+ <sect2 id="outdated">
+ <heading>out-of-date</heading>
+ <p>
+For the testing migration script, "outdated" means: There are different
+versions in unstable for the release architectures (except for the
+architectures in fuckedarches; fuckedarches is an list of architectures
+that don't keep up (in update_out.py), but currently, it's empty).
+"outdated" has nothing whatsoever to do with the architectures this package
+has in testing.
+ <p>
+Consider this example:
+ <p>
+ <tt>
+ foo | alpha | arm
+---------+-------+----
+testing | 1 | -
+unstable | 1 | 2
+</tt>
+ <p>
+The package is out of date on alpha in unstable, and will not go to
+testing. And removing foo from testing would not help at all, the package
+is still out of date on alpha, and will not propagate to testing.
+ <p>
+However, if ftp-master removes a package in unstable (here on arm):
+ <p>
+ <tt>
+foo | alpha | arm | hurd-i386
+---------+-------+-----+----------
+testing | 1 | 1 | -
+unstable | 2 | - | 1
+ </tt>
+ <p>
+In this case, the package is up to date on all release architectures in
+unstable (and the extra hurd-i386 doesn't matter, as it's not a release
+architecture).
+ <p>
+Sometimes, the question is raised if it is possible to allow packages in
+that are not yet built on all architectures: No. Just plainly no. (Except
+if you maintain glibc or so.)
+
+ <sect2 id="removals">
+ <heading>Removals from testing</heading>

+be removed to allow b in.

+Of course, there is another reason to remove a package from testing: It's
+just too buggy (and having a single RC-bug is enough to be in this state).
+
+ <sect2 id="circular">
+ <heading>circular dependencies</heading>
+ <p>
+A situation that is not handled very well by britney is if package a
+depends on the new version of package b, and vice versa.
+ <p>
+An example of this is:
+ <p>
+ <tt>
+ | testing | unstable
+--+-----------------+------------
+a | 1; depends: b=1 | 2; depends: b=2
+b | 1; depends: a=1 | 2; depends: a=2
+ </tt>
+ <p>
+Package a is not considered for update, and package b also not.
+ <p>
+Currently, this requires some manual hinting from the release masters.
+Please, send mail to debian-release@lists.debian.org if that happens to
+one of your packages.
+
+
+ <sect2>
+ <heading>influence of package in testing</heading>
+ <p>
+Generally, there is nothing that the status of a package in testing means
+for transition of the next version from unstable to testing, with two
+exceptions: If the RC-bugginess of the package goes down, it may go in
+even if it is still RC-buggy. The second exception is if the version
+of the package in testing is out of sync on the different arches: Then
+any arch might just upgrade to the version of the source package;
+however, this can happen only if the package was previously forced
+through, or the arch is in fuckedarches.
+ <p>
+In summary this means: The only influence that a package being in testing
+has on a new version of the same package is that the new version might
+go in easier.
+
+ <sect2 id="details">
+ <heading>details</heading>
+ <p>
+If you are interested in details, this is how britney works:
+ <p>
+The packages are looked at to determine whether they are valid
+candidates. This gives the "update excuses". The most common reasons
+why a package is not considered are too young, RC-bugginess and out of
+date on some arches. For this part, the release managers have hammers
+of any size to force britney to consider a package. (Also, the base
+freeze is coded in that part of britney.) (There is a similar thing
+for binary-only updates, but this is not described here. If you're
+interessted in that, please use the code.)
+ <p>
+Now, the more complex part happens: Britney tries to update testing with
+the valid candidates; first, each package alone, and then larger and even
+larger sets of packages together. Each try is accepted if sarge is not
+more uninstallable after the update as before. (Before and after this part,
+some hints are processed; but as only release masters can hint, this is
+probably not so important for you.)
+ <p>
+If you want to see more details, you can look it up on
+merkel:/org/ftp.debian.org/testing/update_out/ (or there in

+ <sect1 id="t-p-u">
+ <heading>Direct updates to testing</heading>
+ <p>
+The testing distribution is fed with packages from unstable according to the rules
+explained above. However, in some cases, it is necessary to upload
+packages built only for testing. For that, you may want to
+upload to <em>testing-proposed-updates</em>.
+ <p>
+Keep in mind that packages uploaded there are not automatically processed, they
+have to go through the hands of the release manager. So you'd better have a good
+reason to upload there. In order to know what a good reason is in the
+release manager's eyes, you should read the instructions that he regularly
+gives on &email-debian-devel-announce;.
+ <p>
+You should not upload to <em>testing-proposed-updates</em> when you can update your
+packages through <em>unstable</em>. If you can't (for example because you have a
+newer development version in unstable), you may use it but it is recommended to ask
+the authorization of the release manager before. Even if a package is
+frozen, updates through unstable are possible, if the upload via unstable
+does not pulls an new dependency in.
+ <p>
+Version numbers are usually selected by adding the codename of the testing
+distribution and a incrementing number, like 1.2sarge1 for the first upload
+through testing-proposed-updates of the package version 1.2.

+ <heading>Frequently asked questions</heading>
+ <p>
+
+ <sect2 id="rc">
+ <heading>What are release-critical bugs, and how do they get counted?</headin>
+ <p>
+All bugs of some higher severities are by default considered release-critical; currently, these are critical, grave and serious bugs.
+ <p>
+Such bugs are presumed to have an impact on the chances that the package will be released with the stable release of Debian: in general, if a package has open release-critical bugs filed on it, it won't get into "testing", and consequently won't be released in "stable".
+ <p>
+The "testing" bug count for a package is considered to be roughly the bug count at the last point when the "testing" version equalled the "unstable" version. The bugs tagged woody or sarge will not be counted. Bugs with the sid tag will be counted, though.
+
+
+ <sect2>
+ <heading>How could installing a package into "testing" possibly break other packages?</heading>
+ <p>
+The structure of the distribution archives is such that they can only contain one version of a package; a package is defined by its name. So, when the source package acmefoo is installed into "testing", along with its binary packages acme-foo-bin, acme-bar-bin, libacme-foo1 and libacme-foo-dev, the old version is removed.
+ <p>
+However, the old version may have provided a binary package with an old soname of a library, such as libacme-foo0. Removing the old acmefoo will remove libacme-foo0, which will break any packages which depend on it.
+ <p>
+Evidently, this mainly affects packages which provide changing sets of binary packages in different versions (in turn, mainly libraries). However, it will also affect packages upon which versioned dependencies have been declared of the ==, <= or << varieties.
+ <p>
+When the set of binary packages provided by a source package change in this way, all the packages that depended on the old binaries will have to be updated to depend on the new binaries instead. Because installing such a source package into "testing" breaks all the packages that depended on it in "testing", some care now has to be taken: all the depending packages must be updated and ready to be installed themselves so that they won't be broken, and, once everything is ready, manual intervention by the release manager or an assistant is normally required.
+ <p>
+If you are having problems with complicated groups of packages like this, contact debian-devel or debian-release for help.

+ <heading>Suplimenting changelogs with NEWS.Debian files</heading>
+ <p>
+Important news about changes in a package can also be put in NEWS.Debian
+files. The news will be displayed by tools like apt-listchanges, before
+all the rest of the changelogs. This is the preferred means to let the user
+know about significant changes in a package. It is better than using
+debconf notes since it is less annoying and the user can go back and refer
+to the NEWS.Debian file after the install. And it's better than listing
+major changes in README.Debian, since the user can easily miss such notes.
+ <p>
+The file format is the same as a debian changelog file, but leave off
+the asterisks and describe each news item with a full paragraph when
+necessary rather than the more concise summaries that would go in a
+changelog. It's a good idea to run your file through dpkg-parsechangelog to
+check its formatting as it will not be automatically checked during build
+as the changelog is. Here is an example of a real NEWS.Debian file:
+<example>
+cron (3.0pl1-74) unstable; urgency=low
+
+ The checksecurity script is no longer included with the cron package:
+ it now has its own package, "checksecurity". If you liked the
+ functionality provided with that script, please install the new
+ package.

+The NEWS.Debian file is installed as
+/usr/share/doc/<package>/NEWS.Debian.gz. It is compressed, and
+always has that name even in Debian native packages. If you use debhelper,

+ <p>
+Unlike changelog files, you need not update NEWS.Debian files with every

+ <chapt id="l10n">Internationalizing, translating, being internationalized
+ and being translated
+ <p>
+Debian supports an ever-increasing number of natural languages. Even if you are
+native English speaker and do not speak any other language, it is part of your
+duty as a maintainer to be aware of issues of internationalization (abbreviated
+i18n because there are 18 letters between the 'i' and the 'n' in
+internationalization). Therefore, even if you are ok with English only
+programs, you should read most of this chapter.
+ <p>
+According to <url id="http://www.debian.org/doc/manuals/intro-i18n/"
+name="Introduction to i18n"> from Tomohiro KUBOTA, "I18N (internationalization)
+means modification of a software or related technologies so that a software can
+potentially handle multiple languages, customs, and so on in the world." while
+"L10N (localization) means implementation of a specific language for an already
+internationalized software."
+ <p>
+l10n and i18n are tied, but the difficulties related to each of them are very
+different. It's not really difficult to allow a program to change the language
+in which texts are displayed based on user settings, but it is very time
+consuming to actually translate these messages. On the other hand, setting the
+character encoding is trivial, but adapting the code to use several character
+encodings is a really hard problem.
+ <p>
+Letting alone the i18n problems, where no general receipt exist, there is
+actually no central infrastructure for l10n within Debian which could be
+compared to the dbuild mechanism for porting. So, most of the work has to be
+done manually.
+
+
+ <sect id="l10n-handling">How translations are handled within Debian
+ <p>
+Handling translation of the texts contained in a package is still a manual
+task, and the process depends on the kind of text you want to see translated.
+ <p>
+For program messages, the gettext infrastructure is used most of the time.
+Most of the time, the translation is handled upstream within projects like the
+<url id="http://www.iro.umontreal.ca/contrib/po/HTML/" name="Free Translation
+Project">, the <url id="http://developer.gnome.org/projects/gtp/" name="Gnome
+translation Project"> or the <url id="http://i18n.kde.org/" name="KDE one">.
+The only centralized resource within Debian is the <url
+id="http://www.debian.org/intl/l10n/" name="Central Debian translation
+statistics">, where you can find some statistics about the translation files
+found in the actual package, but no real infrastructure to ease the translation
+process.
+ <p>
+An effort to translate the package descriptions started long ago even if very
+few support is offered by the tools to actually use them (ie, only APT can use
+them, when configured correctly). There is nothing to do for the maintainers,
+and the translators should use the <url id="http://ddtp.debian.org/"
+name="DDTP">.
+ <p>
+For debconf templates, maintainer should use the po-debconf package to ease the
+work of translators, which could use the DDTP to do their work (but French and
+Brazilian teams don't). Some statistics can be found both on the DDTP site
+(about what is actually translated), and on the <url
+id="http://www.debian.org/intl/l10n/" name="Central Debian translation
+statistics"> site (about what is integrated in the packages).
+ p>
+For web pages, each l10n team has access to the relevant CVS, and the statistics
+are available from the Central Debian translation statistics site.
+ <p>
+For general documentation about Debian, the process is more or less the same
+than for the web pages (the translators have an access to the CVS), but there is
+no statistics pages.
+ <p>
+For package specific documentation (man pages, info document, other formats),
+almost everything have yet to be done. Most notably, the KDE project handles
+translation of its documentation in the same way as its program messages.

+ <p>
+For all other material (gettext files, man pages or other documentation), the
+best solution is to put your text somewhere on Internet, and ask on debian-i18n
+for a translation in the different languages. Some translation team members are
+subscribed to this list, and they will take care of the translation and of the

+in your mailbox.
+
+ <sect1 id="l10n-faqm-rev">How to get a given translation reviewed?
+ <p>
+>From time to time, individuals translate some texts included in your package

+you are not fluent in the given language. It is a good idea to send the
+document to the corresponding l10n mailing list, asking for a review. Once it
+has been done, you should feel more confident in the quality of the
+translation, and include it fearlessly into your package.
+
+ <sect1 id="l10n-faqm-update">How to get a given translation updated?
+ <p>
+If you have some translations of a given text laying around, each time you

+his/her work to make the translation up to date with regard to the current
+original text. Keep in mind that this task takes time, at least one week to get
+the update reviewed and all.
+ <p>
+If the translator is unresponsive, you may ask for help to the corresponding
+l10n mailing list. If everything fails, don't forget to put a warning in the
+translated document, stating that the translation is somehow outdated, and that
+the reader should refer to the original document if possible.

+ <p>
+The best solution is to fill a regular bug containing the translation against

+than 'wishlist', since the lack of translation never prevented a program from
+running.
+
+ <sect id="l10n-best">Best current practice concerning l10n
+ <p>
+<list>
+ <item>
+As a maintainer, never edit the translations in any way (even to reformat the
+layout) without asking to the corresponding l10n mailing list. You risk for
+example to break the encoding of the file by doing so. Moreover, what you
+consider as an error can be right (or even needed) in the given language.
+ <item>
+As a translator, if you find an error in the original text, make sure to report
+it. Translators are often the most attentive readers of a given text, and if
+they don't report the errors they find, nobody will.
+ <item>
+In any case, remember that the major issue with l10n is that it requires
+several people to cooperate, and that it is very easy to start a flamewar about
+small problems because of misunderstanding. So, if you have problems with your
+interlocutor, ask for help on the corresponding l10n mailing list, on
+debian-i18n, or even on debian-devel (but beware, l10n discussions very often
+become flamewars on that list :)
