   This is a list of Frequently Asked Questions asked about LPMuds and
   the newsgroup devoted to them, rec.games.mud.lp. This FAQ is posted
   twice a month to rec.games.mud.lp, rec.games.mud.announce,
   news.answers, and rec.answers. All readers are strongly advised to
   read this FAQ before posting questions to the LPMud news group, as
   your question may already be answered in here.
   
   This FAQ is not intended to be a substitute for the general 3 part mud
   FAQ's. I strongly recommend people new to muds read those first. This
   FAQ deals with a particular class of muds known as LPMuds, and
   therefore does not even attempt to cover information important to
   other classes of muds.
     _________________________________________________________________
                                      
   The LPMud FAQ is divided into four sections:
   
   * Section I: Introduction
          
   * Section II: Playing LPMuds
          
   * Section III: Coding on an LPMud
          
   * Section IV: Starting Your Own LPMud

    What sort of posts belong in rec.games.mud.lp?
    
   From the rec.games.mud.lp charter of 23 October 1991:
   
   _"The charter of this newsgroup is to discuss topics related to the
   LPMUD variant of MUD. LPMUD is a particular "brand" of MUD that was
   written by Lars Penji and has gained some populatity among MUD players
   in general, Discussions here should be confined to the following
   topics. Briefly, LPMUD uses a "parser" to interpret a 'C' like
   language (called LPC) which defines the actual game being played. Thus
   the various topics of discussion break down like so:
     * Player and 'Wizard' issues
     * Ongoing LPMUD campaigns
     * Parser programming issues and bug fixes
     * LPC (LP 'C" code) programming
     * LPC source code posting
     * LPMUD administrativia and announcements
       
   Topics of discussion which should NOT include this newsgroup are:
     * "LPMUD is (better,worse) than..." flames
     * Non-LPMUD campaigns
     * Non-LPMUD issues or programming"
       
   _Specifically, rec.games.mud.lp supports _almost_ anything dealing
   with LPMuds. The primary rule is that the topic of your posts must
   someway affect the LPMud community. We do not care about Dikus and
   MOOs and so on. They may be very nice servers, but if we wanted to be
   reading about them, we would be reading rec.games.mud.diku and so on.
   
   Beyond that, the charter is a little unclear and out of date. What
   sort of LPMud related posts belong in the newsgroup generally falls
   into anything of general interest to the LPMud community in general or
   one-time administrative announcements for specific muds. This would
   include announcements of downtime, but exclude queries into why a
   particular mud is down.
   
   In particular, the following questions are definitely _not_ welcome in
   rec.games.mud.lp:
   
   * FascistMUD's admins are such jerks!!! They ...
          Why would you post this? I guarantee you will accomplish
          nothing by this. First of all, ALL mud admins have bad days
          where they may do something very unfair. It is the nature of
          things. So you may be the unfortunate victim of a rare set of
          circumstances rather than of a mean admin. Secondly, even if
          the mud admin is a jerk, no one on this newsgroup cares. People
          will play such muds either because the admin is damn good at
          creating a game or because the players are other jerks who like
          the atmosphere of lawlessness. Players like you may login from
          time to time, but eventually they will figure it out.
          
   * Do not post mudsex sessions
          An individual's sexual activities are not matters for public
          derision. How people choose to express themselves sexually is a
          private issue as long as only consenting adults are involved.
          
   * Where is CheeseMUD? I have not been able to connect all day!
          If it is going to be down a long time, the admins should post
          to rec.games.mud.announce. Otherwise, it is either a short
          connection loss or it is just your problem. _Do not post these
          questions here or anywhere!!!_
          
   * Advertisements for muds
          These belong in the newsgroup rec.games.mud.announce.
          
   In the event someone does post improperly to the newsgroup, readers
   should quietly inform the poster of the misstep via email. In the
   past, violations of the Charter or FAQ have erupted in
   counter-productive flame wars. By emailing the offender, you
   accomplish both the tasks of informing the person and of keeping the
   newsgroup free of pointless arguments.
   
     _________________________________________________________________
                                      
    I disagree with something in the FAQ. How do I get the FAQ changed?
    
   You should email the maintainer of the FAQ. Change requests fall into
   three different categories. I handle the requests differently based on
   the category into which a given request falls. The three categories
   are:
    1. Matters of fact
    2. Matters of opinion
    3. Matters of consensus
       
   The first kind of issue are matters of fact--i.e. the status of mud
   software, the email address of a mailing list, etc.--then I will
   simply add that to the FAQ. If you are not directly responsible for
   the issue in question, I might request an email from the person who
   is.
   
   Matters of opinion will likely not replace existing passages, but
   instead appear alongside them. For example, the FAQ might state that
   capturing player emails is a good idea. Someone who disagreed strongly
   and presented an argument could email that argument to me. Since this
   is a matter of opinion, the new opinion would be added as an opposing
   opinion. In other words, it would not replace the existing clause.
   
   Certain issues, such as the interpretation of the Charter, are neither
   matters of fact nor matters of opinion--they are matters of consensus.
   These are parts of the FAQ for which only one point of view can be
   right, yet a certain minority of people may nevertheless disagree
   with.
   
   The FAQ has been around for a long time and represents the consensus
   of the newsgroup. Consensus does sometimes change, and the FAQ needs
   to be able to adjust with changes in consensus. For matters of
   consensus, I will ask anyone making a request to provide evidence that
   the consensus of the group has changed. Because the FAQ is established
   as the consensus of the newsgroup, the burden of proof is entirely on
   the requester. The nature of that proof is naturally dependent on the
   issue at hand.
   
     _________________________________________________________________
                                      
    What is an LPMud?
    
   An LPMud is one of many classes of muds, or multi-user domains. A
   multi-user domain is defined solely with respect to its ability to
   allow multiple real individuals to come together in some sort of
   environment. Although the most common environment is a gaming
   environment, muds need not be games. In fact, among other uses of MUDs
   that I know of, there are virtual colleges, a mud where victims of
   abuse can come together in a productive environment, and muds designed
   to bring students with disabilities into social contact with one
   another and others. The single defining theme for mud is therefore
   being a virtual environment where multiple people come in contact.
   
   An LPMud specifically allows the users to manipulate the environment
   through a language called LPC. LPMuds are computer programs which
   listens to the internet for people attempting to connect, reads LPC
   files, and acts upon those LPC files according to the rules of the LPC
   language to create the virtual environment. Currently, I know of 6
   major LPMud servers:
   
   * CD
          
   * DGD
          
   * LPC4
          
   * LPMud
          
   * MudOS
          
   * Shattered World
          
   With most other mud games, users do not have access to create in the
   language used by the mud. LPC is used not only to give users such an
   ability, but it is also designed with both ease and power in mind.
     _________________________________________________________________
                                      
    Isn't Amylaar an LPMud?
    
   Amylaar is a person, not an LPMud. He is the primary author and torch
   bearer of the LPMud name. Given the generic sound of the term "LPMud"
   these days, people often refer to LPMud 3.2 as the Amylaar driver.
     _________________________________________________________________
                                      
    Which is the real LPMud?
    
   LPMud 3.2 is the official continuation of the original LPMud server,
   however, all servers listed above are equally real. All have two
   traits that make a mud an LPMud:
    1. The environment is created through files written in LPC.
    2. The environment can change as new files are added and old ones
       changes, even while the game is running.
       
     _________________________________________________________________
                                      
    How did LPMuds get started?
    
   I am not the greatest historian, and may be wrong on some important
   facts here, but this is the first shot at the FAQ, so here goes...
   Once upon a time, there was Lars Pensjö (the ö being an o with two
   dots over it... to an American, that is roughly pronounced "Penscha"),
   who wrote the original LPMud coming from an AberMUD background. If you
   play current LPMud's of the LPMud type, you won't really notice much
   of a difference from the original. From the coders' point of view
   however, LPC is nothing like it was with the original. For a long
   time, there was only LPMud run by Lars with patches by everyone under
   the sun. The original LPMud run by Lars was called Genesis. Its base
   town called Larstown was taken mostly from AberMUD.
   
   Eventually, others got tired of waiting to see their patches added to
   Lars' driver, and Lars was working on version 3.0 of his driver as he
   was gradually losing interest in the project altogether. Version 3.0
   turned out to be buggy as hell, and generally unworkable for a real
   LPMud. CD, LPC4, LPMud, and MudOS, all derive from this server as
   people saw good things in it and began creating working versions of
   LPMud 3.0 after their own concepts of mud server design.
   
   Unlike the others, DGD was created from scratch. It therefore is
   missing a lot of the baggage which has come down from the beginning of
   time in the other drivers. Shattered Worlds, on the otherhand, derives
   from LPMud 2.4.5.
     _________________________________________________________________
                                      
    What is the difference between LPMud and Dikus?
    
   This section is almost entirely quoted from a post by Tim Hollebeek:
   The main difference between Dikus and LPs is that a Diku server
   provides a game, while an LP server provides a language in which to
   write a game. This means that an LPMud server is more like your perl
   or python binaries than a Diku binary. An LPMud has an extra layer in
   which the game is written, called the mudlib or object library. The
   advantage Diku enjoys is that it can be more efficient since the game
   is more low-level. The other edge of this sword, however, is that it
   is very hard to make changes to a Diku and it requires a high level of
   technical knowledge.
   
   An LPMud, on the other hand, is extremely flexible and requires a
   minimal amount of technical knowledge in order to build the same
   things (or even more complex things) as exist on Dikus. As a
   consequence, LPmuds tend to be more widespread and reflect a greater
   diversity of imagination.
   
   The truth about LP's is that it is virtually impossible for a player
   to know they are on an LP; the driver is simply too far removed for it
   to make any difference to the player in terms of look and feel. Many
   LP's, however, do have a common look and feel because they share the
   same mudlibs.
   
     _________________________________________________________________
                                      
    What do the terms "alpha testing", "beta testing", and "fully open" mean?
    
   Generally, a mud goes through three basic stages. The first stage,
   "alpha testing", is a developmental mode in which players are rarely
   allowed access to the mud. Things are in such a disarray or in a
   flurry of changes that playing a consistent game is impossible. In the
   "beta testing" stage, a mud is generally opened to players solely for
   the sake of testing that the mud works. Without actual play testing,
   it is impossible to determine if a mud can handle being fully open.
   muds in either of the above stages generally will not compensate
   players for mishaps due to bugs in the game, and they will often even
   purge players from the mud. The purging is done either because old
   player objects are no longer compatible with new ones or because the
   mud needs to be re-balanced to fit new code.
   
   In the final stage, "fully open", a mud is just that, fully open. That
   means you can expect certain standards from the mud, including such
   things as not dying from bugs. Nothing is ever bug free, so generally
   fully open muds will compensate players for mishaps which occur
   because of a bug. On the flip side, these muds usually also smite
   players who gain from bugs in the system.

     _________________________________________________________________
                                      
    How do I play an LPMud?
    
   You must first find the internet address of the mud you wish to play.
   Once you find the address, most often people use the "telnet" program
   to connect to this address. The mud FAQ has an excellent section on
   MUD clients, which are alternatives to the plain vanilla "telnet"
   program. However, generally speaking, with "telnet", you can access
   the mud of your choice by issuing the command:

        telnet address port

   For example (% is considered your prompt):
        % telnet nightmare.imaginary.com 1701
        % telnet 129.10.114.86 5555

   And so on. Some telnet programs do not allow you to pass arguments at
   the command line. Instead, you get something like this:

        % telnet
        telnet> open
        (to) nightmare.imaginary.com 1701

   Once you succeed, you will get a welcoming screen which should say the
   name of the LPMud and ask you for a name. A common error people will
   make is leaving off the number at the end. If you do that, the telnet
   program assumes you mean to go to port 23, and it will give you a
   login prompt to the host machine.
   
   In addition, _some_ VMS telnet programs use the following syntax:
        telnet 198.174.169.120/port=1701

     _________________________________________________________________
                                      
    But I am using windows!
    
   The telnet program that comes with Windows95 and Windows NT is
   extremely anemic and not much good for anything. Other versions of
   Windows do not even come with a telnet program. To connect to a mud
   using the default Windows95/NT telnet, go to the 'Start' menu and
   click on the 'Run' menu item. In the text field, enter:

        telnet nightmare.imaginary.com 1701

   Of course, you should use the proper address for your mud as described
   in the telnet section. This will connect you to the mud, but it may be
   a bit confusing. The first thing you need to do is turn echo on so
   that you can see what you are typing. Go to the 'Terminal' menu and
   click 'Preferences'. Check the 'Local Echo' check box. You may also
   want to resize the window so there are no scroll bars.
   
   You will not be able to stand playing a mud this way for very long. It
   is highly recommended you download a Windows mud client ASAP before
   you go insane. In the least, you might want to grab a useable telnet
   program like EWAN or CRT.

    How do I get a list of LPMuds?
    
   I know of no place that lists ONLY LPMud's, however, there is Doran's
   Mudlist, which is produced semi-regularly and lists muds by type. You
   thus have all your LPMuds grouped together. You can find it posted to
   rec.games.mud.announce.
   
   MUDs connected to the Intermud generally have mudlists which they
   maintain dynamically based on which muds they are currently talking
   to:
   
   * http://ie.imaginary.com:7885/gateways/mudlist
          The Idea Exchange Dynamic Intermud Mudlist
          
   Keep in mind, however, these dynamic lists hold only LPMuds which
   support intermud communication. They are by no means full lists. You
   will also find that many muds on this list are in some sort of
   developmental stage.

    Are all LPMuds in English?
    
   No. To provide a list of such muds is beyond the scope of this FAQ.
   Check the mudlists for a full and current listing. However, I would
   like to know about other languages which might be supported in the
   LPMud world, so please mail me if you have a mud in a language in
   other than English, German, or Swedish. Known languages:
   
   * Chinese
          
   * Dutch
          
   * English
          
   * German
          
   * Hungarian
          
   * Polish

    Ok, the mud is asking me for a name, what do I do?
    
   Make up a name. Avoid using your real name or common names, real and
   mythical. You want not only to give character to your persona, but you
   also do not want everyone saying "Hey! Aren't you Bob from
   JustAnotherMUD"? I chose the name Descartes, because I was a
   philosophy major in college. In general, it is safe to assume any name
   consisting only of more than two characters and less than ten (a to z)
   is acceptable on any mud. Some muds allow really long names with
   spaces, apostrophes, hyphens, and other marks. Others are in between
   the extremes. Try the name you want. If the mud will not allow it, it
   will tell you, and it should tell you why.
   
   After making up a name, one of two things will happen. Either you will
   be prompted for a password, meaning you have picked a name someone
   else is using, or it will ask you to create a password, meaning you
   are a new character. If the first thing happens, just try again with
   another name. If the second happens, you are in good shape.
   
   To create passwords, make up one different than the one you use to
   access computers. Although muds encrypt passwords for storage, nothing
   prevents an unscrupulous mud admin from intercepting that password and
   using it for unethical purposes. It is also recommended that you use a
   password with numbers and mixed upper and lower case letters in it.

    They told me I had to register!
    
   Some muds require all their players to register before being allowed
   to play. Also, it may be the case that someone from the same place as
   you has been causing trouble, so the admins of the mud in question
   have decided to require only people from that site to register. If
   this is the case with the mud you wish to play, simply follow the
   instructions they give. In most cases they will give you an email
   address where you should send your registration.
   
     _________________________________________________________________
                                      
    Name and password set, what next?
    
   This is where you get to see why there is so little in common among
   LPMuds from the player's point of view. Some LPMud's will ask you a
   series of questions about who you are and what sort of character you
   would like. Others ask nothing more. Among the questions you might be
   asked are: what is your email address? what is your real name? what
   gender would you like to play? what race would you like to be? what
   class would you like to be? etc.
     _________________________________________________________________
                                      
    I don't want anyone knowing my email address!
    
   MUD Administrators have a legitimate need to know your email address.
   No one else does. If a mud requires you to give your email address it
   should either offer you the option of keeping it private, or it should
   automatically keep the email private. If they do not keep your email
   private and you desire privacy, do not play the mud. Do not complain,
   however, that they ask for it.
   
   _Note:_
   There seems to be some difference of opinion on this one, so I decided
   to quote one of the comments:
   
     "Well, I have to disagree with this section: E-mail addresses are
     very difficult to verify in bulk, and really not worth the trouble
     unless you perform site registration. I believe the only people you
     have a legitimate need for an email address from is your wizards.
     Other than that, knowing the ip they log in from should be more
     than sufficient." -Rust (John Viega)
     
     _________________________________________________________________
                                      
    Is it asking me for _my_ gender?
    
   No. The game wants to know what gender you would like your _character_
   to be. This means you can play a character of the opposite gender,
   your own gender, or one of the alternate gender types which might be
   offered. The other side of the coin to this, however, is that you
   should _never_ count on other people in real life being the gender of
   the character they play.
     _________________________________________________________________
                                      
    What does it mean by race?
    
   Many LPMuds have a feature called character races. The term "race" in
   these instances is not the same as the term used in modern society. In
   fact, the LPMud term race would more correctly be referred to as
   species. In fantasy type LPMuds, you will often see a selection of
   "races" like human, orc, artrell, gnome, etc. When you are asked to
   choose a race, a list of possible races should be provided for you.
     _________________________________________________________________
                                      
    What is a class? What is a guild?
    
   In general, a class is a grouping of players with common abilities. A
   guild as well can be said to have the same definition. Many muds, if
   they use either of these concepts at all, add some very individual
   nuances. To muds which do not have classes or guilds, the concepts are
   naturally irrelevant. Those which have one or the other are often
   using the terms in an interchangeable fashion. Finally, those muds
   which have both often define class in a more generic manner than
   guild. For example, on Nightmare, a class is like a profession and the
   guild like a particular job. You might have people in the fighter
   class who are in the templars guild, and others who are in the rangers
   guild. In short, the guild is a way of specializing your class
   abilities.
   
   Other muds allow "multi-classing", which may mean joining multiple
   guilds, classes, or both. It is always best to check out the "help
   guild" and "help class" command on any given mud to see how it defines
   these terms.
     _________________________________________________________________
                                      
    I am in the mud, what do I do?
    
   There is no one answer to this question, as the answer will vary from
   MUD to mud. No matter what, however, you should see if the mud has a
   "faq" command to get a listing of that mud's frequently asked
   questions. In addition, you should learn how to use the "help" command
   as well as find out about the rules governing that mud.
     _________________________________________________________________
                                      
    What are some common commands?
    
   The following commands exist on virtually all LPMuds. () around part
   of a command indicate that that part is optional. [] indicates that
   the text should not be taken literally. These commands naturally are
   not likely to be found on non-English muds.
   
   * help ([topic])
          Gives you help. If you specify a topic, you get help on that
          topic. If you just type help, you will either get help on where
          to find other help, or you will be put into a help menu.
          
   * tell [player] [message]
          Sends the string [message] to the player whose name is [player]
          anywhere on the mud. Some LPMuds do not allow players to tell
          to one another as it is viewed unrealistic.
          
   * say [message]
          Sends [message] to everyone who is in the same mud room as you.
          This command is almost always aliased to "'", such that "'hi!"
          is the same thing as typing "say hi!".
          
   * who
          Gives you a list of everyone connected to that mud.
          
   * look
          Gives you a description of the mud room in which you are in.
          
   * look at [object]
          Gives you a description of the object in question.
          
     _________________________________________________________________
                                      
    What is an alias?
    
   As with UNIX, most LPMuds provide some sort of method for creating
   "aliases". An alias is simply a way in which you can have a easy to
   type command represent another command. For example, you will often
   want to type the phrase "get all from corpse" on any LPMud. It is much
   easier to make an alias so that whenever you type "gac", the LPMud
   interprets that as "get all from corpse".
   
   In order to create aliases, you need to know how your particular mud
   handles aliasing. Older muds use a device called a quicktyper. Newer
   MUDs have alias commands built in. Try issuing "help alias" and "help
   quicktyper" commands in order to find out how aliases are handled on
   your mud. If your mud uses quicktypers, you will have to go find the
   quicktyper object before you can create aliases. Ask any other player
   on such a mud where there quicktyper can be found.
     _________________________________________________________________
                                      
    Why is the mud admin ignoring me?
    
   Admins in particular are prone to a mud disease called "idling". This
   means that the lights are on, but nobody is home. An idle person is
   simply someone logged in to the game, but who is perhaps not actually
   at their computer terminal. That person is thus not really ignoring
   your question, since the person is never actually seeing it.
   
   If the admin is not idling, chances are that person is being
   overwhelmed with questions or is actually coding online. Many LPMuds
   will tell you that the person to whom you are talking is "idle" or
   "editing". If you get that response to a tell, do not expect an answer
   back right away. In addition, if it says the admin is editing (or
   anyone else for that matter), then it is generally considered rude to
   continue telling to that person as it makes it difficult for the
   person to edit.
   
   Many people these days have the ability to be on several muds at the
   same time. It is therefore entirely possible that the person to whom
   you are trying to talk is in fact looking at another window. To get
   that person's attention, it may be ok to "beep" them (by sending a
   control-G in a say or tell). Some people do not like others to do this
   to them, however, so be careful about doing it too much.
     _________________________________________________________________
                                      
    The admins are being unfair, don't I have rights?
    
   The short answer is yes, you have the right not to play the game. The
   long answer is much more complex. First off, any reasonable set of
   admins who wish to create a game which people will enjoy will
   enumerate the sorts of behaviour you can expect from them. In other
   words, admins on fun muds will state the rules of the game ahead of
   time and will not deviate from those rules. That way you know what to
   expect. In addition, if you do not like the rules, you don't get
   involved with playing the game.
   
   What prevents an admin from breaking their own rules? Absolutely
   nothing. In one sense, a mud is like someone else's swimming pool. You
   have absolutely no right to swim there, and they have the right to
   throw you out just because you talk funny or say things they don't
   like. Fortunately, there are plenty of muds out there with civil
   administrations to make this nothing more than a passing nuisance.
   
   A common misconception is that mud admins administrate muds for power,
   and that arbitrary behaviour is a way of exercising that power. Though
   there may be a few misguided individuals out there who do in fact
   administrate muds for the sake of power, the fact is that no mud
   administrator has any power over you. Remember, the worst thing any
   admin can do to you is make you go play somewhere else.
   
   A final thing to remember is that muds evolve and rules evolve with
   the mud. Just because rules change does not mean the admins are being
   arbitrary. Arbitrariness is reflected in sometimes applying rules and
   sometimes ignoring them, not in creating new rules to fit unforseen
   situations.
   
     _________________________________________________________________
                                      
    What about freedom of speech?
    
   No, not even freedom of speech. Again, reasonable admins will clarify
   in publically available rules what sort of speech (hate speech,
   offensive language, or whatever) is not acceptable on that mud. You
   may or may not agree with those rules or the political beliefs those
   rules represent, but at least you do know where you stand on the mud.
   It is thus up to you to decide if you can play under those rules or
   not. In the event you encounter an unreasonable mud, there is nothing
   much you can do but decide to leave. If it is a commercial mud,
   however, deciding to leave can be some sort of leverage.
   
   A common source of friction between players and admins is where
   players decide to criticize admins. Most often, the players are not
   really trying to criticize the admins so much as inspire positive
   changes to make a game they love even better. In those cases, it is
   always good to remember that the admin is a real human who is closely
   involved with what the mud is. If you keep that in mind, you can often
   help bring positive changes to the mud you play without
   unintentionally striking a hidden chord in a sensitive admin.
   
     _________________________________________________________________
                                      
    What else is there?
    
   Explore the mud! Most gaming muds have places called "newbie" areas
   which are simplistic places for people new to the game to go and get
   the hang of things. When you first log in to a new mud, you should ask
   the others where the newbie area is. Also, read the login screen and
   news which scrolls across your screen at login time, as they contain
   important information about characteristics unique to the mud you are
   playing.
   
   Ask people questions. Just make sure you have read the help files
   first, or you will be sure to annoy someone. In addition, try not to
   choose a single person for your queries. Constantly being asked
   questions by the same person can often annoy people as easily as
   stupid questions.

    What is coding?
    
   Coding is writing files for the computer to read. In the case of
   LPMuds, this means writing files in a computer language called LPC.
   The LPMud server reads these files and interprets what those files are
   telling the computer to do when certain player actions occur. Often
   that means things like displaying a description of a room when you
   enter it and so on. The LPC files which make up the backbone of any
   mud are called the mudlib. Coders use the mudlib code in such a way as
   not to have to rewrite many of the most common instructions over and
   over again. With most good mudlibs, therefore, there is more creation
   involved than coding.
     _________________________________________________________________
                                      
    What is LPC?
    
   LPC is an object building language created by the author of the
   original LPMud server, standing for Lars Pensjö C. Structurally, it is
   much like the more popular programming language C. Designed with LPMud
   object building specifically in mind, it puts the power of game
   building in the hand of the general user.
     _________________________________________________________________
                                      
    How do I get to code on an LPMud?
    
   Policies vary from mud to mud. Some muds require you to make a certain
   player level before being allowed to code. Others require you to pass
   a test or fillout an application. Still others just let anyone come on
   and code. If you really want to get in on things, the best thing to do
   is either to talk to the admins of the mud you are playing, or go to
   The Idea Exchange (ie.imaginary.com 7890) The Idea Exchange has a
   newsgroup for coders looking to code and another for muds looking for
   coders. Keep in mind that many muds which are open to players already
   have more coders than they need.
     _________________________________________________________________
                                      
    How do I learn to code?
    
   There are two parts to learning how to code on your mud:
    1. Learning LPC
    2. Learning your mud's object library (mudlib)
       
   Each mud should have detailed documentation on part 2. Two LPC
   textbooks, a beginner and an intermediate, exist to take care of part
   1. You can get the textbooks via ftp at
   ftp://ftp.imaginary.com/pub/LPC/. Documentation, however, will not
   really do anything without looking at examples, practicing, and
   talking to more experienced coders. Examples should be everywhere on
   your mud (though they are not necessarily good examples). Practicing
   is simply just copying code you do not understand, making small
   changes to it to see what they do, and learning from what happens. To
   learn more about how to code from others, talk to more experienced
   coders on your own mud or visit The Idea Exchange which is designed to
   help people learn LPC.
     _________________________________________________________________
                                      
    What is The Idea Exchange?
    
   The Idea Exchange is centered around the advancement of LPMud
   technology and the promotion of its use. On The Idea Exchange you will
   find many of the people responsible for the software commonly used to
   build LPMud environments, including the authors of drivers and
   mudlibs. It is an excellent place for learning about LPC and
   discussing new ideas.

    How do I code a monster/room/weapon/armour...?
    
   Read your mud's documentation, as this varies greatly from mud to mud.
   
     "Also, questions like that are almost impossible to answer in any
     other way than showing an example. Thus, a much better question is:
     'Where can I find an example of how to create a XXX?' or 'I don't
     quite understand this part of the example on how to...'" -Drevreck
     (Lars Syrstad)
     
     _________________________________________________________________
                                      
    But you said all LPMuds use LPC!
    
   Yes, they do. However, they do not all use the same mudlib. The mudlib
   is the basic LPC files you make use of then you write your LPC files.
   The LPMud server in turn interprets your files and stores them in
   memory. Two muds using different mudlibs therefore can be wildly
   different from one another. And since the mudlibs are so different,
   the files you will write will be equally different.
   
   An analogy might be that of a human dialect. Quebecois French and
   Continental French often use different words and such in order to
   express ideas. In spite of this, the language structure is the same.
   So, both are still French even though you sometimes need to say
   different things in order to mean the same thing.
   
   In writing an object in LPC, you are almost always using the mudlib's
   LPC files rather than totally writing files from scratch. You do this
   through something called inheritances. Inherited code which exists on
   one mud may not exist on your mud, or may exist differently. Therefore
   when you try to use that code, it will not work as you expect even
   though both are in LPC.
     _________________________________________________________________
                                      
    My code is not working! How do I fix it?
    
   First, determine if the problem is with...
     * the object failing to load
     * the code causing an error when it runs
     * no errors, it is just the expected things do not happen
       
   Now that you know what "type" of error you have, you need to isolate
   it. Isolating it depends on the type of bug...
   
   _the object fails to load_
          You have the bug isolated for you you in your error file. The
          location of the error log depends on the file name of the
          object with the error. It also depends on the way your mudlib
          logs such errors. Nightmare, for example, logs compile errors
          to /log/errors/std for obejcts in /std, etc, and
          /log/errors/descartes for objects from /realms/descartes. TMI-2
          would log my errors to /u/d/descartes/log and mudlib errors to
          /log/* with sensitive logging going to /log/adm/*. _know_ with
          MudOSthe driver does isolate the error for you to a useful
          degree of certainty. More on this later.
          For LPMud 3.2.1, you can use the: #pragma verbose_errors
          preprocessor directive to make compile time errors include a
          bit of context in error messages. Some mudlibs turn this
          #pragma on by default.
          
   _an error occurs during execution_
          These are logged in the mud's runtime error logged, and they
          ALWAYS reflect the exact line where something happened. On
          MudOS muds before 0.9.20, the system runtime log was
          /log/debug.log. The mudlib in later versions has the option of
          naming it whatever.
          
     "Brought over from LPMud 3.[01].x , LPMud 3.2 uses
     /`hostname`/debug.log. LPMud 3.2.1 allows you to pass the option
     --debug_file to change this default. If there is a triple fault
     (i.e. an error while the master was processing an error in error
     processing), and you compiled the driver with the TRACE_CODE
     option, there will also be a trace of the last instructions
     executed. Moreover, if the driver is not out of memory, and there
     is no triple fault, the apply runtime_error() is called in the
     master, with the error message, file name, object name and line
     number as arguments." -Amylaar
     
          Note that for drivers which can compile LPC code to C and then
          link it into the driver, no line number information will exist
          to help you in debugging. You should therefore debug your LPC
          code thoroughly before compiling it to C.
          
   _no errors, you just do not get expected results_
          These are the hardest to debug. You need to go through the code
          and test
          
         1. Which code is being executed
         2. The values of the variables in the executed code
            
          How do you do this? Take the following code with a priveledges
          bug...
          

/* from /cmds/adm/_rid.c */

int cmd_rid(string str) {
    if(!archp(previous_object())) return 0;
    if(!str || !user_exists(str = lower_case(str))) return 0;
    if(!((int)USERS_D->rid_user(str))) return 0;
    message("system", "You rid "+capitalize(str)+".", previous_object());
    return 1;
}

/* EOF */

/* /secure/daemon/users.c */

int rid_user(string str) {
    return rm(DIR_USERS+"/"+str[0..0]+"/"+str+SAVE_EXTENSION);
}

/* OTHER CODE DELETED FOR BREVITY */

   This is not real code (as a lot more should exist in such an
          operation). However it does serve the point. This code will
          load fine and execute without error. However, it will not
          delete the save file of any user. If anyone executes it, the
          following will happen:
          

> rid weenieplayer
What?
>

   So what do you know? You know you typed "rid weenieplayer", and you
          know you got 0 returned. One of the following things happened:
          
         1. The "rid" command never got executed
         2. The archp() returned false for the person executing the
            command
         3. For some reason, str was equal to 0
         4. rid_user() in users.c returned 0 to the command
            
          How do you know if 1 is the problem? put the line... write("rid
          command executed") as the first line of the cmd_rid() function
          in the rid command. If the rid command is executed, you will
          see that it is executed before you see "What?". If it is not,
          you will just see "What?". If you do not see that line in
          write(), then you know your bug is with you whatever calls the
          "rid" command. If you do, then you know you must proceed
          further.
          
   Do the same after each line which returns 0. Make sure each write()
   string is unique so you know *which* line is being written out. This
   will tell you exactly *which* line is returning 0 in the rid command.
   
   In this case, it is #4 which is the problem. The users daemon is
   returning 0 for for rid_user(). This means that rm() is definitely
   returning 0. rm() only returns 0 when an rm fails. rm() only fails
   when an object does not have proper access. Therefore, in this case,
   you need to fix the bug in your security.
   
   If for some reason you cannot go editing the files in question (i.e.
   they are in the base lib files to which you have no access, changing
   them would be even more troublesome, etc), you should consider the
   efuns trace() and traceprefix().
   
   Do you need to go through all of these tedious steps? No, you can
   generally make good guesses as to where to look the more familiar you
   become with the code. For example, in this case you pretty much could
   have elimited step 1 if that command is an old command which used to
   work. After all, it is highly unlikely that the mud would suddenly
   stop executing that one command!
   
   Furthermore, if you had just made a change to the security system, you
   would immediately suspect that rm() failed and thus would have checked
   that first.
   
   This is why presenting me with your entier rid command would have been
   useless to me. I would have looked at it and said it *looks* ok. But I
   have no idea what changes you have recently made to your mud, nor do I
   know from looking at the code which of those lines is returning 0. I
   can only basically tell you that one of those lines is failing.
   
   However, if you were to tell me that for some reason your user object
   was returning 0 in trying to rm() the user file during the rid
   command, I could tell you details about the relevant parts of the
   Nightmare LPC Library security to this daemon. And then you could use
   that information to debug further and ultimately fix the bug.

    What is an efun? an lfun? a kfun? an sefun?...
    
   For any function in LPC, there are three distinct parts...
    1. the prototype
    2. the call
    3. the definition
       
   Whate differentiates all of these different types of functions is
   _where_ they are defined. The definition of the function is the part
   which says what it does.
   
   afun (auto function, DGD only)
          the function is defined in the auto object and behaves like and
          efun from other drivers. This function is really very special
          type of lfun.
          
   apply
          a function defined in the mudlib designed to be called only by
          the driver. All applies are also lfuns. Most of the functions
          in the DGD's driver object and other's master object are
          applies. In addition, the functions create(), init(), and
          reset() are also applies for LPMud 3.2 (not 3.2.1), MudOS, and
          CD.
          
   efun (external function)
          this type of function is defined external with respect to the
          mudlib. In other words, in the driver. Since it is defined
          inside the driver, it is faster, but the mudlib is left with
          little control over what it does.
          
   kfun (kernel function, DGD only)
          This type of function is much like an efun in that it is
          defined external to the mudlib in the driver kernel. There are
          some ways beyond the scope of this FAQ in which kfuns differ
          from efuns, ways which have little bearing to daily coding.
          
   lfun (local function)
          Any function defined inside an object in the mudlib. The
          functions you write (like create() or reset()) are lfuns.
          
   sefun (simulated external function)
          lfuns defined in an object known as the simul efun object. Any
          object in the mudlib is allowed to use these functions as if
          they were efuns (treat them like local calls).
          
   You might also want to keep in mind the difference between a local
   call and a call_other. A local call is a call to a function defined in
   your object or to one of the objects it inherits. A call other is a
   call to a function defined in another object. Efuns and simul efuns,
   though not defined in your object, act like local calls. Afuns and
   kfuns are in fact local calls, since all objects inherit the auto
   object to which they are local.

    Can I take my area from LPMud X to LPMud Y?
    
   Can you? If they use the same mudlib, yes. May you? Often muds have
   restrictions against importing code in order to keep the mud unique.
   Talk to the administration of both muds for local details.
     _________________________________________________________________
                                      
    Can I code offline?
    
   There are many different methods of coding offline, and which one is
   available to you depends on your mud. The methods are:
    1. ange-ftp
    2. your favourite editor + ftp
    3. cut-and-paste
       
   Editing offline allows you a faster response time, the ability to
   multitask, and the ability not to be bothered by incoming tells
   screwing up your edit window. It also allows you to make use of
   editing environments which may be much more robust than standard mud
   ed.
   
   ange-ftp is an emacs mode which allows you to edit files in emacs and
   have them automatically ftp'ed to your mud and back. ange-ftp
   requires:
     * emacs with ange-ftp mode
     * an FTP server which gives access to host mud files
       
   Using a local editor and ftp allows you free choice of which editors
   you use, but you have to manually transfer each file. If going from a
   DOS environment, you also need to watch for carriage-return/line-feed
   translation. FTP requires:
     * An FTP server which gives you access to your mud files
       
   Cut and paste requires no file transfer and allows you to use any
   editor which has immediate access to your mud files. For example, you
   can edit on your home computer using Notepad, then cut that from
   Notepad and paste to your mud window which is likely in ed. Cut and
   paste requires:
     * The ability to cut and paste from editor to mud window.

    How do I put my code into the game?
    
   A file is considered "in the game" if another file already visible to
   players references it. So, to put your stuff in the game, you need to
   change code already in the game to reference your code. This action
   normally requires the action of mud administrator. Most muds have some
   sort of quality control policies which state rules for having your
   code reviewed.

     _________________________________________________________________
                                      
    How do I find a site?
    
   The most common method is to talk to the administrator of the machine
   from which you access muds and the rest of the Internet. If the
   resources are available, they will often allow you to run your mud
   server unless something political like a no-games policy is preventing
   it. If you are not running a mud as a game, however, this is not
   relevant.
   
   Never run a mud without talking to your system administrator. LPMuds
   take up a lot of system resources, and many places simply cannot spare
   those resources on a single project, especially if the project is
   non-essential to the functioning of the entity running the machine.
   Not only is it just plain wrong to run a mud without permission, it
   also predisposes sysadmins to saying no to people who ask them when
   the resources are free.
   
   If you cannot run it on your local machine, post a note to the
   ie.sites.wanted newsgroup on The Idea Exchange. Do not post to USENET
   newsgroups unless you have a working mud. It does not need to be
   complete, but posting notes saying "I have a cool idea, will someone
   give me a site" is inappropriate, unless that idea is completely
   fleshed out with some sweat in the form of work on paper and such.
   
   Another avenue of finding a site is talking to local internet access
   providers. Often, they have extra small machines on which a mud could
   be run (sometimes for a fee). The most expensive route is to buy your
   own machine and your own Internet hookup.
     _________________________________________________________________
                                      
    Can I charge players to play my mud?
    
   If you write the server from scratch AND you wrote your mudlib from
   scratch and you have agreements with the coders who wrote areas on
   your mud, the answer, of course, is yes. The above will take roughly
   3-5 years of full-time work to accomplish as well.
   
   If you do not wish to go through all of that time to write your own
   server and object library, then you may only user DGD. Of course, you
   will have to get express permission from Dworkin. The only object
   library you may use for such purposes is LPMoo.
     _________________________________________________________________
                                      
    Why can't I use any of the other servers or mudlibs?
    
   They all come with some variation of the same copyright. Since all
   drivers except DGD were derived from LPMud 3.0, they all require a
   copyright at least as strict as that one, which basically states that
   you can use the server as you like, so long as you do not make a
   profit off of its use. Most current servers have much more strict and
   explicitly copyrights. On top of that, many of the mudlibs which exist
   also have similar copyrights. To require money of your players is
   therefore a violation of international copyright laws. DGD requires
   licensing through a third party company.
   
     _________________________________________________________________
                                      
    Our system needs upgrading, can't I get donations?
    
   Yes, you can request that your players donate money as long as the end
   of that money is to run the mud and donations are not a prerequisite
   for play on the mud. In other words, they must be donations, not fees.
   
   _Note:_
   I am not a lawyer, nor am I the author of all the mud code out
   there... Therefore, keep in mind that what I am saying about
   copyrights is my interpretation and not binding upon ANY of the server
   or mudlib authors out there. For reference to what is binding with
   respect to my code, see the copyright notice which accompanies it.
     _________________________________________________________________
                                      
    I have a site, now how do I choose a server/library?
    
   Some people have a favourite mudlib, and therefore go at building
   their own mud from the angle of using that mudlib. Others have a
   favourite server and start from that angle. Others simply want to
   start a mud fast, while others want to really tinker with it and make
   it their own. The following is a rough guide to what is out there:
   
   _Note:_
   Also, I only publish software which the authors have somehow made
   known to me to be available, or in fact are widely known to be
   available. I will not publish information about software which I have
   no such verification, since being on a public ftp site is not the same
   as being publically available.
   
                                  Servers
                                      
   CD
          Generally considered a slow driver, however it is designed to
          work very closely with the CD-lib. Therefore tests showing the
          CD driver to be slower are not necessrily fair as sole factors
          since they are mudlib-independent tests. The CD-lib is
          considered a well designed lib which is often a factor which
          leads people to choose this server. To see a CD server mud,
          visit Genesis.
          
   DGD
          DGD is built on the belief that small is good. This is absent
          of much of the extra baggage which exists in all other drivers
          since it was created from scratch. There currently exist only a
          few, small native mudlibs for DGD, one of which is a MOO
          simulation. DGD's documentation is sparse. It includes dynamic
          object version updating amd supports compile time LPC->C
          compiling, meaning that when you compile the driver you can
          have some of your LPC files converted to C and compiled with
          the driver. In addition, unlike other LPMud servers, it is
          disk-based, meaning you can run a huge mud on virtually no RAM.
          You therefore never need to reboot or save objects. Dark has
          written a TCP/IP socket support for DGD which can be gotten
          separately from the driver. Erwin Harte is managing a network
          package for the driver.
          
   LPC4
          Maintained by Profezzorn, it supports a scripting feature that
          allows you to execute LPC files as atomic programs without
          running the mud in the traditional sense. In addition it
          features lambda closure types which are actually understandable
          to most people. It is designed for speed through the philosophy
          of creating large numbers of efuns to perform CPU intensive
          work. I know of no muds using this driver in practice. LPC4
          also has socket efuns with TCP support.
          
   LPMud
          Once the fastest of all the drivers, it has lost this crown to
          MudOS. Nevertheless, it is an extremely fast driver which
          supports the old LPMud 2.4.5 Mudlib. It also supports closures,
          though its closure syntax is beyond general ease of
          comprehension. There is only one mudlib in wide release which
          is native to this server.
          
   MudOS
          The fastest and most feature-filled of the LPMud drivers, this
          one comes with TCP support for mudlib objects allowing you
          things like WWW, finger, SMTP, USENET, and other such access to
          Internet resources from inside the mud. It also comes with a
          choice of well-developed mudlibs native to the server. MudOS
          allows you to choose between UID support and no-UID support,
          which makes it easy to hack a LPMud 2.4.5 mud to work with
          MudOS if that is your cup of tea. MudOS supports a new function
          pointer syntax which is as functional as LPMud's closures
          without LPMud's obscure closure syntax.
          
   Shattered World
          Developed by one of the original LPMuds. I believe this driver
          originated from one of the first LPMud releases and has been
          heavily customized in such a way as not to be recognizable as
          such.
          
                              Object Libraries
                                      
   CD-lib
          I am told this is a very well-designed mudlib. Some features of
          it are an enhanced sense of reality through player recognition
          (you must make the acquaintance of players before knowing who
          they are) and UDP intermud communications.
          Runs under: CD (native)
          
   Dead Souls
          A public domain version of the former Nightmare mudlib. It
          contains a complete mudlib from which to build a world, but is
          very difficult to set up.
          Runs under: MudOS v21b25 (native)
          
   DGD Kernel Library
          A minimal development library that can be used as a basis for
          both continuous and non-continuous systems. It comes included
          with the DGD 1.1 release. Runs under: DGD 1.1 (native)
          
   Discworld
          Advanced command parsing system and user interface, as well as
          many concepts you will not see in other mudlibs for any server.
          Too many frogs and wombles.
          Runs under: MudOS 0.9.20 (native)
          
   Final Realms
          A modernized version of the Discworld mudlib.
          Runs under: MudOS
          
   Foundation IIr1.1
          A basic mudlib with nothing extra for people who want a solid
          design base from which to design a unique mudlib. No combat or
          anything else fancy is included. Nothing about it is
          pre-disposed towards fantasy or even game playing for that
          matter. On the positive side, there is nothing to deconstruct
          in order to build your own mudlib and there is more of a solid
          base to work from than something like Lil. The downside is that
          you will have to put in a lot of work to make a playable game
          from this.
          Runs under: MudOS v21.7b23 (native)
          
   Heaven 7
          A mudlib that essentially extends LPMud 2.4.5 with all the
          player features you always wanted such as classes, skills, and
          unlimited levels. It is well-suited to LPMud 3.2, but poorly
          suited to the other drivers under which it runs.
          Runs under: LPMud 3.2 (native)
          
   Lil
          A small, essentials only mudlib. Designed basically to give you
          examples of files as they must minimally be for the MudOS
          driver to run. Only useful if you plan really to write
          something totally from scratch.
          Runs under: MudOS (native)
          
   LIMA 1.0a5
          This is a brand new library, featuring the new MudOS natural
          language parsing package and a UNIX-like wizard shell with
          output redirection and command piping. In addition, it is a
          very modular, object-oriented mudlib with stack-based security.
          
          Runs under: MudOS v22.1b4 (native)
          
   LPMoo
          A MOO simulation using LPC. This library allows you to work and
          play exactly as if you were using MOO instead of LPC.
          Runs under: DGD (native)
          
   LPMud 2.4.5
          The most well-known mudlib in existence. It is rather simple,
          not the best design, but if you know it, it is useful. Also,
          the widest range of drivers support it. Good for putting up and
          running a mud quickly. It is very ancient and inferior in
          design, flexibility, and functionality to modern mudlibs.
          Runs under: DGD (non-native), LPMud 3.2 (non-native), LPC4
          (non-native)
          
   Melville
          Extremely minimalist mudlib for DGD. Documentation is sparse
          and it has few features. According to Dworkin, "Unfortunately
          it was never finished and today it is rather out of date. It
          does not work with recent versions of DGD."
          Runs under: DGD (native)
          
   Shattered World
          Mudlib to go with the Shattered World driver. It supposedly has
          a system for doing detailed economic and predictive analysis
          and is a distant descendant of the LPMud 2.4.5 mudlib. Other
          than that, I know absolutely nothing about it.
          Runs under: Shattered World (native)
          
   TMI-2 1.4
          Generic, designed for those who want to tinker around with
          their mudlib rather than get a mud up in no-time flat. Designed
          to be easily modified and comes with a full-range of intermud
          support as well WWW support. Features include the ability to
          take over monster bodies. Downside is its poor design and
          performance.
          Runs under: MudOS v21 (native)
          
   TubMUD
          Very intricate, and, according to Rust, "it is beautiful if you
          can figure it out." Intended more for Tub wizards to run at
          home than for wide-release.
          Runs under: LPMud 3.2 (native)
          
   If I have missed a lib, or stated something incorrect about your
   server or mudlib, or simply ommitted something, don't go flaming me.
   Email me the correct information so I can include it in the FAQ. I did
   my best to be fair in this, but in simply undertaking this task I have
   opened myself up to flames from anyone who I might have gotten wrong
   or simply does not like what I said. So please be gentle, and
   understand I mean no malice or ill-will anywhere in there!

    What about _Nightmare_?
    
   _Nightmare_ was removed from distribution by its author. No new muds
   may be built using this software. The Dead Souls mudlib, however, is a
   public domain version of the last available release of the Nightmare
   mudlib in a less user-friendly format.

    What copyright issues are involved with using someone else's code?
    
   Some of the software listed above was written by a single person.
   Other works are collaborative efforts. Of all of these, I know of only
   Dead Souls as being in the public domain. In other words, the authors
   have retained the copyrights on their code or assigned them to a
   larger group, yet thay have decided to allow others to use their code
   for free.
   
   Because these works are protected by copyright just like any other
   software you use, you may only use the software as long as you are not
   in violation of its licensing restrictions. The most common licensing
   restriction is to prevent commercial use without paying the developers
   a licensing fee. You need to read the licensing agreement of the
   software package you chose to determine if you can live with whatever
   restrictions it imposes.
   
     _________________________________________________________________
                                      
    But I have changed their code!/I don't see any copyright!
    
   There are two points to be made to anyone making these statements. The
   first is moral, the second legal.
   
   First of all, you used the original author's software. You did not
   have to use it, and they did not have to let you use it. Playing legal
   games based on legal technicalities (real or imagined) is slimey and
   unethical. The author of any code you use deserves your respect for
   their wishes regarding that code.
   
   Of course, there are people out there who cannot be bothered with
   issues of ethics. The question in their minds is, "Can I get away with
   it?" The answer is that you don't have a legal leg to stand on. Let's
   deal with the last question first. Any work--software, poetry, books,
   plays, films, etc.--is copyrighted from the moment it is created. No
   action is required by the author of the work in order for it to be
   protected. Certain actions (or lack of action) can weaken the
   protection an author has, but only two things can end that protection
   altogether:
     * The author assigns, in writing, ownership of the work to another
       person or entity.
     * The author places the work, in writing, into the public domain.
       
   Note that in either case, the author has to take a very specific
   action and has to do it in a very formal legal sense in order to end
   copyright protection for themselves. _Copyright laws do not require
   the author to register the work with any organization or government
   agency_.
   
   While you may think the fact that you live in a different country from
   the original author is protection enough for you, guess again.
   Copyright laws in most countries, while not identical, derive from a
   treaty signed by most countries. The net effect of this treaty is that
   copyright laws are very similar from one country to the next.
   
   As I stated earlier, there are things an author can do to weaken or
   strengthen their case in the event of a copyright violation. The
   degrees of strength of protection exist because there is a mild
   defense against copyright violation: ignorance. If a person can prove
   that they had no way of knowing a work was copyrighted (they believed
   it to be in the public domain because they believed either the author
   had placed it there or because the work was so old that copyright
   protection had lapsed). In this case, a person is limited in the
   damages they can suffer. The simplest action an author can take to
   protect against ignorance is placing a © along with their name and the
   date of the work's creation in a prominent location within the work.
   If it says it is copyrighted on its cover with a date within the last
   75 years, a defendent cannot possibly claim to believe the work was in
   the public domain.
   
   Of course, the other approach is to claim that the original author is
   not in fact the original author. This is where registering a work
   comes into play. By registering a work with an appropriate entity
   (like the Library of Congress in the United States), an author can
   prove that a given work is associated with them at a given time. If
   someone else wants to claim authorship of that work, they will have to
   prove the existence of the work in question prior to the date it was
   registered. There are even simpler ways of proving a work's
   authorship, such as mailing yourself a copy of your work without
   opening the envelope. Note, however, that such tricks are less
   authoratative than registering with an appropriate entity.
   
   So you are convinced you cannot claim the work is not copyrighted.
   What about works that have been changed? You are still out of luck. A
   work based on another work is considered a derivative work and thus
   subject to two copyrights: the author of the original work and the
   author of the modified portions of the new work.
   
   With respect to a derivative work, the first question is: do you even
   have the right to create a derivative work? Since the original author
   has a copyright on the original work, that person gets to specify the
   conditions under which you may use the original work. It is therefore
   possible that you are not even allowed to change any of the original.
   I do not know of any LP-related open distributions that prevent
   derivative works. Some works do, however, restrict what you may do
   with a derivative work (the GPL is a good example of a license that
   places restrictions on derivative works).

    Help! I can't get my driver to compile, what should I do?
    
   Thanks to Rust for putting together an answer for this question.
   
   First of all, learn how to redirect stderror to a file if you don't
   already know how, or at least find a computer where you can cut and
   paste. Then, you have 3 options for getting these errors to a more
   experienced driver person:
   
   * You can try The Idea Exchange a mud dedicated to mud development,
          where people who may be able to solve your problem, or at the
          very least you can post it to your target driver's newsgroup on
          The Idea Exchange, where they will be seen by knowlegeable
          people fairly quickly. In addition, for Lima specific compile
          problems, you can visit its support site Lima Bean
          (telnet://lima.imaginary.com:7878).
          
   * You can post it to rec.games.mud.lp, but don't cross post, and it
          probably wastes a lot more bandwidth on this newsgroup than on
          The Idea Exchange.
          
   * You can mail the maintainers of your driver:
          
          + CD: jacob@dd.chalmers.se
          + LPC4: hubbe@lysator.liu.se
          + LPMud 3.2: amylaar@cs.tu-berlin.de
          + MudOS: tim@handel.princeton.edu 
            
   For MudOS or DGD help, you are most likely to get a timely response by
   posting to the proper newsgroup on The Idea Exchange (ie.imaginary.com
   7890). For LPC4, your best bet is direct mail, for CD, either direct
   mail or visiting Genesis (hamal2.cs.chalmers.se 3011) and mailing
   Tintin et al.

    I have applied patch XXX, and now nothing works any more.
    
   _Answer from Joern Rennecke (Amylaar)_
   Have you supplied the proper -p option to patch? If not, you might end
   up with a patch applied to the wrong file. Check with the appropriate
   man page to "patch" for more details.

    How do I do ANSI colours?
    
   There are several misconceptions about colours. The first
   misconception is that all of the world is an IBM PC using ANSI style
   colours. In fact, there are many different sets of escape sequences
   which have the same effects depending on terminal emulation. If your
   goal is providing colour support to players, then limiting yourself to
   just ANSI support is very similar to saying "Only people with IBM
   compat's can play my mud." Well, maybe not quite that drastic, but you
   get the point.
   
   Also, you should keep in mind that the term ANSI has nothing to do
   with colours. ANSI is a standards organization, and one of the zillion
   things for which they have standards is escape sequences and what they
   do. Keep in mind that your goal is to have colours.
   
   Finally, about giving your mud colour support. The Discworld Mudlib
   has developed a protocol now supported by at least Dead Souls,
   Foundation, Lima, and TMI-2. There is no reason, however, that other
   libs cannot add support this protocol. It enables creators to code to
   a single set of codes and have those codes dynamically interpreted
   into colours proper to the terminal emulation being used by a given
   player. If a certain player has no colour support, that person does
   not see the colour codes. For more information on this protocol, stop
   by The Idea Exchange at ie.imaginary.com 7890.
     _________________________________________________________________
                                      
    Why not just hard code the colours?
    
   There are multiple colour escape sequence protocols. Some players
   cannot support colour escape sequences at all. Sending colour escape
   sequences to people who cannot handle them, or to people who use
   different protocols can mess up their displays severely, making the
   game unplayable.
     _________________________________________________________________
                                      
    How to I make the mud use vi/emacs instead of ed?
    
   This question gets asked constantly. When you come around to ask it,
   think about what exactly you want. Do you want to have vi or emacs on
   your mud? Or is it that you really want to have a convenient way of
   editing mud files (which ed certainly is not)? In truth, the real
   problem is the need for something more convenient than the very
   inconvenient ed which muds use. The kneejerk response to this need is
   the belief that your UNIX editing tools will solve this need. The fact
   is, however, there are better ways to accomplish this goal which are
   listed in Section III: Can I code offline?
   
   Not convinced? There are the technical reasons that people often give,
   such as the fact that any visual editor will require character mode,
   which is non-trivial in the current batch of muds and very network
   intensive. The bottom line as to why this is not generally done is
   that it provides nothing, yet costs a lot.
     _________________________________________________________________
                                      
    Is it possible to connect multiple muds together?
    
   Is it possible? Yes.
   
   Why do you want to connect muds? There are two common meanings behind
   this:
    1. Distributed mudding
    2. Connecting multiple muds
       
   Distributed mudding is basically a single mud whose resources are
   spread across multiple servers. Distributed anything is generally
   required of resource intensive, mission-critical applications. muds
   are not, in the scheme of things, resource intensive and they
   generally are not mission-critical applications. Distributed computing
   basically gives you the ability to expand horizontally rather than
   vertically. That means instead of buying yourself a sparc 20 to run
   your mud, you can architect it in such a way that two sparc 2
   computers will give the same performance.
   
   The fact of the matter, however, is that no mud currently in existence
   uses the resources which require this kind of scalability. In
   addition, most MUDs have a hard enough time finding one site, much
   less getting two.
   
   More commonly, however, people are thinking of the ability to connect
   multiple MUDs together. Before deciding this is a good thing, you
   should define the problem you want solved by connecting muds. As of
   yet, I have not heard a problem which connecting muds solves. The most
   vocal reason is to allow a person to have the same character across
   multiple muds. At that point, however, you have to define _what it is
   to be that person_. Most people will quickly say that what defines
   their character is that they control it. If that is the case, then
   connecting muds does not solve this problem. A client which allows the
   person to login to multiple muds is what solves this problem.
   
   The response then might be to have the same level/skills/whatever
   across the multiple muds. At this point, however, they cease to be
   multiple muds connected, but instead one huge distributed mud. This
   would be a poor way to design a distributed mud, and would also lead
   to political headaches and a huge waste of creative talent.

    Can a mud server run on DOS?
    
   Yes, most of the servers have DOS binaries available. In addition,
   most of the mudlibs have had their files arranged and ported so they
   fit in the FAT 8.3 naming scheme. If you wish to allow others access
   to the mud over modem lines, be sure to get the comdrv17.com file with
   your server and mudlib. For those who choose mudlibs with colours in
   them, the current batch of drivers was compiled in such a way that the
   drivers do not send output through ANSI.SYS (thus no colour).
