in the summer and fall
-of 1983.  Ed Wang rewrote and modularized the code (a monumental feat)
-almost from scratch.  Although he introduced many new bugs, the final
-result was very much cleaner and (?) faster.  He added window movement
-commands and find ship commands.
-.SH HISTORICAL INFO
-Old Square Riggers were very maneuverable ships capable of intricate
-sailing.  Their only disadvantage was an inability to sail very
-close to the wind.  The design of a wooden ship allowed only for the
-guns to bear to the left and right sides.  A few guns of small
-aspect (usually 6 or 9 pounders) could point forward, but their
-effect was small compared to a 68 gun broadside of 24 or 32 pounders.
-The guns bear approximately like so:
-.nf
-
-       \\
-        b----------------
-    ---0
-        \\
-         \\
-          \\     up to a range of ten (for round shot)
-           \\
-            \\
-             \\
-
-.fi
-An interesting phenomenon occurred when a broadside was fired
-down the length of an enemy ship.  The shot tended to bounce along
-the deck and did several times more damage.  This phenomenon was called
-a rake.  Because the bows of a ship are very strong and present a smaller
-target than the stern, a stern rake (firing from the stern to the bow) causes
-more damage than a bow rake.
-.nf
-
-                        b
-                       00   ----  Stern rake!
-                         a
-
-.fi
-Most ships were equipped with carronades, which were very large, close
-range cannons.  American ships from the revolution until the War of 1812
-were almost entirely armed with carronades.
-.PP
-The period of history covered in
-.I Sail
-is approximately from the 1770's until the end of Napoleonic France in 1815.
-There are many excellent books about the age of sail.  My favorite author
-is Captain Frederick Marryat.  More contemporary authors include C.S. Forester
-and Alexander Kent.
-.PP
-Fighting ships came in several sizes classed by armament.  The mainstays of
-any fleet were its "Ships of the Line", or "Line of Battle Ships".  They
-were so named because these ships fought together in great lines.  They were
-close enough for mutual support, yet every ship could fire both its broadsides.
-We get the modern words "ocean liner," or "liner," and "battleship" from
-"ship of the line."  The most common size was the 74 gun two decked
-ship of the line.  The two gun decks usually mounted 18 and 24 pounder guns.
-.PP
-The pride of the fleet were the first rates.  These were huge three decked
-ships of the line mounting 80 to 136 guns.  The guns in the three tiers
-were usually 18, 24, and 32 pounders in that order from top to bottom.
-.PP
-Various other ships came next.  They were almost all "razees," or ships
-of the line with one deck sawed off.  They mounted 40-64 guns and were
-a poor cross between a frigate and a line of battle ship.  They neither
-had the speed of the former nor the firepower of the latter.
-.PP
-Next came the "eyes of the fleet."  Frigates came in many sizes mounting
-anywhere from 32 to 44 guns.  They were very handy vessels.  They could
-outsail anything bigger and outshoot anything smaller.  Frigates didn't
-fight in lines of battle as the much bigger 74's did.  Instead, they
-harassed the enemy's rear or captured crippled ships.  They were much
-more useful in missions away from the fleet, such as cutting out expeditions
-or boat actions.  They could hit hard and get away fast.
-.PP
-Lastly, there were the corvettes, sloops, and brigs.  These were smaller
-ships mounting typically fewer than 20 guns.  A corvette was only slightly
-smaller than a frigate, so one might have up to 30 guns.  Sloops were used
-for carrying dispatches or passengers.  Brigs were something you built for
-land-locked lakes.
-.SH SAIL PARTICULARS
-Ships in
-.I Sail
-are represented by two characters.  One character represents the bow of
-the ship, and the other represents the stern.  Ships have nationalities
-and numbers.  The first ship of a nationality is number 0, the second
-number 1, etc.  Therefore, the first British ship in a game would be
-printed as "b0".  The second Brit would be "b1", and the fifth Don
-would be "s4".
-.PP
-Ships can set normal sails, called Battle Sails, or bend on extra canvas
-called Full Sails.  A ship under full sail is a beautiful sight indeed,
-and it can move much faster than a ship under Battle Sails.  The only
-trouble is, with full sails set, there is so much tension on sail and
-rigging that a well aimed round shot can burst a sail into ribbons where
-it would only cause a little hole in a loose sail.  For this reason,
-rigging damage is doubled on a ship with full sails set.  Don't let
-that discourage you from using full sails.  I like to keep them up
-right into the heat of battle.  A ship
-with full sails set has a capital letter for its nationality.  E.g.,
-a Frog, "f0", with full sails set would be printed as "F0".
-.PP
-When a ship is battered into a listing hulk, the last man aboard "strikes
-the colors."  This ceremony is the ship's formal surrender.  The nationality
-character
-of a surrendered ship is printed as "!".  E.g., the Frog of our last example
-would soon be "!0".
-.PP
-A ship has a random chance of catching fire or sinking when it reaches the
-stage of listing hulk.  A sinking ship has a "~" printed for its nationality,
-and a ship on fire and about to explode has a "#" printed.
-.PP
-Captured ships become the nationality of the prize crew.  Therefore, if
-an American ship captures a British ship, the British ship will have an
-"a" printed for its nationality.  In addition, the ship number is changed
-to "&","'", "(", ,")", "*", or "+" depending upon the original number,
-be it 0,1,2,3,4, or 5.  E.g., the "b0" captured by an American becomes the
-"a&".  The "s4" captured by a Frog becomes the "f*".
-.PP
-The ultimate example is, of course, an exploding Brit captured by an
-American: "#&".
-.SH MOVEMENT
-Movement is the most confusing part of
-.I Sail
-to many.  Ships can head in 8 directions:
-.nf
-
-                                 0      0      0
-        b       b       b0      b       b       b       0b      b
-        0        0                                             0
-
-.fi
-The stern of a ship moves when it turns.  The bow remains stationary.
-Ships can always turn, regardless of the wind (unless they are becalmed).
-All ships drift when they lose headway.  If a ship doesn't move forward
-at all for two turns, it will begin to drift.  If a ship has begun to
-drift, then it must move forward before it turns, if it plans to do
-more than make a right or left turn, which is always possible.
-.PP
-Movement commands to
-.I Sail
-are a string of forward moves and turns.  An example is "l3".  It will
-turn a ship left and then move it ahead 3 spaces.  In the drawing above,
-the "b0" made 7 successive left turns.  When
-.I Sail
-prompts you for a move, it prints three characters of import.  E.g.,
-.nf
-	move (7, 4):
-.fi
-The first number is the maximum number of moves you can make,
-including turns.  The second number is the maximum number of turns
-you can make.  Between the numbers is sometimes printed a quote "'".
-If the quote is present, it means that your ship has been drifting, and
-you must move ahead to regain headway before you turn (see note above).
-Some of the possible moves for the example above are as follows:
-.nf
-
-	move (7, 4): 7
-	move (7, 4): 1
-	move (7, 4): d		/* drift, or do nothing */
-	move (7, 4): 6r
-	move (7, 4): 5r1
-	move (7, 4): 4r1r
-	move (7, 4): l1r1r2
-	move (7, 4): 1r1r1r1
-
-.fi
-Because square riggers performed so poorly sailing into the wind, if at
-any point in a movement command you turn into the wind, the movement stops
-there.  E.g.,
-.nf
-
-	move (7, 4): l1l4
-	Movement Error;
-	Helm: l1l
-
-.fi
-Moreover, whenever you make a turn, your movement allowance drops to
-min(what's left, what you would have at the new attitude).  In short,
-if you turn closer to the wind, you most likely won't be able to sail the
-full allowance printed in the "move" prompt.
-.PP
-Old sailing captains had to keep an eye constantly on the wind.  Captains
-in
-.I Sail
-are no different.  A ship's ability to move depends on its attitude to the
-wind.  The best angle possible is to have the wind off your quarter, that is,
-just off the stern.  The direction rose on the side of the screen gives the
-possible movements for your ship at all positions to the wind.  Battle
-sail speeds are given first, and full sail speeds are given in parenthesis.
-.nf
-
-				 0 1(2)
-				\\|/
-				-^-3(6)
-				/|\\
-				 | 4(7)
-				3(6)
-
-.fi
-Pretend the bow of your ship (the "^") is pointing upward and the wind is
-blowing from the bottom to the top of the page.  The
-numbers at the bottom "3(6)" will be your speed under battle or full
-sails in such a situation.  If the wind is off your quarter, then you
-can move "4(7)".  If the wind is off your beam, "3(6)".  If the wind is
-off your bow, then you can only move "1(2)".  Facing into the wind, you
-can't move at all.  Ships facing into the wind were said to be "in irons".
-.SH WINDSPEED AND DIRECTION
-The windspeed and direction is displayed as a little weather vane on the
-side of the screen.  The number in the middle of the vane indicates the wind
-speed, and the + to - indicates the wind direction.  The wind blows from
-the + sign (high pressure) to the - sign (low pressure).  E.g.,
-.nf
-
-				|
-				3
-				+
-
-.fi
-.PP
-The wind speeds are 0 = becalmed, 1 = light breeze, 2 = moderate breeze,
-3 = fresh breeze, 4 = strong breeze, 5 = gale, 6 = full gale, 7 = hurricane.
-If a hurricane shows up, all ships are destroyed.
-.SH GRAPPLING AND FOULING
-If two ships collide, they run the risk of becoming tangled together.  This
-is called "fouling."  Fouled ships are stuck together, and neither can move.
-They can unfoul each other if they want to.  Boarding parties can only be
-sent across to ships when the antagonists are either fouled or grappled.
-.PP
-Ships can grapple each other by throwing grapnels into the rigging of
-the other.
-.PP
-The number of fouls and grapples you have are displayed on the upper
-right of the screen.
-.SH BOARDING
-Boarding was a very costly venture in terms of human life.  Boarding parties
-may be formed in
-.I Sail
-to either board an enemy ship or to defend your own ship against attack.
-Men organized as Defensive Boarding Parties fight twice as hard to save
-their ship as men left unorganized.
-.PP
-The boarding strength of a crew depends upon its quality and upon the
-number of men sent.
-.SH CREW QUALITY
-The British seaman was world renowned for his sailing abilities.  American
-sailors, however, were actually the best seamen in the world.  Because the
-American Navy offered twice the wages of the Royal Navy, British seamen
-who liked the sea defected to America by the thousands.
-.PP
-In
-.I Sail,
-crew quality is quantized into 5 energy levels.  "Elite" crews can outshoot
-and outfight all other sailors.  "Crack" crews are next.  "Mundane" crews
-are average, and "Green" and "Mutinous" crews are below average.  A good
-rule of thumb is that "Crack" or "Elite" crews get one extra hit
-per broadside compared to "Mundane" crews.  Don't expect too much from
-"Green" crews.
-.SH BROADSIDES
-Your two broadsides may be loaded with four kinds of shot: grape, chain,
-round, and double.  You have guns and carronades in both the port and starboard
-batteries.  Carronades only have a range of two, so you have to get in
-close to be able to fire them.  You have the choice of firing at the hull
-or rigging of another ship.  If the range of the ship is greater than 6,
-then you may only shoot at the rigging.
-.PP
-The types of shot and their advantages are:
-.SH ROUND
-Range of 10.  Good for hull or rigging hits.
-.SH DOUBLE
-Range of 1.  Extra good for hull or rigging hits.
-Double takes two turns to load.
-.SH CHAIN
-Range of 3.  Excellent for tearing down rigging.
-Cannot damage hull or guns, though.
-.SH GRAPE
-Range of 1.  Sometimes devastating against enemy crews.
-.PP
-On the side of the screen is displayed some vital information about your
-ship:
-.nf
-
-			Load  D! R!
-			Hull  9
-			Crew  4  4  2
-			Guns  4  4
-			Carr  2  2
-			Rigg  5 5 5 5

-.fi
-"Load" shows what your port (left) and starboard (right) broadsides are
-loaded with.  A "!" after the type of shot indicates that it is an initial
-broadside.  Initial broadside were loaded with care before battle and before
-the decks ran red with blood.  As a consequence, initial broadsides are a
-little more effective than broadsides loaded later.  A "*" after the type of
-shot indicates that the gun
-crews are still loading it, and you cannot fire yet.  "Hull" shows how much
-hull you have left.  "Crew" shows your three sections of crew.  As your
-crew dies off, your ability to fire decreases.  "Guns" and "Carr" show
-your port and starboard guns.  As you lose guns, your ability to fire
-decreases.  "Rigg" shows how much rigging you have on your 3 or 4 masts.
-As rigging is shot away, you lose mobility.
-.SH EFFECTIVENESS OF FIRE
-It is very dramatic when a ship fires its thunderous broadsides, but the
-mere opportunity to fire them does not guarantee any hits.  Many factors
-influence the destructive force of a broadside.  First of all, and the chief
-factor, is distance.  It is harder to hit a ship at range ten than it is
-to hit one sloshing alongside.  Next is raking.  Raking fire, as
-mentioned before,
-can sometimes dismast a ship at range ten.  Next, crew size and quality affects
-the damage done by a broadside.   The number of guns firing also bears on the
-point,
-so to speak.  Lastly, weather affects the accuracy of a broadside.  If the
-seas are high (5 or 6), then the lower gunports of ships of the line can't
-even be opened to run out the guns.  This gives frigates and other flush
-decked vessels an advantage in a storm.  The scenario
-.I Pellew vs. The Droits de L'Homme
-takes advantage of this peculiar circumstance.
-.SH REPAIRS
-Repairs may be made to your Hull, Guns, and Rigging at the slow rate of
-two points per three turns.  The message "Repairs Completed" will be
-printed if no more repairs can be made.
-.SH PECULIARITIES OF COMPUTER SHIPS
-Computer ships in
-.I Sail
-follow all the rules above with a few exceptions.  Computer ships never
-repair damage.  If they did, the players could never beat them.  They
-play well enough as it is.  As a consolation, the computer ships can fire double
-shot every turn.  That fluke is a good reason to keep your distance.  The
-.I
-Driver
-figures out the moves of the computer ships.   It computes them with a typical
-A.I. distance function and a depth first search to find the maximum "score."
-It seems to work fairly well, although I'll be the first to admit it isn't
-perfect.
-.SH HOW TO PLAY
-Commands are given to
-.I Sail
