+\maketitle
+\begin{abstract}
+\textit{The Feebs War} is a modified version of Planet of the Feebs
+\url{http://www.cliki.net/}, a game made for people learn and improve
+their lisp and code manipulation tecniques. The graphics are now displayed
+using PAL \url{http://common-lisp.net/project/pal/}'s libraries,
+so the problems with portability from CMUCL and X Window Sistem do
+not exist anymore. Also the code is cleaner and simpler both to make
+a feeb and to read the code.
+\end{abstract}
+\tableofcontents{}
+
+
+\section{Introduction}
+
+The Feebs are intelligent and hostile creatures that live inside maze
+tunnels. They also have no mercy with each other, so they frequently
+throw a letal flame from through their mouth, and, after that, they
+can eat the carcass left. But throwing flames have an energy cost,
+so they must keep tracking for food.
+
+This game is intended to help lisp newbies (or maybe a little more
+advanced lispers) to learn lisp. A player must create a function that
+receives what his/her feeb is seeing and feeling, and returns what
+it will do next. To create the better feeb, one can create variables
+to store data from previous moves (or not), and can also use all the
+power of lisp to improve his/her creature.
+
+
+\subsection{Changes from \emph{Planet of the Feebs}}
+
+Many changes were made from the original game, but, if you have any
+feeb definition and you want to use it, it should be easy to adapt
+the brain function to the new rules.
+
+The main reason of this project is that \textit{Planet of the Feebs}
+is really interesting for (not just) newbies to learn lisp, but the
+difficulties to install, unportability and the ausence of competitors
+make it difficult to someone to be interested in making a feeb. So,
+I hope that making these adjustments and maybe creating some contests
+over the web make people be more interested in learning lisp.
+
+So, these are (some of) the changes:
+
+\begin{itemize}
+\item The graphics are not based on X Window Sistem anymore, but on PAL,
+and there are no CMUCL's event handler. This way, the code is more
+portable and graphics can be improved without those hundreds of lines
+that the original version has. Just creating some .bmp or .jpg files
+of a feeb and your feeb is much more personalized!
+\item Every element of the map (except walls) is a list, so the brain of
+a feeb doesn't need to test all the time if the element is an atom
+or a list (wich, in my opinion, is really boring, unlispy and unnecessary
+in this case). That was only a reason to duplicate code and work,
+adding no results at all...
+\item Many functions and variables are changed and others were added.
+\item Someone watching the game can control a Feeb with the keyboard, if
+he/she wants to, and say when the game must finish.
+\item This document is more objective than the one provided with \textit{Planet
+of the Feebs}, and is fully compatible with the code. This way it
+is easier to search for some information.
+\end{itemize}
+
+\section{The Game}
+
+
+\subsection{Overview}
+
+Your feeb's objective is to survive and kill other feebs. It is inside
+a maze of tunnels. Every turn, all feebs lose one unit of energy,
+and maybe starves. Your feeb is able to move forward, turn left, right
+or around, flame, peek around a corner, eat something or just wait.
+After all feebs move, the flames thrown before also move (or dissipate),
+carcasses may rot and mushrooms may grow, accordingly to some rules.
+
+To see what values are taken, one can use \textsf{\textbf{(list-parameter-settings)}}.
+Using \textsf{\textbf{setf}} gives the possibility to change them
+and \textsf{\textbf{documentation}} can be used to know them. Just
+remember that every probability must be a rational number (like 1/2).
+These parameters are just for one to know how the game is going to
+be, but in the begining there is no need to explicitly use them when
+creating the brain of a feeb.
+
+These are some global parameters:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{{*}game-length{*}}}}] Number of turns the game
+will last, or nil if there is a human player.
+\item [{\textsf{\textbf{{*}points-for-killing{*}}}}] How many points some
+feeb earn for killing someone.
+\item [{\textsf{\textbf{{*}points-for-dying{*}}}}] How many points some
+feeb earn for dying (usually negative).
+\item [{\textsf{\textbf{{*}maze-x-size{*}}}}] Horizontal size of the maze.
+\item [{\textsf{\textbf{{*}maze-y-size{*}}}}] Vertical size of the maze.
+\item [{\textsf{\textbf{(get-maze-map)}}}] This command can be used to
+get the map (see section \ref{sub:Map}).
+\end{lyxlist}
+
+\subsection{Throwing flame}
+
+If a feeb decides to throw a flame, and if it is prepared to, it will
+spend energy, and the next turn there will be a flame in the square
+in front of the feeb. For a few turns, the feeb will not be able to
+throw flames. The turn after the feeb throws the flame, it is able
+to see its own flame exactly in front of it, so it shouldn't move
+forward. Each turn, the flame moves forward destroing mushrooms and
+killing feebs it encounters, transforming them into carcass. If there
+is a wall, the flame can reflect, and will turn 180 degrees.
+
+Once a feeb is killed, in it's place in the maze there will appear
+a carcass. The feeb goes to the end of the killed feebs line. Whenever
+a carcass rots, the first feeb in line will reincarnate. So, dying
+is not so terrible.
+
+These are the parameters related to flames:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{{*}flame-energy{*}}}}] Amount of energy lost after
+throwing a flame.
+\item [{\textsf{\textbf{{*}fireball-guaranteed-lifetime{*}}}}] Number of
+turns that a fireball is guaranteed not to dissipate, unless it encounters
+a wall.
+\item [{\textsf{\textbf{{*}fireball-dissipation-probability{*}}}}] Probability
+of the flame to dissipate each turn after the apropriate time.
+\item [{\textsf{\textbf{{*}fireball-reflection-probability{*}}}}] Probability
+of the flame to reflect when encountering a wall.
+\item [{\textsf{\textbf{{*}flame-no-recovery-time{*}}}}] Number of turns
+that a feeb cannot fire.
+\item [{\textsf{\textbf{{*}flame-recovery-probability{*}}}}] Probability
+of the feeb to recover the hability to throw a flame, after the apropriate
+time.
+\end{lyxlist}
+
+\subsection{Eating food}
+
+There are two kinds of food, carcasses and mushrooms. Carcasses usually
+give less energy than mushrooms, and may rot, but, while it does not
+rot, a feeb can feed as long as it wishes. By eating food, the feeb
+will be able to recover energy, wich is important because, if a feeb
+stays with 0 or less units of energy, it starves.
+
+These are the quantities:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{{*}mushroom-energy{*}}}}] Amount of energy recovered
+when the feeb eats a mushroom.
+\item [{\textsf{\textbf{{*}carcass-energy{*}}}}] Amount of energy recovered
+each turn that the feeb eats a carcass.
+\item [{\textsf{\textbf{{*}carcass-guaranteed-lifetime{*}}}}] Number of
+turns that a carcass will surely stay there. After these turns, it
+can rot, depending on probabilities.
+\item [{\textsf{\textbf{{*}carcass-rot-probability{*}}}}] Probability of
+the carcass to rot, after the apropriate time.
+\item [{\textsf{\textbf{{*}maximum-energy{*}}}}] Maximum amount of energy
+that a feeb can have eating.
+\item [{\textsf{\textbf{{*}starting-energy{*}}}}] Amount of energy a feeb
+has when it reincarnates.
+\item [{\textsf{\textbf{{*}number-of-mushrooms{*}}}}] Quantity of mushrooms
+that exist in the maze.
+\end{lyxlist}
+
+\section{The Feeb}
+
+A feeb needs four things: a name, a brain, an initialize function
+(optional) and a set of graphics (optional).
+
+\begin{itemize}
+\item The name, a string.
+\item The brain is a function that decides what the feeb will do next, based
+on what it is seeing and feeling.
+\item The initializer is invoked when the game is about to start, so it
+can analyze the map, global parameters, and so on.
+\item The set of graphics is an image file (of format BMP, JPEG, PNG, and
+any others that supported by SDL\_image).
+\end{itemize}
+One can create a feeb calling \textsf{\textbf{(define-feeb~}}\textsf{name~brain~}\textsf{\textbf{:initializer}}\textsf{~prepare~}\textsf{\textbf{:graphics}}\textsf{~graphics}\textsf{\textbf{)}}.
+If name is already used, a warning will be signaled, and the old feeb
+will be substituted. Calling \textsf{\textbf{(list-of-feebs)}} will
+return the list of the feebs (names only) that will be defined when
+the game begins. \textsf{\textbf{(delete-feeb}}\textsf{~name}\textsf{\textbf{)}}
+will delete the feeb with this name from this list, and \textsf{\textbf{(delete-all-feebs)}}
+will clear it.
+
+
+\subsection{Possible decisions}
+
+After processing the information available, the brain will take a
+decision. If this decision is not one of the decisions listed down,
+a warning will be signaled, and the result will be like \textsf{\textbf{:wait}}.
+Then, if someone are testing a brain function, he or she will be able
+to know if something goes wrong.
+
+The possible values that the brain function can return are these:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{:move-forward}}}] Move one square forward, unless
+there is a wall in front of the feeb.
+\item [{\textsf{\textbf{:turn-left}}}] Turn 90 degrees to the left.
+\item [{\textsf{\textbf{:turn-right}}}] Turn 90 degrees to the right.
+\item [{\textsf{\textbf{:turn-around}}}] Turn 180 degrees.
+\item [{\textsf{\textbf{:flame}}}] Throw a flame. The flame will be created
+next turn in the front square of the feeb.
+\item [{\textsf{\textbf{:wait}}}] Do nothing in this turn.
+\item [{\textsf{\textbf{:peek-left}}}] Peek to the left around a corner.
+The creature does note actually move, but, in the next turn, the creature
+will have the same vision that it would have if he had moved one step
+foward and turned left. This is used so a feeb can analize a corridor
+before trespassing it.
+\item [{\textsf{\textbf{:peek-right}}}] Peek to the right around a corner,
+analogous of \textsf{\textbf{:peek-left}}.
+\item [{\textsf{\textbf{:eat-carcass}}}] Eat a carcass if there is any
+available in the feeb's square. The amount of \textsf{\textbf{{*}carcass-energy{*}}}
+is restored to the feeb's energy.
+\item [{\textsf{\textbf{:eat-mushroom}}}] Eat a mushroom if there is any
+available in the feeb's square. The amount of \textsf{\textbf{{*}mushroom-energy{*}}}
+is restored to the feeb's energy.
+\end{lyxlist}
+
+\subsection{Information available}
+
+The brain of a feeb mus take five arguments; I'll call them \textsf{\emph{status}},
+\textsf{\emph{proximity}}, \textsf{\emph{vision}}, \textsf{\emph{vision-left}}
+and \textsf{\emph{vision-right}}.
+
+
+\subsubsection{Status}
+
+Every time the brain is called, it receives some useful information
+through \textsf{\textbf{status}}.
+
+The structure \textsf{\textbf{status}} keeps information about the
+feeb itself. Also it has information of the previous movement of the
+feeb. To access them, one must call:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{(name}}\textsf{\emph{~status}}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+name of the feeb.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(facing~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+Where
+the feeb is facing, one of the constants provided: \textsf{\textbf{north}},
+\textsf{\textbf{south}}, \textsf{\textbf{east}} or \textsf{\textbf{west}},
+wich are 0, 1, 2 and 3 respectivelly.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(x-position~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+horizontal position of the feeb, increasing to east. If \textsf{\textbf{{*}sense-location{*}}}
+is nil, it returns nil instead.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(y-position~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+vertical position of the feeb, increasing to north. If \textsf{\textbf{{*}sense-location{*}}}
+is nil, it returns nil instead.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(peeking~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+If
+it is \textsf{\textbf{:left}} or \textsf{\textbf{:right}}, it means
+that the current \textsf{\emph{vision}} provided is result of a previous
+\textsf{\textbf{:peek-left}} or \textsf{\textbf{:peek-right}} command
+of the same feeb. Otherwise, it is \textsf{\textbf{nil}}.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(line-of-sight~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+Indicates
+the amount of valid entries in \textsf{\emph{vision}}. It actually
+means that \textsf{\textbf{(aref~}}\textsf{\emph{vision~}}\textsf{\textbf{(line-of-sight~}}\textsf{\emph{status}}\textsf{\textbf{))}}
+will return \textsf{\textbf{:rock}}.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(ready-to-fire~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+\textsf{\textbf{T}}
+indicates that the feeb is ready to fire. \textsf{\textbf{Nil}} indicates
+it is not.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(aborted}}\textsf{\emph{~status}}\textsf{\textbf{)}}}] \begin{flushleft}
+Related
+with timing. Returns \textsf{\textbf{T}} if the last move of feeb
+was aborted because of speed.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(last-move~}}\textsf{\emph{status}}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+feeb's previous move, or \textsf{\textbf{:dead}} if it has just reincarnated.
+\par\end{flushleft}
+\end{lyxlist}
+
+\subsubsection{Proximity and vision}
+
+The brain receives also information about what is near the feeb and
+what the feeb sees.
+
+The structure \textsf{\emph{proximity}} has the contents of the squares
+near the feeb, with these fields:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{(my-square~}}\textsf{\emph{proximity}}\textsf{\textbf{)}}}] \begin{flushleft}
+Contents
+of the feeb's current square.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(left-square~}}\textsf{\emph{proximity}}\textsf{\textbf{)}}}] \begin{flushleft}
+Contents
+of the right square of the feeb.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(right-square~}}\textsf{\emph{proximity}}\textsf{\textbf{)}}}] \begin{flushleft}
+Contents
+of the left square of the feeb.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(rear-square}}\textsf{\emph{~proximity}}\textsf{\textbf{)}}}] \begin{flushleft}
+Contents
+of the square behind the feeb.
+\par\end{flushleft}
+\item [{The}] vector \textsf{\emph{vision}} has the contents of the squares
+that are in front of the feeb. For example, \textsf{\textbf{(aref~}}\textsf{\emph{vision~}}\textsf{0}\textsf{\textbf{)}}
+will return the contents of the square in front of the feeb, \textsf{\textbf{(aref~}}\textsf{\emph{vision~}}\textsf{1}\textsf{\textbf{)}}
+will return the contents of the next square, and so on. As said before,
+\textsf{\textbf{(aref~}}\textsf{\emph{vision~}}\textsf{\textbf{(line-of-sight~}}\textsf{\emph{status}}\textsf{\textbf{))}}
+will be the first :rock encountered. All subsequents square, like
+\textsf{\textbf{(aref~}}\textsf{\emph{vision~}}\textsf{\textbf{(+~}}\textsf{1~}\textsf{\textbf{(line-of-sight~}}\textsf{\emph{status}}\textsf{\textbf{)))}},
+will be garbage and should not be used.
+\end{lyxlist}
+The contents of one square returned by any of these calls is either
+:rock or a list of elements, or maybe \textsf{\textbf{nil}} if the
+square is empty. Each element of the square is one of these:
+
+\begin{itemize}
+\item \textbf{Feeb image.} One can call \textsf{\textbf{(feeb-image-p~}}\textsf{element}\textsf{\textbf{)}}
+to see if element is a feeb image.
+\item \textbf{Fireball image.} One can call \textsf{\textbf{(fireball-image-p~}}\textsf{element}\textsf{\textbf{)}}
+to check if element is a fireball image.
+\item \textsf{\textbf{:carcass}}. If there is a \textsf{\textbf{:carcass}}
+in the square of the feeb (i.e. in \textsf{\textbf{(my-square~}}\textsf{\emph{proximity}}\textsf{\textbf{)}}),
+the call \textsf{\textbf{:eat-carcass}} will make the feeb eat it.
+\item \textsf{\textbf{:mushroom}}. Analogous to \textsf{\textbf{:carcass}}.
+A mushroom appears randomly in places (mushroom patchs) previouly
+marked in the map.
+\end{itemize}
+
+\subsubsection{Feebs and fireballs images}
+
+Both fireballs and feebs that are given to the brain function are
+not the real ones, but just images with contents that the brain function
+can access.
+
+These are the fields available:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{(feeb-image-name}}\textsf{~feeb-image}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+name of the feeb. Maybe you can know it's weakpoints.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(feeb-image-facing~}}\textsf{feeb-image}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+facing of the feeb. This way the brain function can see if the feeb-image
+either sees it or not.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(feeb-image-peeking~}}\textsf{feeb-image}\textsf{\textbf{)}}}] \begin{flushleft}
+Returns
+\textsf{\textbf{:peek-left}} or \textsf{\textbf{:peek-right}} if the
+feeb is peeking to (its) left or right, or \textsf{\textbf{nil}} if
+not.
+\par\end{flushleft}
+\item [{\textsf{\textbf{(fireball-image-direction~}}\textsf{fireball-image}\textsf{\textbf{)}}}] \begin{flushleft}
+The
+direction that the fireball image is going to.
+\par\end{flushleft}
+\end{lyxlist}
+
+\subsubsection{Vision-left and vision-right}
+
+\textsf{\emph{vision-left}} and \textsf{\emph{vision-right}} are vectors
+similar to vision, but they are less precise in the contents. Also
+their valid contents are limited by \textsf{\textbf{(line-of-sight~}}\textsf{\emph{status}}\textsf{\textbf{)}},
+so \textsf{\textbf{(aref~}}\textsf{\emph{vision-left~}}\textsf{\textbf{(line-of-sight~}}\textsf{\emph{status}}\textsf{\textbf{))}},
+for example, will return \textsf{\textbf{:unknown}}.
+
+Note that feebs that are not peeking, mushrooms and carcasses are
+\emph{not} be detected by these vectors. Also, if there is a feeb
+peeking to the opposite side, it won't be detected either. These are
+the possible returns of the elements in \textsf{\textbf{vision-left}}
+and \textsf{\textbf{vision-right}}:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{:peek-letf}}}] This means that in that square there
+is a feeb peeking to (its) left.
+\item [{\textsf{\textbf{:peek-right}}}] This means that in that square
+there is a feeb peeking to (its) right.
+\item [{\textsf{\textbf{nil}}}] This square is empty.
+\item [{\textsf{\textbf{:rock}}}] This square is just a wall.
+\end{lyxlist}
+
+\subsection{Extra functions provided}
+
+Before making the brain of your feeb, you might want to take a look
+at the Extra functions that are available at the end of the feebs.lisp
+file. The only thing you need so you can use them is to see their
+code and know what they do.
+
+
+\subsection{Graphics}
+
+With this version of the game, it's possible to choose the graphics
+of a feeb when creating it, so your feeb will be more personalized.
+
+The graphic of a feeb is defined by an image file, which should have
+three colunms by eight lines of pictures of the same size. The four
+first lines must be the animations of the feeb walking up, left, down
+and right, respectively. The next four lines must be the pictures
+of the feeb flaming up, left, down and right, respectively. To see
+an example, see {}``default-feeb.png''.
+
+After creating the image file, you must call \textsf{\textbf{(create-graphics}}\textsf{~path-to-image-file}\textsf{\textbf{)}}.
+If you now how to work with sdl surfaces in lispbuilder, you may use
+the function with a surface instead of a image file; or you can call
+\textsf{\textbf{(create-graphics~}}\textsf{path-to-image-file~nil}\textsf{\textbf{)}}
+if the surface should not be freed after the call. The result must
+be the third argument given to define-feeb.
+
+
+\subsection{Starting the game}
+
+The game loop is started by calling (feebs).
+
+
+\section{Contests}
+
+I sugest that you see this chapter only after you have created at
+least a basic brain feeb, wich is better than the (simple) provided
+brain, and when you want to participate of a contest or a game with
+your friends.
+
+
+\subsection{\label{sub:Map}Map}
+
+It is possible to get the maze map during the game, but with only
+the corridors. Note that the function that gets the map is purposely
+a little slow, so, invoking it too many times in a contest that uses
+timing atributes is not a good idea; anyway, it is possible to invoke
+this function before defining the feeb, and store its value somewhere.
+Also note that the map returned does not have any information about
+what is really in the maze, but only the possible ways.
+
+To get the map, one can call \textsf{\textbf{(get-maze-map)}}. This
+function will return \textsf{\textbf{nil}} if \textsf{\textbf{{*}may-get-maze-p{*}}}
+is also \textsf{\textbf{nil}}. Otherwise, the map returned is an array,
+so that calling \textsf{\textbf{(aref}}\textsf{~map~x~y}\textsf{\textbf{)}}
+will get the contents in the euclidean position (x,y) . The contents
+of a cell could be one of these:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{:mushroom-place}}}] A mushroom patch, i.e. when
+a mushroom is eaten it can come out here.
+\item [{\textsf{\textbf{:feeb-entry-place}}}] A feeb entry, i.e. if a carcass
+rots a feeb can appear here.
+\item [{\textsf{\textbf{:rock}}}] A wall. Feebs cannot come in this place.
+\item [{\textsf{\textbf{nil}}}] An {}``empty'' place, i.e. neither of
+the previous.
+\end{lyxlist}
+
+\subsection{Timing}
+
+There are also some timing atributes that can be given to the game.
+If the feeb takes too long to make a decision, there is more probability
+of its command to be aborted.
+
+To make this available, someone must set these:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{{*}slow-feeb-noop-switch{*}}}}] If is non-nil,
+there is a possibility that the move of a feeb is aborted according
+to its function time. Not applied to the human controlled feeb.
+\item [{\textsf{\textbf{{*}slow-feeb-noop-factor{*}}}}] The probability
+of the feeb to abort will be this factor times the amount of time
+the feeb takes to have a decision, divided for the total time taken
+by all the feebs in the current turn.
+\end{lyxlist}
+
+\subsection{Sense of location}
+
+Some accessors related to position and orientation of the feeb can
+be turned off.
+
+These are the parameters:
+
+\begin{lyxlist}{00.00.0000}
+\item [{\textsf{\textbf{{*}sense-location-p{*}}}}] Tells if the actual
+position of the feeb can be determinated accessing \textsf{\textbf{x-position}}
+and \textsf{\textbf{y-position}}.
+\end{lyxlist}
+
+\subsection{Changing the rules}
+
+To change the rules of the contest, they must be changed before the
+feebs are defined, because in a feeb definition it could use the values
+of the variables to make a global strategy, and change the strategies
+after this could not be fair.
+
+All the parameters that can be listed using \textsf{\textbf{(list-parameter-settings)}}
+can be changed using setf. Also, they all have documentation about
+themselves, so feel free to use \textsf{\textbf{(documentation~}}\textsf{parameter~'variable}\textsf{\textbf{)}}
+and see what each parameter does. Documentation is available to external
+functions too.
+
+It is possible to change the layout of the map by calling \textsf{\textbf{(change-layout}}\textsf{~new-layout}\textsf{\textbf{)}}.
+There are a few predefined mazes that are \textsf{\textbf{{*}maze-0{*}}}
+throw \textsf{\textbf{{*}maze-5{*}}}. If you want to create a new
+map, take the template (commented) inside the same file, or create
+maybe a bigger template (of any size, because the values of \textsf{\textbf{{*}maze-x-size{*}}}
+and \textsf{\textbf{{*}maze-y-size{*}}} will be changed accordingly).

+With this version of the game, it's possible to choose the graphics
+of a feeb when creating it, so your feeb will be more personalized.
+
+<P>
+The graphic of a feeb is defined by an image file, which should have
+three colunms by eight lines of pictures of the same size. The four
+first lines must be the animations of the feeb walking up, left, down
+and right, respectively. The next four lines must be the pictures
+of the feeb flaming up, left, down and right, respectively. To see
+an example, see ``default-feeb.png''.
+
+<P>
+After creating the image file, you must call <I><B>(create-graphics</B></I><I> path-to-image-file</I><I><B>)</B></I>.
+If you now how to work with sdl surfaces in lispbuilder, you may use
+the function with a surface instead of a image file; or you can call
+<I><B>(create-graphics </B></I><I>path-to-image-file nil</I><I><B>)</B></I>
+if the surface should not be freed after the call. The result must
+be the third argument given to define-feeb.

+</H2>
+
+<P>
+It is possible to get the maze map during the game, but with only
+the corridors. Note that the function that gets the map is purposely
+a little slow, so, invoking it too many times in a contest that uses
+timing atributes is not a good idea; anyway, it is possible to invoke
+this function before defining the feeb, and store its value somewhere.
+Also note that the map returned does not have any information about
+what is really in the maze, but only the possible ways.
+
+<P>
+To get the map, one can call <I><B>(get-maze-map)</B></I>. This
+function will return <I><B>nil</B></I> if <I><B>*may-get-maze-p*</B></I>
+is also <I><B>nil</B></I>. Otherwise, the map returned is an array,
+so that calling <I><B>(aref</B></I><I> map x y</I><I><B>)</B></I>
+will get the contents in the euclidean position (x,y) . The contents
+of a cell could be one of these:
+
+<P>
+
+<UL>
+<LI>[<I><B>:mushroom-place</B></I>] A mushroom patch, i.e. when
+a mushroom is eaten it can come out here.
+</LI>
+<LI>[<I><B>:feeb-entry-place</B></I>] A feeb entry, i.e. if a carcass
+rots a feeb can appear here.
+</LI>
+<LI>[<I><B>:rock</B></I>] A wall. Feebs cannot come in this place.
+</LI>
+<LI>[<I><B>nil</B></I>] An ``empty'' place, i.e. neither of
+the previous.

+
+<P>
+The Feebs are intelligent and hostile creatures that live inside maze
+tunnels. They also have no mercy with each other, so they frequently
+throw a letal flame from through their mouth, and, after that, they
+can eat the carcass left. But throwing flames have an energy cost,
+so they must keep tracking for food.
+
+<P>
+This game is intended to help lisp newbies (or maybe a little more
+advanced lispers) to learn lisp. A player must create a function that
+receives what his/her feeb is seeing and feeling, and returns what
+it will do next. To create the better feeb, one can create variables
+to store data from previous moves (or not), and can also use all the
+power of lisp to improve his/her creature.

+To change the rules of the contest, they must be changed before the

+Changes from <I>Planet of the Feebs</I></A>
+</H2>
+
+<P>
+Many changes were made from the original game, but, if you have any
+feeb definition and you want to use it, it should be easy to adapt
+the brain function to the new rules.
+
+<P>
+The main reason of this project is that <I>Planet of the Feebs</I>
+is really interesting for (not just) newbies to learn lisp, but the
+difficulties to install, unportability and the ausence of competitors
+make it difficult to someone to be interested in making a feeb. So,
+I hope that making these adjustments and maybe creating some contests
+over the web make people be more interested in learning lisp.
+
+<P>
+So, these are (some of) the changes:
+
+<P>
+
+<UL>
+<LI>The graphics are not based on X Window Sistem anymore, but on PAL,
+and there are no CMUCL's event handler. This way, the code is more
+portable and graphics can be improved without those hundreds of lines
+that the original version has. Just creating some .bmp or .jpg files
+of a feeb and your feeb is much more personalized!
+</LI>
+<LI>Every element of the map (except walls) is a list, so the brain of
+a feeb doesn't need to test all the time if the element is an atom
+or a list (wich, in my opinion, is really boring, unlispy and unnecessary
+in this case). That was only a reason to duplicate code and work,
+adding no results at all...
+</LI>
+<LI>Many functions and variables are changed and others were added.
+</LI>
+<LI>Someone watching the game can control a Feeb with the keyboard, if
+he/she wants to, and say when the game must finish.
+</LI>
+<LI>This document is more objective than the one provided with <I>Planet
+of the Feebs</I>, and is fully compatible with the code. This way it
+is easier to search for some information.
+</LI>
+</UL>
+

+Your feeb's objective is to survive and kill other feebs. It is inside
+a maze of tunnels. Every turn, all feebs lose one unit of energy,
+and maybe starves. Your feeb is able to move forward, turn left, right
+or around, flame, peek around a corner, eat something or just wait.
+After all feebs move, the flames thrown before also move (or dissipate),
+carcasses may rot and mushrooms may grow, accordingly to some rules.
+
+<P>
+To see what values are taken, one can use <I><B>(list-parameter-settings)</B></I>.
+Using <I><B>setf</B></I> gives the possibility to change them
+and <I><B>documentation</B></I> can be used to know them. Just
+remember that every probability must be a rational number (like 1/2).
+These parameters are just for one to know how the game is going to
+be, but in the begining there is no need to explicitly use them when
+creating the brain of a feeb.
+

+If a feeb decides to throw a flame, and if it is prepared to, it will
+spend energy, and the next turn there will be a flame in the square
+in front of the feeb. For a few turns, the feeb will not be able to
+throw flames. The turn after the feeb throws the flame, it is able
+to see its own flame exactly in front of it, so it shouldn't move
+forward. Each turn, the flame moves forward destroing mushrooms and
+killing feebs it encounters, transforming them into carcass. If there
+is a wall, the flame can reflect, and will turn 180 degrees.

+
+ The licenses for most software and other practical works are designed

+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.

+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.

+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
