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

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

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

333 afforded by translated versions.
337 However, this HOWTO is still young and I have to yet to be
338 contacted about a translation so English is all that is currently
339 available. If you would like to help with or do a translation, you
340 will gain my utmost respect and admiration and you'll get to be

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

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

863 <title>Choosing a Method of Version Numbering</title>
866 <emphasis>The most important thing about a system of version
867 numbering is that there is one.</emphasis> It may seem pedantic to
868 emphasize this point but you'd be surprised at the number of
869 scripts and small programs that pop up without any version number
874 <emphasis>The second most important thing about a system of
875 numbering is that the numbers always go up.</emphasis> Automatic
876 version tracking systems and people's sense of order in the
877 universe will fall apart if version numbers don't rise. It doesn't
878 <emphasis>really</emphasis> matter if 2.1 is a big jump and
879 2.0.005 is a small jump but it does matter that 2.1 is more recent
884 Follow these two simple rules and you will not go (too)
885 wrong. Beyond this, the most common technique seems to be the
886 <quote>major level,</quote> <quote>minor level,</quote>
887 <quote>patch level</quote> version numbering scheme. Whether you
888 are familiar with the name or not, you interact with it all the
889 time. The first number is the major number and it signifies major
890 changes or rewrites. The second number is the minor number and it
891 represents added or tweaked functionality on top of a largely
892 coherant structure. The third number is the patch number and it
893 usually will only refer to releases fixing bugs.
897 The widespread use of this scheme is why I know the nature and
898 relative degree in the differences between a 2.4.12 release of the
899 Linux kernel and a 2.4.11, 2.2.12, and 1.2.12 without knowning
900 anything about any of the releases.
904 You can bend or break these rules, and people do. But beware, if
905 you choose to, someone will get annoyed, assume you don't know,
906 and try and educate you, probably not nicely. I always follow this
907 method and I implore you to do so as well.
911 There are several version numbering systems that are well known,
912 useful, and that might be worth looking into before you release
918 <term>Linux kernel version numbering:</term>
920 <para>The Linux kernel uses a versioning system where any odd
921 minor version number refers to an development or testing release
922 and any even minor version number refers to a stable
923 version. Think about it for a second. Under this system, 2.1 and
924 2.3 kernels were and always will be development or testing
925 kernels and 2.0, 2.2. and 2.4 kernels are all production code
926 with a higher degree of stability and more testing.
930 Whether you plan on having a split development model (as
931 described in <xref linkend="branches">) or only one version
932 released at a time, my experience with several free software
933 projects and with the Debian project has taught me that use of
934 Linux's version numbering system is worth taking into
935 consideration. In Debian, <emphasis>all</emphasis> minor
936 versions are stable distributions (2.0, 2.1, etc). However,
937 many people assume that 2.1 is an unstable or development
938 version and continue to use an older version until they get so
939 frustrated with the lack of development progress that they
940 complain and figure the system out. If you never release an odd
941 minor version but only release even ones, nobody is hurt, and
942 less people are confused. It's an idea worth taking into
949 <term>Wine version numbering:</term>
951 <para>Because of the unusual nature of wine's development where
952 the not-emulator is constantly improving but not working towards
953 any immediately achievable goal, wine is released every three
954 weeks. Wine does this by labeling their releases in <quote>Year
955 Month Day</quote> format where each release might be labeled
956 <quote>wine-XXXXXXXX</quote> where the version from January 04,
957 2000 would be <quote>wine-20000104</quote>. For certain
958 projects, <quote>Year Month Day</quote> format can make a lot of
965 <term>Mozilla milestones:</term>
967 <para>When one considers Netscape 6 and vendor versions, the
968 mozilla's project development structure is one of the most
969 complex free software models available. The project's version
970 numbering has reflected the unique situation in which it is
975 Mozilla's version numbering structure has historically been
976 made up of milestones. From the beginning of the mozilla
977 project, the goals of the project in the order and degree to
978 which they were to be achieved were charted out on a series of
979 <ulink url="http://www.mozilla.org/roadmap.html">road
980 maps</ulink>. Major points and achievements along these
981 road-maps were marked as milestones. Therefore, although
982 mozilla was built and distributed nightly as <quote>nightly
983 builds,</quote> on a day when the goals of a milestone on the
984 road-map had been reached, that particular build was marked as
985 a <quote>milestone release.</quote>
989 While I haven't seen this method employed in any other projects
990 to date, I like the idea and think that it might have value in
991 any testing or development branch of a large application under
1000 <!-- Section2: documentation-->
1002 <sect2 id="documentation">
1003 <title>Documentation</title>
1006 A huge number of otherwise fantastic free software applications
1007 have withered and died because their author was the only person
1008 who knew how to use them fully. Even if your program is written
1009 primarily for a techno-savvy group of users, documentation is
1010 helpful and even necessary for the survival of your project. You
1011 will learn later in <xref linkend="releasing"> that you should
1012 always release something that is usable. <emphasis>A piece of
1013 software without documentation is not usable.</emphasis>
1017 There are lots of different people you should document for and
1018 there are lots of ways to document your project. <emphasis>The
1019 importance of documentation in source code to help facilitate
1020 development by a large community is vital</emphasis> but it falls
1021 outside the scope of this HOWTO. This being the case, this section
1022 deals with useful tactics for user-directed documentation.
1026 A combination of tradition and necessity has resulted in a
1027 semi-regular system of documentation in most free software
1028 projects that is worth following. Both users and developers expect
1029 to be able to get documentation in several ways and it's essential
1030 that you provide the information they are seeking in a form they
1031 can read if your project is ever going to get off the
1032 ground. People have come to expect:
1036 <title>Man pages</title>
1038 <para>Your users will want to be able to type <quote>man
1039 yourprojectname</quote> end up with a nicely formatted man page
1040 highlighting the basic use of your application. Make sure that
1041 before you release your program, you've planned for this.
1045 Man pages are not difficult to write. There is excellent
1046 documentation on the man page writing process available through
1047 the <quote>The Linux Man-Page-HOWTO</quote> which is available
1048 through the Linux Documentation project <acronym>(LDP)</acronym>
1049 and is written by Jens Schweikhardt. It is available <ulink
1050 url="http://www.schweikhardt.net/man_page_howto.html">from
1051 Schweikhardt's site</ulink> or <ulink
1052 url="http://www.linuxdoc.org/HOWTO/mini/Man-Page.html">from the
1053 <acronym>LDP</acronym></ulink>.
1057 It is also possible to write man pages using DocBook
1058 SGML. Because man pages are so simple and the DocBook method
1059 relatively new, I have not been able to follow this up but would
1060 love help from anyone who can give me more information on how
1061 exactly how this is done.
1066 <title>Command line accessible documentation</title>
1069 Most users will expect some basic amount of documentation to be
1070 easily available from the command line. For few programs should
1071 this type of documentation extend for more than one screen (24 or
1072 25 lines) but it should cover the basic usage, a brief (one or
1073 two sentence) description of the program, a list of the commands
1074 with explanations, as well as all the major options (also with
1075 explanations), plus a pointer to more in-depth documentation for
1076 those who need it. The command line documentation for Debian's
1077 apt-get serves as an excellent example and a useful model:
1081 apt 0.3.19 for i386 compiled on May 12 2000 21:17:27
1082 Usage: apt-get [options] command
1083 apt-get [options] install pkg1 [pkg2 ...]
1085 apt-get is a simple command line interface for downloading and
1086 installing packages. The most frequently used commands are update
1090 update - Retrieve new lists of packages
1091 upgrade - Perform an upgrade
1092 install - Install new packages (pkg is libc6 not libc6.deb)
1093 remove - Remove packages
1094 source - Download source archives
1095 dist-upgrade - Distribution upgrade, see apt-get(8)
1096 dselect-upgrade - Follow dselect selections
1097 clean - Erase downloaded archive files
1098 autoclean - Erase old downloaded archive files
1099 check - Verify that there are no broken dependencies
1103 -q Loggable output - no progress indicator
1104 -qq No output except for errors
1105 -d Download only - do NOT install or unpack archives
1106 -s No-act. Perform ordering simulation
1107 -y Assume Yes to all queries and do not prompt
1108 -f Attempt to continue if the integrity check fails
1109 -m Attempt to continue if archives are unlocatable
1110 -u Show a list of upgraded packages as well
1111 -b Build the source package after fetching it
1112 -c=? Read this configuration file
1113 -o=? Set an arbitary configuration option, eg -o dir::cache=/tmp
1114 See the apt-get(8), sources.list(5) and apt.conf(5) manual
1115 pages for more information and options.
1119 It has become a GNU convention to make this type of information
1120 accessible with the <quote>-h</quote> and the
1121 <quote>--help</quote> options. Most GNU/Linux users will expect
1122 to be able to retrieve basic documentation these ways so if you
1123 choose to use different methods, be prepared for the flames and
1124 fallout that may result.
1129 <title>Files users will expect</title>
1131 In addition to man pages and command-line help, there are certain
1132 files where people will look for documentation, especially in any
1133 package containing source code. In a source distribution, most of
1134 these files can be stored in the root directory of the source
1135 distribution or in a subdirectory of the root called
1136 <quote>doc</quote> or <quote>Documentation.</quote> Common files
1137 in these places include:
1143 <term>README or Readme</term>
1146 <para>A document containing all the basic installation,
1147 compilation, and even basic use instructions that make up the
1148 bare minimum information needed to get the program up and
1149 running. A README is not your chance to be verbose but should
1150 be concise and effective. An ideal README is at least 30 lines
1151 long and more no more than 250.</para>
1156 <term>INSTALL or Install</term>
1159 <para>The INSTALL file should be much shorter than the README
1160 file and should quickly and concisely describe how to build
1161 and install the program. Usually an INSTALL file simply
1162 instructs the user to run <quote>./configure; make; make
1163 install</quote> and touches on any unusual options or actions
1164 that may be necessary. For most relatively standard install
1165 procedures and for most programs, INSTALL files are as short
1166 as possible and are rarely over 100 lines.</para>
1171 <term>CHANGELOG, Changelog, ChangeLog, or changelog</term>
1174 <para>A CHANGELOG is a simple file that every well-managed
1175 free software project should include. A CHANGELOG is simple
1176 the file that, as its name implies, logs or documents the
1177 changes you make to your program. The most simple way to
1178 maintain a CHANGELOG is to simply keep a file with the source
1179 code for your program and add a section to the top of the
1180 CHANGELOG with each release describing what has been changed,
1181 fixed, or added to the program. It's a good idea to post the
1182 CHANGELOG onto the website as well because it can help people
1183 decide whether they want or need to upgrade to a newer version
1184 or wait for a more significant improvement.</para>
1192 <para>A NEWS file and a ChangeLog are similar. Unlike a
1193 CHANGELOG, a NEWS file is not typically updated with new
1194 versions. Whenever new features are added, the developer
1195 responisble will make a note in the NEWS file. NEWS files
1196 should not have to be changed before a release (they should be
1197 kept up to date all along) but it's usually a good idea to
1198 check first anyway because often developers just forget to
1199 keep them as current as they should.</para>
1204 <term><acronym>FAQ</acronym></term>
1207 <para>For those of you that don't already know,
1208 <acronym>FAQ</acronym> stands for Frequently Asked Questions
1209 and a FAQ is a collection of exactly that. FAQs are not
1210 difficult to make. Simply make a policy that if you are asked
1211 a question or see a question on a mailing list two or more
1212 times, add the question (and its answer) to your FAQ. FAQs are
1213 more optional than the files listed above but they can save
1214 your time, increase usability, and decrease headaches on all
1224 <title>Website</title>
1226 It's only indirectly an issue of documentation but a good website
1227 is quickly becoming an essential part of any free software
1228 project. Your website should provide access to your documentation
1229 (in <acronym>HTML</acronym> if possible). It should also include
1230 a section for news and events around your program and a section
1231 that details the process of getting involved with development or
1232 testing and make an open invitation. It should also supply links
1233 to any mailing lists, similar websites, and provide a direct link
1234 to all the available ways of downloading your software.
1239 <title>Other documentation hints</title>
1242 All your documentation should be in plaintext, or, in cases where
1243 it is on your website primarily, in HTML. Everyone can cat a
1244 file, everyone has a pager, (almost) everyone can render
1245 HTML. <emphasis>You are welcome to distribute information in PDF,
1246 PostScript, RTF, or any number of other widely used formats but
1247 this information must also be available in plaintext or HTML or
1248 people will be very angry at you.</emphasis>
1252 It doesn't hurt to distribute any documentation for your program
1253 from your website (FAQs etc) with your program. Don't hesitate to
1254 throw any of this in the program's tarball. If people don't need
1255 it, they will delete it. I can repeat it over and over:
1256 <emphasis>Too much documentation is not a sin.</emphasis>
1261 <!-- Section2: presentation -->
1263 <sect2 id="presentation">
1264 <title>Other Presentation Issues</title>
1266 Many of the remaining issues surrounding the creation of a new
1267 free software program fall under what most people describe as
1268 common sense issues. Its often said that software engineering is
1269 90 percent common sense combined with 10 percent specialized
1270 knowledge. Still, they are worth noting briefly in hopes that they
1271 may remind a developer of something they may have forgotten.
1275 <title>Package formats</title>
1277 Package formats may differ depending on the system you are
1278 developing for. For windows based software, Zip archives (.zip)
1279 usually serve as the package format of choice. If you are
1280 developing for GNU/Linux, *BSD, or any UN*X, make sure that your
1281 source code is always available in tar'ed and gzip'ed format
1282 (.tar.gz). UNIX compress (.Z) has gone out of style and
1283 usefulness and faster computers have brought bzip2 (.bz2) into
1284 the spot-light as a more effective compression medium. I now make
1285 all my releases available in both gzip'ed and bzip2'ed tarballs.
1289 Binary packages should always be distribution specific. If you
1290 can build binary packages against a current version of a major
1291 distribution, you will only make your users happy. Try to foster
1292 relationships with users or developers of large distributions to
1293 develop a system for the consistent creation of binary
1294 packages. It's often a good idea to provide RedHat
1295 <acronym>RPM</acronym>'s (.rpm), Debian deb's (.deb) and source
1296 <acronym>RPM</acronym>'s <acronym>SRPM</acronym>'s if
1297 possible. Remember: <emphasis>While these binaries packages are
1298 nice, getting the source packaged and released should always be
1299 your priority. Your users or fellow developers can and will do
1300 the the binary packages for you.</emphasis>
1305 <title>Version control systems</title>
1308 A version control system can make a lot of these problems of
1309 packaging (and a lot of other problems mentioned in this HOWTO)
1310 less problematic. If you are using *NIX, CVS is your best bet. I
1311 recommend Karl Fogel's book on the subject (and the <ulink
1312 url="http://cvsbook.red-bean.com/">posted HTML version</ulink>)
1317 CVS or not, you should probably invest some time into learning
1318 about a version control system because it provides an automated
1319 way of solving many of the problems described by this HOWTO. I
1320 am not aware of any free version control systems for Windows or
1321 MacOS but I know that CVS clients exist for both
1322 platforms. Websites like <ulink
1323 url="http://sourceforge.net">SourceForge</ulink> do a great job
1324 as well with a nice, easy-to-use web interface to CVS.
1328 I'd love to devote more space in this HOWTO to CVS because I love
1329 it (I even use CVS to keep versions straight on this HOWTO!) but
1330 I think it falls outside the scope of this document and should have
1331 (already has) its own HOWTO.
1337 <title>Useful tidbits and presentation hints</title>
1340 Other useful hints include:
1348 <emphasis>Make sure that your program can always be found in a
1349 single location.</emphasis> Often this means that you have a
1350 single directory accessible via <acronym>FTP</acronym> or the
1351 web where the newest version can be quickly recognized. One
1352 effective technique is a provide a symlink called
1353 <quote>yourprojectname-latest</quote> that is always pointing
1354 to the most recent released or development version of your
1355 free software application. Keep in mind that this location
1356 will recieve many requests for downloads around releases so
1357 make sure that the server you choose has adequate bandwidth.
1363 <emphasis>Make sure that there is a consistent email address
1364 for bug reports.</emphasis> It's usually a good idea to make
1365 this something that is NOT your primary email address like
1366 yourprojectname@host or yourprojectname-bugs@host. This way,
1367 if you ever decide to hand over maintainership or if your
1368 email address changes, you simply need to change where this
1369 email address forwards. It also will allow for more than one
1370 person to deal with the influx of mail that is created if your
1371 project becomes as huge as you hope it will.

1385 <sect1 id="developers">
1386 <title>Maintaining a Project: Interacting with Developers</title>
1388 <primary>fswd!developers</primary>
1392 Once you have gotten your project started, you have overcome the
1393 most difficult hurdles in the development process of your
1394 program. Laying a firm foundation is essential, but the development
1395 process itself is equally important and provides just as many
1396 opportunities for failure. In the next two sections, I will
1397 describe running a project by discussing how to maintain a
1398 development effort through interactions with developers and with
1403 In releasing your program, your program becomes free software. This
1404 transition is more than just a larger user base. By releasing your
1405 program as free software, <emphasis>your</emphasis> software
1406 becomes the <emphasis>free software community's</emphasis>
1407 software. The direction of your software's development will be
1408 reshaped, redirected, and fully determined by your users and, to a
1409 larger extent, by other developers in the community.
1413 The major difference between free software development and
1414 propriety software development is the developer base. As the leader
1415 of a free software project, you need to attract and keep developers
1416 in a way that leaders of proprietary software projects simply don't
1417 have to worry about. <emphasis>As the person leading development of
1418 a free software project, you must harness the work of fellow
1419 developers by making responsible decisions and by responsibly
1420 choosing not to make decisions. You have to direct developers
1421 without being overbearing or bossy. You need to strive to earn
1422 respect and never forget to give it out.</emphasis>
1425 <!-- Section2: delegation -->
1427 <sect2 id="delegation">
1428 <title>Delegating Work</title>
1431 By now, you've hypothetically followed me through the early
1432 programming of a piece of software, the creation of a website and
1433 system of documentation, and we've gone ahead and (as will be
1434 discussed in <xref linkend="releasing">) released it to the rest
1435 of the world. Times passes, and if things go well, people become
1436 interested and want to help. The patches begin flowing in.
1440 <emphasis>Like the parent of any child who grows up, it's now time
1441 to wince, smile and do most difficult thing in any parents
1442 life: It's time to let go.</emphasis>
1446 Delegation is the political way of describing this process of
1447 <quote>letting go.</quote> It is the process of handing some of
1448 the responsibility and power over your project to other
1449 responsible and involved developers. It is difficult for anyone
1450 who has invested a large deal of time and energy into a project
1451 but it essential for the growth of any free software project. One
1452 person can only do so much. A free software project is nothing
1453 without the involvement of <emphasis>a group</emphasis> of
1454 developers. A group of developers can only be maintained through
1455 respectful and responsible leadership and delegation.
1459 As your project progresses, you will notice people who are putting
1460 significant amounts of time and effort into your project. These
1461 will be the people submitting the most patches, posting most on
1462 the mailing lists, and engaging in long email discussions. It is
1463 your responsibility to contact these people and to try and shift
1464 some of the power and responsibility of your position as the
1465 project's maintainer onto them (if they want it). There are
1466 several easy ways you can do this:
1470 In a bit of a disclaimer, delegation need not mean rule by
1471 comittee. In many cases it does and this has been proven to
1472 work. In other cases this has created problems. <ulink
1473 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
1474 Projects the Open Source Way</ulink> argues that <quote>OSS
1475 projects do best when one person is the clear leader of a team and
1476 makes the big decisions (design changes, release dates, and so
1477 on).</quote> I think this often true but would urge developers to
1478 consider the ideas that the project leader need not be the
1479 project's founder and that these important powers need not all rest
1480 with one person but that a release manager may be different than a
1481 lead developer. These situations are tricky politically so
1482 be careful and make sure it's necessary before you go around
1487 <title>How to delegate</title>
1490 You may find that other developers seem even more experienced or
1491 knowledgeable than you. Your job as a maintainer does not mean
1492 you have to be the best or the brightest. It means you
1493 are responsible for showing good judgment and for
1494 recognizing which solutions are maintainable and which are not.
1497 Like anything, its easier to watch others delegate than to do it
1498 yourself. In a sentence: <emphasis>Keep an eye out for other
1499 qualified developers who show an interest and sustained
1500 involvement with your project and try and shift responsibility
1501 towards them.</emphasis> The following ideas might be good places
1502 to start or good sources of inspiration:
1506 <title>Allow a larger group of people to have write access to your CVS
1507 repository and make real efforts towards rule by a

1514 members and all have write access to the main source
1515 repository. Their process is detailed <ulink
1516 url="http://httpd.apache.org/ABOUT_APACHE.html">online.</ulink>
1520 The <ulink url="http://www.debian.org/"> Debian Project</ulink>
1521 is an extreme example of rule by committee. At current count,
1522 more than 700 developers have full responsibility for
1523 aspects of the project. All these developers can upload into
1524 the main FTP server, and vote on major issues. Direction for
1525 the project is determined by the project's <ulink
1526 url="http://www.debian.org/social_contract">social
1527 contract</ulink> and a <ulink
1528 url="http://www.debian.org/devel/constitution">constitution</ulink>. To
1529 facilitate this system, there are special teams (i.e. the
1530 install team, the Japanese language team) as well as a technical
1531 committee and a project leader. The leader's main responsibility
1532 is to, <quote>appoint delegates or delegate decisions to the
1533 Technical Committee.</quote>
1537 While both of these projects operate on a scale that your
1538 project will not (at least initially), their example is
1539 helpful. Debian's idea of a project leader who can do
1540 <emphasis>nothing</emphasis> but delegate serves as a
1541 caricature of how a project can involve and empower a huge
1542 number of developers and grow to a huge size.
1547 <sect4 id="releasemanager">
1548 <title>Publicly appoint someone as the release manager for a
1549 specific release</title>
1552 A release manager is usually responsible for coordinating
1553 testing, enforcing a code freeze, being responsible for
1554 stability and quality control, packaging up the software, and
1555 placing it in the appropriate places to be downloaded.
1559 This use of the release manager is a good way to give yourself a
1560 break and to shift the responsibility for accepting and
1561 rejecting patches onto someone else. It is a good way of very
1562 clearly defining a chunk of work on the project as belonging to
1563 a certain person and its a great way of giving yourself room to

1569 <title>Delegate control of an entire branch</title>
1571 If your project chooses to have branches (as described in <xref
1572 linkend="branches">), it might be a good idea to appoint someone
1573 else to be the the head of a branch. If you like focusing your
1574 energy on development releases and the implementation of new
1575 features, hand total control over the stable releases to a
1576 well-suited developer.
1580 The author of Linux, Linus Torvalds, came out and crowned Alan
1581 Cox as <quote>the man for stable kernels.</quote> All patches
1582 for stable kernels go to Alan and, if Linus were to be taken
1583 away from work on Linux for any reason, Alan Cox would be more
1584 than suited to fill his role as the acknowledged heir to the
1585 Linux maintainership.

1594 <title>Accepting and Rejecting Patches</title>
1596 This HOWTO has already touched on the fact that as the maintainer
1597 of a free software project, one of your primary and most important
1598 responsibilities will be accepting and rejecting patches submitted
1599 to you by other developers.
1603 <title>Technical judgment</title>
1606 In <emphasis>Open Source Development with CVS</emphasis>, Karl
1607 Fogel makes a convincing argument that the most important things
1608 to keep in mind when rejecting or accepting patches are:
1615 <para>A firm knowledge of the scope of your program (that's the
1616 <quote>idea</quote> I talked about in <xref linkend="chooseproject">);</para>
1620 <para>The ability to recognize, facilitate, and direct
1621 <quote>evolution</quote> of your program so that the program
1622 can grow and change and incorporate functionality that was
1623 originally unforeseen;</para>
1627 <para>The necessity to avoid digressions that might expand the
1628 scope of the program too much and result and push the project
1629 towards an early death under its own weight and
1630 unwieldiness.</para>
1637 These are the criteria that you as a project maintainer should
1638 take into account each time you receive a patch.
1642 Fogel elaborates on this and states the <quote>the
1643 questions to ask yourself when considering whether to implement
1644 (or approve) a change are:</quote>
1651 <para>Will it benefit a significant percentage of the program's
1652 user community?</para>
1656 <para>Does it fit within the program's domain or within a
1657 natural, intuitive extension of that domain?</para>
1664 The answers to these questions are never straightforward and its
1665 very possible (and even likely) that the person who submitted the
1666 patch may feel differently about the answer to these questions
1667 than you do. However, if you feel that that the answer to either
1668 of those questions is <quote>no,</quote> it is your responsibility
1669 to reject the change. If you fail to do this, the project will
1670 become unwieldy and unmaintainable and many ultimately fail.
1675 <title>Rejecting patches</title>
1678 Rejecting patches is probably the most difficult and sensitive
1679 job that the maintainer of any free software project has to
1680 face. But sometimes it has to be done. I mentioned earlier (in
1681 <xref linkend="developers"> and in <xref linkend="delegation">)
1682 that you need to try and balance your responsibility and power to
1683 make what you think are the best technical decisions with the
1684 fact that you will lose support from other developers if you seem
1685 like you are on a power trip or being overly bossy or possessive
1686 of the community's project. I recommend that you keep these three
1687 major concepts in mind when rejecting patches (or other changes):
1691 <title>Bring it to the community</title>
1693 One of the best ways of justifying a decision to reject a patch
1694 and working to not seem like you keep an iron grip on your
1695 project is by not making the decision alone at all. It might
1696 make sense to turn over larger proposed changes or more
1697 difficult decisions to a development mailing list where they can
1698 be discussed and debated. There will be some patches (bug fixes,
1699 etc.) which will definitely be accepted and some that you feel
1700 are so offbase that they do not even merit further
1701 discussion. It is those that fall into the grey area between
1702 these two groups that might merit a quick forward to a mailing
1707 I recommend this process wholeheartedly. As the project
1708 maintainer you are worried about making the best decision for
1709 the project, for the project's users and developers, and for
1710 yourself as a responsible project leader. Turning things over to
1711 an email list will demonstrate your own responsibility and
1712 responsive leadership as it tests and serves the interests of
1713 your software's community.
1718 <title>Technical issues are not always good justification</title>
1720 Especially towards the beginning of your project's life, you
1721 will find that many changes are difficult to implement,
1722 introduce new bugs, or have other technical problems. Try to see
1723 past these. Especially with added functionality, good ideas do
1724 not always come from good programmers. Technical merit is a
1725 valid reason to postpone an application of a patch but it is not
1726 always a good reason to reject a change outright. Even small
1727 changes are worth the effort of working with the developer
1728 submitting the patch to iron out bugs and incorporate the change
1729 if you think it seems like a good addition to your project. The
1730 effort on your part will work to make your project a community
1731 project and it will pull a new or less experienced developer
1732 into your project and even teach them something that might help
1733 them in making their next patch.
1738 <title>Common courtesy</title>
1740 It should go without saying but, <emphasis>above all and in all
1741 cases, just be nice.</emphasis> If someone has an idea and cares
1742 about it enough to write some code and submit a patch, they
1743 care, they are motivated, and they are already involved. Your
1744 goal as the maintainer is make sure they submit again. They may
1745 have thrown you a dud this time but next time may be the idea or
1746 feature that revolutionizes your project.
1750 It is your responsibility to first justify your choice to not
1751 incorporate their change clearly and concisely. Then thank
1752 them. Let them know that you a appreciate their help and feel
1753 horrible that you can't incorporate their change. Let them know
1754 that you look forward to their staying involved and you hope
1755 that the next patch or idea meshes better with your project
1756 because you appreciate their work and want to see it in your
1757 application. If you have ever had a patch rejected after putting
1758 a large deal of time, thought, and energy into it, you remember
1759 how it feels and it feels bad. Keep this in mind when you have
1760 to let someone down. It's never easy but you need to do
1761 everything you can to make it as not-unpleasant as possible.
1767 <!-- Section2: branches -->
1769 <sect2 id="branches">
1770 <title>Stable and Development Branches</title>
1773 The idea of stable and development branches has already been
1774 described briefly in <xref linkend="chooseversioning"> and in
1775 <xref linkend="delegatebranch">. These allusions attest to some of
1776 the ways that multiple branches can affect your software. Branches
1777 can let you avoid (to some extent) some of the problems around
1778 rejecting patches (as described in <xref linkend="patching">) by
1779 allowing you to temporarily compromise the stability of your
1780 project without affecting those users who need that stability.
1784 The most common way of branching your project is to have one
1785 branch that is stable and one that is for development. This is the
1786 model followed by the Linux kernel that is described in <xref
1787 linkend="chooseversioning">. In this model, there is
1788 <emphasis>always</emphasis> one branch that is stable and always
1789 one that is in development. Before any new release, the
1790 development branch goes into a <quote>feature freeze</quote> as
1791 described in <xref linkend="freezing"> where major changes and
1792 added features are rejected or put on hold under the development
1793 kernel is released as the new stable branch and major development
1794 resumes on the development branch. Bug fixes and small changes
1795 that are unlikely to have any large negative repercussions are
1796 incorporated into the stable branch as well as the development
1801 Linux's model provides an extreme example. On many projects, there is no
1802 need to have two versions constantly available. It may make sense to
1803 have two versions only near a release. The Debian project has
1804 historically made both a stable and an unstable distribution
1805 available but has expanded to this to include: stable, unstable,
1806 testing, experimental, and (around release time) a frozen
1807 distribution that only incorporates bug fixes during the
1808 transition from unstable to stable. There are few projects whose
1809 size would necessitate a system like Debian's but this use of
1810 branches helps demonstrate how they can be used to balance
1811 consistent and effective development with the need to make regular
1812 and usable releases.
1816 In trying to set up a development tree for yourself, there are
1817 several things that might be useful to keep in mind:
1824 <term>Minimize the number of branches</term>
1826 <para>Debian may be able to make good use of four or five
1827 branches but it contains gigabytes of software in over 5000
1828 packages compiled for 5-6 different architectures. For you,
1829 two is probably a good ceiling. Too many branches will confuse
1830 your users (I can't count how many times I had to describe
1831 Debian's system when it only had 2 and sometimes 3 branches!),
1832 potential developers and even yourself. Branches can help but
1833 they come at a cost so use them very sparingly.</para>
1838 <term>Make sure that all your different branches are explained</term>
1840 <para>As I mentioned in the preceding paragraph, different
1841 branches <emphasis>will</emphasis> confuse your users. Do
1842 everything you can to avoid this by clearly explaining the
1843 different branches in a prominent page on your website and in a
1844 README file in the <acronym>FTP</acronym> or
1845 web directory.</para>
1848 I might also recommend against a mistake that I think Debian
1849 has made. The terms <quote>unstable,</quote>
1850 <quote>testing,</quote> and <quote>experimental</quote> are
1851 vague and difficult to rank in order of stability (or
1852 instability as the case may be). Try explaining to someone
1853 that <quote>stable</quote> actually means <quote>ultra
1854 stable</quote> and that <quote>unstable</quote> doesn't
1855 actually include any unstable software but is really stable
1856 software that is untested as a distribution.
1860 If you are going to use branches, especially early on, keep in
1861 mind that people are conditioned to understand the terms
1862 <quote>stable</quote> and <quote>development</quote> and you
1863 probably can't go wrong with this simple and common division of
1870 <term>Make sure all your branches are always available</term>
1872 <para>Like a lot of this document, this should probably should
1873 go without saying but experience has taught me that it's not
1874 always obvious to people. It's a good idea to physically split
1875 up different branches into different directories or directory
1876 trees on your <acronym>FTP</acronym> or web site. Linux
1877 accomplishes this by having kernels in a v2.2 and a v2.3
1878 subdirectory where it is immediately obvious (after you know
1879 their version numbering scheme) which directory is for the most
1880 recent stable and the current development releases. Debian
1881 accomplishes this by naming all their distribution with names
1882 (i.e. woody, potato, etc.) and then changing symlinks named
1883 <quote>stable,</quote> <quote>unstable</quote> and
1884 <quote>frozen</quote> to point to which ever distribution (by
1885 name) is in whatever stage. Both methods work and there are
1886 others. In any case, it is important that different branches
1887 are always available, are accessible from consistent locations,
1888 and that different branches are clearly distinguished from each
1889 other so your users know exactly what they want and where to
1899 <!-- Section2: otherdev -->

1902 <title>Other Project Management issues</title>
1904 There are more issues surrounding interaction with developers in a
1905 free software project that I can not touch on in great detail in a
1906 HOWTO of this size and scope. Please don't hesitate to contact me if you see
1907 any major omissions.
1911 Other smaller issues that are worth mentioning are:
1914 <sect3 id="freezing">
1915 <title>Freezing</title>
1917 For those projects that choose to adopt a split development model
1918 (<xref linkend="branches">), freezing is a concept that is worth
1919 becoming familiar with.
1923 Freezes come in two major forms. A <quote>feature freeze</quote>
1924 is a period when no significant functionality is added to a
1925 program. It is a period where established functionality (even
1926 skeletons of barely working functionality) can be improved and
1927 perfected. It is a period where bugs are fixed. This type of
1928 freeze is usually applied some period (a month or two) before a
1929 release. It is easy to push a release back as you wait for
1930 <quote>one more feature</quote> and a freeze helps to avoid this
1931 situation by drawing the much needed line in the sand. It gives
1932 developers room they need to get a program ready for release.
1936 The second type of freeze is a <quote>code freeze</quote> which
1937 is much more like a released piece of software. Once a piece of
1938 software has entered a <quote>code freeze,</quote> all changes to
1939 the code are discouraged and only changes that fix known bugs
1940 are permitted. This type of freeze usually follows a
1941 <quote>feature freeze</quote> and directly precedes a
1942 release. Most released software is in what could be interpreted
1943 as a sort of high level <quote>code freeze.</quote>
1947 Even if you never choose to appoint a release manager (<xref
1948 linkend="releasemanager">), you will have an easier time
1949 justifying the rejection or postponement of patches (<xref
1950 linkend="patching">) before a release with a publicly stated
1957 <title>Forks</title>
1959 I wasn't sure about how I would deal with forking in this
1960 document (or if I would deal with forking at all). A fork is when
1961 a group of developers takes code from a free software project and
1962 actually starts a brand new free software project with it. The
1963 most famous example of a fork was between Emacs and XEmacs. Both
1964 emacsen are based on an identical code-base but for technical,
1965 political, and philosophical reasons, development was split into
1966 two projects which now compete with each other.
1970 The short version of the fork section is, <emphasis>don't do
1971 them.</emphasis> Forks force developers to choose one project to
1972 work with, cause nasty political divisions, and redundancy of
1973 work. Luckily, usually the threat of the fork is enough to scare
1974 the maintainer or maintainers of a project into changing the way
1975 they run their project.
1979 In his chapter on <quote>The Open Source Process,</quote> Karl
1980 Fogel describes how to do a fork if you absolutely must. If you
1981 have determined that is absolutely necessary and that the
1982 differences between you and the people threatening to fork are
1983 absolutely unresolvable, I recommend Fogel's book as a good place

1992 <title>Maintaining a Project: Interacting with Users</title>
1994 <primary>fswd!users</primary>
1998 If you've worked your way up to here, congratulations, you are
1999 nearing the end of this document. This final section describes some
2000 of the situations in which you, in your capacity as project
2001 maintainer, will be interacting with users. It gives some
2002 suggestions on how these situations might be handled effectively.
2006 Interacting with users is difficult. In our discussion of
2007 interaction with developers, the underlying assumption is that in a
2008 free software project, a project maintainer must constantly strive to
2009 attract and keep developers who can easily leave at any time.
2013 Users in the free software community are different than developers
2014 and are also different than users in the world of proprietary
2015 software and they should be treated differently than either
2016 group. Some ways in which the groups differ significantly follow:
2023 <para>The lines between users and developers are blurred in ways
2024 that is totally foreign to any proprietary development
2025 model. Your users are often your developers and vice
2030 <para>In the free software world, you are often your users' only
2031 choice. Because there is such an emphasis on not replicating the
2032 work of others in the free software community and because the
2033 element of competition present in the propriety software model is
2034 absent (or at least in an extremely different form) in the free
2035 software development model, you will probably be the only project
2036 that does what you do (or at least the only one that does what
2037 you do in the way that you do it). This means your responsiveness
2038 to your users is even more important than in the proprietary
2039 software world.</para>
2043 <para>In an almost paradoxical situation, free software projects
2044 have less immediate or dire consequences for ignoring their users
2045 altogether. It is also often easier to do. Because you don't
2046 usually need to compete with another product, chances are good
2047 that you will not be scrambling to gain the features of your
2048 competitor's newest program. This means that your development
2049 process will have to be directed either internally, by a
2050 commitment to your users, or through both.</para>
2056 Trying to tackle this unique situation can only be done
2057 indirectly. Developers and maintainers need to listen to users and
2058 to try and be as responsive as possible. A solid knowledge of the
2059 situation recounted above is any free software developer's best tool
2060 for shifting his development or leadership style to fit the unique
2061 process of free software project management. This chapters will try and
2062 introduce some of the more difficult or important points in any
2063 projects interactions with users and give some hints on how to

2069 <sect2 id="testing">
2070 <title>Testing and Testers</title>
2073 In addition to your users being your developers, they are also
2074 (and perhaps more commonly) your testers. Before I get flamed, I
2075 should rephrase my sentence: <emphasis>some of your
2076 users</emphasis> (those who explicityly volunteer) are your
2081 It is important that this distinction be made early on because not
2082 all of your users want to be testers. Many users want to use
2083 stable software and don't care if they don't have the newest,
2084 greatest software with the latest, greatest features. These users
2085 except a stable, tested piece of software without major or obvious
2086 bugs and will be angry if they find themselves testing. This is
2087 yet another way in which a split development model (as mentioned
2088 in <xref linkend="branches">) might come in handy.

2136 <term>Standards conformance</term>
2139 <para>If possible, make sure your programs conforms to
2140 standards. If it's interactive, don't be too creative with
2141 interfaces. If it is non-interactive, make sure it communicates
2142 over appropriate and established channels with other programs
2143 and with the rest of the system.</para>
2150 <title>Automated testing</title>
2152 For many programs, many common mistakes can be caught by
2153 automated means. Automated tests tend to be pretty good at
2154 catching errors that you've run into several times before or
2155 the things you just forget. They are not very good at finding
2156 errors, even major ones, that are totally unforeseen.
2160 CVS comes with a bourne shell script called sanity.sh that is
2161 worth looking at. Debian uses a program called lintian that
2162 checks Debian packages for all of the most common errors. While
2163 use of these scripts may not be helpful, there is a host of other
2164 sanity checking software on the net that may be applicable (feel
2165 free to email me any recommendations). None of these will create
2166 a bug-free release but they will avoid at least some major
2167 oversights. Finally, if your programs become a long term
2168 endeavor, you will find that there are certain errors that you
2169 tend to make over and over. Start a collection of scripts that
2170 check for these errors to help keep them out of future releases.
2175 <title>Testing by testers</title>
2177 For any program that depends on user interactivity, many bugs
2178 will only be uncovered through testing by users actually clicking
2179 the keys and pressing the mouse buttons. For this you need
2180 testers and as many as possible.
2184 The most difficult part of testing is finding testers. It's
2185 usually a good tactic to post a message to a relevant mailing
2186 list or news group announcing a specific proposed release date
2187 and outlining the functionality of your program. If you put some
2188 time into the announcement, you are sure to get a few responses.
2192 The second most difficult part of testing is
2193 <emphasis>keeping</emphasis> your testers and keeping them
2194 actively involved in the testing process. Fortunately, there are
2195 some tried and true tactics that can applied towards this end:
2202 <term>Make things simple for your testers</term>
2204 <para>Your testers are doing you a favor so make it as easy as
2205 possible for them. This means that you should be careful to
2206 package your software in a way that is easy to find, unpack,
2207 install, and uninstall. This also means you should explain
2208 what you are looking for to each tester and make the means for
2209 reporting bugs simple and well established. The key is to
2210 provide as much structure as possible to make your testers'
2211 jobs easy and to maintain as much flexibility as possible for
2212 those that want to do things a little differently.</para>
2217 <term>Be responsive to your testers</term>
2219 <para>When your testers submit bugs, respond to them and
2220 respond quickly. Even if you are only responding to tell them
2221 that the bug has already been fixed, quick and consistent
2222 responses make them feel like their work is heard, important,
2223 and appreciated.</para>

2249 <title>Setting up Support Infrastructure</title>
2252 While testing is important, the large part of your interactions
2253 and responsibility to your users falls under the category of
2254 support. The best way to make sure your users are adequately
2255 supported in using your program is to set up a good infrastructure
2256 for this purpose so that your developers and users help each other
2257 and less of the burden falls on you. This way, people will also
2258 get quicker and better responses to their questions. This
2259 infrastructure comes in several major forms:
2263 <title>Documentation</title>
2265 It should not come as any surprise that the key element to any
2266 support infrastructure is good documentation. This topic was
2267 largely covered in <xref linkend="documentation"> and will not be
2273 <title>Mailing lists</title>
2275 Aside from documentation, effective mailing lists will be your
2276 greatest tool in providing user support. Running a mailing list
2277 well is more complicated than installing mailing list software
2282 <title>Separate lists</title>
2285 A good idea is too separate your user and development mailing
2286 lists (perhaps into project-user@host and project-devel@host)
2287 and enforce the division. If people post a development question
2288 onto -user, politely ask them to repost it onto -devel and vise
2289 versa. Subscribe yourself to both groups and encourage all
2290 primarily developers to do the same.
2294 This system provides so that no one person is stuck doing all of
2295 the support work and works so that users learn more about the
2296 program, they can help newer users with their questions.
2301 <title>Choose mailing list software well</title>
2303 Please don't make the selection of mailing list software
2304 impulsively. Please consider easy accessibility by users without
2305 a lot of technical experience so you want to be as easy as
2306 possible. Web accessibility to an archive of the list is also
2311 The two biggest free software mailing list programs are <ulink
2312 url="http://www.greatcircle.com/majordomo/">majordomo</ulink>
2313 and <ulink url="http://www.list.org/">GNU Mailman</ulink>. A
2314 long time advocate of majordomo, I would now recommend any
2315 project choose GNU Mailman. It fulfills the criteria listed
2316 above and makes it easier. It provides a good mailing
2317 list program for a free software project maintainer as opposed
2318 to a good mailing list application for a mailing list
2323 There are other things you want to take into consideration in
2324 setting up your list. If it is possible to gate your mailing
2325 lists to USENET and provide it in digest form as well as
2326 making them accessible on the web, you will please some users
2327 and work to make the support infrastructure slightly more
2334 <title>Other support ideas</title>
2337 A mailing list and accessible documentation are far from all you
2338 can do to set up good user support infrastructure. Be
2339 creative. If you stumble across something that works well, email me
2340 and I'll include it here.
2344 <title>Make your self accessible</title>
2346 You can not list too few methods to reach you. If you hang out
2347 in an <acronym>IRC</acronym> channel, don't hesitate to list it
2348 in your projects documentation. List email and snailmail
2349 addresses, and ways to reach you via <acronym>ICQ</acronym>,
2350 <acronym>AIM</acronym>, or Jabber if they apply.
2355 <title>Bug management software</title>
2357 For many large software projects, use of bug management software
2358 is essential to keep track of which bugs have been fixed, which
2359 bugs have not been fixed, and which bugs are being fixed by
2360 which people. Debian uses the <ulink
2361 url="http://bugs.debian.org">Debian Bug Tracking System</ulink>
2362 (<acronym>BTS</acronym>) although it may not be best choice for
2363 every project (it seems to currently be buckling under its own
2364 weight) As well as a damn good web browser, the mozilla project
2365 has spawned a sub-project resulting in a bug tracking system
2367 url="http://www.mozilla.org/projects/bugzilla/">bugzilla</ulink>
2368 which has become extremely possible and which I like a lot.
2372 These systems (and others like them) can be unwieldy so
2373 developers should be careful to not spend more time on the bug
2374 tracking system than on the bugs or the projects themselves. If
2375 a project continues to grow, use of a bug tracking system can
2376 provide an easy standard avenue for users and testers to report
2377 bugs and for developers and maintainers to fix them and track
2378 them in an orderly fashion.
2384 <!-- Section2: releasing -->
2386 <sect2 id="releasing">
2387 <title>Releasing Your Program</title>
2390 As mentioned earlier in the HOWTO, the first rule of releasing is,
2391 <emphasis>release something useful.</emphasis> Non-working or
2392 not-useful software will not attract anyone to your
2393 project. People will be turned off of your project and will be likely
2394 to simply gloss over it next time they see a new version
2395 announced. Half-working software, if useful, will intrigue people,
2396 whet their appetites for versions to come, and encourage them to
2397 join the development process.
2401 <title>When to release</title>
2404 Making the decision to release your software for the first time
2405 is an incredibly important and incredibly stressful decision. But
2406 it needs to done. My advice is to try and make something that
2407 is complete enough to be usable and incomplete enough to allow
2408 for flexibility and room for imagination by your future
2409 developers. It's not an easy decision. Ask for help on a local
2410 Linux User Group mailing list or from a group of developer
2415 One tactic is to first do an <quote>alpha</quote> or
2416 <quote>beta</quote> release as described below in <xref
2417 linkend="alphabeta">. However, most of the guidelines described
2422 <emphasis>When you feel in your gut that it is time and you feel
2423 you've weighed the situation well several times, cross your
2424 fingers and take the plunge.</emphasis>
2428 After you've released for the first time, knowing when to release
2429 becomes less stressful, but just as difficult to gauge. I like
2430 the criteria offered by Robert Krawitz in his article, <ulink
2431 url="http://www.advogato.org/article/196.html"><quote>Free
2432 Software Project Management</quote></ulink> for maintaining a
2433 good release cycle. He recommends that you ask yourself,
2434 <quote>does this release...</quote>
2440 <para>Contain sufficient new functionality or bug fixes to be
2441 worth the effort.</para>
2445 <para>Be spaced sufficiently far apart to allow the user time
2446 to work with the latest release.</para>
2450 <para>Be sufficiently functional so that the user can get work
2451 done (quality).</para>
2457 If the answer is yes to all of these questions, its probably time
2458 for a release. If in doubt, remember that asking for advice can't
2464 <title>How to release</title>
2467 If you've followed the guidelines described in this HOWTO up
2468 until this point, the mechanics of doing a release are going to
2469 be the easy part of releasing. If you have set up consistent
2470 distribution locations and the other infrastructure described in
2471 the preceding sections, releasing should be as simple as building
2472 the package, checking it once over, and uploading it into the
2473 appropriate place and then making your website reflect the
2478 <sect3 id="alphabeta">
2479 <title>Alpha, beta, and development releases</title>
2482 When contemplating releases, it worth considering the fact that
2483 not every release needs to be a full numbered release. Software
2484 users are accustomed to pre-releases but you must be careful to
2485 label these releases accurately or they will cause more problems then
2490 The observation is often made that many free software developers
2491 seem to be confused about the release cycle. <quote><ulink
2492 url="http://news.linuxprogramming.com/news_story.php3?ltsn=2000-10-31-001-05-CD">Managing
2493 Projects the Open Source Way</ulink></quote> suggests that you memorize
2494 the phrase, <quote>Alpha is not Beta. Beta is not Release</quote>
2495 and I'd agree that tis is a probably a good idea.
2502 <term>alpha releases</term>
2504 <para>Alpha software is feature-complete but sometimes only
2505 partially functional.</para>
2507 <para>Alpha releases are expected to be unstable, perhaps a
2508 little unsafe, but definitely usable. They
2509 <emphasis>can</emphasis> have known bugs and kinks that have
2510 yet to be worked out. Before releasing an alpha, be sure to
2511 keep in mind that <emphasis>alpha releases are still
2512 releases</emphasis> and people are not going to be expecting a
2513 nightly build from the CVS source. An alpha should work and
2514 have minimal testing and bug fixing already finished.</para>
2519 <term>beta releases</term>
2521 <para>Beta software is feature-complete and functional, but is
2522 in the testing cycle and still has a few bugs left to be
2525 <para>Beta releases are general expected to be usable and
2526 slightly unstable, although definitely <emphasis>not
2527 unsafe.</emphasis> Beta releases usually preclude a full
2528 release by under a month. They can contain small known bugs
2529 but no major ones. All major functionality should be fully
2530 implemented although the exact mechanics can still be worked
2531 out. Beta releases are great tool to whet the appetites of
2532 potential users by giving them a very realistic view of where
2533 your project is going to be in the very near future and can
2534 help keep interest by giving people
2535 <emphasis>something.</emphasis></para>
2540 <term>development releases</term>
2542 <para><quote>Development release</quote> is much a more vague
2543 term than <quote>alpha</quote> or <quote>beta</quote>. I
2544 usually choose to reserve the term for discussion of a
2545 development branch although there are other ways to use the
2546 term. So many in fact, that I feel the term has been
2547 cheapened. The popular window manager <ulink
2548 url="http://www.enlightenment.org">Enlightenment</ulink> has
2549 released <emphasis>nothing but</emphasis> development
2550 releases. Most often, the term is used to describe releases
2551 that are not even alpha or beta and if I were to release a
2552 pre-alpha version of a piece of software in order to keep
2553 interest in my project alive, this is probably how I would
2554 have to label it.</para>
2564 <!-- Section2: announcing -->
2566 <sect2 id="announcing">
2567 <title>Announcing Your Project</title>
2570 Well, you've done it. You've (at least for the purposes of this
2571 HOWTO) designed, built, and released your free software
2572 project. All that is left is for you to tell the world so they
2573 know to come and try it out and hopefully jump on board with
2574 development. If everything is in order as described above, this
2575 will be a quick and painless process. A quick announcement is all
2576 that it takes to put yourself on the free software community's
2581 <title>Mailing lists and USENET</title>
2583 Email is still the way that most people on the Internet get their
2584 information. Its a good idea to send a message announcing your
2585 program to any relevant mailing list you know of and any relevant
2586 USENET discussion group. Karl Fogel recommends that use you
2587 simple subject describing the fact that the message is an
2588 announcement, the name of the program, the version, and a
2589 half-line long description of its functionality. This way, any
2590 interested user or developer will be immediately attracted to
2591 your announcement. Fogel's example looks like:
2594 <screen>Subject: ANN: aub 1.0, a program to assemble USENET binaries</screen>
2597 The rest of the email should describe the programs functionality
2598 quickly and concisely in no more than two paragraphs and should
2599 provide links to the projects webpage and direct links to
2600 downloads for those that want to try it right away.
2604 You should repeat this announcement process consistently in the
2605 same locations for each subsequent release.
2610 <title>freshmeat.net</title>
2612 Mentioned earlier in <xref linkend="evalwhere">, in today's free
2613 software community, announcements of your project on freshmeat
2614 are almost more important than announcements on mailing lists.

2622 database. In addition to a large website, freshmeat provides a
2623 daily newsletter that highlights all the days releases and
2624 reaches a huge audience (I personally skim it every night for any
2625 interesting new releases).

2828 I have spent a huge amount of time on advogato and I've gone

3100 <title>0. PREAMBLE</title>
3102 The purpose of this License is to make a manual, textbook, or
3103 other written document <quote>free</quote> in the sense of
3104 freedom: to assure everyone the effective freedom to copy and
3105 redistribute it, with or without modifying it, either
3106 commercially or noncommercially. Secondarily, this License
3107 preserves for the author and publisher a way to get credit for
3108 their work, while not being considered responsible for
3109 modifications made by others.
3113 This License is a kind of <quote>copyleft</quote>, which means
3114 that derivative works of the document must themselves be free in
3115 the same sense. It complements the GNU General Public License,
3116 which is a copyleft license designed for free software.
3120 We have designed this License in order to use it for manuals for
3121 free software, because free software needs free documentation: a
3122 free program should come with manuals providing the same
3123 freedoms that the software does. But this License is not limited
3124 to software manuals; it can be used for any textual work,
3125 regardless of subject matter or whether it is published as a
3126 printed book. We recommend this License principally for works
3127 whose purpose is instruction or reference.

3133 This License applies to any manual or other work that contains a
3134 notice placed by the copyright holder saying it can be
3135 distributed under the terms of this License. The
3136 <quote>Document</quote>, below, refers to any such manual or
3137 work. Any member of the public is a licensee, and is addressed
3138 as <quote>you</quote>.

3149 A <quote>Secondary Section</quote> is a named appendix or a
3150 front-matter section of the <link

3152 with the relationship of the publishers or authors of the
3153 Document to the Document's overall subject (or to related
3154 matters) and contains nothing that could fall directly within
3155 that overall subject. (For example, if the Document is in part a
3156 textbook of mathematics, a Secondary Section may not explain any
3157 mathematics.) The relationship could be a matter of historical
3158 connection with the subject or with related matters, or of
3159 legal, commercial, philosophical, ethical or political position

3181 A <quote>Transparent</quote> copy of the <link

3185 directly and straightforwardly with generic text editors or (for
3186 images composed of pixels) generic paint programs or (for
3187 drawings) some widely available drawing editor, and that is
3188 suitable for input to text formatters or for automatic
3189 translation to a variety of formats suitable for input to text

3192 subsequent modification by readers is not Transparent. A copy
3193 that is not <quote>Transparent</quote> is called
3194 <quote>Opaque</quote>.
3198 Examples of suitable formats for Transparent copies include

3227 copyright notices, and the license notice saying this License
3228 applies to the Document are reproduced in all copies, and that
3229 you add no other conditions whatsoever to those of this
3230 License. You may not use technical measures to obstruct or
3231 control the reading or further copying of the copies you make or
3232 distribute. However, you may accept compensation in exchange for
3233 copies. If you distribute a large enough number of copies you
3234 must also follow the conditions in <link

3249 and the Document's license notice requires <link

3251 the copies in covers that carry, clearly and legibly, all these

3253 Back-Cover Texts on the back cover. Both covers must also
3254 clearly and legibly identify you as the publisher of these
3255 copies. The front cover must present the full title with all
3256 words of the title equally prominent and visible. You may add
3257 other material on the covers in addition. Copying with changes
3258 limited to the covers, as long as they preserve the title of the
3259 <link linkend="fdl-document">Document</link> and satisfy these
3260 conditions, can be treated as verbatim copying in other

3280 material, which the general network-using public has access to
3281 download anonymously at no charge using public-standard network
3282 protocols. If you use the latter option, you must take
3283 reasonably prudent steps, when you begin distribution of Opaque
3284 copies in quantity, to ensure that this Transparent copy will
3285 remain thus accessible at the stated location until at least one
