    <para>
     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 programming 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>
   For various reasons, this realease has been codenamed the
   <emphasis>homade yogurt</emphasis> release.
  </para>

  <para>
   New code names will appear as per industry standard
   guidelines to emphasize the state-of-the-art-ness of this
   document.
  </para>

  <para>
   Skimming through Freshmeat 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 recite it in your
   sleep and your project will probably fail. Then again, you can
   write a beautiful, relevent 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 bites and pieces of this HOWTO to Free
   Software developers on several occasions, I realized that 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>

  </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.

    the book are available under the GPL and constitute the best
    tutorial on CVS I have 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

    Also providing support and material, and inspiration for this

    carefully crafted arguments, to Lawrence Lessig for reminding me
    of the importance of Free Software and to every user and developer
    involved with the <ulink url="http://www.debian.org">Debian

    to practice Free Software advocacy and to make a difference, a

    Above all, I want to thank <emphasis>Richard Stallman</emphasis>

    missing? Don't hesitate to contact me and to write a chapter. I
    want this document to be as much a product of the Free Software

   <para>
    However, this HOWTO is still young and I have to yet to be
    contacted about a translation so English is all that is
    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, starting a project is most difficult
   part of successful free software development. Laying a firm
   foundation for your project 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 also involves a dilemna that you as a developer
   must try and deal with. No potential user for your program will be
   interested by a program that doesn't work. Simultaneously, the
   development process that you want to employ holds involvement of
   users as essential to the process of the development that will
   realize this working software.
  </para>

  <para>
   It is in these dangerous initial moments that anyone working to
   start a free software project must strike a balance. One of the
   most important ways that omeone trying to start a project can work
   towards this balance is by establishing a framework for the
   development process through some of the ways 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 a gap by doing something that no other free
    software process does or or does it in a way that is unique
    enought to necessitate a seperate project.
   </para>

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

    <para>
     In "The Cathedral and Bazaar," Raymond tells us that:
     <emphasis>Every good work of software starts by scratching a
     developers itch.</emphasis> Raymond 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 it is targetting a specific problem or itch you want to see
     scratched. <emphasis>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.</emphasis>
    </para>
   </sect3>

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

    <para>
     In evaluating your idea, you need to ask yourself 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 definately interested in seeing it
     implemented in code. But, because one hacker coding alone 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 <emphasis>no</emphasis>. If you want to
     write a set of scripts to sort <emphasis>your</emphasis> MP3
     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>
     MP3s, a free software project might fill a useful gap.
    </para>

    <para>
     Luckily, The Internet is a place so big and diverse that, chances
     are, there is someone, somewhere, who shares your interests and
     how feels the same itch. 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>
    </para>

     <sect4 id=evalwhere>
      <title>Finding Similar Projects</title>

     <para>
      There are places you can go on the web to try and answer this
      question. If you have experience with the free software
      community, you are probably already familiar with all of these
      sites. All of the resources listed bellow offer searching of
      their databases:

         else.</para>

     <title>Deciding to Proceed</title>
     <para>
      Once you have successfull 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 related to the goal of another
      project. Anyone starting a new project needs to ask themselves:
      <emphasis>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?</emphasis>
     </para>

     <para>
      If the answer to any of these questions is yes, try to contact
      the developer of the existing project 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 essential. It is easy
      to become fired up by and idea and be caught up in the momentum
      and excitement of a new project. It is often extremely difficult
      but it is important that any free software developer rememeber
      that the best interests of the 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.

<!-- Section2: licensing-->

  <sect2 id="licensing">
   <title>Licensing your Software</title>
   
   <para>
    On one level, the difference between a piece of free software and
    a piece of propriety software is the license. A license helps both
    you as the developer by protecting your legal rights to your
    software 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 flamewar as there are strong feelings that some free
     software licenses are better than other free software
     licenses. 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 allegiences in this argument are out in the open.
    </para>

    <para>
     In attempting to reach a middle ground, I recommend picking any
     license that conforms to the <ulink
     url="http://www.debian.org/social_contract">Debian Free Software
     Guidlines</ulink>. Examples of these licenses are the
     <acronym>GPL</acronym>, the <acronym>BSD</acronym>, and the
     Artistic License. Conforming to the definition of Free Software
     offered by Richard Stallman in <ulink
     url="http://www.gnu.org/philosophy/free-sw.html">The Free
     Software Definition</ulink>, any of these licenses will
     uphold,<quote> users' freedom to run, copy, distribute, study,
     change and improve the software.</quote> There are other licenses
     as well but sticking with a more common license will offer the
     advantage of immediate recognition and undestanding.
    </para>

    <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 majority of Linux software. Its an easy
     choice but I believe it is a good one. <emphasis>However, 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.</emphasis>
    </para>

    <para>
     The three major license can be found at the following locations:
    </para>

    <para>
     <itemizedlist>
      <listitem>

     </itemizedlist>
    </para>

    <para>

   <title>Choosing a Method of Version Numbering</title>
   <para>
    <emphasis>The most important thing about a system of 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. 
   </para>

   <para>
    <emphasis>The second most important thing about a system of

    versioning 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>
    Follow these two rules and you will not go wrong. Still there are
    several versioning system that are well known, useful, and that
    might be worth looking into before you release your first version.

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

      <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 taht 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 frusterated with the lack of
       development and progress that they complain. If you never
       release an odd minor version but only release even ones, nobody
       is hurt, and less people are confused.

   <title>Documentation</title>

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

   <para>
    There are lots of ways to document your project and lots of
    different people to document for. The idea of documentation the
    code itself to help facilitate development by a large community is
    vital but is outside the scope of this HOWTO. 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 method 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 its 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
    foo</quote> end up with a nicely formatted man page highlighting
    the basic use of their application. 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 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

    </para>

    <para>
     It is also possible to write man pages using DocBook SGML and
     convert them into man pages. Because manpages are so simple, 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 accessable documentation</title>

    <para>
     Most users will expect the most basic amount of documentation to
     be easily availabe from the command line. For few programs should
     then documentation extend for more than one screen (24 or 25
     lines) but it should cover the basic usage, a brief (one or two
     sentance) description of the program, a list of commands, all the
     major options, 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.

    <para>
     It has become a GNU convention to make this information
     accessable 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

         compiliation, and even basic use instructions that make up
         the bare minimum information needed to get the program up and
         running. A README is not your chance to be verbose but needs
         to be concise and effective. An ideal README is at least 30

         The INSTALL file should be much shorter than the INSTALL file
         and should quicly and concisely describe how to build and
         install the program. Usually an install simply instructs the
         user to run ./configure; make; make install and touches on
         any unusual options that may be necessary. More advanced
         users can usually avoid them but it's good practice to at
         least glance at the file 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 lines.

         file that, as its name would imply, logs or documents the
         changes to a program. The most simple way to do a changelog
         is to simply keep a file with teh 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 want or need to upgrade to a newer version or
         wait for a more signifigant upgrade.

     It's only a sort of an issue of documentation but a good website
     is quickly becoming an essential part of any free software
     project. Your website should provide access to documentation (in
     <acronym>HTML</acronym> if possible). It should also include a
     section for news and events around your program and a section
     that details the process of getting involved with development or

    <title>Package formats</title>
    <para>
     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 spotlit as a more effective compression medium. I now make
     all my releases available in both gzip'ed and bzip2'ed formats.
    </para>

    <para>
     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 specificed libraries and
     distributed in tar.gz format as well. <emphasis>Remember: While
     these binaries packages are nice, geting the source packaged and
     released should always be your priority. Other can and will do

    can only do so much. <emphasis>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.</emphasis>
   </para>

   <para>
    As your project progresses, you will notice people who are putting
    signfigant 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
    responsiblity to contact these people and to try and shift some of
    the power and responsiblity of your position as the project's
    maintainer onto them (if they want it). There are several easy
    weays you can do this:
   </para>

   <sect3>
    <title>How to delegate</title>
 
    <para>
     Like anything, its easier to see how others delegate than to do
     it yourself. In a sentance: <emphasis>Keep an eye out for other
     qualified developers who show an interest and sustained
     involvement with your project and try and shift responsibility
     towards them.</emphasis> The following ideas might be good places
     to start or good sources of inspiriation:
    </para>
 
    <sect4>
     <title>Allow a larger group of people write access to your CVS
     reponsitory and make real efforts towards rule by a
     committee</title>

     <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
      members and all have write access to the main source
      repository. Their process is detailed <ulink
      url="http://httpd.apache.org/ABOUT_APACHE.html">online.</ulink>
     </para>

     <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 <ulink
      url="http://www.debian.org/social_contract">social
      contract</ulink> and a <ulink
      url="http://www.debian.org/devel/constitution">constitution</ulink>. To
      facilitate this system, there are special teams (i.e. the
      install team, the Japanese language team) and a technical
      committee and a project lead. There is a project lead as well
      but the lead's main responsiblity is to, <quote>Appoint
      Delegates or delegate decisions to the Technical
      Committee.</quote>
     </para>

     <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 who lead who can do
      <emphasis>nothing</emphasis> but delegate can serve as a
      charicature of how a project can involve and empower a huge
      number of developers and grow to a huge size.

     <title>Publicly appoint someone as the release manager for a
       specific release.</title>

     <para>
      A relase manager is usually responsible for coordinating
      testing, encforcing a code freeze, being responsible for
      stability and quality control, packaging up the software, and
      placing it in the approrpriate places to be downloaded.
     </para>

     <para>
      This use of the release manager is a good way to give yourself a
      break and to shift the responsibility for accepting and
      rejecting patches to somenoe else. It is a good way of very
      clearly defining a chunk of work on the project as belonging to
      a certain person and its a great way of giving yourself a break.

     <title>Delegate control of an entire branch.</title>
     <para>
      If your project chooses to have branches (as described in <xref
      linkend="branches">), it might be a good idea to appoint someone
      else to be the the head of a branch. If you like focusing your
      energy on development releases and the implementation of new
      features, had total control over the stable releases to a
      well-suiteded developer.
     </para>

     <para>
      The author of linux, Linus Torvalds, came out and crowned Alan
      Cox as <quote>the man for stable kernels.</quote> All patches
      for stable kernels go to Alan and, if Linus were to be taken
      away from work on linux for any reason, Alan Cox would be more
      than suited to fill his role as the acknowledged heir to the
      linux maintainership.
