42 This HOWTO is designed for people with experience in programming
43 and some skills in managing a software project but who are new to
44 the world of free software. This document is meant to act as a
45 guide to the non-technical aspects of free software development
46 and was written to be a crash course in the people skills that
47 aren't taught to commercial coders but that can make or break a
48 free software project.
54 <!-- Section1: intro -->
57 <title>Introduction</title>
60 <primary>fswd!introduction</primary>
64 Skimming through freshmeat.net provides mountains of reasons for this
65 HOWTO's existence--the Internet is littered with excellently
66 written and useful programs that have faded away into the universe
67 of free software forgottenness. This dismal scene made me ask
72 This HOWTO tries to do a lot of thing (probably too many), but it
73 can't answer that question and won't attempt it. What this HOWTO
74 will attempt to do is give your Free Software project a fighting
75 chance--an edge. If you write a piece of crap that no one is
76 interested in, you can read this HOWTO until you can recite it in
77 your sleep and your project will probably fail. Then again, you can
78 write a beautiful, relevant piece of software and follow every
79 instruction in this HOWTO and your software may still not make
80 it. Sometimes life is like that. However, I'll go out a limb and
81 say that if you write a great, relevant pieces of software and
82 ignore the advise in this HOWTO, you'll probably fail <emphasis>
83 more often</emphasis>.
87 A lot of the information in this HOWTO is best called common
88 sense. Of course, as any debate on interfaces will prove, what is
89 common sense to some programmers proves totally unintuitive to
90 others. After explaining bits and pieces of this HOWTO to Free
91 Software developers on several occasions, I realized that writing
92 this HOWTO might provide a useful resource and a forum for
93 programmers to share ideas about what has and has not worked for
98 As anyone involved in any of what seems like an unending parade of
99 ridiculous intellectual property clashes will attest to, a little
100 bit of legalese proves important.

250 In this version I have the pleasure of acknowledging:
254 <emphasis>Karl Fogel</emphasis>, the author of <emphasis>Open
255 Source Development with CVS</emphasis> published by the Coriolis
256 Open Press. Large parts of his book are available <ulink
257 url="http://cvsbook.red-bean.com">on the web</ulink>. 225 pages of
258 the book are available under the GPL and constitute the best
259 tutorial on CVS I've ever seen. The rest of the book covers, "the
260 challenges and philosophical issues inherent in running an Open
261 Source project using CVS." The book does a good job of covering
262 some of the subjects brought up in this HOWTO and much
263 more. <ulink url="http://cvsbook.red-bean.com">The book's
264 website</ulink> has information on ordering the book and provides
265 several translations of the chapters on CVS. If you are seriously
266 interested in running a Free Software project, you want this
267 book. I tried to mention Fogel in sections of this HOWTO where I
268 knew I was borrowing directly from his ideas. If I missed any, I'm
269 sorry. I'll try and have those fixed in future versions.
273 Karl Fogel can be reached at <email>kfogel (at) red-bean (dot)
278 Also providing support material, and inspiration for this HOWTO is
279 Eric S. Raymond for his prolific, consistent, and carefully
280 crafted arguments and Lawrence Lessig for reminding me of the
281 importance of Free Software. Additionaly, I want to thank every
282 user and developer involved with the <ulink
283 url="http://www.debian.org">Debian Project</ulink>. The project
284 has provided me with a home, a place to practice free software
285 advocacy, a place to make a difference, a place to learn from
286 those how have been involved with the movement much longer than I,
287 and proof of a free software project that definitely, definitely
292 Above all, I want to thank <emphasis>Richard Stallman</emphasis>
293 for his work at the Free Software Foundation and for never giving
294 up. Stallman provides and articulates the philosophical basis that
295 attracts me to free software and that drives me towards writing a
296 document to make sure it succeeds. RMS can always be emailed at

327 I know that not everyone speaks English. Translations are nice and
328 I'd love for this HOWTO to gain the kind of international reach
329 afforded by translated versions.
333 However, this HOWTO is still young and I have to yet to be
334 contacted about a translation so English is all that is currently
335 available. If you would like to help with or do a translation, you
336 will gain my utmost respect and admiration and you'll get to be

345 <!-- Section1: starting -->
347 <sect1 id="starting">
348 <title>Starting a Project</title>
351 <primary>fswd!starting</primary>
354 With very little argument, the beginning is the most difficult part
355 of successful free software development. Laying a firm foundation
356 will determine whether your project flourishes or withers away and
357 dies. It is also the subject that is of most immediate interest to
358 anyone reading this document as a tutorial.
362 Starting a project involves a dilemma that you as a developer must
363 try and deal with: no potential user for your program is interested
364 in a program that doesn't work while the development process that
365 you want to employ holds involvement of users as imperative.
369 It is in these dangerous initial moments that anyone working to
370 start a free software project must try and strike a balance along
371 these lines. One of the most important ways that someone trying to
372 start a project can work towards this balance is by establishing a
373 solid framework for the development process through some of the
374 suggestions mentioned in this section.
378 <!-- Section2: chooseproject-->
380 <sect2 id="chooseproject">
381 <title>Choosing a Project</title>
384 If you are reading this document, there's a good chance you
385 already have an idea for a project in mind. Chances are also
386 pretty good that it fills a percieved gap by doing something that
387 no other free software project does or by doing something in a way
388 that is unique enough to necessitate a brand new piece of
392 <sect3 id=identifyidea>
393 <title>Identify and articulate your idea</title>
395 Eric S. Raymond writes about how free software projects start in
396 his essay, <quote>The Cathedral and the Bazaar,</quote> which
397 comes as required reading for any free software developer. It is
399 url="http://www.tuxedo.org/~esr/writings/cathedral-bazaar/">online
404 In <quote>The Cathedral and the Bazaar,</quote> Raymond tells us
405 that: <quote>every good work of software starts by scratching
406 a developers itch.</quote> Raymond's now widely accepted
407 hypothesis is that new free software programs are written, first
408 and foremost, to solve a specific problem facing the developer.
412 If you have an idea for a program in mind, chances are good that
413 it targets a specific problem or <quote>itch</quote> you want to
414 see scratched. <emphasis>This idea is the project.</emphasis>
415 Articulate it clearly. Write it out. Describe the problem you
416 will attack in detail. The success of your project in tackling a
417 particular problem will be tied to your ability to identify that
418 problem clearly early on. Find out exactly what it is that you
419 want your project to do.
423 Monty Manley articulates the importance of this initial step in
424 an essay, <quote><ulink
425 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
426 Projects the Open Source Way.</ulink></quote> As the next section
427 will show, there is <emphasis>a lot</emphasis> of work that needs
428 to be done before software is even ready to be coded. Manley
429 says, <quote>Beginning an OSS project properly means that a
430 developer must, first and foremost, avoid writing code too
435 <sect3 id=evalulateidea>
436 <title>Evaluate your idea</title>
439 In evaluating your idea, you need to first ask yourself a few
440 questions. This should happen before you move any further
441 through this HOWTO. Ask yourself: <emphasis>Is the free software
442 development model really is the right one for your
447 Obviously, since the program scratches your itch, you are
448 definitely interested in seeing it implemented in code. But,
449 because one hacker coding in solitude fails to qualify as a free
450 software development effort, you need to ask yourself a second
451 question: <emphasis>Is anybody else interested?</emphasis>
455 Sometimes the answer is a simple <quote>no.</quote> If you want
456 to write a set of scripts to sort <emphasis>your</emphasis>
457 <acronym>MP3</acronym> collection on <emphasis>your</emphasis>
458 machine, <emphasis>maybe</emphasis> the free software development
459 model is not the best one to choose. However, if you want to
460 write a set of scripts to sort <emphasis>anyone's</emphasis>
461 <acronym>MP3</acronym>s, a free software project might fill a
466 Luckily, The Internet is a place so big and so diverse that,
467 chances are, there is someone, somewhere, who shares your
468 interests and how feels the same <quote>itch.</quote> It is the
469 fact that there are so many people with so many similar needs and
470 desires that introduces the third major question: <emphasis>Has
471 somebody already had your idea or a reasonably similar
476 <title>Finding Similar Projects</title>
479 There are places you can go on the web to try and answer the
480 question above. If you have experience with the free software
481 community, you are probably already familiar with many of these
482 sites. All of the resources listed bellow offer searching of
489 <term>freshmeat.net</term>
491 <para><ulink url="http://freshmeat.net">freshmeat.net</ulink>
492 describes itself as, <quote>the Web's largest index of Linux
493 and Open Source software</quote> and its reputation along
494 these lines is totally unparalleled and unquestioned. If you
495 can't find it on freshmeat, its doubtful that you (or anyone
496 else) will find it at all.</para>
501 <term>Slashdot</term>
503 <para><ulink url="http://slashdot.org">Slashdot</ulink>
504 provides <quote>News for Nerds: Stuff that Matters,</quote>
505 which usually includes discussion of free software, open
506 source, technology, and geek culture new and events. It is
507 not unusual for an particularly sexy development effort to be
508 announced here so it definitely worth checking.</para>
513 <term>SourceForge</term>
515 <para><ulink url="http://sourceforge.net">SourceForge</ulink>
516 houses and facilitates a growing number of open source and
517 free software projects. It is also quickly becoming a nexus
518 and an necessary stop for free software
519 developers. SourceForge's <ulink
520 url="http://sourceforge.net/softwaremap/trove_list.php">software
521 map</ulink> and <ulink url="http://sourceforge.net/new/"> new

523 embarking on a new free software project. SourceForge also

535 <para><ulink url="http://www.google.com">Google</ulink> and
536 <ulink url="http://www.google.com/linux"> Google's Linux
537 Search</ulink>, provide powerful web searches that may reveal
538 people working on similar projects. It is not a catalog of
539 software or news like freshmeat or Slashdot, but it is worth
540 checking to make sure you aren't pouring your effort into a
541 redundant project.</para>
550 <title>Deciding to Proceed</title>
552 Once you have successfully charted the terrain and have an idea
553 about what kinds of similar free software projects exist, every
554 developer needs to decide whether to proceed with their own
555 project. It is rare that a new project seeks to accomplish a
556 goal that is not at all similar or related to the goal of
557 another project. Anyone starting a new project needs to ask
558 themselves: <quote>Will the new project be duplicating work done
559 by another project? Will the new project be competing for
560 developers with an existing project? Can the goals of the new
561 project be accomplished by adding functionality to an existing
566 If the answer to any of these questions is <quote>yes,</quote>
567 try to contact the developer of the existing project(s) in
568 question and see if he or she might be willing to collaborate
573 For many developers this may be the single most difficult aspect
574 of free software development but it is an essential one. It is
575 easy to become fired up by an idea and be caught up in the
576 momentum and excitement of a new project. It is often extremely
577 difficult to do but, it is important that any free software
578 developer remember that the best interests of the free software
579 community and the quickest way to accomplish your own project's
580 goals and the goals of similar projects can often be
581 accomplished by <emphasis>not</emphasis> starting a new
589 <!-- Section2: naming-->
592 <title>Naming your project</title>
595 While there are plenty of projects that fail with descriptive
596 names and plenty that succeed without them, I think naming your
597 project is worth giving a bit of thought. Leslie Orchard tackles
598 this issue in an <ulink
599 url="http://www.advogato.org/article/67.html">Advogato
600 article</ulink>. His article is short and definately worth looking
605 The synopsis is that Orchard recommends you pick a name where,
606 after hearing the name, many users or developers will both:
612 <para>Know what the project does.</para>
615 <para>Remember it tomorrow.</para>
621 Humorously, Orchard's project, <quote>Iajitsu,</quote> does
622 neither. It is probably unrelated that development has effectively
623 frozen since the article was written.
627 He makes a good point though. There are companies whose only job
628 is to make names for pieces of software. They make
629 <emphasis>ridiculous</emphasis> amount of money doing it and are
630 supposedly worth it. While you probably can't aford a company like
631 this, you can afford to learn from their existance and think a
632 little bit about the name you are giving your project because it
633 <emphasis>does</emphasis> matter.
637 If there is a name you really want but it doesn't fit Orchard's
638 criteria, you can still go ahead. I thought <quote>gnubile</quote>
639 was one of the best I'd heard for a free software project ever and
640 I still talk about it long after I've stopped using the
641 program. However, if you can flexible on the subject, listen to
642 Orchard's advice. It might help you.
646 <!-- Section2: licensing-->
648 <sect2 id="licensing">
649 <title>Licensing your Software</title>
652 On one (somewhat simplistic) level, the difference between a piece
653 of free software and a piece of propriety software is the
654 license. A license helps you as the developer by protecting your
655 legal rights to have your software distributed under your terms
656 and helps demonstrate to those who wish to help you or your
657 project that they are encouraged to join.
660 <sect3 id="chooselicense">
661 <title>Choosing a license</title>
664 Any discussion of licenses is also sure to generate at least a
665 small flame war as there are strong feelings that some free
666 software licenses are better than others. This discussion also
667 brings up the question of <quote>Open Source Software</quote> and
668 the debate over the terms <quote>Open Source Software</quote> and
669 <quote>Free Software</quote>. However, because I've written the
670 Free Software Development HOWTO and not the Open Source
671 Development HOWTO, my own allegiances in this argument are in the
676 In attempting to reach a middle ground through diplomacy without
677 sacrificing my own philosophy, I will recommend picking any
678 license that conforms to the <ulink
679 url="http://www.debian.org/social_contract">Debian Free Software
680 Guidelines</ulink>. Originally compiled by the Debian project
681 under Bruce Perens, the <acronym>DFSG</acronym> forms the first
682 version of the <ulink
683 url="http://www.opensource.org/docs/definition_plain.html">Open
684 Source Definition.</ulink> Examples of free licenses given by the
685 <acronym>DFSG</acronym> are the <acronym>GPL</acronym>, the
686 <acronym>BSD</acronym>, and the Artistic License.
690 Conforming to the definition of free software offered by Richard
692 url="http://www.gnu.org/philosophy/free-sw.html"><quote>The Free
693 Software Definition</quote></ulink>, any of these licenses will
694 uphold, <quote>users' freedom to run, copy, distribute, study,
695 change and improve the software.</quote> There are plenty of
696 other licenses that also conform to the <acronym>DFSG</acronym>
697 but sticking with a more well-known license will offer the advantage
698 of immediate recognition and understanding.
702 In attempting a more in-depth analysis, I agree with Karl Fogel's
703 description of licenses as falling into two groups: those that
704 are the <acronym>GPL</acronym> and those that are not the
705 <acronym>GPL</acronym>.
709 Personally, I license all my software under the
710 <acronym>GPL</acronym>. Created and protected by the Free
711 Software Foundation and the GNU Project, the
712 <acronym>GPL</acronym> is the license for the Linux kernel,
713 GNOME, Emacs, and the vast majority of GNU/Linux software. It's
714 the obvious choice but I believe it is a good one. Any BSD
715 fanatic will urge you to remember that there is a viral aspect to
716 the <acronym>GPL</acronym> that prevents the mixture of
717 <acronym>GPL</acronym>'ed code with non-<acronym>GPL</acronym>'ed
718 code. To many people (myself included), this is a benefit, but to
719 some, it is a major drawback.
723 The three major licenses can be found at the following locations:
729 <para><ulink url="http://www.gnu.org/copyleft/gpl.html">The GNU
730 General Public License</ulink></para>
733 <para><ulink url="http://www.debian.org/misc/bsd.license">The
734 BSD License</ulink></para>
738 url="http://language.perl.com/misc/Artistic.html">The Artistic
739 License</ulink></para>
745 <emphasis>In any case, please read through any license before
746 your release your software under it. As the primary developer,
747 you can't afford any license surprises.</emphasis>
751 <sect3 id="licensechoose">
752 <title>The mechanics of licensing</title>
755 The text of the <acronym>GPL</acronym> offers <ulink
756 url="http://www.gnu.org/copyleft/gpl.html#SEC4">a good
757 description</ulink> of mechanics of applying a license to a piece
758 of software. My quick checklist for applying a license includes:
765 <para>If at all possible, attach and distribute a full copy of
766 the license with the source and binary by including a separate
771 <para>At the top of each source file in your program, attach a
772 notice of copyright and include information on where the full
773 license can be found. The <acronym>GPL</acronym> recommends
774 that each file begin with:</para>
777 <emphasis>one line to give the program's name and an idea of what it does.</emphasis>

858 <title>Choosing a Method of Version Numbering</title>
861 <emphasis>The most important thing about a system of version
862 numbering is that there is one.</emphasis> It may seem pedantic to
863 emphasize this point but you'd be surprised at the number of
864 scripts and small programs that pop up without any version number
869 <emphasis>The second most important thing about a system of
870 numbering is that the numbers always go up.</emphasis> Automatic
871 version tracking systems and people's sense of order in the
872 universe will fall apart if version numbers don't rise. It doesn't
873 <emphasis>really</emphasis> matter if 2.1 is a big jump and
874 2.0.005 is a small jump but it does matter that 2.1 is more recent
879 Follow these two simple rules and you will not go (too)
880 wrong. Beyond this, the most common technique seems to be the
881 <quote>major level,</quote> <quote>minor level,</quote>
882 <quote>patch level</quote> version numbering scheme. Whether you
883 are familiar with the name or not, you interact with it all the
884 time. The first number is the major number and it signifies major
885 changes or rewrites. The second number is the minor number and it
886 represents added or tweaked functionality on top of a largely
887 coherant structure. The third number is the patch number and it
888 usually will only refer to releases fixing bugs.
892 The widespread use of this scheme is why I know the nature and
893 relative degree in the differences between a 2.4.12 release of the
894 Linux kernel and a 2.4.11, 2.2.12, and 1.2.12 without knowning
895 anything about any of the releases.
899 You can bend or break these rules, and people do. But beware, if
900 you choose to, someone will get annoyed, assume you don't know,
901 and try and educate you, probably not nicely. I always follow this
902 method and I implore you to do so as well.
906 There are several version numbering systems that are well known,
907 useful, and that might be worth looking into before you release
913 <term>Linux kernel version numbering:</term>
915 <para>The Linux kernel uses a versioning system where any odd
916 minor version number refers to an development or testing release
917 and any even minor version number refers to a stable
918 version. Think about it for a second. Under this system, 2.1 and
919 2.3 kernels were and always will be development or testing
920 kernels and 2.0, 2.2. and 2.4 kernels are all production code
921 with a higher degree of stability and more testing.
925 Whether you plan on having a split development model (as
926 described in <xref linkend="branches">) or only one version
927 released at a time, my experience with several free software
928 projects and with the Debian project has taught me that use of
929 Linux's version numbering system is worth taking into
930 consideration. In Debian, <emphasis>all</emphasis> minor
931 versions are stable distributions (2.0, 2.1, etc). However,
932 many people assume that 2.1 is an unstable or development
933 version and continue to use an older version until they get so
934 frustrated with the lack of development progress that they
935 complain and figure the system out. If you never release an odd
936 minor version but only release even ones, nobody is hurt, and
937 less people are confused. It's an idea worth taking into
944 <term>Wine version numbering:</term>
946 <para>Because of the unusual nature of wine's development where
947 the not-emulator is constantly improving but not working towards
948 any immediately achievable goal, wine is released every three
949 weeks. Wine does this by labeling their releases in <quote>Year
950 Month Day</quote> format where each release might be labeled
951 <quote>wine-XXXXXXXX</quote> where the version from January 04,
952 2000 would be <quote>wine-20000104</quote>. For certain
953 projects, <quote>Year Month Day</quote> format can make a lot of
960 <term>Mozilla milestones:</term>
962 <para>When one considers Netscape 6 and vendor versions, the
963 mozilla's project development structure is one of the most
964 complex free software models available. The project's version
965 numbering has reflected the unique situation in which it is
970 Mozilla's version numbering structure has historically been
971 made up of milestones. From the beginning of the mozilla
972 project, the goals of the project in the order and degree to
973 which they were to be achieved were charted out on a series of
974 <ulink url="http://www.mozilla.org/roadmap.html">road
975 maps</ulink>. Major points and achievements along these
976 road-maps were marked as milestones. Therefore, although
977 mozilla was built and distributed nightly as <quote>nightly
978 builds,</quote> on a day when the goals of a milestone on the
979 road-map had been reached, that particular build was marked as
980 a <quote>milestone release.</quote>
984 While I haven't seen this method employed in any other projects
985 to date, I like the idea and think that it might have value in
986 any testing or development branch of a large application under
995 <!-- Section2: documentation-->
997 <sect2 id="documentation">
998 <title>Documentation</title>
1001 A huge number of otherwise fantastic free software applications
1002 have withered and died because their author was the only person
1003 who knew how to use them fully. Even if your program is written
1004 primarily for a techno-savvy group of users, documentation is
1005 helpful and even necessary for the survival of your project. You
1006 will learn later in <xref linkend="releasing"> that you should
1007 always release something that is usable. <emphasis>A piece of
1008 software without documentation is not usable.</emphasis>
1012 There are lots of different people you should document for and
1013 there are lots of ways to document your project. <emphasis>The
1014 importance of documentation in source code to help facilitate
1015 development by a large community is vital</emphasis> but it falls
1016 outside the scope of this HOWTO. This being the case, this section
1017 deals with useful tactics for user-directed documentation.
1021 A combination of tradition and necessity has resulted in a
1022 semi-regular system of documentation in most free software
1023 projects that is worth following. Both users and developers expect
1024 to be able to get documentation in several ways and it's essential
1025 that you provide the information they are seeking in a form they
1026 can read if your project is ever going to get off the
1027 ground. People have come to expect:
1031 <title>Man pages</title>
1033 <para>Your users will want to be able to type <quote>man
1034 yourprojectname</quote> end up with a nicely formatted man page
1035 highlighting the basic use of your application. Make sure that
1036 before you release your program, you've planned for this.
1040 Man pages are not difficult to write. There is excellent
1041 documentation on the man page writing process available through
1042 the <quote>The Linux Man-Page-HOWTO</quote> which is available
1043 through the Linux Documentation project <acronym>(LDP)</acronym>
1044 and is written by Jens Schweikhardt. It is available <ulink
1045 url="http://www.schweikhardt.net/man_page_howto.html">from
1046 Schweikhardt's site</ulink> or <ulink
1047 url="http://www.linuxdoc.org/HOWTO/mini/Man-Page.html">from the
1048 <acronym>LDP</acronym></ulink>.
1052 It is also possible to write man pages using DocBook
1053 SGML. Because man pages are so simple and the DocBook method
1054 relatively new, I have not been able to follow this up but would
1055 love help from anyone who can give me more information on how
1056 exactly how this is done.
1061 <title>Command line accessible documentation</title>
1064 Most users will expect some basic amount of documentation to be
1065 easily available from the command line. For few programs should
1066 this type of documentation extend for more than one screen (24 or
1067 25 lines) but it should cover the basic usage, a brief (one or
1068 two sentence) description of the program, a list of the commands
1069 with explanations, as well as all the major options (also with
1070 explanations), plus a pointer to more in-depth documentation for
1071 those who need it. The command line documentation for Debian's
1072 apt-get serves as an excellent example and a useful model:
1076 apt 0.3.19 for i386 compiled on May 12 2000 21:17:27
1077 Usage: apt-get [options] command
1078 apt-get [options] install pkg1 [pkg2 ...]
1080 apt-get is a simple command line interface for downloading and
1081 installing packages. The most frequently used commands are update
1085 update - Retrieve new lists of packages
1086 upgrade - Perform an upgrade
1087 install - Install new packages (pkg is libc6 not libc6.deb)
1088 remove - Remove packages
1089 source - Download source archives
1090 dist-upgrade - Distribution upgrade, see apt-get(8)
1091 dselect-upgrade - Follow dselect selections
1092 clean - Erase downloaded archive files
1093 autoclean - Erase old downloaded archive files
1094 check - Verify that there are no broken dependencies
1098 -q Loggable output - no progress indicator
1099 -qq No output except for errors
1100 -d Download only - do NOT install or unpack archives
1101 -s No-act. Perform ordering simulation
1102 -y Assume Yes to all queries and do not prompt
1103 -f Attempt to continue if the integrity check fails
1104 -m Attempt to continue if archives are unlocatable
1105 -u Show a list of upgraded packages as well
1106 -b Build the source package after fetching it
1107 -c=? Read this configuration file
1108 -o=? Set an arbitary configuration option, eg -o dir::cache=/tmp
1109 See the apt-get(8), sources.list(5) and apt.conf(5) manual
1110 pages for more information and options.
1114 It has become a GNU convention to make this type of information
1115 accessible with the <quote>-h</quote> and the
1116 <quote>--help</quote> options. Most GNU/Linux users will expect
1117 to be able to retrieve basic documentation these ways so if you
1118 choose to use different methods, be prepared for the flames and
1119 fallout that may result.
1124 <title>Files users will expect</title>
1126 In addition to man pages and command-line help, there are certain
1127 files where people will look for documentation, especially in any
1128 package containing source code. In a source distribution, most of
1129 these files can be stored in a the root directory of the source
1130 distribution or in a subdirectory of the root called
1131 <quote>doc</quote> or <quote>Documentation.</quote> Common files
1132 in these places include:
1138 <term>README or Readme</term>
1141 <para>A document containing all the basic installation,
1142 compilation, and even basic use instructions that make up the
1143 bare minimum information needed to get the program up and
1144 running. A README is not your chance to be verbose but should
1145 be concise and effective. An ideal README is at least 30 lines
1146 long and more no more than 250.</para>
1151 <term>INSTALL or Install</term>
1154 <para>The INSTALL file should be much shorter than the README
1155 file and should quickly and concisely describe how to build
1156 and install the program. Usually an INSTALL file simply
1157 instructs the user to run <quote>./configure; make; make
1158 install</quote> and touches on any unusual options or actions
1159 that may be necessary. For most relatively standard install
1160 procedures and for most programs, INSTALL files are as short
1161 as possible are rarely over 100 lines.</para>
1166 <term>CHANGELOG, Changelog, ChangeLog, or changelog</term>
1169 <para>A CHANGELOG is a simple file that every well-managed
1170 free software project should include. A CHANGELOG is simple
1171 the file that, as its name implies, logs or documents the
1172 changes you make to your program. The most simple way to
1173 maintain a CHANGELOG is to simply keep a file with the source
1174 code for your program and add a section to the top of the
1175 CHANGELOG with each release describing what has been, changed,
1176 fixed, or added to the program. It's a good idea to post the
1177 CHANGELOG onto the website as well because it can help people
1178 decide whether they want or need to upgrade to a newer version
1179 or wait for a more significant improvement.</para>
1187 <para>A NEWS file and a ChangeLog are similar. Unlike a
1188 CHANGELOG, a NEWS file is not typically updated with new
1189 versions. Whenever new features are added, the developer
1190 responisble will make a note in the NEWS file. NEWS files
1191 should not have to be changed before a release (they should be
1192 kept up to date all along) but it's usually a good idea to
1193 check first anyway because often developers just forget to
1194 keep them as current as they should.</para>
1199 <term><acronym>FAQ</acronym></term>
1202 <para>For those of you that don't already know,
1203 <acronym>FAQ</acronym> stands for Frequently Asked Questions
1204 and a FAQ is a collection of exactly that. FAQs are not
1205 difficult to make. Simply make a policy that if you are asked
1206 a question or see a question on a mailing list two or more
1207 times, add the question (and its answer) to your FAQ. FAQs are
1208 more optional than the files listed above but they can save
1209 your time, increase usability, and decrease headaches on all
1219 <title>Website</title>
1221 It's only indirectly an issue of documentation but a good website
1222 is quickly becoming an essential part of any free software
1223 project. Your website should provide access to your documentation
1224 (in <acronym>HTML</acronym> if possible). It should also include
1225 a section for news and events around your program and a section
1226 that details the process of getting involved with development or
1227 testing and make an open invitation. It should also supply links
1228 to any mailing lists, similar websites, and provide a direct link
1229 to all the available ways of downloading your software.
1234 <title>Other documentation hints</title>
1237 All your documentation should be in plaintext, or, in cases where
1238 it is on your website primarily, in HTML. Everyone can cat a
1239 file, everyone has a pager, (almost) everyone can render
1240 HTML. <emphasis>You are welcome to distribute information in PDF,
1241 PostScript, RTF, or any number of other widely used formats but
1242 this information must also be available in plaintext or HTML or
1243 people will be very angry at you.</emphasis>
1247 It doesn't hurt to distribute any documentation for your program
1248 from your website (FAQs etc) with your program. Don't hesitate
1249 throw any of this in the program's tarball. If people don't need
1250 it, they will delete it. I can repeat it over and over:
1251 <emphasis>Too much documentation is not a sin.</emphasis>
1256 <!-- Section2: presentation -->
1258 <sect2 id="presentation">
1259 <title>Other Presentation Issues</title>
1261 Many of the remaining issues surrounding the creation of a new
1262 free software program fall under what most people describe as
1263 common sense issues. Its often said that software engineering is
1264 90 percent common sense combined with 10 percent specialized
1265 knowledge. Still, they are worth noting briefly in hopes that they
1266 may remind a developer of something they may have forgotten.
1270 <title>Package formats</title>
1272 Package formats may differ depending on the system you are
1273 developing for. For windows based software, Zip archives (.zip)
1274 usually serve as the package format of choice. If you are
1275 developing for GNU/Linux, *BSD, or any UN*X, make sure that your
1276 source code is always available in tar'ed and gzip'ed format
1277 (.tar.gz). UNIX compress (.Z) has gone out of style and
1278 usefulness and faster computers have brought bzip2 (.bz2) into
1279 the spot-light as a more effective compression medium. I now make
1280 all my releases available in both gzip'ed and bzip2'ed tarballs.
1284 Binary packages should always be distribution specific. If you
1285 can build binary packages against a current version of a major
1286 distribution, you will only make your users happy. Try to foster
1287 relationships with users or developers of large distributiosn to
1288 develop a system for the consistent creation of binary
1289 packages. It's often a good idea to provide RedHat
1290 <acronym>RPM</acronym>'s (.rpm), Debian deb's (.deb) and source
1291 <acronym>RPM</acronym>'s <acronym>SRPM</acronym>'s if
1292 possible. Remember: <emphasis>While these binaries packages are
1293 nice, getting the source packaged and released should always be
1294 your priority. Your users or fellow developers can and will do
1295 the the binary packages for you.</emphasis>
1300 <title>Version control systems</title>
1303 A version control system can make a lot of these problems of
1304 packaging (and a lot of other problems mentioned in this HOWTO)
1305 less problematic. If you are using *NIX, CVS is your best bet. I
1306 recommend Karl Fogel's book on the subject (and the <ulink
1307 url="http://cvsbook.red-bean.com/">posted HTML version</ulink>)
1312 CVS or not, you should probably invest some time into learning
1313 about a version control system because it provides an automated
1314 way of solving many of the problems described by this HOWTO. I
1315 am not aware of any free version control systems for Windows or
1316 MacOS but I know that CVS clients exist for both
1317 platforms. Websites like <ulink
1318 url="http://sourceforge.net">SourceForge</ulink> do a great job
1319 as well with a nice, easy-to-use web interface to CVS.
1323 I'd love to devote more space in this HOWTO to CVS because I love
1324 it (I even use CVS to keep versions straight on this HOWTO!) but
1325 I think it falls outside the scope of this document and should
1326 (already has) its own HOWTO.
1332 <title>Useful tidbits and presentation hints</title>
1335 Other useful hints include:
1343 <emphasis>Make sure that your program can always be found in a
1344 single location.</emphasis> Often this means that you have a
1345 single directory accessible via <acronym>FTP</acronym> or the
1346 web where the newest version can be quickly recognized. One
1347 effective technique is a provide a symlink called
1348 <quote>yourprojectname-latest</quote> that is always pointing
1349 to the most recent released or development version of your
1350 free software application. Keep in mind that this location
1351 will recieve many requests for downloads around releases so
1352 make sure that the server you choose has adequate bandwidth.
1358 <emphasis>Make sure that there is a consistent email address
1359 for bug reports.</emphasis> It's usually a good idea to make
1360 this something that is NOT your primary email address like
1361 yourprojectname@host or yourprojectname-bugs@host. This way,
1362 if you ever decide to hand over maintainership or if your
1363 email address changes, you simply need to change where this
1364 email address forwards. It also will allow for more than one
1365 person to deal with the influx of mail that is created if your
1366 project becomes as huge as you hope it will.

1381 <title>Maintaining a Project: Interacting with Developers</title>
1383 <primary>fswd!developers</primary>
1387 Once you have gotten your project started, you have overcome the
1388 most difficult hurdles in the development process of your
1389 program. Laying a firm foundation is essential, but the development
1390 process itself is equally important and provides just as many
1391 opportunities for failure. In the next two sections, I will
1392 describe running a project by discussing how to maintain a
1393 development effort through interactions with developers and with
1398 In releasing your program, your program becomes free software. This
1399 transition is more than just a larger user base. By releasing your
1400 program as free software, <emphasis>your</emphasis> software
1401 becomes the <emphasis>free software community's</emphasis>
1402 software. The direction of your software's development will be
1403 reshaped, redirected, and fully determined by your users and, to a
1404 larger extent, by other developers in the community.
1408 The major difference between free software development and
1409 propriety software development is the developer base. As the leader
1410 of a free software project, you need to attract and keep developers
1411 in a way that leaders of proprietary software projects simply don't
1412 have to worry about. <emphasis>As the person leading development of
1413 a free software project, you must harness the work of fellow
1414 developers by making responsible decisions and by responsibly
1415 choosing not to make decisions. You have to direct developers
1416 without being overbearing or bossy. You need to strive to earn
1417 respect and never forget to give it out.</emphasis>
1420 <!-- Section2: delegation -->
1422 <sect2 id="delegation">
1423 <title>Delegating Work</title>
1426 By now, you've hypothetically followed me through the early
1427 programming of a piece of software, the creation of a website and
1428 system of documentation, and we've gone ahead and (as will be
1429 discussed in <xref linkend="releasing">) released it to the rest
1430 of the world. Times passes, and if things go well, people become
1431 interested and want to help. The patches begin flowing in.
1435 <emphasis>Like the parent of any child who grows up, it's now time
1436 to wince, smile and do most difficult thing in any parents
1437 life: It's time to let go.</emphasis>
1441 Delegation is the political way of describing this process of
1442 <quote>letting go.</quote> It is the process of handing some of
1443 the responsibility and power over your project to other
1444 responsible and involved developers. It is difficult for anyone
1445 who has invested a large deal of time and energy into a project
1446 but it essential for the growth of any free software project. One
1447 person can only do so much. A free software project is nothing
1448 without the involvement of <emphasis>a group</emphasis> of
1449 developers. A group of developers can only be maintained through
1450 respectful and responsible leadership and delegation.
1454 As your project progresses, you will notice people who are putting
1455 significant amounts of time and effort into your project. These
1456 will be the people submitting the most patches, posting most on
1457 the mailing lists, and engaging in long email discussions. It is
1458 your responsibility to contact these people and to try and shift
1459 some of the power and responsibility of your position as the
1460 project's maintainer onto them (if they want it). There are
1461 several easy ways you can do this:
1465 In a bit of a disclaimer, delegation need not mean rule by
1466 comittee. In many cases it does and this has been proven to
1467 work. In other cases this has created problems. <ulink
1468 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
1469 Projects the Open Source Way</ulink> argues that <quote>OSS
1470 projects do best when one person is the clear leader of a team and
1471 makes the big decisions (design changes, release dates, and so
1472 on).</quote> I think this often true but would urge developers to
1473 consider the ideas that the project leader need not be the
1474 project's founder and that these important powers need not all rest
1475 with one person but that a release manager may be different than a
1476 lead developer. These situations are tricky politically so
1477 be careful and make sure it's necessary before you go around
1482 <title>How to delegate</title>
1485 You may find that other developers seem even more experienced or
1486 knowledgeable than you. Your job as a maintainer does not mean
1487 you have to be the best or the brightest. It means you
1488 are responsible for showing good judgment and for
1489 recognizing which solutions are maintainable and which are not.
1492 Like anything, its easier to watch others delegate than to do it
1493 yourself. In a sentence: <emphasis>Keep an eye out for other
1494 qualified developers who show an interest and sustained
1495 involvement with your project and try and shift responsibility
1496 towards them.</emphasis> The following ideas might be good places
1497 to start or good sources of inspiration:
1501 <title>Allow a larger group of people to have write access to your CVS
1502 repository and make real efforts towards rule by a
1506 <ulink url="http://httpd.apache.org/">Apache</ulink> is an
1507 example of a project that is run by small group of developers
1508 who vote on major technical issues and the admission of new
1509 members and all have write access to the main source
1510 repository. Their process is detailed <ulink
1511 url="http://httpd.apache.org/ABOUT_APACHE.html">online.</ulink>
1515 The <ulink url="http://www.debian.org/"> Debian Project</ulink>

1517 more than 700 developers have full responsibility for
1518 aspects of the project. All these developers can upload into
1519 the main FTP server, and vote on major issues. Direction for
1520 the project is determined by the project's <ulink
1521 url="http://www.debian.org/social_contract">social
1522 contract</ulink> and a <ulink
1523 url="http://www.debian.org/devel/constitution">constitution</ulink>. To
1524 facilitate this system, there are special teams (i.e. the
1525 install team, the Japanese language team) as well as a technical
1526 committee and a project leader. The leader's main responsibility
1527 is to, <quote>appoint delegates or delegate decisions to the
1528 Technical Committee.</quote>
1532 While both of these projects operate on a scale that your
1533 project will not (at least initially), their example is
1534 helpful. Debian's idea of a project leader who can do
1535 <emphasis>nothing</emphasis> but delegate serves as a
1536 caricature of how a project can involve and empower a huge
1537 number of developers and grow to a huge size.
1542 <sect4 id="releasemanager">
1543 <title>Publicly appoint someone as the release manager for a
1544 specific release</title>
1547 A release manager is usually responsible for coordinating
1548 testing, enforcing a code freeze, being responsible for
1549 stability and quality control, packaging up the software, and
1550 placing it in the appropriate places to be downloaded.
1554 This use of the release manager is a good way to give yourself a
1555 break and to shift the responsibility for accepting and
1556 rejecting patches onto someone else. It is a good way of very
1557 clearly defining a chunk of work on the project as belonging to
1558 a certain person and its a great way of giving yourself room to

1564 <title>Delegate control of an entire branch</title>
1566 If your project chooses to have branches (as described in <xref
1567 linkend="branches">), it might be a good idea to appoint someone
1568 else to be the the head of a branch. If you like focusing your
1569 energy on development releases and the implementation of new
1570 features, hand total control over the stable releases to a
1571 well-suited developer.

1577 for stable kernels go to Alan and, if Linus were to be taken
1578 away from work on Linux for any reason, Alan Cox would be more
1579 than suited to fill his role as the acknowledged heir to the
1580 Linux maintainership.

1589 <title>Accepting and Rejecting Patches</title>
1591 This HOWTO has already touched on the fact that as the maintainer
1592 of a free software project, one of your primary and most important
1593 responsibilities will be accepting and rejecting patches submitted
1594 to you by other developers.
1598 <title>Technical judgment</title>
1601 In <emphasis>Open Source Development with CVS</emphasis>, Karl
1602 Fogel makes a convincing argument that the most important things
1603 to keep in mind when rejecting or accepting patches are:
1610 <para>A firm knowledge of the scope of your program (that's the
1611 <quote>idea</quote> I talked about in <xref linkend="chooseproject">);</para>
1615 <para>The ability to recognize, facilitate, and direct
1616 <quote>evolution</quote> of your program so that the program
1617 can grow and change and incorporate functionality that was
1618 originally unforeseen;</para>
1622 <para>The necessity to avoid digressions that might expand the
1623 scope of the program too much and result and push the project
1624 towards an early death under its own weight and
1625 unwieldiness.</para>
1632 These are the criteria that you as a project maintainer should
1633 take into account each time you receive a patch.
1637 Fogel elaborates on this and states the <quote>the
1638 questions to ask yourself when considering whether to implement
1639 (or approve) a change are:</quote>
1646 <para>Will it benefit a significant percentage of the program's
1647 user community?</para>
1651 <para>Does it fit within the program's domain or within a
1652 natural, intuitive extension of that domain?</para>
1659 The answers to these questions are never straightforward and its
1660 very possible (and even likely) that the person who submitted the
1661 patch may feel differently about the answer to these questions
1662 than you do. However, if you feel that that the answer to either
1663 of those questions is <quote>no,</quote> it is your responsibility
1664 to reject the change. If you fail to do this, the project will
1665 become unwieldy and unmaintainable and many ultimately fail.
1670 <title>Rejecting patches</title>
1673 Rejecting patches is probably the most difficult and sensitive
1674 job that the maintainer of any free software project has to
1675 face. But sometimes it has to be done. I mentioned earlier (in
1676 <xref linkend="developers"> and in <xref linkend="delegation">)
1677 that you need to try and balance your responsibility and power to
1678 make what you think are the best technical decisions with the
1679 fact that you will lose support from other developers if you seem
1680 like you are on a power trip or being overly bossy or possessive
1681 of the community's project. I recommend that you keep these three
1682 major concepts in mind when rejecting patches (or other changes):
1686 <title>Bring it to the community</title>
1688 One of the best ways of justifying a decision to reject a patch
1689 and working to not seem like you keep an iron grip on your
1690 project is by not making the decision alone at all. It might
1691 make sense to turn over larger proposed changes or more
1692 difficult decisions to a development mailing list where they can
1693 be discussed and debated. There will be some patches (bug fixes,
1694 etc.) which will definitely be accepted and some that you feel
1695 are so offbase that they do not even merit further
1696 discussion. It is those that fall into the grey area between
1697 these two groups that might merit a quick forward to a mailing
1702 I recommend this process wholeheartedly. As the project
1703 maintainer you are worried about making the best decision for
1704 the project, for the project's users and developers, and for
1705 yourself as a responsible project leader. Turning things over to
1706 an email list will demonstrate your own responsibility and
1707 responsive leadership as it tests and serves the interests of
1708 your software's community.
1713 <title>Technical issues are not always good justification</title>
1715 Especially towards the beginning of your project's life, you
1716 will find that many changes are difficult to implement,
1717 introduce new bugs, or have other technical problems. Try to see
1718 past these. Especially with added functionality, good ideas do
1719 not always come from good programmers. Technical merit is a
1720 valid reason to postpone an application of a patch but it is not
1721 always a good reason to reject a change outright. Even small
1722 changes are worth the effort of working with the developer
1723 submitting the patch to iron out bugs and incorporate the change
1724 if you think it seems like a good addition to your project. The
1725 effort on your part will work to make your project a community
1726 project and it will pull a new or less experienced developer
1727 into your project and even teach them something that might help
1728 them in making their next patch.
1733 <title>Common courtesy</title>
1735 It should go without saying but, <emphasis>above all and in all
1736 cases, just be nice.</emphasis> If someone has an idea and cares
1737 about it enough to write some code and submit a patch, they
1738 care, they are motivated, and they are already involved. Your
1739 goal as the maintainer is make sure they submit again. They may
1740 have thrown you a dud this time but next time may be the idea or
1741 feature that revolutionizes your project.
1745 It is your responsibility to first justify your choice to not
1746 incorporate their change clearly and concisely. Then thank
1747 them. Let them know that you a appreciate their help and feel
1748 horrible that you can't incorporate their change. Let them know
1749 that you look forward to their staying involved and you hope
1750 that the next patch or idea meshes better with your project
1751 because you appreciate their work and want to see it in your
1752 application. If you have ever had a patch rejected after putting
1753 a large deal of time, thought, and energy into it, you remember
1754 how it feels and it feels bad. Keep this in mind when you have
1755 to let someone down. It's never easy but you need to do
1756 everything you can to make it as not-unpleasant as possible.
1762 <!-- Section2: branches -->
1764 <sect2 id="branches">
1765 <title>Stable and Development Branches</title>
1768 The idea of stable and development branches has already been
1769 described briefly in <xref linkend="chooseversioning"> and in
1770 <xref linkend="delegatebranch">. These allusions attest to some of
1771 the ways that multiple branches can affect your software. Branches
1772 can let you avoid (to some extent) some of the problems around
1773 rejecting patches (as described in <xref linkend="patching">) by
1774 allowing you to temporarily compromise the stability of your
1775 project without affecting those users who need that stability.
1779 The most common way of branching your project is to have one
1780 branch that is stable and one that is for development. This is the
1781 model followed by the Linux kernel that is described in <xref
1782 linkend="chooseversioning">. In this model, there is
1783 <emphasis>always</emphasis> one branch that is stable and always
1784 one that is in development. Before any new release, the
1785 development branch goes into a <quote>feature freeze</quote> as
1786 described in <xref linkend="freezing"> where major changes and
1787 added features are rejected or put on hold under the development
1788 kernel is released as the new stable branch and major development
1789 resumes on the development branch. Bug fixes and small changes
1790 that are unlikely to have any large negative repercussions are
1791 incorporated into the stable branch as well as the development
1796 Linux's model provides an extreme example. On many projects, there is no
1797 need to have two versions constantly available. It may make sense to
1798 have two versions only near a release. The Debian project has
1799 historically made both a stable and an unstable distribution
1800 available but has expanded to this to include: stable, unstable,
1801 testing, experimental, and (around release time) a frozen
1802 distribution that only incorporates bug fixes during the
1803 transition from unstable to stable. There are few projects whose
1804 size would necessitate a system like Debian's but this use of
1805 branches helps demonstrate how they can be used to balance
1806 consistent and effective development with the need to make regular
1807 and usable releases.
1811 In trying to set up a development tree for yourself, there are
1812 several things that might be useful to keep in mind:
1819 <term>Minimize the number of branches</term>
1821 <para>Debian may be able to make good use of four or five
1822 branches but it contains gigabytes of software in over 5000
1823 packages compiled for 5-6 different architectures. For you,
1824 two is probably a good ceiling. Too many branches will confuse
1825 your users (I can't count how many times I had to describe
1826 Debian's system when it only had 2 and sometimes 3 branches!),
1827 potential developers and even yourself. Branches can help but
1828 they come at a cost so use them very sparingly.</para>
1833 <term>Make sure that all your different branches are explained</term>
1835 <para>As I mentioned in the preceding paragraph, different
1836 branches <emphasis>will</emphasis> confuse your users. Do
1837 everything you can to avoid this by clearly explaining the
1838 different branches in a prominent page on your website and in a
1839 README file in the <acronym>FTP</acronym> or
1840 web directory.</para>
1843 I might also recommend against a mistake that I think Debian
1844 has made. The terms <quote>unstable,</quote>
1845 <quote>testing,</quote> and <quote>experimental</quote> are
1846 vague and difficult to rank in order of stability (or
1847 instability as the case may be). Try explaining to someone
1848 that <quote>stable</quote> actually means <quote>ultra
1849 stable</quote> and that <quote>unstable</quote> doesn't
1850 actually include any unstable software but is really stable
1851 software that is untested as a distribution.
1855 If you are going to use branches, especially early on, keep in
1856 mind that people are conditioned to understand the terms
1857 <quote>stable</quote> and <quote>development</quote> and you
1858 probably can't go wrong with this simple and common division of
1865 <term>Make sure all your branches are always available</term>
1867 <para>Like a lot of this document, this should probably should
1868 go without saying but experience has taught me that it's not
1869 always obvious to people. It's a good idea to physically split
1870 up different branches into different directories or directory
1871 trees on your <acronym>FTP</acronym> or web site. Linux
1872 accomplishes this by having kernels in a v2.2 and a v2.3
1873 subdirectory where it is immediately obvious (after you know
1874 their version numbering scheme) which directory is for the most
1875 recent stable and the current development releases. Debian
1876 accomplishes this by naming all their distribution with names
1877 (i.e. woody, potato, etc.) and then changing symlinks named
1878 <quote>stable,</quote> <quote>unstable</quote> and
1879 <quote>frozen</quote> to point to which ever distribution (by
1880 name) is in whatever stage. Both methods work and there are
1881 others. In any case, it is important that different branches
1882 are always available, are accessible from consistent locations,
1883 and that different branches are clearly distinguished from each
1884 other so your users know exactly what they want and where to

1897 <title>Other Development issues</title>
1899 There are more issues surrounding interaction with developers in a
1900 free software project that I can not touch on in great detail in a
1901 HOWTO of this size and scope. Please don't hesitate to contact me if you see
1902 any major omissions.
1906 Other smaller issues that are worth mentioning are:
1909 <sect3 id="freezing">
1910 <title>Freezing</title>
1912 For those projects that choose to adopt a split development model
1913 (<xref linkend="branches">), freezing is a concept that is worth
1914 becoming familiar with.
1918 Freezes come in two major forms. A <quote>feature freeze</quote>
1919 is a period when no significant functionality is added to a
1920 program. It is a period where established functionality (even
1921 skeletons of barely working functionality) can be improved and
1922 perfected. It is a period where bugs are fixed. This type of
1923 freeze is usually applied some period (a month or two) before a
1924 release. It is easy to push a release back as you wait for
1925 <quote>one more feature</quote> and a freeze helps to avoid this
1926 situation by drawing the much needed line in the sand. It gives
1927 developers room they need to get a program ready for release.
1931 The second type of freeze is a <quote>code freeze</quote> which
1932 is much more like a released piece of software. Once a piece of
1933 software has entered a <quote>code freeze,</quote> all changes to
1934 the code are discouraged and only changes that fix known bugs
1935 are permitted. This type of freeze usually follows a
1936 <quote>feature freeze</quote> and directly precedes a
1937 release. Most released software is in what could be interpreted
1938 as a sort of high level <quote>code freeze.</quote>
1942 Even if you never choose to appoint a release manager (<xref
1943 linkend="releasemanager">), you will have an easier time
1944 justifying the rejection or postponement of patches (<xref
1945 linkend="patching">) before a release with a publicly stated
1951 <title>Forking</title>
1953 Forks are like the most extreme version of a branch. A fork is
1954 when a group of developers takes code from a free software
1955 project and actually starts a brand new free software
1956 project with it. The most famous example of a fork was between Emacs and
1957 XEmacs. Both emacsen are based on an identical code-base
1958 but for technical, political, and philosophical reasons,
1959 development was split into two projects which now compete with
1964 The short version of the fork section is, <emphasis>don't do
1965 them.</emphasis> Forks force developers to choose one project to
1966 work with, cause nasty political divisions, and redundancy of
1967 work. Luckily, usually the threat of the fork is enough to scare
1968 the maintainer or maintainers of a project into changing the way
1969 they run their project.
1973 In his chapter on <quote>The Open Source Process,</quote> Karl
1974 Fogel describes how to do a fork if you absolutely must. If you
1975 have determined that is absolutely necessary and that the
1976 differences between you and the people threatening to fork are
1977 absolutely unresolvable, I recommend Fogel's book as a good place

1987 <title>Maintaining a Project: Interacting with Users</title>
1989 <primary>fswd!users</primary>
1993 If you've worked your way up to here, congratulations, you are
1994 nearing the end of this document. This final section describes some
1995 of the situations in which you, in your capacity as project
1996 maintainer, will be interacting with users. It gives some
1997 suggestions on how these situations might be handled effectively.
2001 Interacting with users is difficult. In our discussion of
2002 interaction with developers, the underlying assumption is that in a
2003 free software project, a project maintainer must constantly strive to
2004 attract and keep developers who can easily leave at any time.
2008 Users in the free software community are different than developers
2009 and are also different than users in the world of proprietary
2010 software and they should be treated differently than either
2011 group. Some ways in which the groups differ significantly follow:
2018 <para>The lines between users and developers are blurred in ways
2019 that is totally foreign to any proprietary development
2020 model. Your users are often your developers and vice
2025 <para>In the free software world, you are often your users' only
2026 choice. Because there is such an emphasis on not replicating the
2027 work of others in the free software community and because the
2028 element of competition present in the propriety software model is
2029 absent (or at least in an extremely different form) in the free
2030 software development model, you will probably be the only project
2031 that does what you do (or at least the only one that does what
2032 you do in the way that you do it). This means your responsiveness
2033 to your users is even more important than in the proprietary
2034 software world.</para>
2038 <para>In an almost paradoxical situation, free software projects
2039 have less immediate or dire consequences for ignoring their users
2040 altogether. It is also often easier to do. Because you don't
2041 usually need to compete with another product, chances are good
2042 that you will not be scrambling to gain the features of your
2043 competitor's newest program. This means that your development
2044 process will have to be directed either internally, by a
2045 commitment to your users, or through both.</para>
2051 Trying to tackle this unique situation can only be done
2052 indirectly. Developers and maintainers need to listen to users and
2053 to try and be as responsive as possible. A solid knowledge of the
2054 situation recounted above is any free software developer's best tool
2055 for shifting his development or leadership style to fit the unique
2056 process of free software development. This chapters will try and
2057 introduce some of the more difficult or important points in any
2058 projects interactions with users and give some hints on how to
2062 <!-- Section2: testing -->
2064 <sect2 id="testing">
2065 <title>Testing and Testers</title>
2068 In addition to your users being your developers, they are also
2069 (and perhaps more commonly) your testers. Before I get flamed, I
2070 should rephrase my sentence: <emphasis>some of your
2071 users</emphasis> (those who explicityly volunteer) are your
2076 It is important that this distinction be made early on because not
2077 all of your users want to be testers. Many users want to use
2078 stable software and don't care if they don't have the newest,
2079 greatest software with the latest, greatest features. These users
2080 except a stable, tested piece of software without major or obvious
2081 bugs and will be angry if they find themselves testing. This is
2082 yet another way in which a split development model (as mentioned
2083 in <xref linkend="branches">) might come in handy.

2121 questions above is probably <quote>failure</quote> which is
2122 often the only answer. Now make sure that it happens
2123 nicely. Make sure that when it crashes, there is some indication
2124 of why it crashed or failed so that the user or developer
2125 understands whats going on.</para>
2131 <term>Standards conformance</term>
2134 <para>If possible, make sure your programs conforms to
2135 standards. If it's interactive, don't be too creative with
2136 interfaces. If it is non-interactive, make sure it communicates
2137 over appropriate and established channels with other programs
2138 and with the rest of the system.</para>
2145 <title>Automated testing</title>
2147 For many programs, many common mistakes can be caught by
2148 automated means. Automated tests tend to be pretty good at
2149 catching errors that you've run into several times before or
2150 the things you just forget. They are not very good at finding
2151 errors, even major ones, that are totally unforeseen.
2155 CVS comes with a bourne shell script called sanity.sh that is
2156 worth looking at. Debian uses a program called lintian that
2157 checks Debian packages for all of the most common errors. While
2158 use of these scripts may not be helpful, there is a host of other
2159 sanity checking software on the net that may be applicable (feel
2160 free to email me any recommendations). None of these will create
2161 a bug-free release but they will avoid at least some major
2162 oversights. Finally, if your programs become a long term
2163 endeavor, you will find that there are certain errors that you
2164 tend to make over and over. Start a collection of scripts that
2165 check for these errors to help keep them out of future releases.
2170 <title>Testing by testers</title>
2172 For any program that depends on user interactivity, many bugs
2173 will only be uncovered through testing by users actually clicking
2174 the keys and pressing the mouse buttons. For this you need
2175 testers and as many as possible.
2179 The most difficult part of testing is finding testers. It's
2180 usually a good tactic to post a message to a relevant mailing
2181 list or news group announcing a specific proposed release date
2182 and outlining the functionality of your program. If you put some
2183 time into the announcement, you are sure to get a few responses.
2187 The second most difficult part of testing is
2188 <emphasis>keeping</emphasis> your testers and keeping them
2189 actively involved in the testing process. Fortunately, there are
2190 some tried and true tactics that can applied towards this end:
2197 <term>Make things simple for your testers</term>
2199 <para>Your testers are doing you a favor so make it as easy as
2200 possible for them. This means that you should be careful to
2201 package your software in a way that is easy to find, unpack,
2202 install, and uninstall. This also means you should explain
2203 what you are looking for to each tester and make the means for
2204 reporting bugs simple and well established. The key is to
2205 provide as much structure as possible to make your testers'
2206 jobs easy and to maintain as much flexibility as possible for
2207 those that want to do things a little differently.</para>
2212 <term>Be responsive to your testers</term>
2214 <para>When your testers submit bugs, respond to them and
2215 respond quickly. Even if you are only responding to tell them
2216 that the bug has already been fixed, quick and consistent
2217 responses make them feel like their work is heard, important,
2218 and appreciated.</para>
2223 <term>Thank your testers</term>
2225 <para>Thank them personally each time they send you
2226 patch. Thank them publicly in the documentation and the about
2227 section of your program. You appreciate your testers and your
2228 program would not be possible without their help. Make sure
2229 they know it. Publicly, pat them on the back to make sure the rest of
2230 the world knows it too. It will be appreciated more than you

2243 <sect2 id="support">
2244 <title>Setting up Support Infrastructure</title>
2247 While testing is important, the large part of your interactions
2248 and responsibility to your users falls under the category of
2249 support. The best way to make sure your users are adequately
2250 supported in using your program is to set up a good infrastructure
2251 for this purpose so that your developers and users help each other
2252 and less of the burden falls on you. This way, people will also
2253 get quicker and better responses to their questions. This
2254 infrastructure comes in several major forms:
2258 <title>Documentation</title>
2260 It should not come as any surprise that the key element to any
2261 support infrastructure is good documentation. This topic was
2262 large covered in <xref linkend="documentation"> and will not be
2268 <title>Mailing lists</title>
2270 Aside from documentation, effective mailing lists will be your
2271 greatest tool in providing user support. Running a mailing list
2272 well is more complicated than installing mailing list software
2277 <title>Separate lists</title>
2280 A good idea is too separate your user and development mailing
2281 lists (perhaps into project-user@host and project-devel@host)
2282 and enforce the division. If people post a development question
2283 onto -user, politely ask them to repost it onto -devel and vise
2284 versa. Subscribe yourself to both groups and encourage all
2285 primarily developers to do the same.
2289 This system provides so that no one person is stuck doing all of
2290 the support work and works so that users learn more about the
2291 program, they can help newer users with their questions.
2296 <title>Choose mailing list software well</title>
2298 Please don't make the selection of mailing list software
2299 impulsively. Please consider easy accessibility by users without
2300 a lot of technical experience so you want to be as easy as
2301 possible. Web accessibility to an archive of the list is also
2306 The two biggest free software mailing list programs are <ulink
2307 url="http://www.greatcircle.com/majordomo/">majordomo</ulink>
2308 and <ulink url="http://www.list.org/">GNU Mailman</ulink>. A
2309 long time advocate of majordomo, I would now recommend any
2310 project choose GNU Mailman. It fulfills the criteria listed
2311 above and makes it easier. It provides a good mailing
2312 list program for a free software project maintainer as opposed
2313 to a good mailing list application for a mailing list
2318 There are other things you want to take into consideration in
2319 setting up your list. If it is possible to gate your mailing
2320 lists to USENET and provide it in digest form as well as
2321 making them accessible on the web, you will please some users
2322 and work to make the support infrastructure slightly more
2329 <title>Other support ideas</title>
2332 A mailing list and accessible documentation are far from all you
2333 can do to set up good user support infrastructure. Be
2334 creative. If you stumble across something that works well, email me
2335 and I'll include it here.
2339 <title>Make your self accessible</title>
2341 You can not list too few methods to reach you. If you hang out
2342 in an <acronym>IRC</acronym> channel, don't hesitate to list it
2343 in your projects documentation. List email and snailmail
2344 addresses, and ways to reach you via <acronym>ICQ</acronym>,
2345 <acronym>AIM</acronym>, or Jabber if they apply.
2350 <title>Bug management software</title>
2352 For many large software projects, use of bug management software
2353 is essential to keep track of which bugs have been fixed, which
2354 bugs have not been fixed, and which bugs are being fixed by
2355 which people. Debian uses the <ulink
2356 url="http://bugs.debian.org">Debian Bug Tracking System</ulink>
2357 (<acronym>BTS</acronym>) although it may not be best choice for
2358 every project (it seems to currently be buckling under its own
2359 weight) As well as a damn good web browser, the mozilla project
2360 has spawned a sub-project resulting in a bug tracking system
2362 url="http://www.mozilla.org/projects/bugzilla/">bugzilla</ulink>
2363 which has become extremely possible and which I like a lot.
2367 These systems (and others like them) can be unwieldy so
2368 developers should be careful to not spend more time on the bug
2369 tracking system than on the bugs or the projects themselves. If
2370 a project continues to grow, use of a bug tracking system can
2371 provide an easy standard avenue for users and testers to report
2372 bugs and for developers and maintainers to fix them and track
2373 them in an orderly fashion.
2379 <!-- Section2: releasing -->
2381 <sect2 id="releasing">
2382 <title>Releasing Your Program</title>
2385 As mentioned earlier in the HOWTO, the first rule of releasing is,
2386 <emphasis>release something useful.</emphasis> Non-working or
2387 not-useful software will not attract anyone to your
2388 project. People will be turned off of your project and will be likely
2389 to simply gloss over it next time they see a new version
2390 announced. Half-working software, if useful, will intrigue people,
2391 whet their appetites for versions to come, and encourage them to
2392 join the development process.
2396 <title>When to release</title>
2399 Making the decision to release your software for the first time
2400 is an incredibly important and incredibly stressful decision. But
2401 it needs to done. My advice is to try and make something that
2402 is complete enough to be usable and incomplete enough to allow
2403 for flexibility and room for imagination by your future
2404 developers. It's not an easy decision. Ask for help on a local
2405 Linux User Group mailing list or from a group of developer
2410 One tactic is to first do an <quote>alpha</quote> or
2411 <quote>beta</quote> release as described below in <xref
2412 linkend="alphabeta">. However, most of the guidelines described
2417 <emphasis>When you feel in your gut that it is time and you feel
2418 you've weighed the situation well several times, cross your
2419 fingers and take the plunge.</emphasis>
2423 After you've released for the first time, knowing when to release
2424 becomes less stressful, but just as difficult to gauge. I like
2425 the criteria offered by Robert Krawitz in his article, <ulink
2426 url="http://www.advogato.org/article/196.html"><quote>Free
2427 Software Project Management</quote></ulink> for maintaining a
2428 good release cycle. He recommends that you ask yourself,
2429 <quote>does this release...</quote>
2435 <para>Contain sufficient new functionality or bug fixes to be
2436 worth the effort.</para>
2440 <para>Be spaced sufficiently far apart to allow the user time
2441 to work with the latest release.</para>
2445 <para>Be sufficiently functional so that the user can get work
2446 done (quality).</para>
2452 If the answer is yes to all of these questions, its probably time
2453 for a release. If in doubt, remember that asking for advice can't
2459 <title>How to release</title>
2462 If you've followed the guidelines described in this HOWTO up
2463 until this point, the mechanics of doing a release are going to
2464 be the easy part of releasing. If you have set up consistent
2465 distribution locations and the other infrastructure described in
2466 the preceding sections, releasing should be as simple as building
2467 the package, checking it once over, and uploading it into the
2468 appropriate place and then making your website reflect the
2473 <sect3 id="alphabeta">
2474 <title>Alpha, beta, and development releases</title>
2477 When contemplating releases, it worth considering the fact that
2478 not every release needs to be a full numbered release. Software
2479 users are accustomed to pre-releases but you must be careful to
2480 label these releases accurately or they will cause more problems then
2485 The observation is often made that many free software developers
2486 seem to be confused about the release cycle. <quote><ulink
2487 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
2488 Projects the Open Source Way</ulink></quote> suggests that you memorize
2489 the phrase, <quote>Alpha is not Beta. Beta is not Release</quote>
2490 and I'd agree that tis is a probably a good idea.
2497 <term>alpha releases</term>
2499 <para>Alpha software is feature-complete but sometimes only
2500 partially functional.</para>
2502 <para>Alpha releases are expected to be unstable, perhaps a
2503 little unsafe, but definitely usable. They
2504 <emphasis>can</emphasis> have known bugs and kinks that have
2505 yet to be worked out. Before releasing an alpha, be sure to
2506 keep in mind that <emphasis>alpha releases are still
2507 releases</emphasis> and people are not going to be expecting a
2508 nightly build from the CVS source. An alpha should work and
2509 have minimal testing and bug fixing already finished.</para>
2514 <term>beta releases</term>
2516 <para>Beta software is feature-complete and functional, but is
2517 in the testing cycle and still has a few bugs left to be
2520 <para>Beta releases are general expected to be usable and
2521 slightly unstable, although definitely <emphasis>not
2522 unsafe.</emphasis> Beta releases usually preclude a full
2523 release by under a month. They can contain small known bugs
2524 but no major ones. All major functionality should be fully
2525 implemented although the exact mechanics can still be worked
2526 out. Beta releases are great tool to whet the appetites of
2527 potential users by giving them a very realistic view of where
2528 your project is going to be in the very near future and can
2529 help keep interest by giving people
2530 <emphasis>something.</emphasis></para>
2535 <term>development releases</term>
2537 <para><quote>Development release</quote> is much a more vague
2538 term than <quote>alpha</quote> or <quote>beta</quote>. I
2539 usually choose to reserve the term for discussion of a
2540 development branch although there are other ways to use the
2541 term. So many in fact, that I feel the term has been
2542 cheapened. The popular window manager <ulink
2543 url="http://www.enlightenment.org">Enlightenment</ulink> has
2544 released <emphasis>nothing but</emphasis> development
2545 releases. Most often, the term is used to describe releases
2546 that are not even alpha or beta and if I were to release a
2547 pre-alpha version of a piece of software in order to keep
2548 interest in my project alive, this is probably how I would
2549 have to label it.</para>
2559 <!-- Section2: announcing -->
2561 <sect2 id="announcing">
2562 <title>Announcing Your Project</title>
2565 Well, you've done it. You've (at least for the purposes of this
2566 HOWTO) designed, built, and released your free software
2567 project. All that is left is for you to tell the world so they
2568 know to come and try it out and hopefully jump on board with
2569 development. If everything is in order as described above, this
2570 will be a quick and painless process. A quick announcement is all
2571 that it takes to put yourself on the free software community's
2576 <title>Mailing lists and USENET</title>
2578 Email is still the way that most people on the Internet get their
2579 information. Its a good idea to send a message announcing your
2580 program to any relevant mailing list you know of and any relevant
2581 USENET discussion group. Karl Fogel recommends that use you
2582 simple subject describing the fact that the message is an
2583 announcement, the name of the program, the version, and a
2584 half-line long description of its functionality. This way, any
2585 interested user or developer will be immediately attracted to
2586 your announcement. Fogel's example looks like:
2589 <screen>Subject: ANN: aub 1.0, a program to assemble USENET binaries</screen>
2592 The rest of the email should describe the programs functionality
2593 quickly and concisely in no more than two paragraphs and should
2594 provide links to the projects webpage and direct links to
2595 downloads for those that want to try it right away.
2599 You should repeat this announcement process consistently in the
2600 same locations for each subsequent release.

2607 Mentioned earlier in <xref linkend="evalwhere">, in today's free
2608 software community, announcements of your project on freshmeat
2609 are almost more important than announcements on mailing lists.

2617 database. In addition to a large website, freshmeat provides a
2618 daily newsletter that highlights all the days releases and
2619 reaches a huge audience (I personally skim it every night for any
2620 interesting new releases).

2823 I have spent a huge amount of time on advogato and I've gone
