    This HOWTO is designed for people with experience in programming
    and some skills in managing a software project but who are new to
    the world of free software. This document is meant to act as a
    guide to the non-technical aspects of free software development
    and was written to act as a crash course in the people skills that
    aren't taught to commercial coders but that can make or break a
    free software project.

  <title>Introduction</title>
  
  <indexterm>
   <primary>fswd!introduction</primary>
  </indexterm>
  
  <para>
   Skimming through freshmeat.net provides mountains of reasons for this
   HOWTO's existence--the Internet is littered with excellently
   written and useful programs that have faded away into the Universe
   of Free Software Forgottenness. This dismal scene made me ask
   myself, "Why?"
  </para>

  <para>
   This HOWTO tries to do a lot of thing (probably too many), but it
   can't answer that question and won't attempt it. What this HOWTO
   will attempt to do is give your Free Software project a fighting
   chance--an edge. If you write a piece of crap that no one is
   interested in, you can read this HOWTO until you can recite it in
   your sleep and your project will probably fail. Then again, you can
   write a beautiful, relevant piece of software and follow every
   instruction in this HOWTO and your software may still not make
   it. Sometimes life is like that. However, I'll go out a limb and
   say that if you write a great, relevant pieces of software and
   ignore the advise in this HOWTO, you'll probably fail <emphasis>
   more often</emphasis>.
  </para>

  <para>
   A lot of the information in this HOWTO is best called common
   sense. Of course, as any debate on interfaces will prove, what is
   common sense to some programmers proves totally unintuitive to
   others. After explaining bits and pieces of this HOWTO to Free
   Software developers on several occasions, I realized that writing
   this HOWTO might provide a useful resource and a forum for
   programmers to share ideas about what has and has not worked for
   them.
  </para>

  <para>
   As anyone involved in any of what seems like an unending parade of
   ridiculous intellectual property clashes will attest to, a little
   bit of legalese proves important.

   <para>
    <emphasis>Karl Fogel</emphasis>, the author of <emphasis>Open
    Source Development with CVS</emphasis> published by the Coriolis
    Open Press. Large parts of his book are available <ulink
    url="http://cvsbook.red-bean.com">on the web</ulink>. 225 pages of
    the book are available under the GPL and constitute the best
    tutorial on CVS I've ever seen. The rest of the book covers, "the
    challenges and philosophical issues inherent in running an Open
    Source project using CVS." The book does a good job of covering
    some of the subjects brought up in this HOWTO and much
    more. <ulink url="http://cvsbook.red-bean.com">The book's
    website</ulink> has information on ordering the book and provides
    several translations of the chapters on CVS. I you are seriously
    interested in running a Free Software project, you want this
    book. I tried to mention Fogel in sections of this HOWTO where I
    knew I was borrowing directly from his ideas. If I missed any, I'm
    sorry, and I'll try and have those fixed in future versions.

   </para>

   <para>
    Also providing support material, and inspiration for this HOWTO is
    Eric S. Raymond for his prolific, consistent, and carefully
    crafted arguments, Lawrence Lessig for reminding me of the
    importance of Free Software. Additionaly, I want to thank every
    user and developer involved with the <ulink
    url="http://www.debian.org">Debian Project</ulink>. The project
    has provided me with a home, a place to practice Free Software
    advocacy, a place to make a difference, a place to learn from
    those how have been involved with the movement much longer than I,
    and proof of a Free Software project that definitely, definitely
    works.
   </para>

   <para>
    Above all, I want to thank <emphasis>Richard Stallman</emphasis>
    for his work at the Free Software Foundation and for never giving
    up. Stallman provides and articulates the philosophical basis that
    attracts me to Free Software and that drives me towards writing a

    afforded by a translated version.
   </para>

   <para>
    However, this HOWTO is still young and I have to yet to be
    contacted about a translation so English is all that is currently
    available. If you would like to help with or do a translation, you
    will gain my utmost respect and admiration and you'll get to be

 <sect1 id="starting">
  <title>Starting a Project</title>

   <indexterm>
    <primary>fswd!starting</primary>
   </indexterm>
  <para>
   With very little argument, the beginning is most difficult part of
   successful free software development. Laying a firm foundation will
   determine whether your project flourishes or withers away and
   dies. It is also the subject that is of most immediate interest to
   anyone reading this document as a tutorial.
  </para>

  <para>
   Starting a project involves a dilemma that you as a developer must
   try and deal with: No potential user for your program is interested
   in a program that doesn't work. Simultaneously, the development
   process that you want to employ holds involvement of users as
   prerequisit to working software.
  </para>

  <para>
   It is in these dangerous initial moments that anyone working to
   start a free software project must try and strike a balance along
   these lines. One of the most important ways that someone trying to
   start a project can work towards this balance is by establishing a
   solid framework for the development process through some of the
   suggestions mentioned in this section.
  </para>


<!-- Section2: chooseproject-->

  <sect2 id="chooseproject">
   <title>Choosing a Project</title>

   <para>
    If you are reading this document, there's a good chance you
    already have an idea for a project in mind. Chances are pretty
    good, it fills in a percieved gap by doing something that no other
    free software process does or by doing something in a way the is
    unique enough to necessitate a separate project.
   </para>

   <sect3 id=identifyidea>
    <title>Identify and articulate your idea</title>
    <para>
     Eric S. Raymond writes about how free software projects start in
     his paper, <quote>The Cathedral and the Bazaar,</quote> which
     comes as required reading for any free software development. It
     is available <ulink
     url="http://www.tuxedo.org/~esr/writings/cathedral-bazaar/">online
     </ulink>.
    </para>

    <para>
     In <quote>The Cathedral and the Bazaar,</quote> Raymond tells us
     that: <emphasis>Every good work of software starts by scratching
     a developers itch.</emphasis> Raymond's now widely accepted
     hypothesis is that new free software programs are written, first
     and foremost, to solve a specific problem facing the developer.
    </para>

    <para>
     If you have an idea for a program in mind, chances are good that
     it targets a specific problem or <quote>itch</quote> you want to
     see scratched. This idea is the project. Articulate it
     clearly. Write it out. Describe the problem you will attack in
     detail. The success of your project in tackling a particular
     problem will be tied to your ability to identify that problem
     early on. Find out exactly what it is that you want your project
     to do.

     Monty Manley articles the importance of this initial step in an
     essay, <ulink
     url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
     Projects the Open Source Way.</ulink> As the next section will
     show, there is <emphasis>a lot</emphasis> of work that needs to
     be done before software is ready for release. Manley says,
     <quote>Beginning an OSS project properly means that a developer
     must, first and foremost, avoid writing code too soon!</quote>
    </para>
   </sect3>

   <sect3 id=evalulateidea>
    <title>Evaluate your idea</title>

    <para>
     In evaluating your idea, you need to first ask yourself a few
     questions.  Before you move any further into this HOWTO, you need
     to determine if the free software development model really is the
     right one for your project. Obviously, since the program
     scratches your itch, you are definitely interested in seeing it
     implemented in code. But, because one hacker coding in solitude
     fails to qualify as a free software development effort, you need
     to ask yourself the question: <emphasis>Is anybody else
     interested?</emphasis>
    </para>

    <para>
     Sometimes the answer is a simple <emphasis>no</emphasis>. If you
     want to write a set of scripts to sort <emphasis>your</emphasis>
     <acronym>MP3</acronym> collection on your machine, maybe the free
     software development model is not the best one to
     choose. However, if you want to write a set of scripts to sort
     <emphasis>anyone's</emphasis> <acronym>MP3</acronym>s, a free
     software project might fill a useful gap.
    </para>

    <para>
     Luckily, The Internet is a place so big and so diverse that,
     chances are, there is someone, somewhere, who shares your
     interests and how feels the same <quote>itch.</quote> It is the
     fact that there are so many people with so many similar needs and
     desires that introduces the second major question: <emphasis>Has
     somebody already had your idea or a reasonably similar
     one?</emphasis>

    <sect4 id=evalhow>
     <title>Deciding to Proceed</title>
     <para>
      Once you have successful charted the terrain and have an idea
      bout what kinds of similar free software projects exist, every
      developer needs to decide whether to proceed with their own
      project. It is rare that a new project seeks to accomplish a
      goal that is not similar to or related to the goal of another
      project. Anyone starting a new project needs to ask themselves:
      <quote>Will the new project be duplicating work done by another
      project? Will the new project be competing for developers with
      an existing project? Can the goals of the new project be
      accomplished by adding functionality to an existing
      project?</quote>
     </para>

     <para>
      If the answer to any of these questions is <quote>yes,</quote>
      try to contact the developer of the existing project(s) in
      question and see if he or she might be willing to collaborate
      with you.
     </para>

     <para>
      This may be the single most difficult aspect of free software
      development for many developers but it is an essential one. It
      is easy to become fired up by an idea and be caught up in the
      momentum and excitement of a new project. It is often extremely
      difficult to do but, it is important that any free software
      developer remember that the best interests of the free software
      community and the quickest way to accomplish ones own project's
      goals and the goals of similar project can often be accomplished
      by <emphasis>not</emphasis> starting a new project.
     </para>

    </sect4>
   </sect3>
  </sect2>

<!-- Section2: naming-->

  <sect2 id="naming">
   <title>Naming your project</title>

   <para>
    While there are plenty of projects that fail with descriptive
    names and plenty that succeed without them, I think naming your
    project is wroth giving a little bit of thought. Leslie Orchard
    tackles this issue in a n <ulink
    url="http://www.advogato.org/article/67.html">advogato
    article</ulink>. The article is short and probably worth looking
    over quickly.
   </para>

   <para>
    The very short version is that Orchard recommends that you should
    pick a name where, after hearing the name, many users or
    developers will:
   </para>

   <para>
    <itemizedlist>
     <listitem>
      <para>You will know what the project does.</para>
     </listitem>
     <listitem>
      <para>You will remember it tomorrow.</para>
     </listitem>
    </itemizedlist>
   </para>

   <para>
    Humorously, Orchard's project, Iajitsu, does neither (and
    development is effectively frozen since the article was written).
   </para>

   <para>
    There is a point though. There are companies who only job is to
    make names for pieces of software. They make
    <emphasis>ridiculous</emphasis> amount of money doing it and they
    are supposedly worth it. While you probably can't aford a company
    like this, you can afford to learn from their existance and think
    a little bit about the name you are giving your project.
   </para>

   <para>
    If there is a name you really want, go ahead. I though
    <quote>gnubile</quote> was one of the best names ever and I still
    talk about it, long after I've stopped using the program. If you
    can flexible on the subject, listen to Orchard's advice. It might
    even help you.
   </para>
  </sect2>

<!-- Section2: licensing-->

  <sect2 id="licensing">
   <title>Licensing your Software</title>
   
   <para>
    On one (somewhat simplistic) level, the difference between a piece
    of free software and a piece of propriety software is the
    license. A license helps you as the developer by protecting your
    legal rights to have your software distributed under your terms
    and helps demonstrate to those who wish to help you or your
    project that they are encouraged to join.
   </para>
   
   <sect3 id="chooselicense">
    <title>Choosing a license</title>

    <para>
     Any discussion of licenses is also sure to generate at least a
     small flame war as there are strong feelings that some free
     software licenses are better than others. This discussion also
     brings up the question of <quote>Open Source Software</quote> and
     the debate around <quote>Open Source Software</quote> and
     <quote>Free Software</quote>. However, because I've written the
     Free Software Development HOWTO and not the Open Source
     Development HOWTO, my own allegiances in this argument are in the
     open.
    </para>

    <para>
     In attempting to reach a middle ground through diplomacy without
     sacrificing my own philosophy, I recommend picking any license
     that conforms to the <ulink

    <para>
     In attempting a more in-depth analysis, I agree with Karl Fogel's
     description of licenses as falling into two groups: those that
     are the <acronym>GPL</acronym> and those that are not the
     <acronym>GPL</acronym>.
    </para>

    <para>
     Personally, I license all my software under the
     <acronym>GPL</acronym>. Created and protected by the Free
     Software Foundation and the GNU Project, the
     <acronym>GPL</acronym> is the license for the Linux kernel,
     GNOME, Emacs, and the vast majority of GNU/Linux software. It's
     the obvious choice but I believe it is a good one. Any BSD
     fanatic will urge you to remember that there is a viral aspect to
     the <acronym>GPL</acronym>that prevents the mixture of
     <acronym>GPL</acronym>'ed code with non-<acronym>GPL</acronym>'ed
     code. To many people (myself included), this is a benefit, but to
     some, it is a major drawback.

   <title>Choosing a Method of Version Numbering</title>

   <para>
    <emphasis>The most important thing about a system of version
    numbering is that there is one.</emphasis> It may seem pedantic to
    emphasize this point but you'd be surprised at the number of
    scripts and small programs that pop up without any version number
    at all.
   </para>

   <para>
    <emphasis>The second most important thing about a system of
    numbering is that the numbers always go up.</emphasis> Automatic
    version tracking systems and people's sense of order in the
    universe will fall apart if version numbers don't rise. It doesn't
    <emphasis>really</emphasis> matter if 2.1 is a big jump and
    2.0.005 is a small jump but it does matter that 2.1 is more recent
    than 2.0.005.
   </para>

   <para>
    Beyond this, the most common technique seems to be the
    <quote>major level</quote>, <quote>minor level</quote>,
    <quote>patch level</quote> version numbering scheme. Whether you
    are familiar with it or not, you interact with it all the
    time. The first number is the major number and it signifies major
    changes or rewrites. The second number is the minor number and it
    represents added or tweaked functionality on top of a largely
    coherant structure. The third number is the patch number and it
    usually will only refer to bug fixes.
   </para>

   <para>
    The widespread use of this scheme is why I know the nature and
    relative degree in the differences between a 2.4.12 release of the
    Linux kernel and a 2.4.11, 2.2.12, and 1.2.12 without knowning
    anything about any of the releases.
   </para>

   <para>
    You can bend or break these rules, and people do. Beware, if you
    choose to, someone will get annoyed, assume you don't know, and
    try and educate you. I always follow this method and I implore you
    to do so as well.
   </para>
 
   <para>
    Follow these two simple rules and you will not go (too)
    wrong. Still, there are several version numbering systems that are
    well known, useful, and that might be worth looking into before
    you release your first version.
   </para>

   <variablelist>
    <varlistentry>
     <term>Linux kernel version numbering:</term>
     <listitem>
      <para>The Linux kernel uses a versioning system where any odd
      minor version number refers to an development or testing release
      and any even minor version number refers to a stable
      version. Think about it for a second. Under this system, 2.1 and
      2.3 kernels were and always will be development or testing
      kernels and 2.0, 2.2. and 2.4 kernels are all production code
      with a higher degree of stability and more testing.
     </para>

      <para>
       Whether you plan on having a split development model (as
       described in <xref linkend="branches">) or only one version
       released at a time, my experience with several free software
       projects and with the Debian project has taught me that use of
       Linux's version numbering system is worth taking into
       consideration. In Debian, all minor versions are stable
       distributions (2.0, 2.1, etc). However, many people assume that
       2.1 is an unstable or development version and continue to use
       an older version until they get so frustrated with the lack of
       progress development that they complain and figure the system
       out. If you never release an odd minor version but only release
       even ones, nobody is hurt, and less people are confused. It's
       worth taking into consideration.

      <para>Because of the unusual nature of wine's development where
      the not-emulator is constantly improving but not working towards
      any immediately achievable goal, wine is released every three
      weeks. Wine does this by labeling their releases in Year Month
      Day format where each release might be labeled
      <quote>wine-XXXXXXXX</quote> where the version from January 04,
      2000 would be <quote>wine-20000104</quote>. For certain

      complex free software model available. Their version numbering
      has reflected the unique situation in which it is
      developed.
      </para>

      <para>
       Mozilla's version numbering structure has historically been
       made up of milestones. From the beginning of the mozilla
       project, the goals of the project in the order and degree to
       which they were to be achieved were charted out on a series of
       <ulink url="http://www.mozilla.org/roadmap.html">road
       maps</ulink>. Major points and achievements along these
       road-maps were marked as milestones. Therefore, mozilla was
       built and distributed nightly as "nightly builds" but on a day
       when the goals of a milestone on the road-map had been reached,
       that particular build was marked as a milestone release.
      </para>

      <para>
       While I haven't seen this method employed in any other projects
       to date, I like the idea and think that it might have value in
       any testing or development branch of a large free application
       under heavy development.

   <title>Documentation</title>

   <para>
    A huge number of otherwise fantastic free software applications
    have withered and died because their author was the only person
    who knew how to use them fully. Even if your program is written
    primarily for a techno-savvy group of users, documentation is
    helpful and even necessary for the survival of your project. You
    will learn later in <xref linkend="releasing"> that you should
    always release something that is usable. <emphasis>A piece of
    software without documentation is not usable.</emphasis>
   </para>

   <para>
    There are lots of different people for whom to document and
    therefore there are lots of ways to document your
    project. <emphasis>The importance of ocumentation in source code
    to help facilitate development by a large community is vital but
    it falls outside the scope of this HOWTO.</emphasis> This being
    the case, this section deals mostly useful tactics for
    user-directed documentation.
   </para>

   <para>
    A combination of tradition and necessity has resulted in a
    semi-regular system of documentation in most free software
    projects that is worth following. Both users and developers expect
    to be able to get documentation in several ways and it's essential
    that you provide the information they are seeking in a form they
    can read if your project is ever going to get off the
    ground. People have come to expect:
   </para>

   <sect3>
    <title>Man pages</title> 

    <para>Your users will want to be able to type <quote>man
    projectname</quote> end up with a nicely formatted man page
    highlighting the basic use of yourapplication. Make sure that
    before you release your program, you've planned for this.
    </para>

    <para>
     Man pages are not difficult to write. There is excellent
     documentation on the man page writing process available through the
     <quote>The Linux Man-Page-HOWTO</quote> available through the
     Linux Documentation project <acronym>(LDP)</acronym> written by
     Jens Schweikhardt. It is available <ulink

     Schweikhardt's site</ulink> or <ulink

     <acronym>LDP</acronym></ulink>.
    </para>

    <para>
     It is also possible to write man pages using DocBook SGML and
     convert them into man pages. Because man pages are so simple and
     the DocBook method relatively new, I have not been able to follow
     this up but would love help from anyone who can give me more
     information on how exactly this is done.

    <title>Command line accessible documentation</title>

    <para>
     Most users will expect some basic amount of documentation to be
     easily available from the command line. For few programs should
     this type of documentation extend for more than one screen (24 or
     25 lines) but it should cover the basic usage, a brief (one or
     two sentence) description of the program, a list of the commands
     with explanations, all the major options (also with
     explanations), and a pointer to more in-depth documentation for
     those who need it. The command line documentation for Debian's
     apt-get serves as an excellent example and a useful model:
    </para>

    <screen>
apt 0.3.19 for i386 compiled on May 12 2000  21:17:27
Usage: apt-get [options] command
       apt-get [options] install pkg1 [pkg2 ...]

apt-get is a simple command line interface for downloading and
installing packages. The most frequently used commands are update
and install.

Commands:
   update - Retrieve new lists of packages
   upgrade - Perform an upgrade
   install - Install new packages (pkg is libc6 not libc6.deb)
   remove - Remove packages
   source - Download source archives
   dist-upgrade - Distribution upgrade, see apt-get(8)
   dselect-upgrade - Follow dselect selections
   clean - Erase downloaded archive files
   autoclean - Erase old downloaded archive files
   check - Verify that there are no broken dependencies

Options:
  -h  This help text.
  -q  Loggable output - no progress indicator
  -qq No output except for errors
  -d  Download only - do NOT install or unpack archives
  -s  No-act. Perform ordering simulation
  -y  Assume Yes to all queries and do not prompt
  -f  Attempt to continue if the integrity check fails
  -m  Attempt to continue if archives are unlocatable
  -u  Show a list of upgraded packages as well
  -b  Build the source package after fetching it
  -c=? Read this configuration file
  -o=? Set an arbitary configuration option, eg -o dir::cache=/tmp
See the apt-get(8), sources.list(5) and apt.conf(5) manual
pages for more information and options.
    </screen>

    <para>
     It has become a GNU convention to make this type of information
     accessible with the <quote>-h</quote> and the
     <quote>--help</quote> options. Most GNU/Linux users will expect
     to be able to retrieve basic documentation these ways so if you
     choose to use different method, be prepared for the flames and
     for the fallout that may result.

     In addition to man pages and command-line help, there are certain
     files where people will look for documentation, especially in any
     package containing source code. In a source distribution, most of
     these files can be stored in a the root directory of the source
     distribution or in a subdirectory of the root called
     <quote>doc</quote> or <quote>Documentation</quote>. Common files
     places in these places include:

        instructs the user to run <quote>./configure; make; make
        install</quote> and touches on any unusual options or actions
        that may be necessary. More advanced users can usually avoid
        INSTALL files but it's good practice to at least glance at one
        to understand what can be expected. For most relatively
        standard install procedures and for most programs, INSTALL
        files are as short as possible are rarely over 100

        to simply keep a file with the source code for your program
        and add a section to the top of the changelog with each
        release describing what has been, changed, fixed, or added to
        the program. It's a good idea to post the changelog onto the
        website as well because it can help people decide whether they

     Package formats may differ depending on the system you are

     usually serve as the package format of choice. If you are
     developing for GNU/Linux, *BSD, or any UN*X, make sure that your
     source code is always available in tar'ed and gzip'ed format
     (.tar.gz). UNIX compress (.Z) has gone out of style and
     usefulness and faster computers have brought bzip2 (.bz2) into
     the spot-lit as a more effective compression medium. I now make
     all my releases available in both gzip'ed and bzip2'ed formats.

     Binary packages are largely distribution specific. You can build
     binary packages against a current version of a major
     distribution, you will only make your users happy. Try to foster
     relationships with users or developers of large distribution to
     develop a system for consistent binary packages. It's often a
     good idea to provide RedHat <acronym>RPM</acronym>'s (.rpm),
     Debian deb's (.deb) and source <acronym>RPM</acronym>'s
     <acronym>SRPM</acronym>'s. Binary packages can also be compiled
     against a specified system with specified libraries and
     distributed in tar.gz format as well. <emphasis>Remember: While
     these binaries packages are nice, getting the source packaged and
     released should always be your priority. Your users or fellow
     developers can and will do the the binary packages for
     you.</emphasis>

     A version control system can make a lot of these problems of
     packaging (and a lot of other problems mentioned in this HOWTO)
     much easier. If you are using *NIX, CVS is your best bet. I
     recommend Karl Fogel's book on the subject (and the <ulink

     wholeheartedly.

    <para>
     CVS or not, you should probably invest some time into learning
     about a version control system because it provides an automated
     way of solving many of the problems introduced into this HOWTO.
     I am not aware of any free version control systems for windows or
     mac but I know that CVS clients exist for both
     platforms. Websites like <ulink

     as well with a nice, easy to use interface to CVS.

     I'd love to devote more space in this HOWTO to CVS because I love

     already have its own HOWTO written about it.

   Once you have gotten your project started, you have overcome the
   most difficult hurdles in the development process of your
   program. Laying a firm foundation is essential, but the development
   process itself is equally important and provides quite a few
   opportunities for failure. In the next two sections, I will cover
   running a project by discussing how to maintain a project through
   interactions with developers and with users.

   In releasing your program, your program becomes free software. This
   transition is more than just a larger user base. By releasing your
   program as free software, <emphasis>your</emphasis> software
   becomes the <emphasis>free software community's</emphasis>
   software. The direction of your software's development will be
   reshaped, redirected, and fully determined by your users and, to a
   larger extent, by other developers in the community.
  </para>

  <para>
   The major difference between free software development and
   propriety software development is the developer base. As the leader
   of a free software project, you need to attract and keep developers
   in a way that leaders of proprietary software projects simply don't
   have to worry about. <emphasis>As the person leading development of
   a free software project, you must harness the work of fellow
   developers by making responsible decisions and by responsibly
   choosing not to make decisions. You have to direct developers
   without being overbearing or bossy. You need to strive to earn
   respect and never forget to give it out.</emphasis>

    By now, you've hypothetically followed me through the early

    system of documentation and and we've gone ahead and (as will be
    discussed in <xref linkend="releasing">) released it to the rest

   <para>
    Delegation is the political way of describing this process of
    <quote>letting go.</quote> It is the process of handing some of
    the responsibility and power over your project to other responsible
    and involved developers. It is difficult for anyone who has
    invested a large deal of time and energy into a project but it
    essential for the growth of any free software project. One person
    can only do so much. A free software project is nothing
    without the involvement of a group of developers. A group of
    developers can only be maintained through respectful and
    responsible leadership and delegation.
   </para>

   <para>
    As your project progresses, you will notice people who are putting
    significant amounts of time and effort into your project. These
    will be the people submitting the most patches, posting most on
    the mailing lists, engaging in long email discussions. It is your
    responsibility to contact these people and to try and shift some of
    the power and responsibility of your position as the project's
    maintainer onto them (if they want it). There are several easy
    ways you can do this:

   <para>
    In a bit of a disclaimer, delegation need not mean rule by
    comittee. In many cases it does and this has been proven to
    work. In other cases this has been the death of a project. <ulink

    projects do best when one person is the clear leader of a team and
    makes the big decisions (design changes, release dates, and so
    on).</quote> I think this often true but would urge developers to
    consider the ideas that the project leader need not be the
    projects founder and that these important powers need not all rest
    in one person but that a release manager may be different than a
    lead developer. These situations are tricky politically though so
    be careful and make sure this is necessary before you go around
    empowering people.

    <title>How to delegate</title>
 
    <para>
     You may find that other developers seem even more experienced or
     knowledgeable than you. Your job as a maintainer does not mean
     you have to have to be the best or the brightest. It means you
     need are responsible for showing good judgment and for
     recognizing which solutions are maintainable and which are not. 
    </para>
    <para>
     Like anything, its easier to watch others delegate than to do it
     yourself. In a sentence: <emphasis>Keep an eye out for other
     qualified developers who show an interest and sustained

     towards them.</emphasis> The following ideas might be good places
     to start or good sources of inspiration:

     <para>
      <ulink url="http://httpd.apache.org/">Apache</ulink> is an
      example of a project that is run by small group of developers
      who vote on major technical issues and the admission of new

     <para>
      The <ulink url="http://www.debian.org/"> Debian Project</ulink>
      is an extreme example of rule by committee. At current count,
      more than 700 developers have full responsibility for certain
      aspects of the projects. All these developers can upload into
      the main FTP servers, and vote on major issues. Direction for
      the project is determined by the project's <ulink
      url="http://www.debian.org/social_contract">social
      contract</ulink> and a <ulink

      is to, <quote>Appoint Delegates or delegate decisions to the

     <para>
      While both of these projects operate on a scale that your
      project will not (at least initially), their example is
      helpful. Debian's idea of a project leader who can do
      <emphasis>nothing</emphasis> but delegate serves as a
      caricature of how a project can involve and empower a huge
      number of developers and grow to a huge size.

      This use of the release manager is a good way to give yourself a

    </para>

     These are the criteria that you as a project maintainer should
     take into account each time you receive a patch.
    </para>

    <para>
     Fogel elaborates on this again and states the <quote>the
     questions to ask yourself when considering whether to implement
     (or approve) a change are:</quote>

    <para>

      <listitem>
       <para>Will it benefit a significant percentage of the program's

     The answers to these questions are never straightforward and its
     very possible (and even likely) that the person who submitted the
     patch may feel differently about the answer to those questions
     than you do. However, if you feel that that the answer to either
     of those questions is <quote>no,</quote> it is your responsibility
     to reject the change. If you fail to do this, the project will
     become unwieldy and unmaintainable and will ultimately fail.

   <sect3>
    <title>Rejecting patches</title>

    <para>
     Rejecting patches is probably the most difficult and the most
     sensitive job that the maintainer of any free software project
     has to face. But sometimes it has to be done. I mentioned earlier
     (in <xref linkend="developers"> and in <xref
     linkend="delegation">) that any developer needs to try and
     balance your responsibility and power to make what you think are
     the best technical decisions with the fact that you will lose
     support from other developers if you seem like you are on a power
     trip or being overly bossy or possessive of a community-based
     project. I recommend that you keep three major facts in mind when
     rejecting patches (or other changes):
    </para>

    <sect4>
     <title>Bring it to the community</title>
     <para>
      One of the best ways of justifying a decision to reject a patch
      and working to not seem like you keep an iron grip on your
      project is by not making the decision alone at all. It might
      make sense to turn over larger proposed changes or more
      difficult decisions to a development mailing list where they can
      be discussed. There will be some patches (bug fixes, etc.) which
      will definitely be accepted and some that you feel are so off
      base that they do not even merit further discussion. It is those
      that fall into the grey area between these two groups that might
      merit a quick forward to a mailing list.
     </para>

     <para>
      I recommend this process wholeheartedly. As the project
      maintainer you are worried about making the best decision for
      the project, for the project's users and developers, and for
      yourself as a responsible project leader. Turning things over to
      an email list will demonstrate your own responsibility and
      responsive leadership as it tests and serves the interests of
      your software's community.
     </para>
    </sect4>

    <sect4>
     <title>Technical issues are not always good justification</title>
     <para>
      Especially towards the beginning, you will find that many
      changes are difficult to implement, introduce new bugs, or have
      other technical problems. Try to see past these. Especially with
      added functionality, good ideas do not always come from good
      coders. Technical merit is a valid reason to postpone an
      application of a patch but it is not always a good reason to
      reject a change outright. Even small changes are worth the
      effort of working with the developer submitting the patch to
      iron out bugs and incorporate the change if you thing you think
      it seems like a good addition to your project. The effort on
      your part will work to make your project a community project and
      it will pull a new or less experienced developer onto your
      project and even teach them something that might help them in
      making their next patch.
     </para>
    </sect4>

    <sect4>
     <title>Common courtesy</title>
     <para>
      It should go without saying but, <emphasis>above all and in all
      cases, just be nice.</emphasis> If someone has an idea and cares
      about it enough to write some code and submit a patch, they
      care, they are motivated, and they are already involved. Your
      goal as the maintainer is make sure they submit again. They may
      have thrown you a dud this time but next time may be the idea or
      feature that revolutionizes your project. 
     </para>

     <para>
      It is your responsibility to first justify your choice to not
      incorporate their change clearly and concisely. Then thank
      them. Let them know that you a appreciate their help and feel
      horrible that you can't incorporate their change. Let them know
      that you look forward to their staying involved and you hope
      that the next patch or idea meshes better with your project
      because you appreciate their work and want to see it in the
      project. If you have ever had a patch rejected after putting a
      large deal of time, thought, and energy into it, you remember
      how it feels and it feels bad. Keep this in mind when you have
      to let someone down. It's never easy but you need to do
      everything you can to make it as not-unpleasant as possible.

<!-- Section2: branches  -->

  <sect2 id="branches">
   <title>Stable and Development Branches</title>

   <para>
    The idea of stable and development branches has already been
    described briefly in <xref linkend="chooseversioning"> and in
    <xref linkend="delegatebranch">. These allusions attest to some of
    the ways that multiple branches can affect your software. Branches
    can let you avoid (to some extent) some of the problems around
    rejecting patches (as described in <xref linkend="patching">) by
    allowing you to temporarily compromise the stability of your
    project without affecting those users who need that stability.
   </para>

   <para>
    The most common way of branching your project is to have one
    branch that is stable and one that is for development. This is the
    model followed by the Linux kernel that is described in <xref
    linkend="chooseversioning">. In this model, there is always one
    branch that is stable and always one that is in
    development. Before any new release, the development branch goes
    into a <quote>feature freeze</quote> as described in <xref
    linkend="freezing"> where major changes and added features are
    rejected or put on hold under the development kernel is released
    as the new stable branch and major development resumes on the
    development branch. Bug fixes and small changes that are unlikely
    to have any large negative repercussions are incorporated into the
    stable branch as well as the development branch.
   </para>

   <para>
    Linux's model is an extreme one. On many projects, there is no
    need to have two versions always available. It may make sense to
    have two versions only near a release. The Debian project has
    historically made both a stable and an unstable distribution
    available but has expanded to this to include: stable, unstable,
    testing, experimental, and (around release time) a frozen
    distribution that only incorporates bug fixes during the
    transition from unstable to stable. There are few projects whose
    size would necessitate a system like Debian's but this use of
    branches helps demonstrate how they can be used to balance
    consistent and effective development with the need to make regular
    and usable releases.
   </para>

   <para>
    In trying to set up a development tree for yourself, there are
    several things that might be useful to keep in mind:
   </para>

   <para>
    <variablelist>

     <varlistentry>
      <term>Minimize the number of branches</term>
      <listitem>
       <para>Debian may be able to make good use of four or five
       branches but it contains gigabytes of software in over 5000
       packages compiled for a 5-6 different architectures. For you,
       two is probably a good number. Too many branches will confuse
       your users (I can't count how many times I had to describe
       Debian's system when it only had 2 and sometimes 3 branches!),
       potential developers and even yourself. Branches can help but
       they come at a cost so use them very sparingly.</para>
      </listitem>
     </varlistentry>

     <varlistentry>
      <term>Make sure that all your different branches are explained</term>
      <listitem>
       <para>As I mentioned in the preceding paragraph, different
       branches <emphasis>will</emphasis> confuse your users. Do
       everything you can to avoid this by clearly explaining the
       different branches in a prominent page on your website and in a
       Readme file in the <acronym>FTP</acronym> or
       <acronym>HTTP</acronym> directory.</para>

       <para>
        I might also recommend against a mistake that I think Debian
        has made. The terms <quote>unstable,</quote>
        <quote>testing,</quote> and <quote>experimental</quote> are
        vague and difficult to rank in order of stability (or
        instability as the case may be). Try explaining to someone
        that <quote>stable</quote> actually means <quote>ultra
        stable</quote> and that <quote>unstable</quote> doesn't
        actually include any unstable software but is really stable
        software that is untested as a distribution.
       </para>

       <para>
        If you are going to use branches, especially early on, keep in
        mind that people are conditioned to understand the terms
        <quote>stable</quote> and <quote>development</quote> and you
        probably can't go wrong with this simple and common division of
        branches.
       </para>
      </listitem>
     </varlistentry>

     <varlistentry>
      <term>Make sure all your branches are always available</term>
      <listitem>
       <para>Like a lot of this document, this should probably should
       go without saying but experience has taught me that it's not
       always obvious to people. It's a good idea to physically split
       up different branches in different directories or directory
       trees on your <acronym>FTP</acronym> or <acronym>HTTP</acronym>
       site. Linux accomplishes this by having kernels in a v2.2 and a
       v2.3 subdirectory where it is immediately obvious (after you
       know their version numbering scheme) which directory is for the
       most recent stable and the current development releases. Debian
       accomplishes this by naming all their distribution with names
       (i.e. woody, potato, etc.) and then changing symlinks named
       <quote>stable,</quote> <quote>unstable</quote> and
       <quote>frozen</quote> to point to which ever distribution (by
       name) is in whatever stage. Both methods work and there are
       others. In any case, it is important that different branches
       are always available, are accessible from consistent locations,
       and that different branches are clearly distinguished from each
       other so your users know exactly what they want to be
       downloading and where to get it.</para>

   <title>Other Development issues</title>
   <para>
    There are more issues surrounding interaction with developers in a
    free software project that I can not touch on in great detail in a
    HOWTO of this size. Please don't hesitate to contact me if you see
    any major omissions.
   </para>

   <para>
     Other smaller issues that are worth mentioning are:
   </para>

   <sect3 id="freezing">
    <title>Freezing</title>
    <para>
     For those projects that choose to adopt a split development model
     (<xref linkend="branches">), freezing is a concept that is worth
     becoming familiar with. 
    </para>

    <para>
     Freezes come in two major forms. A <quote>feature freeze</quote>
     is a period when no significant functionality is added to a
     program. It is a period where established functionality (even
     skeletons of barely working functionality) can be improved and
     perfected. It is a period where bugs are fixed. This type of
     freeze is usually applied some period (a month or two) before a
     release. It is easy to push a release back as you wait for
     <quote>one more feature</quote> and a freeze helps to avoid this
     situation by drawing the much needed line in the sand. It gives
     developers room they need to get a program ready for release.
    </para>

    <para>
     The second type of freeze is a <quote>code freeze</quote> which
     is much more like a released piece of software. Once a piece of
     software has entered a code freeze, all changes to the code are
     frowned upon and only changes that fix known bugs are
     permitted. This type of freeze usually follows a <quote>feature
     freeze</quote> and directly precedes a release. Most released
     software is in what could be interpreted as a sort of high
     level<quote>code freeze.</quote>
    </para>

    <para>
     Even if you never choose to appoint a release manager (<xref
     linkend="releasemanager">), you will have an easier time
     justifying the rejection or postponement of patches (<xref
     linkend="patching"> before a release with a publicly stated
     freeze in effect.
    </para>

   <sect3>
    <title>Forking</title>
    <para>
     Forks are the most extreme version of a branch. A fork is
     when a group of developers takes code from a free software
     project and actually starts a brand new free software
     project. The most famous example of a fork is Emacs and
     XEmacs. Both emacsen are based on an almost identical code-base
     but for technical, political, and philosophical reasons,
     development was split into two projects which now compete with
     each other.
    </para>

    <para>
     The short version of the fork section is, <emphasis>don't do
     them.</emphasis> Forks force developers to choose one project to
     work with, cause nasty political divisions and redundancy of
     work.  Luckily, usually the threat of the fork is enough to scare
     the maintainer or maintainers of a project into changing the way
     they run their project to avoid it.
    </para>

    <para>
     In his chapter on <quote>The Open Source Process,</quote> Karl
     Fogel describes how to do a fork if you absolutely must. If you
     have determined that is absolutely necessary and that the
     differences between you and the people threatening to fork are
     absolutely unresolvable, I recommend Fogel's book as a good place
     to start.

  <title>Maintaining a Project: Interacting with Users</title>
  <indexterm>
   <primary>fswd!users</primary>
  </indexterm>

  <para>
   If you've worked your way up to here, congratulations, you are
   nearing the end of this document. This final section describes some
   of the situations in which you, in your capacity as project
   maintainer, will be interacting with users. It gives some
   suggestions on how these situations might be handled effectively.
  </para>

  <para>
   Interacting with users is difficult. In our discussion of
   interaction with developers, the underlying assumption is that in a
   free software project, a project maintainer must constantly strive to
   attract and keep developers who can easily leave at any time.
  </para>

  <para>
   Users in the free software community are different than developers
   and are also different than users in the world of proprietary
   software and they should be treated differently than either
   group. Some ways in which the groups differ significantly follow:
  </para>

  <para>
   <itemizedlist>

    <listitem>
     <para>The lines between users and developers are blurred in ways
     that is totally foreign to any proprietary development
     model. Your users are often your developers and vice
     versa.</para>
    </listitem>

    <listitem>
     <para>In the free software world, you are often your users only
     choice. Because there is such an emphasis on not replicating the
     work of others in the free software community and because the
     element of competition present in the propriety software model is
     absent (or at least in an extremely different form) in the free
     software development model, you will probably be the only project
     that does what you do (or at least the only one that does what
     you do in the way that you do it). This means your responsiveness
     to your users is even more important than in the proprietary
     software world.</para>
    </listitem>

    <listitem>
     <para>In an almost paradoxical situation, free software projects
     have less immediate or dire consequences for ignoring their users
     altogether--it is also often easier to do. Because you don't
     usually need to compete with another product in the free software
     model, chances are good that you will not be scrambling to gain
     the features of the competitor's newest program. This means that
     your development process will have to be directed either
     internally, by a commitment to your users or by both.</para>
    </listitem>
   </itemizedlist>
  </para>

  <para>
   Trying to tackle this unique situation can only be done
   indirectly. Developers and maintainers need to listen to users and
   to try and be as responsive as possible. A solid knowledge of the
   situation recounted above is any free software developer's best tool
   for shifting his development or leadership style to fit the unique
   process of free software development. This chapters will try and
   introduce some of the more difficult or important points in any
   projects interactions with users and give some hints on how to
   tackle these.

   <title>Testing and Testers</title>

   <para>
    In addition to your users being your developers, they are also
    (and perhaps more commonly) your testers. Before I get flamed, I
    should rephrase my sentence: <emphasis>some</emphasis> of your
    users are your testers.
   </para>

   <para>
    It is important that this distinction be made early on because not
    all of your users want to be testers. Many users want to use
    stable software and don't care if they don't have the newest
    greatest software with the latest and greatest features. These
    users except a stable, tested piece of software with major or
    obvious bugs worked out or openly declared and will be angry if
    they find themselves in a testing position. This is yet another
    way in which a split development model (as mentioned in <xref

    <title>Automated testing</title>
    <para>
     For many programs, many common mistakes can be caught by
     automated means. Automated tests tend to be pretty good at
     catching errors that you've run into several times before or
     something you just forget. They are not very good at finding
     errors, even major ones, that were totally unforeseen.
    </para>

    <para>
     CVS comes with a bourne shell script called sanity.sh that is
     worth looking at. Debian uses a program called lintian that
     checks Debian packages for all of the most common errors. While
     use of these scripts may not be possible, there is a host of
     other sanity checking software on the net that may be applicable
     (feel free to email any recommendations). None of these will
     create a bug-free release but they will avoid at least some major
     oversights. Finally, if your programs become a long term
     endeavor, you will find that there are certain errors that you
     tend to make over and over. Start a collection of scripts that
     check for these errors to help prevent them in the future.
    </para>
   </sect3>

   <sect3>
    <title>Testing by testers</title>
    <para>
     For any program that depends on user interactivity, many bugs
     will only be uncovered through testing by users actually clicking
     the keys and pressing the mouse buttons. For this you need
     testers and as many testers as possible.
    </para>

    <para>
     The most difficult part of testing is finding testers. It's
     usually a good tactic to post a message to a relevant mailing
     list or news group announcing a specific proposed release date
     and outline the functionality of the program. If you put some
     time into the announcement, you are sure to get a few bites.
    </para>

    <para>
     The second most difficult part of testing is keeping your testers
     and keeping them actively involved in the testing
     process. Fortunately, there are some tried and true tactics that

        what you are looking for to each tester and make the means for
        reporting bugs simple and well established. The key is to
        provide as much structure as possible to make your testers'

   <title>Setting up Support Infrastructure</title>

   <para>
    While testing is important, the large part of your interactions
    and responsibility to your users falls under the category of
    support. The best way to make sure your users are adequately
    supported in using your program is to set up a good infrastructure
    for this purpose so that your developers and users help each other
    and less of the burden falls on you. This way, people will also
    get quicker and better responses to their questions. This
    infrastructure comes in several major forms:
   </para>

   <sect3>
    <title>Documentation</title>
    <para>
     It should not come as any surprise that the key element to any
     support infrastructure is good documentation. This topic was
     large covered in <xref linkend="documentation"> and will not be
     repeated here.
    </para>
   </sect3>

   <sect3>
    <title>Mailing lists</title>
    <para>
     Aside from documentation, effective mailing lists will be your
     greatest tool in providing user support. Running a mailing list
     well is more complicated than installing mailing list software
     onto a machine.
    </para>

    <sect4>
     <title>Separate lists</title>
     
     <para>
      A good idea is too separate your user and development mailing
      lists (perhaps into project-user@host and project-devel@host)
      and enforce the division. If people post a development question
      onto -user, politely ask them to repost it onto -devel and vise
      versa. Subscribe yourself to both groups and encourage all
      primarily developers to do the same.
     </para>

     <para>
      This system provides that no one person is stuck doing all of
      the support work and works so that users learn more about the
      program, they can help newer users with their questions.
     </para>
    </sect4>

    <sect4>
     <title>Choose mailing list software well</title>
     <para>
      Please don't make the selection of mailing list software
      impulsively. Please consider easy accessibility by users without
      a lot of technical experience so you want to be as easy as
      possible. Web accessibility to an archive of the list is also
      important.
     </para>

     <para>
      The two biggest free software mailing list programs are <ulink
      url="http://www.greatcircle.com/majordomo/">majordomo</ulink>
      and <ulink url="http://www.list.org/">GNU Mailman</ulink>. A
      long time advocate of majordomo, I would now recommend any
      project choose GNU Mailman. It fulfills the criteria listed
      above and makes it easier to do so. It provides a good mailing
      list program for a free software project maintainer as opposed
      to a good mailing list application for a mailing list
      administrator.
     </para>

     <para>
      There are other things you want to take in setting up your
      list. If it is possible to gate your mailing lists to USENET and
      provide them in digest form as well as making them accessible on
      the web, you will please some users and work to make the support
      infrastructure slightly more accessible.
     </para>
    </sect4>
   </sect3>

   <sect3>
    <title>Other support ideas</title>

    <para>
     A mailing list and accessible documentation are far from all you
     can do to set up good user support infrastructure. Be
     creative. If you stumble across something works well, email me
     and I'll include it here in the HOWTO.
    </para>

    <sect4>
     <title>Make your self accessible</title>
     <para>
      You can not put to few methods to access you. If you hang out in
      an <acronym>IRC</acronym> channel, don't hesitate to list in
      your projects documentation. List email and snail mail
      addresses, or ways to reach you via <acronym>ICQ</acronym>,
      <acronym>AIM</acronym>, or Jabber.
    </para>
    </sect4>

    <sect4>
     <title>Bug management software</title>
     <para>
      For many large software projects, use of bug management software
      is essential to keep track of which bugs have been fixed, which
      bugs have not been fixed, and which bugs are being fixed by
      which people. Debian uses the <ulink
      url="http://bugs.debian.org">Debian Bug Tracking System</ulink>
      (<acronym>BTS</acronym>) although it may not be best choice for
      every project (it seems to currently be buckling under its own
      weight. As well as a damn good web browser, the mozilla project
      has spawned a sub-project resulting in a bug tracking system
      called <ulink
      url="http://www.mozilla.org/projects/bugzilla/">bugzilla</ulink>
      which has become extremely possible and which I like quite a
      bit.
     </para>

     <para>
      These systems (and others like them) can be unwieldy so
      developers should be careful to not spend more time on the bug
      tracking system than on the bugs or the projects themselves. If
      a project continues to grow, use of a bug tracking system can
      provide an easy standard way for users and testers to report
      bugs and for developers and maintainers to fix them and track
      them in an orderly fashion.
     </para>

<!-- Section2: releasing -->

  <sect2 id="releasing">
   <title>Releasing Your Program</title>

   <para>
    As mentioned earlier in the HOWTO, the first rule of releasing is,
    <emphasis>release something useful.</emphasis> Non-working or
    not-useful software will not attract anyone to your
    project. People will be turned off of your project and be likely
    to simply gloss over it next time they see a new version
    announced. Half-working software, if useful, will intrigue people,
    whet their appetites for versions to come, and encourage them to
    join the development process.
   </para>

   <sect3>
    <title>When to release</title>

    <para>
     Making the decision to release your software for the first time
     is an incredibly important and incredibly stressful decision. But
     it needs to be done. My advice is to try and make something that
     is complete enough to be usable and incomplete enough to allow
     for flexibility and room for imagination by your future
     developers. It's not an easy decision. Ask for help on a local
     Linux User Group mailing list or from a group of developer
     friends.
    </para>

    <para>
     One tactic is to first do an <quote>alpha</quote> or
     <quote>beta</quote> release as described below in <xref
     linkend="alphabeta">. However, most of the guidelines described
     above still apply.
    </para>

     you've weighed the situation well several times, cross your
     fingers and take the plunge.</emphasis>
   </para>

    <para>
     After you've released for the first time, knowing when to release
     becomes less stressful, but just as difficult to gauge. I like
     the criteria offered by Robert Krawitz in his article, <ulink
     url="http://www.advogato.org/article/196.html"><quote>Free
     Software Project Management</quote></ulink> for maintaining a

    <para>
     If you've followed the guidelines described in this HOWTO up
     until this point, the mechanics of doing a release are going to
     be the easy part of releasing. If you have set up consistent
     distribution locations and the other infrastructure described in
     the preceding sections, releasing should be as simple as building
     the package, checking it once over, and uploading it into the
     appropriate place and then reflecting the release on your
     website.
    </para>

   <sect3 id="alphabeta">
    <title>Alpha, beta, and development releases</title>

    <para>
     When contemplating releases, it worth considering the fact that
     not every release needs to be a full numbered release. Software
     users are accustomed to pre-releases but you must be careful to
     label these releases accurately or they cause more problems then
     they are worth.

        out. Beta releases are great tool to whet the appetites of
        potential users by giving them a very realistic view of where

        development branch although there are other ways to use the
        term. So many in fact, that I feel the term has been
        cheapened. The popular window manager <ulink

        released <emphasis>nothing but</emphasis> development
        releases. Most often, the term is used to describe releases
        that are not even to alpha or beta stages though and if I were
        to release a pre-alpha version of a piece of software in order
        to keep interest in my project live, this is probably how I
        would have to label it.</para>

   <title>Announcing Your Project</title>

   <para>
    Well, you've done it. You've (at least for the purposes of this
    HOWTO) designed, built, and released your free software
    project. All that is left is for you to tell the world so they
    know to come and try it out and hopefully jump on board with
    development. If everything is in order as described above, this
    will be a quick and painless process. A quick announcement is all
    that it takes to put yourself on the free software communities
    radar screen.
   </para>

   <sect3>
    <title>Mailing lists and USENET</title>
    <para>
     Email is still the way that most people on the Internet get their
     information. Its a good idea to send a message announcing your
     program to any relevant mailing list you know of and any relevant
     USENET discussion group. Karl Fogel recommends that use you
     simple subject describing the fact that the message is an
     announcement, the name of the program, the version, and a
     half-line long description of its functionality. This way, any
     interested user or developer will be immediately attracted to
     your announcement. Fogel's example looks like:
    </para>

    <screen>Subject: ANN: aub 1.0, a program to assemble USENET binaries</screen>

    <para>
     The rest of the email should describe the programs functionality
     quickly and concisely in no more than two paragraphs and should
     provide links to the projects webpage and direct links to
     downloads for those that want to try it right away.
    </para>

    <para>
     You should repeat this announcement process consistently in the
     same locations for each subsequent release.

       job sketching the free software process and does an an amazing
       of job of making an argument for free software/open source
       development as making better software. The rest of the book has
       other articles, for the most part posted on his website, but
       it's nice thing to own in hard copy and something every free
       software/open source hacker should read.

      <para>
       In one of the better articles on the subject that I've read,
       Monty sums up some of the major points I touch on including:
       starting a project, testing, documenation, orgazing a team and
       leadership, and several other topics. While more opiniated that
       I try to be, I think its an important article that I found very
       helpful in writing this HOWTO and that I've tried to cite it in
       the places where I borrowed from it most. I have problems with
       much of the things written in the piece and I recommend you
       read <xref linkend="krawitz"> at the same time you read Monty's

   <para>
    I have spent a lot of time on advogato and I've gone through and
    provided links to the articles that I think are of particular
    interest to anyone reading this HOWTO. I think that looking
    through these is important. I promise that you'll learn a lot. You
    will learn that my idea of how a free software project should be
    run is not the <emphasis>only</emphasis> idea about how such a
    project can be done. I think that's great.

   <para>
    If nothing else, there is <emphasis>way</emphasis> more

    reference from this HOWTO. I have listed what I think are the most
    relavant articles here with short descriptions.

       This article made me happy because it challenged many of the

       author argues that Monty argues simply for the application of

       be extremely well thought out and I think its an essential read
       for any project manager.
