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

237 Anyone who gave me an idea for a better name and everyone who
238 assured me that a <citetitle>Project Management HOWTO</citetitle>
239 didn't necessary sound corporate.
243 Josh Crawford, Andy King, and Jaime Davila who all read through
244 this in entirety and gave me feedback that has helped me make
245 changes and improvements to this document. I can't thank you guys
246 enough for your help. An extra <quote>Thank You</quote> goes to

254 of his book are available <ulink
255 url="http://cvsbook.red-bean.com">on the web</ulink>. 225 pages of
256 the book are available under the GPL and constitute the best
257 tutorial on CVS I've ever seen. The rest of the book covers,
258 <quote>the challenges and philosophical issues inherent in running
259 an Open Source project using CVS.</quote> The book does a good job
260 of covering some of the subjects brought up in this HOWTO and much
261 more. <ulink url="http://cvsbook.red-bean.com">The book's
262 website</ulink> has information on ordering the book and provides
263 several translations of the chapters on CVS. If you are seriously
264 interested in running a Free Software project, you want this
265 book. I tried to mention Fogel in sections of this HOWTO where I
266 knew I was borrowing directly from his ideas. If I missed any, I'm
267 sorry. I'll try and have those fixed in future versions.

276 Also providing support material, and inspiration for this HOWTO is
277 Eric S. Raymond for his prolific, consistent, and carefully
278 crafted arguments and Lawrence Lessig for reminding me of the
279 importance of Free Software. Additionaly, I want to thank every
280 user and developer involved with the <ulink
281 url="http://www.debian.org">Debian Project</ulink>. The project
282 has provided me with a home, a place to practice free software
283 advocacy, a place to make a difference, a place to learn from
284 those who have been involved with the movement much longer than I,
285 and proof of a free software project that definitely, definitely
290 Above all, I want to thank <emphasis>Richard Stallman</emphasis>
291 for his work at the Free Software Foundation and for never giving
292 up. Stallman provides and articulates the philosophical basis that
293 attracts me to free software and that drives me towards writing a

327 afforded by translated versions.
331 However, this HOWTO is still young and I have to yet to be
332 contacted about a translation so English is all that is currently
333 available. If you would like to help with or do a translation, you

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

519 map</ulink> and <ulink url="http://sourceforge.net/new/"> new

521 embarking on a new free software project. SourceForge also

533 <para><ulink url="http://www.google.com">Google</ulink> and
534 <ulink url="http://www.google.com/linux"> Google's Linux
535 Search</ulink>, provides powerful web searches that may reveal
536 people working on similar projects. It is not a catalog of
537 software or news like freshmeat or Slashdot, but it is worth
538 checking to make sure you aren't pouring your effort into a
539 redundant project.</para>
548 <title>Deciding to Proceed</title>
550 Once you have successfully charted the terrain and have an idea
551 about what kinds of similar free software projects exist, every
552 developer needs to decide whether to proceed with their own
553 project. It is rare that a new project seeks to accomplish a
554 goal that is not at all similar or related to the goal of
555 another project. Anyone starting a new project needs to ask
556 themselves: <quote>Will the new project be duplicating work done
557 by another project? Will the new project be competing for
558 developers with an existing project? Can the goals of the new
559 project be accomplished by adding functionality to an existing
564 If the answer to any of these questions is <quote>yes,</quote>
565 try to contact the developer of the existing project(s) in
566 question and see if he or she might be willing to collaborate
571 For many developers this may be the single most difficult aspect
572 of free software project managment, but it is an essential one. It is
573 easy to become fired up by an idea and get caught up in the
574 momentum and excitement of a new project. It is often extremely
575 difficult to do, but it is important that any free software
576 developer remembers that the best interests of the free software
577 community and the quickest way to accomplish your own project's
578 goals and the goals of similar projects can often be
579 accomplished by <emphasis>not</emphasis> starting a new
587 <!-- Section2: naming-->
590 <title>Naming your project</title>
593 While there are plenty of projects that fail with descriptive
594 names and plenty that succeed without them, I think naming your
595 project is worth giving a bit of thought. Leslie Orchard tackles
596 this issue in an <ulink
597 url="http://www.advogato.org/article/67.html">Advogato
598 article</ulink>. His article is short and definately worth looking
603 The synopsis is that Orchard recommends you pick a name where,
604 after hearing the name, many users or developers will both:
610 <para>Know what the project does.</para>
613 <para>Remember it tomorrow.</para>
619 Humorously, Orchard's project, <quote>Iajitsu,</quote> does
620 neither. It is probably unrelated that development has effectively
621 frozen since the article was written.
625 He makes a good point though. There are companies whose only job
626 is to make names for pieces of software. They make
627 <emphasis>ridiculous</emphasis> amount of money doing it and are
628 supposedly worth it. While you probably can't aford a company like
629 this, you can afford to learn from their existance and think a
630 little bit about the name you are giving your project because it
631 <emphasis>does</emphasis> matter.
635 If there is a name you really want but it doesn't fit Orchard's
636 criteria, you can still go ahead. I thought <quote>gnubile</quote>
637 was one of the best I'd heard for a free software project ever and
638 I still talk about it long after I've stopped using the
639 program. However, if you can be flexible on the subject, listen to
640 Orchard's advice. It might help you.
644 <!-- Section2: licensing-->
646 <sect2 id="licensing">
647 <title>Licensing your Software</title>
650 On one (somewhat simplistic) level, the difference between a piece
651 of free software and a piece of propriety software is the
652 license. A license helps you as the developer by protecting your
653 legal rights to have your software distributed under your terms
654 and helps demonstrate to those who wish to help you or your
655 project that they are encouraged to join.
658 <sect3 id="chooselicense">
659 <title>Choosing a license</title>
662 Any discussion of licenses is also sure to generate at least a
663 small flame war as there are strong feelings that some free
664 software licenses are better than others. This discussion also
665 brings up the question of <quote>Open Source Software</quote> and
666 the debate over the terms <quote>Open Source Software</quote> and
667 <quote>Free Software</quote>. However, because I've written the
668 Free Software Project Management HOWTO and not the Open Source
669 Software Project Management HOWTO, my own allegiances in this
670 argument are in the open.
674 In attempting to reach a middle ground through diplomacy without
675 sacrificing my own philosophy, I will recommend picking any
676 license that conforms to the <ulink
677 url="http://www.debian.org/social_contract">Debian Free Software
678 Guidelines</ulink>. Originally compiled by the Debian project
679 under Bruce Perens, the <acronym>DFSG</acronym> forms the first
680 version of the <ulink
681 url="http://www.opensource.org/docs/definition_plain.html">Open
682 Source Definition.</ulink> Examples of free licenses given by the
683 <acronym>DFSG</acronym> are the <acronym>GPL</acronym>, the
684 <acronym>BSD</acronym>, and the Artistic License.
688 Conforming to the definition of free software offered by Richard
690 url="http://www.gnu.org/philosophy/free-sw.html"><quote>The Free
691 Software Definition</quote></ulink>, any of these licenses will
692 uphold, <quote>users' freedom to run, copy, distribute, study,
693 change and improve the software.</quote> There are plenty of
694 other licenses that also conform to the <acronym>DFSG</acronym>
695 but sticking with a more well-known license will offer the advantage
696 of immediate recognition and understanding.
700 In attempting a more in-depth analysis, I agree with Karl Fogel's
701 description of licenses as falling into two groups: those that
702 are the <acronym>GPL</acronym> and those that are not the
703 <acronym>GPL</acronym>.
707 Personally, I license all my software under the
708 <acronym>GPL</acronym>. Created and protected by the Free
709 Software Foundation and the GNU Project, the
710 <acronym>GPL</acronym> is the license for the Linux kernel,
711 GNOME, Emacs, and the vast majority of GNU/Linux software. It's
712 the obvious choice but I also believe it is a good one. Any BSD
713 fanatic will urge you to remember that there is a viral aspect to
714 the <acronym>GPL</acronym> that prevents the mixture of
715 <acronym>GPL</acronym>'ed code with non-<acronym>GPL</acronym>'ed
716 code. To many people (myself included), this is a benefit, but to
717 some, it is a major drawback.
721 The three major licenses can be found at the following locations:
727 <para><ulink url="http://www.gnu.org/copyleft/gpl.html">The GNU
728 General Public License</ulink></para>
731 <para><ulink url="http://www.debian.org/misc/bsd.license">The
732 BSD License</ulink></para>
736 url="http://language.perl.com/misc/Artistic.html">The Artistic
737 License</ulink></para>
743 <emphasis>In any case, please read through any license before
744 your release your software under it. As the primary developer,
745 you can't afford any license surprises.</emphasis>

753 The text of the <acronym>GPL</acronym> offers <ulink

857 <title>Choosing a Method of Version Numbering</title>
860 <emphasis>The most important thing about a system of version
861 numbering is that there is one.</emphasis> It may seem pedantic to
862 emphasize this point but you'd be surprised at the number of
863 scripts and small programs that pop up without any version number
868 <emphasis>The second most important thing about a system of
869 numbering is that the numbers always go up.</emphasis> Automatic
870 version tracking systems and people's sense of order in the
871 universe will fall apart if version numbers don't rise. It doesn't
872 <emphasis>really</emphasis> matter if 2.1 is a big jump and
873 2.0.005 is a small jump but it does matter that 2.1 is more recent
878 Follow these two simple rules and you will not go (too)
879 wrong. Beyond this, the most common technique seems to be the
880 <quote>major level,</quote> <quote>minor level,</quote>
881 <quote>patch level</quote> version numbering scheme. Whether you
882 are familiar with the name or not, you interact with it all the
883 time. The first number is the major number and it signifies major
884 changes or rewrites. The second number is the minor number and it
885 represents added or tweaked functionality on top of a largely
886 coherant structure. The third number is the patch number and it
887 usually will only refer to releases fixing bugs.
891 The widespread use of this scheme is why I know the nature and
892 relative degree in the differences between a 2.4.12 release of the
893 Linux kernel and a 2.4.11, 2.2.12, and 1.2.12 without knowning
894 anything about any of the releases.
898 You can bend or break these rules, and people do. But beware, if
899 you choose to, someone will get annoyed, assume you don't know,
900 and try and educate you, probably not nicely. I always follow this
901 method and I implore you to do so as well.
905 There are several version numbering systems that are well known,
906 useful, and that might be worth looking into before you release
912 <term>Linux kernel version numbering:</term>
914 <para>The Linux kernel uses a versioning system where any odd
915 minor version number refers to an development or testing release
916 and any even minor version number refers to a stable
917 version. Think about it for a second. Under this system, 2.1 and
918 2.3 kernels were and always will be development or testing
919 kernels and 2.0, 2.2. and 2.4 kernels are all production code
920 with a higher degree of stability and more testing.
924 Whether you plan on having a split development model (as
925 described in <xref linkend="branches">) or only one version
926 released at a time, my experience with several free software
927 projects and with the Debian project has taught me that use of
928 Linux's version numbering system is worth taking into
929 consideration. In Debian, <emphasis>all</emphasis> minor
930 versions are stable distributions (2.0, 2.1, etc). However,
931 many people assume that 2.1 is an unstable or development
932 version and continue to use an older version until they get so
933 frustrated with the lack of development progress that they
934 complain and figure the system out. If you never release an odd
935 minor version but only release even ones, nobody is hurt, and
936 less people are confused. It's an idea worth taking into
943 <term>Wine version numbering:</term>
945 <para>Because of the unusual nature of wine's development where
946 the not-emulator is constantly improving but not working towards
947 any immediately achievable goal, wine is released every three
948 weeks. Wine does this by labeling their releases in <quote>Year
949 Month Day</quote> format where each release might be labeled
950 <quote>wine-XXXXXXXX</quote> where the version from January 04,
951 2000 would be <quote>wine-20000104</quote>. For certain
952 projects, <quote>Year Month Day</quote> format can make a lot of
959 <term>Mozilla milestones:</term>
961 <para>When one considers Netscape 6 and vendor versions, the
962 mozilla's project development structure is one of the most
963 complex free software models available. The project's version
964 numbering has reflected the unique situation in which it is
969 Mozilla's version numbering structure has historically been
970 made up of milestones. From the beginning of the mozilla
971 project, the goals of the project in the order and degree to
972 which they were to be achieved were charted out on a series of
973 <ulink url="http://www.mozilla.org/roadmap.html">road
974 maps</ulink>. Major points and achievements along these
975 road-maps were marked as milestones. Therefore, although
976 mozilla was built and distributed nightly as <quote>nightly
977 builds,</quote> on a day when the goals of a milestone on the
978 road-map had been reached, that particular build was marked as
979 a <quote>milestone release.</quote>
983 While I haven't seen this method employed in any other projects
984 to date, I like the idea and think that it might have value in
985 any testing or development branch of a large application under
994 <!-- Section2: documentation-->
996 <sect2 id="documentation">
997 <title>Documentation</title>
1000 A huge number of otherwise fantastic free software applications
1001 have withered and died because their author was the only person
1002 who knew how to use them fully. Even if your program is written
1003 primarily for a techno-savvy group of users, documentation is
1004 helpful and even necessary for the survival of your project. You
1005 will learn later in <xref linkend="releasing"> that you should
1006 always release something that is usable. <emphasis>A piece of
1007 software without documentation is not usable.</emphasis>
1011 There are lots of different people you should document for and
1012 there are lots of ways to document your project. <emphasis>The
1013 importance of documentation in source code to help facilitate
1014 development by a large community is vital</emphasis> but it falls
1015 outside the scope of this HOWTO. This being the case, this section
1016 deals with useful tactics for user-directed documentation.
1020 A combination of tradition and necessity has resulted in a
1021 semi-regular system of documentation in most free software
1022 projects that is worth following. Both users and developers expect
1023 to be able to get documentation in several ways and it's essential
1024 that you provide the information they are seeking in a form they
1025 can read if your project is ever going to get off the
1026 ground. People have come to expect:
1030 <title>Man pages</title>
1032 <para>Your users will want to be able to type <quote>man
1033 yourprojectname</quote> end up with a nicely formatted man page
1034 highlighting the basic use of your application. Make sure that
1035 before you release your program, you've planned for this.
1039 Man pages are not difficult to write. There is excellent
1040 documentation on the man page writing process available through
1041 the <quote>The Linux Man-Page-HOWTO</quote> which is available
1042 through the Linux Documentation project <acronym>(LDP)</acronym>
1043 and is written by Jens Schweikhardt. It is available <ulink
1044 url="http://www.schweikhardt.net/man_page_howto.html">from
1045 Schweikhardt's site</ulink> or <ulink
1046 url="http://www.linuxdoc.org/HOWTO/mini/Man-Page.html">from the
1047 <acronym>LDP</acronym></ulink>.
1051 It is also possible to write man pages using DocBook
1052 SGML. Because man pages are so simple and the DocBook method
1053 relatively new, I have not been able to follow this up but would
1054 love help from anyone who can give me more information on how
1055 exactly how this is done.
1060 <title>Command line accessible documentation</title>
1063 Most users will expect some basic amount of documentation to be
1064 easily available from the command line. For few programs should
1065 this type of documentation extend for more than one screen (24 or
1066 25 lines) but it should cover the basic usage, a brief (one or
1067 two sentence) description of the program, a list of the commands
1068 with explanations, as well as all the major options (also with
1069 explanations), plus a pointer to more in-depth documentation for
1070 those who need it. The command line documentation for Debian's
1071 apt-get serves as an excellent example and a useful model:
1075 apt 0.3.19 for i386 compiled on May 12 2000 21:17:27
1076 Usage: apt-get [options] command
1077 apt-get [options] install pkg1 [pkg2 ...]
1079 apt-get is a simple command line interface for downloading and
1080 installing packages. The most frequently used commands are update
1084 update - Retrieve new lists of packages
1085 upgrade - Perform an upgrade
1086 install - Install new packages (pkg is libc6 not libc6.deb)
1087 remove - Remove packages
1088 source - Download source archives
1089 dist-upgrade - Distribution upgrade, see apt-get(8)
1090 dselect-upgrade - Follow dselect selections
1091 clean - Erase downloaded archive files
1092 autoclean - Erase old downloaded archive files
1093 check - Verify that there are no broken dependencies
1097 -q Loggable output - no progress indicator
1098 -qq No output except for errors
1099 -d Download only - do NOT install or unpack archives
1100 -s No-act. Perform ordering simulation
1101 -y Assume Yes to all queries and do not prompt
1102 -f Attempt to continue if the integrity check fails
1103 -m Attempt to continue if archives are unlocatable
1104 -u Show a list of upgraded packages as well
1105 -b Build the source package after fetching it
1106 -c=? Read this configuration file
1107 -o=? Set an arbitary configuration option, eg -o dir::cache=/tmp
1108 See the apt-get(8), sources.list(5) and apt.conf(5) manual
1109 pages for more information and options.
1113 It has become a GNU convention to make this type of information
1114 accessible with the <quote>-h</quote> and the
1115 <quote>--help</quote> options. Most GNU/Linux users will expect
1116 to be able to retrieve basic documentation these ways so if you
1117 choose to use different methods, be prepared for the flames and
1118 fallout that may result.
1123 <title>Files users will expect</title>
1125 In addition to man pages and command-line help, there are certain
1126 files where people will look for documentation, especially in any
1127 package containing source code. In a source distribution, most of
1128 these files can be stored in the root directory of the source
1129 distribution or in a subdirectory of the root called
1130 <quote>doc</quote> or <quote>Documentation.</quote> Common files
1131 in these places include:
1137 <term>README or Readme</term>
1140 <para>A document containing all the basic installation,
1141 compilation, and even basic use instructions that make up the
1142 bare minimum information needed to get the program up and
1143 running. A README is not your chance to be verbose but should
1144 be concise and effective. An ideal README is at least 30 lines
1145 long and more no more than 250.</para>
1150 <term>INSTALL or Install</term>
1153 <para>The INSTALL file should be much shorter than the README
1154 file and should quickly and concisely describe how to build
1155 and install the program. Usually an INSTALL file simply
1156 instructs the user to run <quote>./configure; make; make
1157 install</quote> and touches on any unusual options or actions
1158 that may be necessary. For most relatively standard install
1159 procedures and for most programs, INSTALL files are as short
1160 as possible and are rarely over 100 lines.</para>
1165 <term>CHANGELOG, Changelog, ChangeLog, or changelog</term>
1168 <para>A CHANGELOG is a simple file that every well-managed
1169 free software project should include. A CHANGELOG is simple
1170 the file that, as its name implies, logs or documents the
1171 changes you make to your program. The most simple way to
1172 maintain a CHANGELOG is to simply keep a file with the source
1173 code for your program and add a section to the top of the
1174 CHANGELOG with each release describing what has been changed,
1175 fixed, or added to the program. It's a good idea to post the
1176 CHANGELOG onto the website as well because it can help people
1177 decide whether they want or need to upgrade to a newer version
1178 or wait for a more significant improvement.</para>
1186 <para>A NEWS file and a ChangeLog are similar. Unlike a
1187 CHANGELOG, a NEWS file is not typically updated with new
1188 versions. Whenever new features are added, the developer
1189 responisble will make a note in the NEWS file. NEWS files
1190 should not have to be changed before a release (they should be
1191 kept up to date all along) but it's usually a good idea to
1192 check first anyway because often developers just forget to
1193 keep them as current as they should.</para>
1198 <term><acronym>FAQ</acronym></term>
1201 <para>For those of you that don't already know,
1202 <acronym>FAQ</acronym> stands for Frequently Asked Questions
1203 and a FAQ is a collection of exactly that. FAQs are not
1204 difficult to make. Simply make a policy that if you are asked
1205 a question or see a question on a mailing list two or more
1206 times, add the question (and its answer) to your FAQ. FAQs are
1207 more optional than the files listed above but they can save
1208 your time, increase usability, and decrease headaches on all
1218 <title>Website</title>
1220 It's only indirectly an issue of documentation but a good website
1221 is quickly becoming an essential part of any free software
1222 project. Your website should provide access to your documentation
1223 (in <acronym>HTML</acronym> if possible). It should also include
1224 a section for news and events around your program and a section
1225 that details the process of getting involved with development or
1226 testing and make an open invitation. It should also supply links
1227 to any mailing lists, similar websites, and provide a direct link
1228 to all the available ways of downloading your software.
1233 <title>Other documentation hints</title>
1236 All your documentation should be in plaintext, or, in cases where
1237 it is on your website primarily, in HTML. Everyone can cat a
1238 file, everyone has a pager, (almost) everyone can render
1239 HTML. <emphasis>You are welcome to distribute information in PDF,
1240 PostScript, RTF, or any number of other widely used formats but
1241 this information must also be available in plaintext or HTML or
1242 people will be very angry at you.</emphasis>
1246 It doesn't hurt to distribute any documentation for your program
1247 from your website (FAQs etc) with your program. Don't hesitate to
1248 throw any of this in the program's tarball. If people don't need
1249 it, they will delete it. I can repeat it over and over:
1250 <emphasis>Too much documentation is not a sin.</emphasis>
1255 <!-- Section2: presentation -->
1257 <sect2 id="presentation">
1258 <title>Other Presentation Issues</title>
1260 Many of the remaining issues surrounding the creation of a new
1261 free software program fall under what most people describe as
1262 common sense issues. Its often said that software engineering is
1263 90 percent common sense combined with 10 percent specialized
1264 knowledge. Still, they are worth noting briefly in hopes that they
1265 may remind a developer of something they may have forgotten.
1269 <title>Package formats</title>
1271 Package formats may differ depending on the system you are
1272 developing for. For windows based software, Zip archives (.zip)
1273 usually serve as the package format of choice. If you are
1274 developing for GNU/Linux, *BSD, or any UN*X, make sure that your
1275 source code is always available in tar'ed and gzip'ed format
1276 (.tar.gz). UNIX compress (.Z) has gone out of style and
1277 usefulness and faster computers have brought bzip2 (.bz2) into
1278 the spot-light as a more effective compression medium. I now make
1279 all my releases available in both gzip'ed and bzip2'ed tarballs.
1283 Binary packages should always be distribution specific. If you
1284 can build binary packages against a current version of a major
1285 distribution, you will only make your users happy. Try to foster
1286 relationships with users or developers of large distributions to
1287 develop a system for the consistent creation of binary
1288 packages. It's often a good idea to provide RedHat
1289 <acronym>RPM</acronym>'s (.rpm), Debian deb's (.deb) and source
1290 <acronym>RPM</acronym>'s <acronym>SRPM</acronym>'s if
1291 possible. Remember: <emphasis>While these binaries packages are
1292 nice, getting the source packaged and released should always be
1293 your priority. Your users or fellow developers can and will do
1294 the the binary packages for you.</emphasis>
1299 <title>Version control systems</title>
1302 A version control system can make a lot of these problems of
1303 packaging (and a lot of other problems mentioned in this HOWTO)
1304 less problematic. If you are using *NIX, CVS is your best bet. I
1305 recommend Karl Fogel's book on the subject (and the <ulink
1306 url="http://cvsbook.red-bean.com/">posted HTML version</ulink>)
1311 CVS or not, you should probably invest some time into learning
1312 about a version control system because it provides an automated
1313 way of solving many of the problems described by this HOWTO. I
1314 am not aware of any free version control systems for Windows or
1315 MacOS but I know that CVS clients exist for both
1316 platforms. Websites like <ulink
1317 url="http://sourceforge.net">SourceForge</ulink> do a great job
1318 as well with a nice, easy-to-use web interface to CVS.
1322 I'd love to devote more space in this HOWTO to CVS because I love
1323 it (I even use CVS to keep versions straight on this HOWTO!) but
1324 I think it falls outside the scope of this document and should have
1325 (already has) its own HOWTO.
1331 <title>Useful tidbits and presentation hints</title>
1334 Other useful hints include:
1342 <emphasis>Make sure that your program can always be found in a
1343 single location.</emphasis> Often this means that you have a
1344 single directory accessible via <acronym>FTP</acronym> or the
1345 web where the newest version can be quickly recognized. One
1346 effective technique is a provide a symlink called
1347 <quote>yourprojectname-latest</quote> that is always pointing
1348 to the most recent released or development version of your
1349 free software application. Keep in mind that this location
1350 will recieve many requests for downloads around releases so
1351 make sure that the server you choose has adequate bandwidth.
1357 <emphasis>Make sure that there is a consistent email address
1358 for bug reports.</emphasis> It's usually a good idea to make
1359 this something that is NOT your primary email address like
1360 yourprojectname@host or yourprojectname-bugs@host. This way,
1361 if you ever decide to hand over maintainership or if your
1362 email address changes, you simply need to change where this
1363 email address forwards. It also will allow for more than one
1364 person to deal with the influx of mail that is created if your
1365 project becomes as huge as you hope it will.

1380 <title>Maintaining a Project: Interacting with Developers</title>
1382 <primary>fswd!developers</primary>
1386 Once you have gotten your project started, you have overcome the
1387 most difficult hurdles in the development process of your
1388 program. Laying a firm foundation is essential, but the development
1389 process itself is equally important and provides just as many
1390 opportunities for failure. In the next two sections, I will
1391 describe running a project by discussing how to maintain a
1392 development effort through interactions with developers and with
1397 In releasing your program, your program becomes free software. This
1398 transition is more than just a larger user base. By releasing your
1399 program as free software, <emphasis>your</emphasis> software
1400 becomes the <emphasis>free software community's</emphasis>
1401 software. The direction of your software's development will be
1402 reshaped, redirected, and fully determined by your users and, to a
1403 larger extent, by other developers in the community.
1407 The major difference between free software development and
1408 propriety software development is the developer base. As the leader
1409 of a free software project, you need to attract and keep developers
1410 in a way that leaders of proprietary software projects simply don't
1411 have to worry about. <emphasis>As the person leading development of
1412 a free software project, you must harness the work of fellow
1413 developers by making responsible decisions and by responsibly
1414 choosing not to make decisions. You have to direct developers
1415 without being overbearing or bossy. You need to strive to earn
1416 respect and never forget to give it out.</emphasis>
1419 <!-- Section2: delegation -->
1421 <sect2 id="delegation">
1422 <title>Delegating Work</title>
1425 By now, you've hypothetically followed me through the early
1426 programming of a piece of software, the creation of a website and
1427 system of documentation, and we've gone ahead and (as will be
1428 discussed in <xref linkend="releasing">) released it to the rest
1429 of the world. Times passes, and if things go well, people become
1430 interested and want to help. The patches begin flowing in.
1434 <emphasis>Like the parent of any child who grows up, it's now time
1435 to wince, smile and do most difficult thing in any parents
1436 life: It's time to let go.</emphasis>
1440 Delegation is the political way of describing this process of
1441 <quote>letting go.</quote> It is the process of handing some of
1442 the responsibility and power over your project to other
1443 responsible and involved developers. It is difficult for anyone
1444 who has invested a large deal of time and energy into a project
1445 but it essential for the growth of any free software project. One
1446 person can only do so much. A free software project is nothing
1447 without the involvement of <emphasis>a group</emphasis> of
1448 developers. A group of developers can only be maintained through
1449 respectful and responsible leadership and delegation.
1453 As your project progresses, you will notice people who are putting
1454 significant amounts of time and effort into your project. These
1455 will be the people submitting the most patches, posting most on
1456 the mailing lists, and engaging in long email discussions. It is
1457 your responsibility to contact these people and to try and shift
1458 some of the power and responsibility of your position as the
1459 project's maintainer onto them (if they want it). There are
1460 several easy ways you can do this:
1464 In a bit of a disclaimer, delegation need not mean rule by
1465 comittee. In many cases it does and this has been proven to
1466 work. In other cases this has created problems. <ulink
1467 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
1468 Projects the Open Source Way</ulink> argues that <quote>OSS
1469 projects do best when one person is the clear leader of a team and
1470 makes the big decisions (design changes, release dates, and so
1471 on).</quote> I think this often true but would urge developers to
1472 consider the ideas that the project leader need not be the
1473 project's founder and that these important powers need not all rest
1474 with one person but that a release manager may be different than a
1475 lead developer. These situations are tricky politically so
1476 be careful and make sure it's necessary before you go around
1481 <title>How to delegate</title>
1484 You may find that other developers seem even more experienced or
1485 knowledgeable than you. Your job as a maintainer does not mean
1486 you have to be the best or the brightest. It means you
1487 are responsible for showing good judgment and for
1488 recognizing which solutions are maintainable and which are not.
1491 Like anything, its easier to watch others delegate than to do it
1492 yourself. In a sentence: <emphasis>Keep an eye out for other
1493 qualified developers who show an interest and sustained
1494 involvement with your project and try and shift responsibility
1495 towards them.</emphasis> The following ideas might be good places
1496 to start or good sources of inspiration:

1515 is an extreme example of rule by committee. At current count,
1516 more than 700 developers have full responsibility for
1517 aspects of the project. All these developers can upload into
1518 the main FTP server, and vote on major issues. Direction for
1519 the project is determined by the project's <ulink
1520 url="http://www.debian.org/social_contract">social
1521 contract</ulink> and a <ulink
1522 url="http://www.debian.org/devel/constitution">constitution</ulink>. To
1523 facilitate this system, there are special teams (i.e. the
1524 install team, the Japanese language team) as well as a technical
1525 committee and a project leader. The leader's main responsibility
1526 is to, <quote>appoint delegates or delegate decisions to the
1527 Technical Committee.</quote>
1531 While both of these projects operate on a scale that your
1532 project will not (at least initially), their example is
1533 helpful. Debian's idea of a project leader who can do
1534 <emphasis>nothing</emphasis> but delegate serves as a
1535 caricature of how a project can involve and empower a huge
1536 number of developers and grow to a huge size.
1541 <sect4 id="releasemanager">
1542 <title>Publicly appoint someone as the release manager for a
1543 specific release</title>
1546 A release manager is usually responsible for coordinating
1547 testing, enforcing a code freeze, being responsible for
1548 stability and quality control, packaging up the software, and
1549 placing it in the appropriate places to be downloaded.
1553 This use of the release manager is a good way to give yourself a
1554 break and to shift the responsibility for accepting and
1555 rejecting patches onto someone else. It is a good way of very
1556 clearly defining a chunk of work on the project as belonging to
1557 a certain person and its a great way of giving yourself room to

1563 <title>Delegate control of an entire branch</title>
1565 If your project chooses to have branches (as described in <xref
1566 linkend="branches">), it might be a good idea to appoint someone
1567 else to be the the head of a branch. If you like focusing your
1568 energy on development releases and the implementation of new
1569 features, hand total control over the stable releases to a
1570 well-suited developer.
1574 The author of Linux, Linus Torvalds, came out and crowned Alan
1575 Cox as <quote>the man for stable kernels.</quote> All patches
1576 for stable kernels go to Alan and, if Linus were to be taken
1577 away from work on Linux for any reason, Alan Cox would be more
1578 than suited to fill his role as the acknowledged heir to the
1579 Linux maintainership.

1588 <title>Accepting and Rejecting Patches</title>
1590 This HOWTO has already touched on the fact that as the maintainer
1591 of a free software project, one of your primary and most important
1592 responsibilities will be accepting and rejecting patches submitted
1593 to you by other developers.
1597 <title>Technical judgment</title>
1600 In <emphasis>Open Source Development with CVS</emphasis>, Karl
1601 Fogel makes a convincing argument that the most important things
1602 to keep in mind when rejecting or accepting patches are:
1609 <para>A firm knowledge of the scope of your program (that's the
1610 <quote>idea</quote> I talked about in <xref linkend="chooseproject">);</para>
1614 <para>The ability to recognize, facilitate, and direct
1615 <quote>evolution</quote> of your program so that the program
1616 can grow and change and incorporate functionality that was
1617 originally unforeseen;</para>
1621 <para>The necessity to avoid digressions that might expand the
1622 scope of the program too much and result and push the project
1623 towards an early death under its own weight and
1624 unwieldiness.</para>
1631 These are the criteria that you as a project maintainer should
1632 take into account each time you receive a patch.
1636 Fogel elaborates on this and states the <quote>the
1637 questions to ask yourself when considering whether to implement
1638 (or approve) a change are:</quote>
1645 <para>Will it benefit a significant percentage of the program's
1646 user community?</para>
1650 <para>Does it fit within the program's domain or within a
1651 natural, intuitive extension of that domain?</para>
1658 The answers to these questions are never straightforward and its
1659 very possible (and even likely) that the person who submitted the
1660 patch may feel differently about the answer to these questions
1661 than you do. However, if you feel that that the answer to either
1662 of those questions is <quote>no,</quote> it is your responsibility
1663 to reject the change. If you fail to do this, the project will
1664 become unwieldy and unmaintainable and many ultimately fail.
1669 <title>Rejecting patches</title>
1672 Rejecting patches is probably the most difficult and sensitive
1673 job that the maintainer of any free software project has to
1674 face. But sometimes it has to be done. I mentioned earlier (in
1675 <xref linkend="developers"> and in <xref linkend="delegation">)
1676 that you need to try and balance your responsibility and power to
1677 make what you think are the best technical decisions with the
1678 fact that you will lose support from other developers if you seem
1679 like you are on a power trip or being overly bossy or possessive
1680 of the community's project. I recommend that you keep these three
1681 major concepts in mind when rejecting patches (or other changes):
1685 <title>Bring it to the community</title>
1687 One of the best ways of justifying a decision to reject a patch
1688 and working to not seem like you keep an iron grip on your
1689 project is by not making the decision alone at all. It might
1690 make sense to turn over larger proposed changes or more
1691 difficult decisions to a development mailing list where they can
1692 be discussed and debated. There will be some patches (bug fixes,
1693 etc.) which will definitely be accepted and some that you feel
1694 are so offbase that they do not even merit further
1695 discussion. It is those that fall into the grey area between
1696 these two groups that might merit a quick forward to a mailing
1701 I recommend this process wholeheartedly. As the project
1702 maintainer you are worried about making the best decision for
1703 the project, for the project's users and developers, and for
1704 yourself as a responsible project leader. Turning things over to
1705 an email list will demonstrate your own responsibility and
1706 responsive leadership as it tests and serves the interests of
1707 your software's community.
1712 <title>Technical issues are not always good justification</title>
1714 Especially towards the beginning of your project's life, you
1715 will find that many changes are difficult to implement,
1716 introduce new bugs, or have other technical problems. Try to see
1717 past these. Especially with added functionality, good ideas do
1718 not always come from good programmers. Technical merit is a
1719 valid reason to postpone an application of a patch but it is not
1720 always a good reason to reject a change outright. Even small
1721 changes are worth the effort of working with the developer
1722 submitting the patch to iron out bugs and incorporate the change
1723 if you think it seems like a good addition to your project. The
1724 effort on your part will work to make your project a community
1725 project and it will pull a new or less experienced developer
1726 into your project and even teach them something that might help
1727 them in making their next patch.
1732 <title>Common courtesy</title>
1734 It should go without saying but, <emphasis>above all and in all
1735 cases, just be nice.</emphasis> If someone has an idea and cares
1736 about it enough to write some code and submit a patch, they
1737 care, they are motivated, and they are already involved. Your
1738 goal as the maintainer is make sure they submit again. They may
1739 have thrown you a dud this time but next time may be the idea or
1740 feature that revolutionizes your project.
1744 It is your responsibility to first justify your choice to not
1745 incorporate their change clearly and concisely. Then thank
1746 them. Let them know that you a appreciate their help and feel
1747 horrible that you can't incorporate their change. Let them know
1748 that you look forward to their staying involved and you hope
1749 that the next patch or idea meshes better with your project
1750 because you appreciate their work and want to see it in your
1751 application. If you have ever had a patch rejected after putting
1752 a large deal of time, thought, and energy into it, you remember
1753 how it feels and it feels bad. Keep this in mind when you have
1754 to let someone down. It's never easy but you need to do
1755 everything you can to make it as not-unpleasant as possible.
1761 <!-- Section2: branches -->
1763 <sect2 id="branches">
1764 <title>Stable and Development Branches</title>
1767 The idea of stable and development branches has already been
1768 described briefly in <xref linkend="chooseversioning"> and in
1769 <xref linkend="delegatebranch">. These allusions attest to some of
1770 the ways that multiple branches can affect your software. Branches
1771 can let you avoid (to some extent) some of the problems around
1772 rejecting patches (as described in <xref linkend="patching">) by
1773 allowing you to temporarily compromise the stability of your
1774 project without affecting those users who need that stability.
1778 The most common way of branching your project is to have one
1779 branch that is stable and one that is for development. This is the
1780 model followed by the Linux kernel that is described in <xref
1781 linkend="chooseversioning">. In this model, there is
1782 <emphasis>always</emphasis> one branch that is stable and always
1783 one that is in development. Before any new release, the
1784 development branch goes into a <quote>feature freeze</quote> as
1785 described in <xref linkend="freezing"> where major changes and
1786 added features are rejected or put on hold under the development
1787 kernel is released as the new stable branch and major development
1788 resumes on the development branch. Bug fixes and small changes
1789 that are unlikely to have any large negative repercussions are
1790 incorporated into the stable branch as well as the development
1795 Linux's model provides an extreme example. On many projects, there is no
1796 need to have two versions constantly available. It may make sense to
1797 have two versions only near a release. The Debian project has
1798 historically made both a stable and an unstable distribution
1799 available but has expanded to this to include: stable, unstable,
1800 testing, experimental, and (around release time) a frozen
1801 distribution that only incorporates bug fixes during the
1802 transition from unstable to stable. There are few projects whose
1803 size would necessitate a system like Debian's but this use of
1804 branches helps demonstrate how they can be used to balance
1805 consistent and effective development with the need to make regular
1806 and usable releases.
1810 In trying to set up a development tree for yourself, there are
1811 several things that might be useful to keep in mind:
1818 <term>Minimize the number of branches</term>
1820 <para>Debian may be able to make good use of four or five
1821 branches but it contains gigabytes of software in over 5000
1822 packages compiled for 5-6 different architectures. For you,
1823 two is probably a good ceiling. Too many branches will confuse
1824 your users (I can't count how many times I had to describe
1825 Debian's system when it only had 2 and sometimes 3 branches!),
1826 potential developers and even yourself. Branches can help but
1827 they come at a cost so use them very sparingly.</para>
1832 <term>Make sure that all your different branches are explained</term>
1834 <para>As I mentioned in the preceding paragraph, different
1835 branches <emphasis>will</emphasis> confuse your users. Do
1836 everything you can to avoid this by clearly explaining the
1837 different branches in a prominent page on your website and in a
1838 README file in the <acronym>FTP</acronym> or
1839 web directory.</para>
1842 I might also recommend against a mistake that I think Debian
1843 has made. The terms <quote>unstable,</quote>
1844 <quote>testing,</quote> and <quote>experimental</quote> are
1845 vague and difficult to rank in order of stability (or
1846 instability as the case may be). Try explaining to someone
1847 that <quote>stable</quote> actually means <quote>ultra
1848 stable</quote> and that <quote>unstable</quote> doesn't
1849 actually include any unstable software but is really stable
1850 software that is untested as a distribution.
1854 If you are going to use branches, especially early on, keep in
1855 mind that people are conditioned to understand the terms
1856 <quote>stable</quote> and <quote>development</quote> and you
1857 probably can't go wrong with this simple and common division of
1864 <term>Make sure all your branches are always available</term>
1866 <para>Like a lot of this document, this should probably should
1867 go without saying but experience has taught me that it's not
1868 always obvious to people. It's a good idea to physically split
1869 up different branches into different directories or directory
1870 trees on your <acronym>FTP</acronym> or web site. Linux
1871 accomplishes this by having kernels in a v2.2 and a v2.3
1872 subdirectory where it is immediately obvious (after you know
1873 their version numbering scheme) which directory is for the most
1874 recent stable and the current development releases. Debian
1875 accomplishes this by naming all their distribution with names
1876 (i.e. woody, potato, etc.) and then changing symlinks named
1877 <quote>stable,</quote> <quote>unstable</quote> and
1878 <quote>frozen</quote> to point to which ever distribution (by
1879 name) is in whatever stage. Both methods work and there are
1880 others. In any case, it is important that different branches
1881 are always available, are accessible from consistent locations,
1882 and that different branches are clearly distinguished from each
1883 other so your users know exactly what they want and where to

1896 <title>Other Project Management issues</title>
1898 There are more issues surrounding interaction with developers in a
1899 free software project that I can not touch on in great detail in a
1900 HOWTO of this size and scope. Please don't hesitate to contact me if you see
1901 any major omissions.
1905 Other smaller issues that are worth mentioning are:
1908 <sect3 id="freezing">
1909 <title>Freezing</title>
1911 For those projects that choose to adopt a split development model
1912 (<xref linkend="branches">), freezing is a concept that is worth
1913 becoming familiar with.
1917 Freezes come in two major forms. A <quote>feature freeze</quote>
1918 is a period when no significant functionality is added to a
1919 program. It is a period where established functionality (even
1920 skeletons of barely working functionality) can be improved and
1921 perfected. It is a period where bugs are fixed. This type of
1922 freeze is usually applied some period (a month or two) before a
1923 release. It is easy to push a release back as you wait for
1924 <quote>one more feature</quote> and a freeze helps to avoid this
1925 situation by drawing the much needed line in the sand. It gives
1926 developers room they need to get a program ready for release.
1930 The second type of freeze is a <quote>code freeze</quote> which
1931 is much more like a released piece of software. Once a piece of
1932 software has entered a <quote>code freeze,</quote> all changes to
1933 the code are discouraged and only changes that fix known bugs
1934 are permitted. This type of freeze usually follows a
1935 <quote>feature freeze</quote> and directly precedes a
1936 release. Most released software is in what could be interpreted
1937 as a sort of high level <quote>code freeze.</quote>
1941 Even if you never choose to appoint a release manager (<xref
1942 linkend="releasemanager">), you will have an easier time
1943 justifying the rejection or postponement of patches (<xref
1944 linkend="patching">) before a release with a publicly stated
1951 <title>Forks</title>
1953 I wasn't sure about how I would deal with forking in this
1954 document (or if I would deal with forking at all). A fork is when
1955 a group of developers takes code from a free software project and
1956 actually starts a brand new free software project with it. The
1957 most famous example of a fork was between Emacs and XEmacs. Both
1958 emacsen are based on an identical code-base but for technical,
1959 political, and philosophical reasons, development was split into
1960 two projects which now compete with each other.
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

1986 <title>Maintaining a Project: Interacting with Users</title>
1988 <primary>fswd!users</primary>
1992 If you've worked your way up to here, congratulations, you are
1993 nearing the end of this document. This final section describes some
1994 of the situations in which you, in your capacity as project
1995 maintainer, will be interacting with users. It gives some
1996 suggestions on how these situations might be handled effectively.
2000 Interacting with users is difficult. In our discussion of
2001 interaction with developers, the underlying assumption is that in a
2002 free software project, a project maintainer must constantly strive to
2003 attract and keep developers who can easily leave at any time.
2007 Users in the free software community are different than developers
2008 and are also different than users in the world of proprietary
2009 software and they should be treated differently than either
2010 group. Some ways in which the groups differ significantly follow:
2017 <para>The lines between users and developers are blurred in ways
2018 that is totally foreign to any proprietary development
2019 model. Your users are often your developers and vice
2024 <para>In the free software world, you are often your users' only
2025 choice. Because there is such an emphasis on not replicating the
2026 work of others in the free software community and because the
2027 element of competition present in the propriety software model is
2028 absent (or at least in an extremely different form) in the free
2029 software development model, you will probably be the only project
2030 that does what you do (or at least the only one that does what
2031 you do in the way that you do it). This means your responsiveness
2032 to your users is even more important than in the proprietary
2033 software world.</para>
2037 <para>In an almost paradoxical situation, free software projects
2038 have less immediate or dire consequences for ignoring their users
2039 altogether. It is also often easier to do. Because you don't
2040 usually need to compete with another product, chances are good
2041 that you will not be scrambling to gain the features of your
2042 competitor's newest program. This means that your development
2043 process will have to be directed either internally, by a
2044 commitment to your users, or through both.</para>
2050 Trying to tackle this unique situation can only be done
2051 indirectly. Developers and maintainers need to listen to users and
2052 to try and be as responsive as possible. A solid knowledge of the
2053 situation recounted above is any free software developer's best tool
2054 for shifting his development or leadership style to fit the unique
2055 process of free software project management. This chapters will try and
2056 introduce some of the more difficult or important points in any
2057 projects interactions with users and give some hints on how to

2063 <sect2 id="testing">
2064 <title>Testing and Testers</title>
2067 In addition to your users being your developers, they are also
2068 (and perhaps more commonly) your testers. Before I get flamed, I
2069 should rephrase my sentence: <emphasis>some of your
2070 users</emphasis> (those who explicityly volunteer) are your
2075 It is important that this distinction be made early on because not
2076 all of your users want to be testers. Many users want to use
2077 stable software and don't care if they don't have the newest,
2078 greatest software with the latest, greatest features. These users
2079 except a stable, tested piece of software without major or obvious
2080 bugs and will be angry if they find themselves testing. This is
2081 yet another way in which a split development model (as mentioned
2082 in <xref linkend="branches">) might come in handy.

2123 of why it crashed or failed so that the user or developer
2124 understands whats going on.</para>
2130 <term>Standards conformance</term>
2133 <para>If possible, make sure your programs conforms to
2134 standards. If it's interactive, don't be too creative with
2135 interfaces. If it is non-interactive, make sure it communicates
2136 over appropriate and established channels with other programs
2137 and with the rest of the system.</para>
2144 <title>Automated testing</title>
2146 For many programs, many common mistakes can be caught by
2147 automated means. Automated tests tend to be pretty good at
2148 catching errors that you've run into several times before or
2149 the things you just forget. They are not very good at finding
2150 errors, even major ones, that are totally unforeseen.
2154 CVS comes with a bourne shell script called sanity.sh that is
2155 worth looking at. Debian uses a program called lintian that
2156 checks Debian packages for all of the most common errors. While
2157 use of these scripts may not be helpful, there is a host of other
2158 sanity checking software on the net that may be applicable (feel
2159 free to email me any recommendations). None of these will create
2160 a bug-free release but they will avoid at least some major
2161 oversights. Finally, if your programs become a long term
2162 endeavor, you will find that there are certain errors that you
2163 tend to make over and over. Start a collection of scripts that
2164 check for these errors to help keep them out of future releases.
2169 <title>Testing by testers</title>
2171 For any program that depends on user interactivity, many bugs
2172 will only be uncovered through testing by users actually clicking
2173 the keys and pressing the mouse buttons. For this you need
2174 testers and as many as possible.
2178 The most difficult part of testing is finding testers. It's
2179 usually a good tactic to post a message to a relevant mailing
2180 list or news group announcing a specific proposed release date
2181 and outlining the functionality of your program. If you put some
2182 time into the announcement, you are sure to get a few responses.
2186 The second most difficult part of testing is
2187 <emphasis>keeping</emphasis> your testers and keeping them
2188 actively involved in the testing process. Fortunately, there are
2189 some tried and true tactics that can applied towards this end:
2196 <term>Make things simple for your testers</term>
2198 <para>Your testers are doing you a favor so make it as easy as
2199 possible for them. This means that you should be careful to
2200 package your software in a way that is easy to find, unpack,
2201 install, and uninstall. This also means you should explain
2202 what you are looking for to each tester and make the means for
2203 reporting bugs simple and well established. The key is to
2204 provide as much structure as possible to make your testers'
2205 jobs easy and to maintain as much flexibility as possible for
2206 those that want to do things a little differently.</para>
2211 <term>Be responsive to your testers</term>
2213 <para>When your testers submit bugs, respond to them and
2214 respond quickly. Even if you are only responding to tell them
2215 that the bug has already been fixed, quick and consistent
2216 responses make them feel like their work is heard, important,
2217 and appreciated.</para>
2222 <term>Thank your testers</term>
2224 <para>Thank them personally each time they send you
2225 patch. Thank them publicly in the documentation and the about
2226 section of your program. You appreciate your testers and your
2227 program would not be possible without their help. Make sure
2228 they know it. Publicly, pat them on the back to make sure the rest of
2229 the world knows it too. It will be appreciated more than you

2247 and responsibility to your users falls under the category of
2248 support. The best way to make sure your users are adequately
2249 supported in using your program is to set up a good infrastructure
2250 for this purpose so that your developers and users help each other
2251 and less of the burden falls on you. This way, people will also
2252 get quicker and better responses to their questions. This
2253 infrastructure comes in several major forms:
2257 <title>Documentation</title>
2259 It should not come as any surprise that the key element to any
2260 support infrastructure is good documentation. This topic was
2261 largely covered in <xref linkend="documentation"> and will not be
2267 <title>Mailing lists</title>
2269 Aside from documentation, effective mailing lists will be your
2270 greatest tool in providing user support. Running a mailing list
2271 well is more complicated than installing mailing list software
2276 <title>Separate lists</title>
2279 A good idea is too separate your user and development mailing
2280 lists (perhaps into project-user@host and project-devel@host)
2281 and enforce the division. If people post a development question
2282 onto -user, politely ask them to repost it onto -devel and vise
2283 versa. Subscribe yourself to both groups and encourage all
2284 primarily developers to do the same.
2288 This system provides so that no one person is stuck doing all of
2289 the support work and works so that users learn more about the
2290 program, they can help newer users with their questions.
2295 <title>Choose mailing list software well</title>
2297 Please don't make the selection of mailing list software
2298 impulsively. Please consider easy accessibility by users without
2299 a lot of technical experience so you want to be as easy as
2300 possible. Web accessibility to an archive of the list is also
2305 The two biggest free software mailing list programs are <ulink
2306 url="http://www.greatcircle.com/majordomo/">majordomo</ulink>
2307 and <ulink url="http://www.list.org/">GNU Mailman</ulink>. A
2308 long time advocate of majordomo, I would now recommend any
2309 project choose GNU Mailman. It fulfills the criteria listed
2310 above and makes it easier. It provides a good mailing
2311 list program for a free software project maintainer as opposed
2312 to a good mailing list application for a mailing list
2317 There are other things you want to take into consideration in
2318 setting up your list. If it is possible to gate your mailing
2319 lists to USENET and provide it in digest form as well as
2320 making them accessible on the web, you will please some users
2321 and work to make the support infrastructure slightly more
2328 <title>Other support ideas</title>
2331 A mailing list and accessible documentation are far from all you
2332 can do to set up good user support infrastructure. Be
2333 creative. If you stumble across something that works well, email me
2334 and I'll include it here.
2338 <title>Make your self accessible</title>
2340 You can not list too few methods to reach you. If you hang out
2341 in an <acronym>IRC</acronym> channel, don't hesitate to list it
2342 in your projects documentation. List email and snailmail
2343 addresses, and ways to reach you via <acronym>ICQ</acronym>,
2344 <acronym>AIM</acronym>, or Jabber if they apply.
2349 <title>Bug management software</title>
2351 For many large software projects, use of bug management software
2352 is essential to keep track of which bugs have been fixed, which
2353 bugs have not been fixed, and which bugs are being fixed by
2354 which people. Debian uses the <ulink
2355 url="http://bugs.debian.org">Debian Bug Tracking System</ulink>
2356 (<acronym>BTS</acronym>) although it may not be best choice for
2357 every project (it seems to currently be buckling under its own
2358 weight) As well as a damn good web browser, the mozilla project
2359 has spawned a sub-project resulting in a bug tracking system
2361 url="http://www.mozilla.org/projects/bugzilla/">bugzilla</ulink>
2362 which has become extremely possible and which I like a lot.
2366 These systems (and others like them) can be unwieldy so
2367 developers should be careful to not spend more time on the bug
2368 tracking system than on the bugs or the projects themselves. If
2369 a project continues to grow, use of a bug tracking system can
2370 provide an easy standard avenue for users and testers to report
2371 bugs and for developers and maintainers to fix them and track
2372 them in an orderly fashion.
2378 <!-- Section2: releasing -->
2380 <sect2 id="releasing">
2381 <title>Releasing Your Program</title>
2384 As mentioned earlier in the HOWTO, the first rule of releasing is,
2385 <emphasis>release something useful.</emphasis> Non-working or
2386 not-useful software will not attract anyone to your
2387 project. People will be turned off of your project and will be likely
2388 to simply gloss over it next time they see a new version
2389 announced. Half-working software, if useful, will intrigue people,
2390 whet their appetites for versions to come, and encourage them to
2391 join the development process.
2395 <title>When to release</title>
2398 Making the decision to release your software for the first time
2399 is an incredibly important and incredibly stressful decision. But
2400 it needs to done. My advice is to try and make something that
2401 is complete enough to be usable and incomplete enough to allow
2402 for flexibility and room for imagination by your future
2403 developers. It's not an easy decision. Ask for help on a local
2404 Linux User Group mailing list or from a group of developer
2409 One tactic is to first do an <quote>alpha</quote> or
2410 <quote>beta</quote> release as described below in <xref
2411 linkend="alphabeta">. However, most of the guidelines described
2416 <emphasis>When you feel in your gut that it is time and you feel
2417 you've weighed the situation well several times, cross your
2418 fingers and take the plunge.</emphasis>
2422 After you've released for the first time, knowing when to release
2423 becomes less stressful, but just as difficult to gauge. I like
2424 the criteria offered by Robert Krawitz in his article, <ulink
2425 url="http://www.advogato.org/article/196.html"><quote>Free
2426 Software Project Management</quote></ulink> for maintaining a
2427 good release cycle. He recommends that you ask yourself,
2428 <quote>does this release...</quote>
2434 <para>Contain sufficient new functionality or bug fixes to be
2435 worth the effort.</para>
2439 <para>Be spaced sufficiently far apart to allow the user time
2440 to work with the latest release.</para>
2444 <para>Be sufficiently functional so that the user can get work
2445 done (quality).</para>
2451 If the answer is yes to all of these questions, its probably time
2452 for a release. If in doubt, remember that asking for advice can't
2458 <title>How to release</title>
2461 If you've followed the guidelines described in this HOWTO up
2462 until this point, the mechanics of doing a release are going to
2463 be the easy part of releasing. If you have set up consistent
2464 distribution locations and the other infrastructure described in
2465 the preceding sections, releasing should be as simple as building
2466 the package, checking it once over, and uploading it into the
2467 appropriate place and then making your website reflect the
2472 <sect3 id="alphabeta">
2473 <title>Alpha, beta, and development releases</title>
2476 When contemplating releases, it worth considering the fact that
2477 not every release needs to be a full numbered release. Software
2478 users are accustomed to pre-releases but you must be careful to
2479 label these releases accurately or they will cause more problems then
2484 The observation is often made that many free software developers
2485 seem to be confused about the release cycle. <quote><ulink
2486 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
2487 Projects the Open Source Way</ulink></quote> suggests that you memorize
2488 the phrase, <quote>Alpha is not Beta. Beta is not Release</quote>
2489 and I'd agree that tis is a probably a good idea.
2496 <term>alpha releases</term>
2498 <para>Alpha software is feature-complete but sometimes only
2499 partially functional.</para>
2501 <para>Alpha releases are expected to be unstable, perhaps a
2502 little unsafe, but definitely usable. They
2503 <emphasis>can</emphasis> have known bugs and kinks that have
2504 yet to be worked out. Before releasing an alpha, be sure to
2505 keep in mind that <emphasis>alpha releases are still
2506 releases</emphasis> and people are not going to be expecting a
2507 nightly build from the CVS source. An alpha should work and
2508 have minimal testing and bug fixing already finished.</para>
2513 <term>beta releases</term>
2515 <para>Beta software is feature-complete and functional, but is
2516 in the testing cycle and still has a few bugs left to be
2519 <para>Beta releases are general expected to be usable and
2520 slightly unstable, although definitely <emphasis>not
2521 unsafe.</emphasis> Beta releases usually preclude a full
2522 release by under a month. They can contain small known bugs
2523 but no major ones. All major functionality should be fully
2524 implemented although the exact mechanics can still be worked
2525 out. Beta releases are great tool to whet the appetites of
2526 potential users by giving them a very realistic view of where
2527 your project is going to be in the very near future and can
2528 help keep interest by giving people
2529 <emphasis>something.</emphasis></para>
2534 <term>development releases</term>
2536 <para><quote>Development release</quote> is much a more vague
2537 term than <quote>alpha</quote> or <quote>beta</quote>. I
2538 usually choose to reserve the term for discussion of a
2539 development branch although there are other ways to use the
2540 term. So many in fact, that I feel the term has been
2541 cheapened. The popular window manager <ulink
2542 url="http://www.enlightenment.org">Enlightenment</ulink> has
2543 released <emphasis>nothing but</emphasis> development
2544 releases. Most often, the term is used to describe releases
2545 that are not even alpha or beta and if I were to release a
2546 pre-alpha version of a piece of software in order to keep
2547 interest in my project alive, this is probably how I would
2548 have to label it.</para>
2558 <!-- Section2: announcing -->
2560 <sect2 id="announcing">
2561 <title>Announcing Your Project</title>
2564 Well, you've done it. You've (at least for the purposes of this
2565 HOWTO) designed, built, and released your free software
2566 project. All that is left is for you to tell the world so they
2567 know to come and try it out and hopefully jump on board with
2568 development. If everything is in order as described above, this
2569 will be a quick and painless process. A quick announcement is all
2570 that it takes to put yourself on the free software community's
2575 <title>Mailing lists and USENET</title>
2577 Email is still the way that most people on the Internet get their
2578 information. Its a good idea to send a message announcing your
2579 program to any relevant mailing list you know of and any relevant
2580 USENET discussion group. Karl Fogel recommends that use you
2581 simple subject describing the fact that the message is an
2582 announcement, the name of the program, the version, and a
2583 half-line long description of its functionality. This way, any
2584 interested user or developer will be immediately attracted to
2585 your announcement. Fogel's example looks like:
2588 <screen>Subject: ANN: aub 1.0, a program to assemble USENET binaries</screen>
2591 The rest of the email should describe the programs functionality
2592 quickly and concisely in no more than two paragraphs and should
2593 provide links to the projects webpage and direct links to
2594 downloads for those that want to try it right away.
2598 You should repeat this announcement process consistently in the
2599 same locations for each subsequent release.
2604 <title>freshmeat.net</title>
2606 Mentioned earlier in <xref linkend="evalwhere">, in today's free
2607 software community, announcements of your project on freshmeat
2608 are almost more important than announcements on mailing lists.

2616 database. In addition to a large website, freshmeat provides a
2617 daily newsletter that highlights all the days releases and

2619 interesting new releases).

2822 I have spent a huge amount of time on advogato and I've gone

3094 <title>0. PREAMBLE</title>
3096 The purpose of this License is to make a manual, textbook, or
3097 other written document <quote>free</quote> in the sense of
3098 freedom: to assure everyone the effective freedom to copy and
3099 redistribute it, with or without modifying it, either
3100 commercially or noncommercially. Secondarily, this License
3101 preserves for the author and publisher a way to get credit for
3102 their work, while not being considered responsible for
3103 modifications made by others.
3107 This License is a kind of <quote>copyleft</quote>, which means
3108 that derivative works of the document must themselves be free in
3109 the same sense. It complements the GNU General Public License,
3110 which is a copyleft license designed for free software.
3114 We have designed this License in order to use it for manuals for
3115 free software, because free software needs free documentation: a
3116 free program should come with manuals providing the same
3117 freedoms that the software does. But this License is not limited
3118 to software manuals; it can be used for any textual work,
3119 regardless of subject matter or whether it is published as a
3120 printed book. We recommend this License principally for works
3121 whose purpose is instruction or reference.

3127 This License applies to any manual or other work that contains a
3128 notice placed by the copyright holder saying it can be

3143 A <quote>Secondary Section</quote> is a named appendix or a

3147 Document to the Document's overall subject (or to related
3148 matters) and contains nothing that could fall directly within
3149 that overall subject. (For example, if the Document is in part a
3150 textbook of mathematics, a Secondary Section may not explain any
3151 mathematics.) The relationship could be a matter of historical
3152 connection with the subject or with related matters, or of

3179 directly and straightforwardly with generic text editors or (for
3180 images composed of pixels) generic paint programs or (for

3221 copyright notices, and the license notice saying this License
3222 applies to the Document are reproduced in all copies, and that
3223 you add no other conditions whatsoever to those of this

3225 control the reading or further copying of the copies you make or
3226 distribute. However, you may accept compensation in exchange for
3227 copies. If you distribute a large enough number of copies you
3228 must also follow the conditions in <link

3247 Back-Cover Texts on the back cover. Both covers must also
3248 clearly and legibly identify you as the publisher of these
3249 copies. The front cover must present the full title with all
3250 words of the title equally prominent and visible. You may add
3251 other material on the covers in addition. Copying with changes
3252 limited to the covers, as long as they preserve the title of the

3254 conditions, can be treated as verbatim copying in other

3277 reasonably prudent steps, when you begin distribution of Opaque
3278 copies in quantity, to ensure that this Transparent copy will
