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). + + +\section{Reference} + +\begin{quote} +Fahlman, S.

We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +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.

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 +into proprietary programs.
