27.1 Timeline
=============

1994-09-19 First CVS commit.
     If we can trust the CVS repository, David J. MacKenzie (djm)
     started working on Automake (or AutoMake, as it was spelt then)
     this Monday.

     The first version of the `automake' script looks as follows.

          #!/bin/sh

          status=0

          for makefile
          do
            if test ! -f ${makefile}.am; then
              echo "automake: ${makefile}.am: No such honkin' file"
              status=1
              continue
            fi

            exec 4> ${makefile}.in

          done

     From this you can already see that Automake will be about reading
     `*.am' file and producing `*.in' files.  You cannot see anything
     else, but if you also know that David is the one who created
     Autoconf two years before you can guess the rest.

     Several commits follow, and by the end of the day Automake is
     reported to work for GNU fileutils and GNU m4.

     The modus operandi is the one that is still used today: variables
     assignments in `Makefile.am' files trigger injections of precanned
     `Makefile' fragments into the generated `Makefile.in'.  The use of
     `Makefile' fragments was inspired by the 4.4BSD `make' and include
     files, however Automake aims to be portable and to conform to the
     GNU standards for `Makefile' variables and targets.

     At this point, the most recent release of Autoconf is version 1.11,
     and David is preparing to release Autoconf 2.0 in late October.
     As a matter of fact, he will barely touch Automake after September.

1994-11-05 David MacKenzie's last commit.
     At this point Automake is a 200 line portable shell script, plus
     332 lines of `Makefile' fragments.  In the `README', David states
     his ambivalence between "portable shell" and "more appropriate
     language":

          I wrote it keeping in mind the possibility of it becoming an
          Autoconf macro, so it would run at configure-time.  That
          would slow configuration down a bit, but allow users to
          modify the Makefile.am without needing to fetch the AutoMake
          package.  And, the Makefile.in files wouldn't need to be
          distributed.  But all of AutoMake would.  So I might
          reimplement AutoMake in Perl, m4, or some other more
          appropriate language.

     Automake is described as "an experimental Makefile generator".
     There is no documentation.  Adventurous users are referred to the
     examples and patches needed to use Automake with GNU m4 1.3,
     fileutils 3.9, time 1.6, and development versions of find and
     indent.

     These examples seem to have been lost.  However at the time of
     writing (10 years later in September, 2004) the FSF still
     distributes a package that uses this version of Automake: check
     out GNU termutils 2.0.

1995-11-12 Tom Tromey's first commit.
     After one year of inactivity, Tom Tromey takes over the package.
     Tom was working on GNU cpio back then, and doing this just for fun,
     having trouble finding a project to contribute to.  So while
     hacking he wanted to bring the `Makefile.in' up to GNU standards.
     This was hard, and one day he saw Automake on
     `ftp://alpha.gnu.org/', grabbed it and tried it out.

     Tom didn't talk to djm about it until later, just to make sure he
     didn't mind if he made a release.  He did a bunch of early
     releases to the Gnits folks.

     Gnits was (and still is) totally informal, just a few GNU friends
     who Franc,ois Pinard knew, who were all interested in making a
     common infrastructure for GNU projects, and shared a similar
     outlook on how to do it.  So they were able to make some progress.
     It came along with Autoconf and extensions thereof, and then
     Automake from David and Tom (who were both gnitsians).  One of
     their ideas was to write a document paralleling the GNU standards,
     that was more strict in some ways and more detailed.  They never
     finished the GNITS standards, but the ideas mostly made their way
     into Automake.

1995-11-23 Automake 0.20
     Besides introducing automatic dependency tracking (*note
     Dependency Tracking Evolution::), this version also supplies a
     9-page manual.

     At this time `aclocal' and `AM_INIT_AUTOMAKE' did not exist, so
     many things had to be done by hand.  For instance, here is what a
     configure.in (this is the former name of the `configure.ac' we use
     today) must contain in order to use Automake 0.20:

          PACKAGE=cpio
          VERSION=2.3.911
          AC_DEFINE_UNQUOTED(PACKAGE, "$PACKAGE")
          AC_DEFINE_UNQUOTED(VERSION, "$VERSION")
          AC_SUBST(PACKAGE)
          AC_SUBST(VERSION)
          AC_ARG_PROGRAM
          AC_PROG_INSTALL

     (Today all of the above is achieved by `AC_INIT' and
     `AM_INIT_AUTOMAKE'.)

     Here is how programs are specified in `Makefile.am':

          PROGRAMS = hello
          hello_SOURCES = hello.c

     This looks pretty much like what we do today, except the
     `PROGRAMS' variable has no directory prefix specifying where
     `hello' should be installed: all programs are installed in
     `$(bindir)'.  `LIBPROGRAMS' can be used to specify programs that
     must be built but not installed (it is called `noinst_PROGRAMS'
     nowadays).

     Programs can be built conditionally using `AC_SUBST'itutions:

          PROGRAMS = @progs@
          AM_PROGRAMS = foo bar baz

     (`AM_PROGRAMS' has since then been renamed to `EXTRA_PROGRAMS'.)

     Similarly scripts, static libraries, and data can built and
     installed using the `LIBRARIES', `SCRIPTS', and `DATA' variables.
     However `LIBRARIES' were treated a bit specially in that Automake
     did automatically supply the `lib' and `.a' prefixes.  Therefore
     to build `libcpio.a', one had to write

          LIBRARIES = cpio
          cpio_SOURCES = ...

     Extra files to distribute must be listed in `DIST_OTHER' (the
     ancestor of `EXTRA_DIST').  Also extra directories that are to be
     distributed should appear in `DIST_SUBDIRS', but the manual
     describes this as a temporary ugly hack (today extra directories
     should also be listed in `EXTRA_DIST', and `DIST_SUBDIRS' is used
     for another purpose, *note Conditional Subdirectories::).

1995-11-26 Automake 0.21
     In less time that it takes to cook a frozen pizza, Tom rewrites
     Automake using Perl.  At this time Perl 5 is only one year old, and
     Perl 4.036 is in use at many sites.  Supporting several Perl
     versions has been a source of problems through the whole history
     of Automake.

     If you never used Perl 4, imagine Perl 5 without objects, without
     `my' variables (only dynamically scoped `local' variables),
     without function prototypes, with function calls that needs to be
     prefixed with `&', etc.  Traces of this old style can still be
     found in today's `automake'.

1995-11-28 Automake 0.22
1995-11-29 Automake 0.23
     Bug fixes.

1995-12-08 Automake 0.24
1995-12-10 Automake 0.25
     Releases are raining.  0.24 introduces the uniform naming scheme we
     use today, i.e., `bin_PROGRAMS' instead of `PROGRAMS',
     `noinst_LIBRARIES' instead of `LIBLIBRARIES', etc.  (However
     `EXTRA_PROGRAMS' does not exist yet, `AM_PROGRAMS' is still in
     use; and `TEXINFOS' and `MANS' still have no directory prefixes.)
     Adding support for prefixes like that was one of the major ideas
     in automake; it has lasted pretty well.

     AutoMake is renamed to Automake (Tom seems to recall it was
     Franc,ois Pinard's doing).

     0.25 fixes a Perl 4 portability bug.

1995-12-18 Jim Meyering starts using Automake in GNU Textutils.

1995-12-31 Franc,ois Pinard starts using Automake in GNU tar.

1996-01-03 Automake 0.26
1996-01-03 Automake 0.27
     Of the many change and suggestions sent by Franc,ois Pinard and
     included in 0.26, the most important is perhaps the advise that to
     ease customization a user rule or variable definition should always
     override an Automake rule or definition.

     Gordon Matzigkeit and Jim Meyering are two other early contributors
     that have been sending fixes.

     0.27 fixes yet another Perl 4 portability bug.

1996-01-13 Automake 0.28
     Automake starts scanning `configure.in' for `LIBOBJS' support.
     This is an important step because until this version Automake did
     only know about the `Makefile.am's it processed.  `configure.in'
     was Autoconf's world and the link between Autoconf and Automake
     had to be done by the `Makefile.am' author.  For instance, if
     `config.h' was generated by `configure', it was the package
     maintainer's responsibility to define the `CONFIG_HEADER' variable
     in each `Makefile.am'.

     Succeeding releases will rely more and more on scanning
     `configure.in' to better automate the Autoconf integration.

     0.28 also introduces the `AUTOMAKE_OPTIONS' variable and the
     `--gnu' and `--gnits' options, the latter being stricter.

1996-02-07 Automake 0.29
     Thanks to `configure.in' scanning, `CONFIG_HEADER' is gone, and
     rebuild rules for `configure'-generated file are automatically
     output.

     `TEXINFOS' and `MANS' converted to the uniform naming scheme.

1996-02-24 Automake 0.30
     The test suite is born.  It contains 9 tests.  From now on test
     cases will be added pretty regularly (*note Releases::), and this
     proved to be really helpful later on.

     `EXTRA_PROGRAMS' finally replaces `AM_PROGRAMS'.

     All the third-party Autoconf macros, written mostly by Franc,ois
     Pinard (and later Jim Meyering), are distributed in Automake's
     hand-written `aclocal.m4' file.  Package maintainers are expected
     to extract the necessary macros from this file.  (In previous
     version you had to copy and paste them from the manual...)

1996-03-11 Automake 0.31
     The test suite in 0.30 was run via a long `check-local' rule.  Upon
     Ulrich Drepper's suggestion, 0.31 makes it an Automake rule output
     whenever the `TESTS' variable is defined.

     `DIST_OTHER' is renamed to `EXTRA_DIST', and the `check_' prefix
     is introduced.  The syntax is now the same as today.

1996-03-15 Gordon Matzigkeit starts writing libtool.

1996-04-27 Automake 0.32
     `-hook' targets are introduced; an idea from Dieter Baron.

     `*.info' files, which were output in the build directory are now
     built in the source directory, because they are distributed.  It
     seems these files like to move back and forth as that will happen
     again in future versions.

1996-05-18 Automake 0.33
     Gord Matzigkeit's main two contributions:

        * very preliminary libtool support

        * the distcheck rule

     Although they were very basic at this point, these are probably
     among the top features for Automake today.

     Jim Meyering also provides the infamous `jm_MAINTAINER_MODE',
     since then renamed to `AM_MAINTAINER_MODE' and abandoned by its
     author (*note maintainer-mode::).

1996-05-28 Automake 1.0
     After only six months of heavy development, the automake script is
     3134 lines long, plus 973 lines of `Makefile' fragments.  The
     package has 30 pages of documentation, and 38 test cases.
     `aclocal.m4' contains 4 macros.

     From now on and until version 1.4, new releases will occur at a
     rate of about one a year.  1.1 did not exist, actually 1.1b to
     1.1p have been the name of beta releases for 1.2.  This is the
     first time Automake uses suffix letters to designate beta
     releases, an habit that lasts.

1996-10-10 Kevin Dalley packages Automake 1.0 for Debian GNU/Linux.

1996-11-26 David J. MacKenzie releases Autoconf 2.12.
     Between June and October, the Autoconf development is almost
     staled.  Roland McGrath has been working at the beginning of the
     year.  David comes back in November to release 2.12, but he won't
     touch Autoconf anymore after this year, and Autoconf then really
     stagnates.  The desolate Autoconf `ChangeLog' for 1997 lists only
     7 commits.

1997-02-28 <[email protected]> list alive
     The mailing list is announced as follows:
          I've created the "automake" mailing list.  It is
          "[email protected]".  Administrivia, as always, to
          [email protected].

          The charter of this list is discussion of automake, autoconf, and
          other configuration/portability tools (eg libtool).  It is expected
          that discussion will range from pleas for help all the way up to
          patches.

          This list is archived on the FSF machines.  Offhand I don't know if
          you can get the archive without an account there.

          This list is open to anybody who wants to join.  Tell all your
          friends!
          -- Tom Tromey

     Before that people were discussing Automake privately, on the Gnits
     mailing list (which is not public either), and less frequently on
     `gnu.misc.discuss'.

     `gnu.ai.mit.edu' is now `gnu.org', in case you never noticed.  The
     archives of the early years of the `[email protected]' list have
     been lost, so today it is almost impossible to find traces of
     discussions that occurred before 1999.  This has been annoying
     more than once, as such discussions can be useful to understand
     the rationale behind a piece of uncommented code that was
     introduced back then.

1997-06-22 Automake 1.2
     Automake developments continues, and more and more new Autoconf
     macros are required.  Distributing them in `aclocal.m4' and
     requiring people to browse this file to extract the relevant
     macros becomes uncomfortable.  Ideally, some of them should be
     contributed to Autoconf so that they can be used directly, however
     Autoconf is currently inactive.  Automake 1.2 consequently
     introduces `aclocal' (`aclocal' was actually started on
     1996-07-28), a tool that automatically constructs an `aclocal.m4'
     file from a repository of third-party macros.  Because Autoconf has
     stalled, Automake also becomes a kind of repository for such
     third-party macros, even macros completely unrelated to Automake
     (for instance macros that fix broken Autoconf macros).

     The 1.2 release contains 20 macros, among which the
     `AM_INIT_AUTOMAKE' macro that simplifies the creation of
     `configure.in'.

     Libtool is fully supported using `*_LTLIBRARIES'.

     The missing script is introduced by Franc,ois Pinard; it is meant
     to be a better solution than `AM_MAINTAINER_MODE' (*note
     maintainer-mode::).

     Conditionals support was implemented by Ian Lance Taylor.  At the
     time, Tom and Ian were working on an internal project at Cygnus.
     They were using ILU, which is pretty similar to CORBA.  They
     wanted to integrate ILU into their build, which was all
     `configure'-based, and Ian thought that adding conditionals to
     `automake' was simpler than doing all the work in `configure'
     (which was the standard at the time).  So this was actually funded
     by Cygnus.

     This very useful but tricky feature will take a lot of time to
     stabilize.  (At the time this text is written, there are still
     primaries that have not been updated to support conditional
     definitions in Automake 1.9.)

     The `automake' script has almost doubled: 6089 lines of Perl, plus
     1294 lines of `Makefile' fragments.

1997-07-08 Gordon Matzigkeit releases Libtool 1.0.

1998-04-05 Automake 1.3
     This is a small advance compared to 1.2.  It add support for
     assembly, and preliminary support for Java.

     Perl 5.004_04 is out, but fixes to support Perl 4 are still
     regularly submitted whenever Automake breaks it.

1998-09-06 `sourceware.cygnus.com' is on-line.
     Sourceware was setup by Jason Molenda to host open source projects.

1998-09-19  Automake CVS repository moved to `sourceware.cygnus.com'
1998-10-26  `sourceware.cygnus.com' announces it hosts Automake
     Automake is now hosted on `sourceware.cygnus.com'.  It has a
     publicly accessible CVS repository.  This CVS repository is a copy
     of the one Tom was using on his machine, which in turn is based on
     a copy of the CVS repository of David MacKenzie.  This is why we
     still have to full source history.  (Automake is still on
     Sourceware today, but the host has been renamed to
     `sources.redhat.com'.)

     The oldest file in the administrative directory of the CVS
     repository that was created on Sourceware is dated 1998-09-19,
     while the announcement that `automake' and `autoconf' had joined
     `sourceware' was made on 1998-10-26.  They were among the first
     projects to be hosted there.

     The heedful reader will have noticed Automake was exactly
     4-year-old on 1998-09-19.

1999-01-05 Ben Elliston releases Autoconf 2.13.

1999-01-14 Automake 1.4
     This release adds support for Fortran 77 and for the `include'
     statement.  Also, `+=' assignments are introduced, but it is still
     quite easy to fool Automake when mixing this with conditionals.

     These two releases, Automake 1.4 and Autoconf 2.13 makes a duo that
     will be used together for years.

     `automake' is 7228 lines, plus 1591 lines of Makefile fragment, 20
     macros (some 1.3 macros were finally contributed back to
     Autoconf), 197 test cases, and 51 pages of documentation.

1999-03-27 The `user-dep-branch' is created on the CVS repository.
     This implements a new dependency tracking schemed that should be
     able to handle automatic dependency tracking using any compiler
     (not just gcc) and any make (not just GNU `make').  In addition,
     the new scheme should be more reliable than the old one, as
     dependencies are generated on the end user's machine.  Alexandre
     Oliva creates depcomp for this purpose.

     *Note Dependency Tracking Evolution::, for more details about the
     evolution of automatic dependency tracking in Automake.

1999-11-21 The `user-dep-branch' is merged into the main trunk.
     This was a huge problem since we also had patches going in on the
     trunk.  The merge took a long time and was very painful.

2000-05-10
     Since September 1999 and until 2003, Akim Demaille will be
     zealously revamping Autoconf.

          I think the next release should be called "3.0".
          Let's face it: you've basically rewritten autoconf.
          Every weekend there are 30 new patches.
          I don't see how we could call this "2.15" with a straight
          face.
          - Tom Tromey on <[email protected]>

     Actually Akim works like a submarine: he will pile up patches
     while he works off-line during the weekend, and flush them in
     batch when he resurfaces on Monday.

2001-01-24
     On this Wednesday, Autoconf 2.49c, the last beta before Autoconf
     2.50 is out, and Akim has to find something to do during his
     week-end :)

2001-01-28
     Akim sends a batch of 14 patches to <[email protected]>.

          Aiieeee!  I was dreading the day that the Demaillator turned
          his sights on automake... and now it has arrived! - Tom Tromey

     It's only the beginning: in two months he will send 192 patches.
     Then he would slow down so Tom can catch up and review all this.
     Initially Tom actually read all these patches, then he probably
     trustingly answered OK to most of them, and finally gave up and
     let Akim apply whatever he wanted.  There was no way to keep up
     with that patch rate.

          Anyway the patch below won't apply since it predates Akim's
          sourcequake; I have yet to figure where the relevant passage
          has been moved :) - Alexandre Duret-Lutz

     All these patches were sent to and discussed on
     <[email protected]>, so subscribed users were literally drown in
     technical mails.  Eventually, the <[email protected]>
     mailing list was created in May.

     Year after year, Automake had drifted away from its initial design:
     construct `Makefile.in' by assembling various `Makefile'
     fragments.  In 1.4, lots of `Makefile' rules are being emitted at
     various places in the `automake' script itself; this does not help
     ensuring a consistent treatment of these rules (for instance
     making sure that user-defined rules override Automake's own rules).
     One of Akim's goal was moving all these hard-coded rules to
     separate `Makefile' fragments, so the logic could be centralized
     in a `Makefile' fragment processor.

     Another significant contribution of Akim is the interface with the
     "trace" feature of Autoconf.  The way to scan `configure.in' at
     this time was to read the file and grep the various macro of
     interest to Automake.  Doing so could break in many unexpected
     ways; automake could miss some definition (for instance
     `AC_SUBST([$1], [$2])' where the arguments are known only when M4
     is run), or conversely it could detect some macro that was not
     expanded (because it is called conditionally).  In the CVS version
     of Autoconf, Akim had implemented the `--trace' option, which
     provides accurate information about where macros are actually
     called and with what arguments.  Akim will equip Automake with a
     second `configure.in' scanner that uses this `--trace' interface.
     Since it was not sensible to drop the Autoconf 2.13 compatibility
     yet, this experimental scanner was only used when an environment
     variable was set, the traditional grep-scanner being still the
     default.

2001-04-25 Gary V. Vaughan releases Libtool 1.4
     It has been more than two years since Automake 1.4, CVS Automake
     has suffered lot's of heavy changes and still is not ready for
     release.  Libtool 1.4 had to be distributed with a patch against
     Automake 1.4.

2001-05-08 Automake 1.4-p1
2001-05-24 Automake 1.4-p2
     Gary V. Vaughan, the principal Libtool maintainer, makes a "patch
     release" of Automake:

          The main purpose of this release is to have a stable automake
          which is compatible with the latest stable libtool.

     The release also contains obvious fixes for bugs in Automake 1.4,
     some of which were reported almost monthly.

2001-05-21 Akim Demaille releases Autoconf 2.50

2001-06-07 Automake 1.4-p3
2001-06-10 Automake 1.4-p4
2001-07-15 Automake 1.4-p5
     Gary continues his patch-release series.  These also add support
     for some new Autoconf 2.50 idioms.  Essentially, Autoconf now
     advocates `configure.ac' over `configure.in', and it introduces a
     new syntax for `AC_OUTPUT'ing files.

2001-08-23 Automake 1.5
     A major and long-awaited release, that comes more than two years
     after 1.4.  It brings many changes, among which:
        * The new dependency tracking scheme that uses `depcomp'.
          Aside from the improvement on the dependency tracking itself
          (*note Dependency Tracking Evolution::), this also
          streamlines the use of automake generated `Makefile.in's as
          the `Makefile.in's used during development are now the same
          as those used in distributions.  Before that the
          `Makefile.in's generated for maintainers required GNU `make'
          and GCC, they were different from the portable `Makefile'
          generated for distribution; this was causing some confusion.

        * Support for per-target compilation flags.

        * Support for reference to files in subdirectories in most
          `Makefile.am' variables.

        * Introduction of the `dist_', `nodist_', and `nobase_'
          prefixes.

        * Perl 4 support is finally dropped.

     1.5 did broke several packages that worked with 1.4.  Enough so
     that Linux distributions could not easily install the new Automake
     version without breaking many of the packages for which they had
     to run `automake'.

     Some of these breakages were effectively bugs that would
     eventually be fixed in the next release.  However, a lot of damage
     was caused by some changes made deliberately to render Automake
     stricter on some setup we did consider bogus.  For instance, `make
     distcheck' was improved to check that `make uninstall' did remove
     all the files `make install' installed, that `make distclean' did
     not omit some file, and that a VPATH build would work even if the
     source directory was read-only.  Similarly, Automake now rejects
     multiple definitions of the same variable (because that would mix
     very badly with conditionals), and `+=' assignments with no
     previous definition.  Because these changes all occurred suddenly
     after 1.4 had been established for more that two years, it hurt
     users.

     To make matter worse, meanwhile Autoconf (now at version 2.52) was
     facing similar troubles, for similar reasons.

2002-03-05 Automake 1.6
     This release introduced versioned installation (*note API
     versioning::).  This was mainly pushed by Havoc Pennington, taking
     the GNOME source tree as motive: due to incompatibilities between
     the autotools it's impossible for the GNOME packages to switch to
     Autoconf 2.53 and Automake 1.5 all at once, so they are currently
     stuck with Autoconf 2.13 and Automake 1.4.

     The idea was to call this version `automake-1.6', call all its
     bug-fix versions identically, and switch to `automake-1.7' for the
     next release that adds new features or changes some rules.  This
     scheme implies maintaining a bug-fix branch in addition to the
     development trunk, which means more work from the maintainer, but
     providing regular bug-fix releases proved to be really worthwhile.

     Like 1.5, 1.6 also introduced a bunch of incompatibilities, meant
     or not.  Perhaps the more annoying was the dependence on the newly
     released Autoconf 2.53.  Autoconf seemed to have stabilized enough
     since its explosive 2.50 release, and included changes required to
     fix some bugs in Automake.  In order to upgrade to Automake 1.6,
     people now had to upgrade Autoconf too; for some packages it was
     no picnic.

     While versioned installation helped people to upgrade, it also
     unfortunately allowed people not to upgrade.  At the time of
     writing, some Linux distributions are shipping packages for
     Automake 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9.  Most of these still
     install 1.4 by default.  Some distribution also call 1.4 the
     "stable" version, and present "1.9" as the development version;
     this does not really makes sense since 1.9 is way more solid than
     1.4.  All this does not help the newcomer.

2002-04-11 Automake 1.6.1
     1.6, and the upcoming 1.4-p6 release were the last release by Tom.
     This one and those following will be handled by Alexandre
     Duret-Lutz.  Tom is still around, and will be there until about
     1.7, but his interest into Automake is drifting away towards
     projects like `gcj'.

     Alexandre has been using Automake since 2000, and started to
     contribute mostly on Akim's incitement (Akim and Alexandre have
     been working in the same room from 1999 to 2002).  In 2001 and
     2002 he had a lot of free time to enjoy hacking Automake.

2002-06-14 Automake 1.6.2

2002-07-28 Automake 1.6.3
2002-07-28 Automake 1.4-p6
     Two releases on the same day.  1.6.3 is a bug-fix release.

     Tom Tromey backported the versioned installation mechanism on the
     1.4 branch, so that Automake 1.6.x and Automake 1.4-p6 could be
     installed side by side.  Another request from the GNOME folks.

2002-09-25 Automake 1.7
     This release switches to the new `configure.ac' scanner Akim was
     experimenting in 1.5.

2002-10-16 Automake 1.7.1
2002-12-06 Automake 1.7.2
2003-02-20 Automake 1.7.3
2003-04-23 Automake 1.7.4

2003-07-10 Automake 1.7.6
2003-09-07 Automake 1.7.7
2003-10-07 Automake 1.7.8
     Many bug-fix releases.  1.7 lasted because the development version
     (upcoming 1.8) was suffering some major internal revamping.

2003-10-26 Automake on screen
     Episode 49, `Repercussions', in the third season of the `Alias' TV
     show is first aired.

     Marshall, one of the character, is working on a computer virus
     that he has to modify before it gets into the wrong hands or
     something like that.  The screenshots you see do not show any
     program code, they show a `Makefile.in' `generated by automake'...

2003-11-09 Automake 1.7.9

2003-12-10 Automake 1.8
     The most striking update is probably that of `aclocal'.

     `aclocal' now uses `m4_include' in the produced `aclocal.m4' when
     the included macros are already distributed with the package (an
     idiom used in many packages), which reduces code duplication.
     Many people liked that, but in fact this change was really
     introduced to fix a bug in rebuild rules: `Makefile.in' must be
     rebuilt whenever a dependency of `configure' changes, but all the
     `m4' files included in `aclocal.m4' where unknown from `automake'.
     Now `automake' can just trace the `m4_include's to discover the
     dependencies.

     `aclocal' also starts using the `--trace' Autoconf option in order
     to discover used macros more accurately.  This will turn out to be
     very tricky (later releases will improve this) as people had
     devised many ways to cope with the limitation of previous
     `aclocal' versions, notably using handwritten `m4_include's:
     `aclocal' must make sure not to redefine a rule that is already
     included by such statement.

     Automake also has seen its guts rewritten.  Although this rewriting
     took a lot of efforts, it is only apparent to the users in that
     some constructions previously disallowed by the implementation now
     work nicely.  Conditionals, Locations, Variable and Rule
     definitions, Options: these items on which Automake works have
     been rewritten as separate Perl modules, and documented.

2004-01-11 Automake 1.8.1

2004-05-16 Automake 1.8.5

2004-07-28 Automake 1.9
     This release tries to simplify the compilation rules it outputs to
     reduce the size of the Makefile.  The complaint initially come from
     the libgcj developers.  Their `Makefile.in' generated with
     Automake 1.4 and custom build rules (1.4 did not support compiled
     Java) is 250KB.  The one generated by 1.8 was over 9MB!  1.9 gets
     it down to 1.2MB.

     Aside from this it contains mainly minor changes and bug-fixes.

2004-08-11 Automake 1.9.1
2004-09-19 Automake 1.9.2
     Automake has ten years.  This chapter of the manual was initially
     written for this occasion.

27.2 Dependency Tracking in Automake
====================================

Over the years Automake has deployed three different dependency
tracking methods.  Each method, including the current one, has had
flaws of various sorts.  Here we lay out the different dependency
tracking methods, their flaws, and their fixes.  We conclude with
recommendations for tool writers, and by indicating future directions
for dependency tracking work in Automake.

27.2.1 First Take
-----------------

Description
...........

Our first attempt at automatic dependency tracking was based on the
method recommended by GNU `make'.  (*note Generating Prerequisites
Automatically: (make)Automatic Prerequisites.)

   This version worked by precomputing dependencies ahead of time.  For
each source file, it had a special `.P' file that held the
dependencies.  There was a rule to generate a `.P' file by invoking the
compiler appropriately.  All such `.P' files were included by the
`Makefile', thus implicitly becoming dependencies of `Makefile'.

Bugs
....

This approach had several critical bugs.

   * The code to generate the `.P' file relied on `gcc'.  (A
     limitation, not technically a bug.)

   * The dependency tracking mechanism itself relied on GNU `make'.  (A
     limitation, not technically a bug.)

   * Because each `.P' file was a dependency of `Makefile', this meant
     that dependency tracking was done eagerly by `make'.  For
     instance, `make clean' would cause all the dependency files to be
     updated, and then immediately removed.  This eagerness also caused
     problems with some configurations; if a certain source file could
     not be compiled on a given architecture for some reason,
     dependency tracking would fail, aborting the entire build.

   * As dependency tracking was done as a pre-pass, compile times were
     doubled-the compiler had to be run twice per source file.

   * `make dist' re-ran `automake' to generate a `Makefile' that did
     not have automatic dependency tracking (and that was thus portable
     to any version of `make').  In order to do this portably, Automake
     had to scan the dependency files and remove any reference that was
     to a source file not in the distribution.  This process was
     error-prone.  Also, if `make dist' was run in an environment where
     some object file had a dependency on a source file that was only
     conditionally created, Automake would generate a `Makefile' that
     referred to a file that might not appear in the end user's build.
     A special, hacky mechanism was required to work around this.

Historical Note
...............

The code generated by Automake is often inspired by the `Makefile'
style of a particular author.  In the case of the first implementation
of dependency tracking, I believe the impetus and inspiration was Jim
Meyering.  (I could be mistaken.  If you know otherwise feel free to
correct me.)

27.2.2 Dependencies As Side Effects
-----------------------------------

Description
...........

The next refinement of Automake's automatic dependency tracking scheme
was to implement dependencies as side effects of the compilation.  This
was aimed at solving the most commonly reported problems with the first
approach.  In particular we were most concerned with eliminating the
weird rebuilding effect associated with make clean.

   In this approach, the `.P' files were included using the `-include'
command, which let us create these files lazily.  This avoided the
`make clean' problem.

   We only computed dependencies when a file was actually compiled.
This avoided the performance penalty associated with scanning each file
twice.  It also let us avoid the other problems associated with the
first, eager, implementation.  For instance, dependencies would never
be generated for a source file that was not compilable on a given
architecture (because it in fact would never be compiled).

Bugs
....

   * This approach also relied on the existence of `gcc' and GNU
     `make'.  (A limitation, not technically a bug.)

   * Dependency tracking was still done by the developer, so the
     problems from the first implementation relating to massaging of
     dependencies by `make dist' were still in effect.

   * This implementation suffered from the "deleted header file"
     problem.  Suppose a lazily-created `.P' file includes a dependency
     on a given header file, like this:

          maude.o: maude.c something.h

     Now suppose that the developer removes `something.h' and updates
     `maude.c' so that this include is no longer needed.  If he runs
     `make', he will get an error because there is no way to create
     `something.h'.

     We fixed this problem in a later release by further massaging the
     output of `gcc' to include a dummy dependency for each header file.

27.2.3 Dependencies for the User
--------------------------------

Description
...........

The bugs associated with `make dist', over time, became a real problem.
Packages using Automake were being built on a large number of
platforms, and were becoming increasingly complex.  Broken dependencies
were distributed in "portable" `Makefile.in's, leading to user
complaints.  Also, the requirement for `gcc' and GNU `make' was a
constant source of bug reports.  The next implementation of dependency
tracking aimed to remove these problems.

   We realized that the only truly reliable way to automatically track
dependencies was to do it when the package itself was built.  This
meant discovering a method portable to any version of make and any
compiler.  Also, we wanted to preserve what we saw as the best point of
the second implementation: dependency computation as a side effect of
compilation.

   In the end we found that most modern make implementations support
some form of include directive.  Also, we wrote a wrapper script that
let us abstract away differences between dependency tracking methods for
compilers.  For instance, some compilers cannot generate dependencies
as a side effect of compilation.  In this case we simply have the
script run the compiler twice.  Currently our wrapper script
(`depcomp') knows about twelve different compilers (including a
"compiler" that simply invokes `makedepend' and then the real compiler,
which is assumed to be a standard Unix-like C compiler with no way to
do dependency tracking).

Bugs
....

   * Running a wrapper script for each compilation slows down the build.

   * Many users don't really care about precise dependencies.

   * This implementation, like every other automatic dependency tracking
     scheme in common use today (indeed, every one we've ever heard of),
     suffers from the "duplicated new header" bug.

     This bug occurs because dependency tracking tools, such as the
     compiler, only generate dependencies on the successful opening of a
     file, and not on every probe.

     Suppose for instance that the compiler searches three directories
     for a given header, and that the header is found in the third
     directory.  If the programmer erroneously adds a header file with
     the same name to the first directory, then a clean rebuild from
     scratch could fail (suppose the new header file is buggy), whereas
     an incremental rebuild will succeed.

     What has happened here is that people have a misunderstanding of
     what a dependency is.  Tool writers think a dependency encodes
     information about which files were read by the compiler.  However,
     a dependency must actually encode information about what the
     compiler tried to do.

     This problem is not serious in practice.  Programmers typically do
     not use the same name for a header file twice in a given project.
     (At least, not in C or C++.  This problem may be more troublesome
     in Java.)  This problem is easy to fix, by modifying dependency
     generators to record every probe, instead of every successful open.

   * Since automake generates dependencies as a side effect of
     compilation, there is a bootstrapping problem when header files
     are generated by running a program.  The problem is that, the
     first time the build is done, there is no way by default to know
     that the headers are required, so make might try to run a
     compilation for which the headers have not yet been built.

     This was also a problem in the previous dependency tracking
     implementation.

     The current fix is to use `BUILT_SOURCES' to list built headers
     (*note Sources::).  This causes them to be built before any other
     other build rules are run.  This is unsatisfactory as a general
     solution, however in practice it seems sufficient for most actual
     programs.

   This code is used since Automake 1.5.

   In GCC 3.0, we managed to convince the maintainers to add special
command-line options to help Automake more efficiently do its job.  We
hoped this would let us avoid the use of a wrapper script when
Automake's automatic dependency tracking was used with `gcc'.

   Unfortunately, this code doesn't quite do what we want.  In
particular, it removes the dependency file if the compilation fails;
we'd prefer that it instead only touch the file in any way if the
compilation succeeds.

   Nevertheless, since Automake 1.7, when a recent `gcc' is detected at
`configure' time, we inline the dependency-generation code and do not
use the `depcomp' wrapper script.  This makes compilations faster for
those using this compiler (probably our primary user base).  The
counterpart is that because we have to encode two compilation rules in
`Makefile' (with or without `depcomp'), the produced `Makefile's are
larger.

27.2.4 Techniques for Computing Dependencies
--------------------------------------------

There are actually several ways for a build tool like Automake to cause
tools to generate dependencies.

`makedepend'
     This was a commonly-used method in the past.  The idea is to run a
     special program over the source and have it generate dependency
     information.  Traditional implementations of `makedepend' ere not
     completely precise; ordinarily they were conservative and
     discovered too many dependencies.

The tool
     An obvious way to generate dependencies is to simply write the
     tool so that it can generate the information needed by the build
     tool.  This is also the most portable method.  Many compilers have
     an option to generate dependencies.  Unfortunately, not all tools
     provide such an option.

The file system
     It is possible to write a special file system that tracks opens,
     reads, writes, etc, and then feed this information back to the
     build tool.  `clearmake' does this.  This is a very powerful
     technique, as it doesn't require cooperation from the tool.
     Unfortunately it is also very difficult to implement and also not
     practical in the general case.

`LD_PRELOAD'
     Rather than use the file system, one could write a special library
     to intercept `open' and other syscalls.  This technique is also
     quite powerful, but unfortunately it is not portable enough for
     use in `automake'.

27.2.5 Recommendations for Tool Writers
---------------------------------------

We think that every compilation tool ought to be able to generate
dependencies as a side effect of compilation.  Furthermore, at least
while `make'-based tools are nearly universally in use (at least in the
free software community), the tool itself should generate dummy
dependencies for header files, to avoid the deleted header file bug.
Finally, the tool should generate a dependency for each probe, instead
of each successful file open, in order to avoid the duplicated new
header bug.

27.2.6 Future Directions for Automake's Dependency Tracking
-----------------------------------------------------------

Currently, only languages and compilers understood by Automake can have
dependency tracking enabled.  We would like to see if it is practical
(and worthwhile) to let this support be extended by the user to
languages unknown to Automake.

A.1 GNU Free Documentation License
==================================

                      Version 1.2, November 2002

     Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
     51 Franklin St, Fifth Floor, Boston, MA  02110-1301, USA

     Everyone is permitted to copy and distribute verbatim copies
     of this license document, but changing it is not allowed.

  0. PREAMBLE

     The purpose of this License is to make a manual, textbook, or other
     functional and useful document "free" in the sense of freedom: to
     assure everyone the effective freedom to copy and redistribute it,
     with or without modifying it, either commercially or
     noncommercially.  Secondarily, this License preserves for the
     author and publisher a way to get credit for their work, while not
     being considered responsible for modifications made by others.

     This License is a kind of "copyleft", which means that derivative
     works of the document must themselves be free in the same sense.
     It complements the GNU General Public License, which is a copyleft
     license designed for free software.

     We have designed this License in order to use it for manuals for
     free software, because free software needs free documentation: a
     free program should come with manuals providing the same freedoms
     that the software does.  But this License is not limited to
     software manuals; it can be used for any textual work, regardless
     of subject matter or whether it is published as a printed book.
     We recommend this License principally for works whose purpose is
     instruction or reference.

  1. APPLICABILITY AND DEFINITIONS

     This License applies to any manual or other work, in any medium,
     that contains a notice placed by the copyright holder saying it
     can be distributed under the terms of this License.  Such a notice
     grants a world-wide, royalty-free license, unlimited in duration,
     to use that work under the conditions stated herein.  The
     "Document", below, refers to any such manual or work.  Any member
     of the public is a licensee, and is addressed as "you".  You
     accept the license if you copy, modify or distribute the work in a
     way requiring permission under copyright law.

     A "Modified Version" of the Document means any work containing the
     Document or a portion of it, either copied verbatim, or with
     modifications and/or translated into another language.

     A "Secondary Section" is a named appendix or a front-matter section
     of the Document that deals exclusively with the relationship of the
     publishers or authors of the Document to the Document's overall
     subject (or to related matters) and contains nothing that could
     fall directly within that overall subject.  (Thus, if the Document
     is in part a textbook of mathematics, a Secondary Section may not
     explain any mathematics.)  The relationship could be a matter of
     historical connection with the subject or with related matters, or
     of legal, commercial, philosophical, ethical or political position
     regarding them.

     The "Invariant Sections" are certain Secondary Sections whose
     titles are designated, as being those of Invariant Sections, in
     the notice that says that the Document is released under this
     License.  If a section does not fit the above definition of
     Secondary then it is not allowed to be designated as Invariant.
     The Document may contain zero Invariant Sections.  If the Document
     does not identify any Invariant Sections then there are none.

     The "Cover Texts" are certain short passages of text that are
     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
     that says that the Document is released under this License.  A
     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
     be at most 25 words.

     A "Transparent" copy of the Document means a machine-readable copy,
     represented in a format whose specification is available to the
     general public, that is suitable for revising the document
     straightforwardly with generic text editors or (for images
     composed of pixels) generic paint programs or (for drawings) some
     widely available drawing editor, and that is suitable for input to
     text formatters or for automatic translation to a variety of
     formats suitable for input to text formatters.  A copy made in an
     otherwise Transparent file format whose markup, or absence of
     markup, has been arranged to thwart or discourage subsequent
     modification by readers is not Transparent.  An image format is
     not Transparent if used for any substantial amount of text.  A
     copy that is not "Transparent" is called "Opaque".

     Examples of suitable formats for Transparent copies include plain
     ASCII without markup, Texinfo input format, LaTeX input format,
     SGML or XML using a publicly available DTD, and
     standard-conforming simple HTML, PostScript or PDF designed for
     human modification.  Examples of transparent image formats include
     PNG, XCF and JPG.  Opaque formats include proprietary formats that
     can be read and edited only by proprietary word processors, SGML or
     XML for which the DTD and/or processing tools are not generally
     available, and the machine-generated HTML, PostScript or PDF
     produced by some word processors for output purposes only.

     The "Title Page" means, for a printed book, the title page itself,
     plus such following pages as are needed to hold, legibly, the
     material this License requires to appear in the title page.  For
     works in formats which do not have any title page as such, "Title
     Page" means the text near the most prominent appearance of the
     work's title, preceding the beginning of the body of the text.

     A section "Entitled XYZ" means a named subunit of the Document
     whose title either is precisely XYZ or contains XYZ in parentheses
     following text that translates XYZ in another language.  (Here XYZ
     stands for a specific section name mentioned below, such as
     "Acknowledgements", "Dedications", "Endorsements", or "History".)
     To "Preserve the Title" of such a section when you modify the
     Document means that it remains a section "Entitled XYZ" according
     to this definition.

     The Document may include Warranty Disclaimers next to the notice
     which states that this License applies to the Document.  These
     Warranty Disclaimers are considered to be included by reference in
     this License, but only as regards disclaiming warranties: any other
     implication that these Warranty Disclaimers may have is void and
     has no effect on the meaning of this License.

  2. VERBATIM COPYING

     You may copy and distribute the Document in any medium, either
     commercially or noncommercially, provided that this License, the
     copyright notices, and the license notice saying this License
     applies to the Document are reproduced in all copies, and that you
     add no other conditions whatsoever to those of this License.  You
     may not use technical measures to obstruct or control the reading
     or further copying of the copies you make or distribute.  However,
     you may accept compensation in exchange for copies.  If you
     distribute a large enough number of copies you must also follow
     the conditions in section 3.

     You may also lend copies, under the same conditions stated above,
     and you may publicly display copies.

  3. COPYING IN QUANTITY

     If you publish printed copies (or copies in media that commonly
     have printed covers) of the Document, numbering more than 100, and
     the Document's license notice requires Cover Texts, you must
     enclose the copies in covers that carry, clearly and legibly, all
     these Cover Texts: Front-Cover Texts on the front cover, and
     Back-Cover Texts on the back cover.  Both covers must also clearly
     and legibly identify you as the publisher of these copies.  The
     front cover must present the full title with all words of the
     title equally prominent and visible.  You may add other material
     on the covers in addition.  Copying with changes limited to the
     covers, as long as they preserve the title of the Document and
     satisfy these conditions, can be treated as verbatim copying in
     other respects.

     If the required texts for either cover are too voluminous to fit
     legibly, you should put the first ones listed (as many as fit
     reasonably) on the actual cover, and continue the rest onto
     adjacent pages.

     If you publish or distribute Opaque copies of the Document
     numbering more than 100, you must either include a
     machine-readable Transparent copy along with each Opaque copy, or
     state in or with each Opaque copy a computer-network location from
     which the general network-using public has access to download
     using public-standard network protocols a complete Transparent
     copy of the Document, free of added material.  If you use the
     latter option, you must take reasonably prudent steps, when you
     begin distribution of Opaque copies in quantity, to ensure that
     this Transparent copy will remain thus accessible at the stated
     location until at least one year after the last time you
     distribute an Opaque copy (directly or through your agents or
     retailers) of that edition to the public.

     It is requested, but not required, that you contact the authors of
     the Document well before redistributing any large number of
     copies, to give them a chance to provide you with an updated
     version of the Document.

  4. MODIFICATIONS

     You may copy and distribute a Modified Version of the Document
     under the conditions of sections 2 and 3 above, provided that you
     release the Modified Version under precisely this License, with
     the Modified Version filling the role of the Document, thus
     licensing distribution and modification of the Modified Version to
     whoever possesses a copy of it.  In addition, you must do these
     things in the Modified Version:

       A. Use in the Title Page (and on the covers, if any) a title
          distinct from that of the Document, and from those of
          previous versions (which should, if there were any, be listed
          in the History section of the Document).  You may use the
          same title as a previous version if the original publisher of
          that version gives permission.

       B. List on the Title Page, as authors, one or more persons or
          entities responsible for authorship of the modifications in
          the Modified Version, together with at least five of the
          principal authors of the Document (all of its principal
          authors, if it has fewer than five), unless they release you
          from this requirement.

       C. State on the Title page the name of the publisher of the
          Modified Version, as the publisher.

       D. Preserve all the copyright notices of the Document.

       E. Add an appropriate copyright notice for your modifications
          adjacent to the other copyright notices.

       F. Include, immediately after the copyright notices, a license
          notice giving the public permission to use the Modified
          Version under the terms of this License, in the form shown in
          the Addendum below.

       G. Preserve in that license notice the full lists of Invariant
          Sections and required Cover Texts given in the Document's
          license notice.

       H. Include an unaltered copy of this License.

       I. Preserve the section Entitled "History", Preserve its Title,
          and add to it an item stating at least the title, year, new
          authors, and publisher of the Modified Version as given on
          the Title Page.  If there is no section Entitled "History" in
          the Document, create one stating the title, year, authors,
          and publisher of the Document as given on its Title Page,
          then add an item describing the Modified Version as stated in
          the previous sentence.

       J. Preserve the network location, if any, given in the Document
          for public access to a Transparent copy of the Document, and
          likewise the network locations given in the Document for
          previous versions it was based on.  These may be placed in
          the "History" section.  You may omit a network location for a
          work that was published at least four years before the
          Document itself, or if the original publisher of the version
          it refers to gives permission.

       K. For any section Entitled "Acknowledgements" or "Dedications",
          Preserve the Title of the section, and preserve in the
          section all the substance and tone of each of the contributor
          acknowledgements and/or dedications given therein.

       L. Preserve all the Invariant Sections of the Document,
          unaltered in their text and in their titles.  Section numbers
          or the equivalent are not considered part of the section
          titles.

       M. Delete any section Entitled "Endorsements".  Such a section
          may not be included in the Modified Version.

       N. Do not retitle any existing section to be Entitled
          "Endorsements" or to conflict in title with any Invariant
          Section.

       O. Preserve any Warranty Disclaimers.

     If the Modified Version includes new front-matter sections or
     appendices that qualify as Secondary Sections and contain no
     material copied from the Document, you may at your option
     designate some or all of these sections as invariant.  To do this,
     add their titles to the list of Invariant Sections in the Modified
     Version's license notice.  These titles must be distinct from any
     other section titles.

     You may add a section Entitled "Endorsements", provided it contains
     nothing but endorsements of your Modified Version by various
     parties--for example, statements of peer review or that the text
     has been approved by an organization as the authoritative
     definition of a standard.

     You may add a passage of up to five words as a Front-Cover Text,
     and a passage of up to 25 words as a Back-Cover Text, to the end
     of the list of Cover Texts in the Modified Version.  Only one
     passage of Front-Cover Text and one of Back-Cover Text may be
     added by (or through arrangements made by) any one entity.  If the
     Document already includes a cover text for the same cover,
     previously added by you or by arrangement made by the same entity
     you are acting on behalf of, you may not add another; but you may
     replace the old one, on explicit permission from the previous
     publisher that added the old one.

     The author(s) and publisher(s) of the Document do not by this
     License give permission to use their names for publicity for or to
     assert or imply endorsement of any Modified Version.

  5. COMBINING DOCUMENTS

     You may combine the Document with other documents released under
     this License, under the terms defined in section 4 above for
     modified versions, provided that you include in the combination
     all of the Invariant Sections of all of the original documents,
     unmodified, and list them all as Invariant Sections of your
     combined work in its license notice, and that you preserve all
     their Warranty Disclaimers.

     The combined work need only contain one copy of this License, and
     multiple identical Invariant Sections may be replaced with a single
     copy.  If there are multiple Invariant Sections with the same name
     but different contents, make the title of each such section unique
     by adding at the end of it, in parentheses, the name of the
     original author or publisher of that section if known, or else a
     unique number.  Make the same adjustment to the section titles in
     the list of Invariant Sections in the license notice of the
     combined work.

     In the combination, you must combine any sections Entitled
     "History" in the various original documents, forming one section
     Entitled "History"; likewise combine any sections Entitled
     "Acknowledgements", and any sections Entitled "Dedications".  You
     must delete all sections Entitled "Endorsements."

  6. COLLECTIONS OF DOCUMENTS

     You may make a collection consisting of the Document and other
     documents released under this License, and replace the individual
     copies of this License in the various documents with a single copy
     that is included in the collection, provided that you follow the
     rules of this License for verbatim copying of each of the
     documents in all other respects.

     You may extract a single document from such a collection, and
     distribute it individually under this License, provided you insert
     a copy of this License into the extracted document, and follow
     this License in all other respects regarding verbatim copying of
     that document.

  7. AGGREGATION WITH INDEPENDENT WORKS

     A compilation of the Document or its derivatives with other
     separate and independent documents or works, in or on a volume of
     a storage or distribution medium, is called an "aggregate" if the
     copyright resulting from the compilation is not used to limit the
     legal rights of the compilation's users beyond what the individual
     works permit.  When the Document is included in an aggregate, this
     License does not apply to the other works in the aggregate which
     are not themselves derivative works of the Document.

     If the Cover Text requirement of section 3 is applicable to these
     copies of the Document, then if the Document is less than one half
     of the entire aggregate, the Document's Cover Texts may be placed
     on covers that bracket the Document within the aggregate, or the
     electronic equivalent of covers if the Document is in electronic
     form.  Otherwise they must appear on printed covers that bracket
     the whole aggregate.

  8. TRANSLATION

     Translation is considered a kind of modification, so you may
     distribute translations of the Document under the terms of section
     4.  Replacing Invariant Sections with translations requires special
     permission from their copyright holders, but you may include
     translations of some or all Invariant Sections in addition to the
     original versions of these Invariant Sections.  You may include a
     translation of this License, and all the license notices in the
     Document, and any Warranty Disclaimers, provided that you also
     include the original English version of this License and the
     original versions of those notices and disclaimers.  In case of a
     disagreement between the translation and the original version of
     this License or a notice or disclaimer, the original version will

A.1.1 ADDENDUM: How to use this License for your documents
----------------------------------------------------------

To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and license
notices just after the title page:

       Copyright (C)  YEAR  YOUR NAME.
       Permission is granted to copy, distribute and/or modify this document
       under the terms of the GNU Free Documentation License, Version 1.2
       or any later version published by the Free Software Foundation;
       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
       Texts.  A copy of the license is included in the section entitled ``GNU
       Free Documentation License''.

   If you have Invariant Sections, Front-Cover Texts and Back-Cover
Texts, replace the "with...Texts." line with this:

         with the Invariant Sections being LIST THEIR TITLES, with
         the Front-Cover Texts being LIST, and with the Back-Cover Texts
         being LIST.

   If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.

   If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License, to
permit their use in free software.
