+GIT v1.6.5 Release Notes
+========================
+
+In git 1.7.0, which was planned to be the release after 1.6.5, "git
+push" into a branch that is currently checked out will be refused by
+default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyCurrentBranch in the receiving
+repository.
+
+Also, "git push $there :$killed" to delete the branch $killed in a remote
+repository $there, when $killed branch is the current branch pointed at by
+its HEAD, will be refused by default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyDeleteCurrent in the receiving
+repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing.  Please refer to:
+
+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+Updates since v1.6.4
+--------------------
+
+(subsystems)
+
+ * various updates to gitk, git-svn and gitweb.
+
+(portability)
+
+ * more improvements on mingw port.
+
+ * mingw will also give FRSX as the default value for the LESS
+   environment variable when the user does not have one.
+
+ * initial support to compile git on Windows with MSVC.
+
+(performance)
+
+ * On major platforms, the system can be compiled to use with Linus's
+   block-sha1 implementation of the SHA-1 hash algorithm, which
+   outperforms the default fallback implementation we borrowed from
+   Mozilla.
+
+ * Unnecessary inefficiency in deepening of a shallow repository has
+   been removed.
+
+ * "git clone" does not grab objects that it does not need (i.e.
+   referenced only from refs outside refs/heads and refs/tags
+   hierarchy) anymore.
+
+ * The "git" main binary used to link with libcurl, which then dragged
+   in a large number of external libraries.  When using basic plumbing
+   commands in scripts, this unnecessarily slowed things down.  We now
+   implement http/https/ftp transfer as a separate executable as we
+   used to.
+
+ * "git clone" run locally hardlinks or copies the files in .git/ to
+   newly created repository.  It used to give new mtime to copied files,
+   but this delayed garbage collection to trigger unnecessarily in the
+   cloned repository.  We now preserve mtime for these files to avoid
+   this issue.
+
+(usability, bells and whistles)
+
+ * Human writable date format to various options, e.g. --since=yesterday,
+   master@{2000.09.17}, are taught to infer some omitted input properly.
+
+ * A few programs gave verbose "advice" messages to help uninitiated
+   people when issuing error messages.  An infrastructure to allow
+   users to squelch them has been introduced, and a few such messages
+   can be silenced now.
+
+ * refs/replace/ hierarchy is designed to be usable as a replacement
+   of the "grafts" mechanism, with the added advantage that it can be
+   transferred across repositories.
+
+ * "git am" learned to optionally ignore whitespace differences.
+
+ * "git am" handles input e-mail files that has CRLF line endings sensibly.
+
+ * "git am" learned "--scissors" option to allow you to discard early part
+   of an incoming e-mail.
+
+ * "git archive -o output.zip" works without being told what format to
+   use with an explicit "--format=zip".option.
+
+ * "git checkout", "git reset" and "git stash" learned to pick and
+   choose to use selected changes you made, similar to "git add -p".
+
+ * "git clone" learned a "-b" option to pick a HEAD to check out
+   different from the remote's default branch.
+
+ * "git clone" learned --recursive option.
+
+ * "git clone" from a local repository on a different filesystem used to
+   copy individual object files without preserving the old timestamp, giving
+   them extra lifetime in the new repository until they gc'ed.
+
+ * "git commit --dry-run $args" is a new recommended way to ask "what would
+   happen if I try to commit with these arguments."
+
+ * "git commit --dry-run" and "git status" shows conflicted paths in a
+   separate section to make them easier to spot during a merge.
+
+ * "git cvsimport" now supports password-protected pserver access even
+   when the password is not taken from ~/.cvspass file.
+
+ * "git fast-export" learned --no-data option that can be useful when
+   reordering commits and trees without touching the contents of
+   blobs.
+
+ * "git fast-import" has a pair of new front-end in contrib/ area.
+
+ * "git init" learned to mkdir/chdir into a directory when given an
+   extra argument (i.e. "git init this").
+
+ * "git instaweb" optionally can use mongoose as the web server.
+
+ * "git log --decorate" can optionally be told with --decorate=full to
+   give the reference name in full.
+
+ * "git merge" issued an unnecessarily scary message when it detected
+   that the merge may have to touch the path that the user has local
+   uncommitted changes to. The message has been reworded to make it
+   clear that the command aborted, without doing any harm.
+
+ * "git push" can be told to be --quiet.
+
+ * "git push" pays attention to url.$base.pushInsteadOf and uses a URL
+   that is derived from the URL used for fetching.
+
+ * informational output from "git reset" that lists the locally modified
+   paths is made consistent with that of "git checkout $another_branch".
+
+ * "git submodule" learned to give submodule name to scripts run with
+   "foreach" subcommand.
+
+ * various subcommands to "git submodule" learned --recursive option.
+
+ * "git submodule summary" learned --files option to compare the work
+   tree vs the commit bound at submodule path, instead of comparing
+   the index.
+
+ * "git upload-pack", which is the server side support for "git clone" and
+   "git fetch", can call a new post-upload-pack hook for statistics purposes.
+
+(developers)
+
+ * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
+   source directory; using tmpfs may give faster turnaround.
+
+ * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
+   build for one location, and install into another location to tar it
+   up.
+
+Fixes since v1.6.4
+------------------
+
+All of the fixes in v1.6.4.X maintenance series are included in this
+release, unless otherwise noted.

+=====================
+
+NAME
+----
+git-remote-helpers - Helper programs for interoperation with remote git
+
+SYNOPSIS
+--------
+'git remote-<transport>' <remote>
+
+DESCRIPTION
+-----------
+
+These programs are normally not used directly by end users, but are
+invoked by various git programs that interact with remote repositories
+when the repository they would operate on will be accessed using
+transport code not linked into the main git binary. Various particular
+helper programs will behave as documented here.
+
+COMMANDS
+--------
+
+Commands are given by the caller on the helper's standard input, one per line.
+
+'capabilities'::
+	Lists the capabilities of the helper, one per line, ending
+	with a blank line.
+
+'list'::
+	Lists the refs, one per line, in the format "<value> <name>
+	[<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for
+	a symref, or "?" to indicate that the helper could not get the
+	value of the ref. A space-separated list of attributes follows
+	the name; unrecognized attributes are ignored. After the
+	complete list, outputs a blank line.
+
+'fetch' <sha1> <name>::
+	Fetches the given object, writing the necessary objects to the
+	database. Outputs a blank line when the fetch is
+	complete. Only objects which were reported in the ref list
+	with a sha1 may be fetched this way.
++
+Supported if the helper has the "fetch" capability.
+
+If a fatal error occurs, the program writes the error message to
+stderr and exits. The caller should expect that a suitable error
+message has been printed if the child closes the connection without
+completing a valid response for the current command.
+
+Additional commands may be supported, as may be determined from
+capabilities reported by the helper.
+
+CAPABILITIES
+------------
+
+'fetch'::
+	This helper supports the 'fetch' command.
+
+REF LIST ATTRIBUTES
+-------------------
+
+None are defined yet, but the caller must accept any which are supplied.

+NAME
+----
+git-replace - Create, list, delete refs to replace objects
+
+SYNOPSIS
+--------
+[verse]
+'git replace' [-f] <object> <replacement>
+'git replace' -d <object>...
+'git replace' -l [<pattern>]
+
+DESCRIPTION
+-----------
+Adds a 'replace' reference in `.git/refs/replace/`
+
+The name of the 'replace' reference is the SHA1 of the object that is
+replaced. The content of the replace reference is the SHA1 of the
+replacement object.
+
+Unless `-f` is given, the replace reference must not yet exist in
+`.git/refs/replace/` directory.
+
+OPTIONS
+-------
+-f::
+	If an existing replace ref for the same object exists, it will
+	be overwritten (instead of failing).
+
+-d::
+	Delete existing replace refs for the given objects.
+
+-l <pattern>::
+	List replace refs for objects that match the given pattern (or
+	all if no pattern is given).
+	Typing "git replace" without arguments, also lists all replace
+	refs.
+
+BUGS
+----
+Comparing blobs or trees that have been replaced with those that
+replace them will not work properly. And using 'git reset --hard' to
+go back to a replaced commit will move the branch to the replacement
+commit instead of the replaced commit.
+
+There may be other problems when using 'git rev-list' related to
+pending objects. And of course things may break if an object of one
+type is replaced by an object of another type (for example a blob
+replaced by a commit).

-Lists commit objects in reverse chronological order starting at the
-given commit(s), taking ancestry relationship into account.  This is
-useful to produce human-readable log output.
+List commits that are reachable by following the `parent` links from the
+given commit(s), but exclude commits that are reachable from the one(s)
+given with a '{caret}' in front of them.  The output is given in reverse
+chronological order by default.
 
-Commits which are stated with a preceding '{caret}' cause listing to

+You can think of this as a set operation.  Commits given on the command
+line form a set of commits that are reachable from any of them, and then
+commits reachable from any of the ones given with '{caret}' in front are
+subtracted from that set.  The remaining commits are what comes out in the
+command's output.  Various other options and paths parameters can be used
+to further limit the result.
+
+Thus, the following command:
 
 -----------------------------------------------------------------------
 	$ git rev-list foo bar ^baz

-means "list all the commits which are included in 'foo' and 'bar', but

+NAME
+----
+gittutorial - Um tutorial de introdução ao git (para versão 1.5.1 ou mais nova)
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+Este tutorial explica como importar um novo projeto para o git,
+adicionar mudanças a ele, e compartilhar mudanças com outros
+desenvolvedores.
+
+Se, ao invés disso, você está interessado primariamente em usar git para
+obter um projeto, por exemplo, para testar a última versão, você pode
+preferir começar com os primeiros dois capítulos de
+link:user-manual.html[O Manual do Usuário Git].
+
+Primeiro, note que você pode obter documentação para um comando como
+`git log --graph` com:
+
+------------------------------------------------
+$ man git-log
+------------------------------------------------
+
+ou:
+
+------------------------------------------------
+$ git help log
+------------------------------------------------
+
+Com a última forma, você pode usar o visualizador de manual de sua
+escolha; veja linkgit:git-help[1] para maior informação.
+
+É uma boa idéia informar ao git seu nome e endereço público de email
+antes de fazer qualquer operação. A maneira mais fácil de fazê-lo é:
+
+------------------------------------------------
+$ git config --global user.name "Seu Nome Vem Aqui"
+$ git config --global user.email voce@seudominio.exemplo.com
+------------------------------------------------
+
+
+Importando um novo projeto
+-----------------------
+
+Assuma que você tem um tarball project.tar.gz com seu trabalho inicial.
+Você pode colocá-lo sob controle de revisão git da seguinte forma:
+
+------------------------------------------------
+$ tar xzf project.tar.gz
+$ cd project
+$ git init
+------------------------------------------------
+
+Git irá responder
+
+------------------------------------------------
+Initialized empty Git repository in .git/
+------------------------------------------------
+
+Você agora iniciou seu diretório de trabalho--você deve ter notado um
+novo diretório criado, com o nome de ".git".
+
+A seguir, diga ao git para gravar um instantâneo do conteúdo de todos os
+arquivos sob o diretório corrente (note o '.'), com 'git-add':
+
+------------------------------------------------
+$ git add .
+------------------------------------------------
+
+Este instantâneo está agora armazenado em uma área temporária que o git
+chama de "index" ou índice. Você pode armazenar permanentemente o
+conteúdo do índice no repositório com 'git-commit':
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+Isto vai te pedir por uma mensagem de commit. Você agora gravou sua
+primeira versão de seu projeto no git.
+
+Fazendo mudanças
+--------------
+
+Modifique alguns arquivos, e, então, adicione seu conteúdo atualizado ao
+índice:
+
+------------------------------------------------
+$ git add file1 file2 file3
+------------------------------------------------
+
+Você está agora pronto para fazer o commit. Você pode ver o que está
+para ser gravado usando 'git-diff' com a opção --cached:
+
+------------------------------------------------
+$ git diff --cached
+------------------------------------------------
+
+(Sem --cached, o comando 'git-diff' irá te mostrar quaisquer mudanças
+que você tenha feito mas ainda não adicionou ao índice.) Você também
+pode obter um breve sumário da situação com 'git-status':
+
+------------------------------------------------
+$ git status
+# On branch master
+# Changes to be committed:
+#   (use "git reset HEAD <file>..." to unstage)
+#
+#	modified:   file1
+#	modified:   file2
+#	modified:   file3
+#
+------------------------------------------------
+
+Se você precisar fazer qualquer outro ajuste, faça-o agora, e, então,
+adicione qualquer conteúdo modificado ao índice. Finalmente, grave suas
+mudanças com:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+Isto irá novamente te pedir por uma mensagem descrevendo a mudança, e,
+então, gravar a nova versão do projeto.
+
+Alternativamente, ao invés de executar 'git-add' antes, você pode usar
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+o que irá automaticamente notar quaisquer arquivos modificados (mas não
+novos), adicioná-los ao índices, e gravar, tudo em um único passo.
+
+Uma nota em mensagens de commit: Apesar de não ser exigido, é uma boa
+idéia começar a mensagem com uma simples e curta (menos de 50
+caracteres) linha sumarizando a mudança, seguida de uma linha em branco
+e, então, uma descrição mais detalhada. Ferramentas que transformam
+commits em email, por exemplo, usam a primeira linha no campo de
+cabeçalho Subject: e o resto no corpo.
+
+Git rastreia conteúdo, não arquivos
+----------------------------
+
+Muitos sistemas de controle de revisão provêem um comando `add` que diz
+ao sistema para começar a rastrear mudanças em um novo arquivo. O
+comando `add` do git faz algo mais simples e mais poderoso: 'git-add' é
+usado tanto para arquivos novos e arquivos recentemente modificados, e
+em ambos os casos, ele tira o instantâneo dos arquivos dados e armazena
+o conteúdo no índice, pronto para inclusão do próximo commit.
+
+Visualizando história do projeto
+-----------------------
+
+Em qualquer ponto você pode visualizar a história das suas mudanças
+usando
+
+------------------------------------------------
+$ git log
+------------------------------------------------
+
+Se você também quer ver a diferença completa a cada passo, use
+
+------------------------------------------------
+$ git log -p
+------------------------------------------------
+
+Geralmente, uma visão geral da mudança é útil para ter a sensação de
+cada passo
+
+------------------------------------------------
+$ git log --stat --summary
+------------------------------------------------
+
+Gerenciando "branches"/ramos
+-----------------
+
+Um simples repositório git pode manter múltiplos ramos de
+desenvolvimento. Para criar um novo ramo chamado "experimental", use
+
+------------------------------------------------
+$ git branch experimental
+------------------------------------------------
+
+Se você executar agora
+
+------------------------------------------------
+$ git branch
+------------------------------------------------
+
+você vai obter uma lista de todos os ramos existentes:
+
+------------------------------------------------
+  experimental
+* master
+------------------------------------------------
+
+O ramo "experimental" é o que você acaba de criar, e o ramo "master" é o
+ramo padrão que foi criado pra você automaticamente. O asterisco marca
+o ramo em que você está atualmente; digite
+
+------------------------------------------------
+$ git checkout experimental
+------------------------------------------------
+
+para mudar para o ramo experimental. Agora edite um arquivo, grave a
+mudança, e mude de volta para o ramo master:
+
+------------------------------------------------
+(edita arquivo)
+$ git commit -a
+$ git checkout master
+------------------------------------------------
+
+Verifique que a mudança que você fez não está mais visível, já que ela
+foi feita no ramo experimental e você está de volta ao ramo master.
+
+Você pode fazer uma mudança diferente no ramo master:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+------------------------------------------------
+
+neste ponto, os dois ramos divergiram, com diferentes mudanças feitas em
+cada um. Para unificar as mudanças feitas no experimental para o
+master, execute
+
+------------------------------------------------
+$ git merge experimental
+------------------------------------------------
+
+Se as mudanças não conflitarem, estará pronto. Se existirem conflitos,
+marcadores serão deixados nos arquivos problemáticos exibindo o
+conflito;
+
+------------------------------------------------
+$ git diff
+------------------------------------------------
+
+vai exibir isto. Após você editar os arquivos para resolver os
+conflitos,
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+irá gravar o resultado da unificação. Finalmente,
+
+------------------------------------------------
+$ gitk
+------------------------------------------------
+
+vai mostrar uma bela representação gráfica da história resultante.
+
+Neste ponto você pode remover seu ramo experimental com
+
+------------------------------------------------
+$ git branch -d experimental
+------------------------------------------------
+
+Este comando garante que as mudanças no ramo experimental já estão no
+ramo atual.
+
+Se você desenvolve em um ramo ideia-louca, e se arrepende, você pode
+sempre remover o ramo com
+
+-------------------------------------
+$ git branch -D ideia-louca
+-------------------------------------
+
+Ramos são baratos e fáceis, então isto é uma boa maneira de experimentar
+alguma coisa.
+
+Usando git para colaboração
+---------------------------
+
+Suponha que Alice começou um novo projeto com um repositório git em
+/home/alice/project, e que Bob, que tem um diretório home na mesma
+máquina, quer contribuir.
+
+Bob começa com:
+
+------------------------------------------------
+bob$ git clone /home/alice/project myrepo
+------------------------------------------------
+
+Isso cria um novo diretório "myrepo" contendo um clone do repositório de
+Alice. O clone está no mesmo pé que o projeto original, possuindo sua
+própria cópia da história do projeto original.
+
+Bob então faz algumas mudanças e as grava:
+
+------------------------------------------------
+(editar arquivos)
+bob$ git commit -a
+(repetir conforme necessário)
+------------------------------------------------
+
+Quanto está pronto, ele diz a Alice para puxar as mudanças do
+repositório em /home/bob/myrepo. Ela o faz com:
+
+------------------------------------------------
+alice$ cd /home/alice/project
+alice$ git pull /home/bob/myrepo master
+------------------------------------------------
+
+Isto unifica as mudanças do ramo "master" do Bob ao ramo atual de Alice.
+Se Alice fez suas próprias mudanças no intervalo, ela, então, pode
+precisar corrigir manualmente quaisquer conflitos. (Note que o argumento
+"master" no comando acima é, de fato, desnecessário, já que é o padrão.)
+
+O comando "pull" executa, então, duas operações: ele obtém mudanças de
+um ramo remoto, e, então, as unifica no ramo atual.
+
+Note que, em geral, Alice gostaria que suas mudanças locais fossem
+gravadas antes de iniciar este "pull". Se o trabalho de Bob conflita
+com o que Alice fez desde que suas histórias se ramificaram, Alice irá
+usar seu diretório de trabalho e o índice para resolver conflitos, e
+mudanças locais existentes irão interferir com o processo de resolução
+de conflitos (git ainda irá realizar a obtenção mas irá se recusar a
+unificar --- Alice terá que se livrar de suas mudanças locais de alguma
+forma e puxar de novo quando isso acontecer).
+
+Alice pode espiar o que Bob fez sem unificar primeiro, usando o comando
+"fetch"; isto permite Alice inspecionar o que Bob fez, usando um símbolo
+especial "FETCH_HEAD", com o fim de determinar se ele tem alguma coisa
+que vale puxar, assim:
+
+------------------------------------------------
+alice$ git fetch /home/bob/myrepo master
+alice$ git log -p HEAD..FETCH_HEAD
+------------------------------------------------
+
+Esta operação é segura mesmo se Alice tem mudanças locais não gravadas.
+A notação de intervalo "HEAD..FETCH_HEAD" significa mostrar tudo que é
+alcançável de FETCH_HEAD mas exclua tudo o que é alcançável de HEAD.
+Alice já sabe tudo que leva a seu estado atual (HEAD), e revisa o que Bob
+tem em seu estado (FETCH_HEAD) que ela ainda não viu com esse comando.
+
+Se Alice quer visualizar o que Bob fez desde que suas histórias se
+ramificaram, ela pode disparar o seguinte comando:
+
+------------------------------------------------
+$ gitk HEAD..FETCH_HEAD
+------------------------------------------------
+
+Isto usa a mesma notação de intervalo que vimos antes com 'git log'.
+
+Alice pode querer ver o que ambos fizeram desde que ramificaram. Ela
+pode usar a forma com três pontos ao invés da forma com dois pontos:
+
+------------------------------------------------
+$ gitk HEAD...FETCH_HEAD
+------------------------------------------------
+
+Isto significa "mostre tudo que é alcançável de qualquer um deles, mas
+exclua tudo que é alcançável a partir de ambos".
+
+Por favor, note que essas notações de intervalo podem ser usadas tanto
+com gitk quanto com "git log".
+
+Após inspecionar o que Bob fez, se não há nada urgente, Alice pode
+decidir continuar trabalhando sem puxar de Bob. Se a história de Bob
+tem alguma coisa que Alice precisa imediatamente, Alice pode optar por
+separar seu trabalho em progresso primeiro, fazer um "pull", e, então,
+finalmente, retomar seu trabalho em progresso em cima da história
+resultante.
+
+Quando você está trabalhando em um pequeno grupo unido, não é incomum
+interagir com o mesmo repositório várias e várias vezes. Definindo um
+repositório remoto antes de tudo, você pode fazê-lo mais facilmente:
+
+------------------------------------------------
+alice$ git remote add bob /home/bob/myrepo
+------------------------------------------------
+
+Com isso, Alice pode executar a primeira parte da operação "pull" usando
+o comando 'git-fetch' sem unificar suas mudanças com seu próprio ramo,
+usando:
+
+-------------------------------------
+alice$ git fetch bob
+-------------------------------------
+
+Diferente da forma longa, quando Alice obteve de Bob usando um
+repositório remoto antes definido com 'git-remote', o que foi obtido é
+armazenado em um ramo remoto, neste caso `bob/master`. Então, após isso:
+
+-------------------------------------
+alice$ git log -p master..bob/master
+-------------------------------------
+
+mostra uma lista de todas as mudanças que Bob fez desde que ramificou do
+ramo master de Alice.
+
+Após examinar essas mudanças, Alice pode unificá-las em seu ramo master:
+
+-------------------------------------
+alice$ git merge bob/master
+-------------------------------------
+
+Esse `merge` pode também ser feito puxando de seu próprio ramo remoto,
+assim:
+
+-------------------------------------
+alice$ git pull . remotes/bob/master
+-------------------------------------
+
+Note que 'git pull' sempre unifica ao ramo atual, independente do que
+mais foi passado na linha de comando.
+
+Depois, Bob pode atualizar seu repositório com as últimas mudanças de
+Alice, usando
+
+-------------------------------------
+bob$ git pull
+-------------------------------------
+
+Note que ele não precisa dar o caminho do repositório de Alice; quando
+Bob clonou seu repositório, o git armazenou a localização de seu
+repositório na configuração do mesmo, e essa localização é usada
+para puxar:
+
+-------------------------------------
+bob$ git config --get remote.origin.url
+/home/alice/project
+-------------------------------------
+
+(A configuração completa criada por 'git-clone' é visível usando `git
+config -l`, e a página de manual linkgit:git-config[1] explica o
+significado de cada opção.)
+
+Git também mantém uma cópia limpa do ramo master de Alice sob o nome
+"origin/master":
+
+-------------------------------------
+bob$ git branch -r
+  origin/master
+-------------------------------------
+
+Se Bob decidir depois em trabalhar em um host diferente, ele ainda pode
+executar clones e puxar usando o protocolo ssh:
+
+-------------------------------------
+bob$ git clone alice.org:/home/alice/project myrepo
+-------------------------------------
+
+Alternativamente, o git tem um protocolo nativo, ou pode usar rsync ou
+http; veja linkgit:git-pull[1] para detalhes.
+
+Git pode também ser usado em um modo parecido com CVS, com um
+repositório central para o qual vários usuários empurram modificações;
+veja linkgit:git-push[1] e linkgit:gitcvs-migration[7].
+
+Explorando história
+-----------------
+
+A história no git é representada como uma série de commits
+interrelacionados. Nós já vimos que o comando 'git-log' pode listar
+esses commits. Note que a primeira linha de cada entrada no log também
+dá o nome para o commit:
+
+-------------------------------------
+$ git log
+commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+Author: Junio C Hamano <junkio@cox.net>
+Date:   Tue May 16 17:18:22 2006 -0700
+
+    merge-base: Clarify the comments on post processing.
+-------------------------------------
+
+Nós podemos dar este nome ao 'git-show' para ver os detalhes sobre este
+commit.
+
+-------------------------------------
+$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+-------------------------------------
+
+Mas há outras formas de se referir aos commits. Você pode usar qualquer
+parte inicial do nome que seja longo o bastante para identificar
+unicamente o commit:
+
+-------------------------------------
+$ git show c82a22c39c	# os primeiros caracteres do nome são o bastante
+			# usualmente
+$ git show HEAD		# a ponta do ramo atual
+$ git show experimental	# a ponta do ramo "experimental"
+-------------------------------------
+
+Todo commit normalmente tem um commit "pai" que aponta para o estado
+anterior do projeto:
+
+-------------------------------------
+$ git show HEAD^  # para ver o pai de HEAD
+$ git show HEAD^^ # para ver o avô de HEAD
+$ git show HEAD~4 # para ver o trisavô de HEAD
+-------------------------------------
+
+Note que commits de unificação podem ter mais de um pai:
+
+-------------------------------------
+$ git show HEAD^1 # mostra o primeiro pai de HEAD (o mesmo que HEAD^)
+$ git show HEAD^2 # mostra o segundo pai de HEAD
+-------------------------------------
+
+Você também pode dar aos commits nomes à sua escolha; após executar
+
+-------------------------------------
+$ git tag v2.5 1b2e1d63ff
+-------------------------------------
+
+você pode se referir a 1b2e1d63ff pelo nome "v2.5". Se você pretende
+compartilhar esse nome com outras pessoas (por exemplo, para identificar
+uma versão de lançamento), você deveria criar um objeto "tag", e talvez
+assiná-lo; veja linkgit:git-tag[1] para detalhes.
+
+Qualquer comando git que precise conhecer um commit pode receber
+quaisquer desses nomes. Por exemplo:
+
+-------------------------------------
+$ git diff v2.5 HEAD	 # compara o HEAD atual com v2.5
+$ git branch stable v2.5 # inicia um novo ramo chamado "stable" baseado
+			 # em v2.5
+$ git reset --hard HEAD^ # reseta seu ramo atual e seu diretório de
+			 # trabalho a seu estado em HEAD^
+-------------------------------------
+
+Seja cuidadoso com o último comando: além de perder quaisquer mudanças
+em seu diretório de trabalho, ele também remove todos os commits
+posteriores desse ramo. Se esse ramo é o único ramo contendo esses
+commits, eles serão perdidos. Também, não use 'git-reset' num ramo
+publicamente visível de onde outros desenvolvedores puxam, já que vai
+forçar unificações desnecessárias para que outros desenvolvedores limpem
+a história. Se você precisa desfazer mudanças que você empurrou, use
+'git-revert' no lugar.
+
+O comando 'git-grep' pode buscar strings em qualquer versão de seu
+projeto, então
+
+-------------------------------------
+$ git grep "hello" v2.5
+-------------------------------------
+
+procura por todas as ocorrências de "hello" em v2.5.
+
+Se você deixar de fora o nome do commit, 'git-grep' irá procurar
+quaisquer dos arquivos que ele gerencia no diretório corrente. Então
+
+-------------------------------------
+$ git grep "hello"
+-------------------------------------
+
+é uma forma rápida de buscar somente os arquivos que são rastreados pelo
+git.
+
+Muitos comandos git também recebem um conjunto de commits, o que pode
+ser especificado de várias formas. Aqui estão alguns exemplos com 'git-log':
+
+-------------------------------------
+$ git log v2.5..v2.6            # commits entre v2.5 e v2.6
+$ git log v2.5..                # commits desde v2.5
+$ git log --since="2 weeks ago" # commits das últimas 2 semanas
+$ git log v2.5.. Makefile       # commits desde v2.5 que modificam
+				# Makefile
+-------------------------------------
+
+Você também pode dar ao 'git-log' um "intervalo" de commits onde o
+primeiro não é necessariamente um ancestral do segundo; por exemplo, se
+as pontas dos ramos "stable" e "master" divergiram de um commit
+comum algum tempo atrás, então
+
+-------------------------------------
+$ git log stable..master
+-------------------------------------
+
+irá listar os commits feitos no ramo "master" mas não no ramo
+"stable", enquanto
+
+-------------------------------------
+$ git log master..stable
+-------------------------------------
+
+irá listar a lista de commits feitos no ramo "stable" mas não no ramo
+"master".
+
+O comando 'git-log' tem uma fraqueza: ele precisa mostrar os commits em
+uma lista. Quando a história tem linhas de desenvolvimento que
+divergiram e então foram unificadas novamente, a ordem em que 'git-log'
+apresenta essas mudanças é irrelevante.
+
+A maioria dos projetos com múltiplos contribuidores (como o kernel
+Linux, ou o próprio git) tem unificações frequentes, e 'gitk' faz um
+trabalho melhor de visualizar sua história. Por exemplo,
+
+-------------------------------------
+$ gitk --since="2 weeks ago" drivers/
+-------------------------------------
+
+permite a você navegar em quaisquer commits desde as últimas duas semanas
+de commits que modificaram arquivos sob o diretório "drivers". (Nota:
+você pode ajustar as fontes do gitk segurando a tecla control enquanto
+pressiona "-" ou "+".)
+
+Finalmente, a maioria dos comandos que recebem nomes de arquivo permitirão
+também, opcionalmente, preceder qualquer nome de arquivo por um
+commit, para especificar uma versão particular do arquivo:
+
+-------------------------------------
+$ git diff v2.5:Makefile HEAD:Makefile.in
+-------------------------------------
+
+Você pode usar 'git-show' para ver tal arquivo:
+
+-------------------------------------
+$ git show v2.5:Makefile
+-------------------------------------
+
+Próximos passos
+----------
+
+Este tutorial deve ser o bastante para operar controle de revisão
+distribuído básico para seus projetos. No entanto, para entender
+plenamente a profundidade e o poder do git você precisa entender duas
+idéias simples nas quais ele se baseia:
+
+  * A base de objetos é um sistema bem elegante usado para armazenar a
+    história de seu projeto--arquivos, diretórios, e commits.
+
+  * O arquivo de índice é um cache do estado de uma árvore de diretório,
+    usado para criar commits, restaurar diretórios de trabalho, e
+    armazenar as várias árvores envolvidas em uma unificação.
+
+A parte dois deste tutorial explica a base de objetos, o arquivo de
+índice, e algumas outras coisinhas que você vai precisar pra usar o
+máximo do git. Você pode encontrá-la em linkgit:gittutorial-2[7].
+
+Se você não quiser continuar com o tutorial agora nesse momento, algumas
+outras digressões que podem ser interessantes neste ponto são:
+
+  * linkgit:git-format-patch[1], linkgit:git-am[1]: Estes convertem
+    séries de commits em patches para email, e vice-versa, úteis para
+    projetos como o kernel Linux que dependem fortemente de patches
+    enviados por email.
+
+  * linkgit:git-bisect[1]: Quando há uma regressão em seu projeto, uma
+    forma de rastrear um bug é procurando pela história para encontrar o
+    commit culpado. Git bisect pode ajudar a executar uma busca binária
+    por esse commit. Ele é inteligente o bastante para executar uma
+    busca próxima da ótima mesmo no caso de uma história complexa
+    não-linear com muitos ramos unificados.

 tree walking API
 ================
 
-Talk about <tree-walk.h>, things like
+The tree walking API is used to traverse and inspect trees.
 
-* struct tree_desc
-* init_tree_desc
-* tree_entry_extract
-* update_tree_entry
-* get_tree_entry
+Data Structures
+---------------
 
-(JC, Linus)
+`struct name_entry`::
+
+	An entry in a tree. Each entry has a sha1 identifier, pathname, and
+	mode.
+
+`struct tree_desc`::
+
+	A semi-opaque data structure used to maintain the current state of the
+	walk.
++
+* `buffer` is a pointer into the memory representation of the tree. It always
+points at the current entry being visited.
+
+* `size` counts the number of bytes left in the `buffer`.
+
+* `entry` points to the current entry being visited.
+
+`struct traverse_info`::
+
+	A structure used to maintain the state of a traversal.
++
+* `prev` points to the traverse_info which was used to descend into the
+current tree. If this is the top-level tree `prev` will point to
+a dummy traverse_info.
+
+* `name` is the entry for the current tree (if the tree is a subtree).
+
+* `pathlen` is the length of the full path for the current tree.
+
+* `conflicts` can be used by callbacks to maintain directory-file conflicts.
+
+* `fn` is a callback called for each entry in the tree. See Traversing for more
+information.
+
+* `data` can be anything the `fn` callback would want to use.
+
+Initializing
+------------
+
+`init_tree_desc`::
+
+	Initialize a `tree_desc` and decode its first entry. The buffer and
+	size parameters are assumed to be the same as the buffer and size
+	members of `struct tree`.
+
+`fill_tree_descriptor`::
+
+	Initialize a `tree_desc` and decode its first entry given the sha1 of
+	a tree. Returns the `buffer` member if the sha1 is a valid tree
+	identifier and NULL otherwise.
+
+`setup_traverse_info`::
+
+	Initialize a `traverse_info` given the pathname of the tree to start
+	traversing from. The `base` argument is assumed to be the `path`
+	member of the `name_entry` being recursed into unless the tree is a
+	top-level tree in which case the empty string ("") is used.
+
+Walking
+-------
+
+`tree_entry`::
+
+	Visit the next entry in a tree. Returns 1 when there are more entries
+	left to visit and 0 when all entries have been visited. This is
+	commonly used in the test of a while loop.
+
+`tree_entry_len`::
+
+	Calculate the length of a tree entry's pathname. This utilizes the
+	memory structure of a tree entry to avoid the overhead of using a
+	generic strlen().
+
+`update_tree_entry`::
+
+	Walk to the next entry in a tree. This is commonly used in conjunction
+	with `tree_entry_extract` to inspect the current entry.
+
+`tree_entry_extract`::
+
+	Decode the entry currently being visited (the one pointed to by
+	`tree_desc's` `entry` member) and return the sha1 of the entry. The
+	`pathp` and `modep` arguments are set to the entry's pathname and mode
+	respectively.
+
+`get_tree_entry`::
+
+	Find an entry in a tree given a pathname and the sha1 of a tree to
+	search. Returns 0 if the entry is found and -1 otherwise. The third
+	and fourth parameters are set to the entry's sha1 and mode
+	respectively.
+
+Traversing
+----------
+
+`traverse_trees`::
+
+	Traverse `n` number of trees in parallel. The `fn` callback member of
+	`traverse_info` is called once for each tree entry.
+
+`traverse_callback_t`::
+	The arguments passed to the traverse callback are as follows:
++
+* `n` counts the number of trees being traversed.
+
+* `mask` has its nth bit set if something exists in the nth entry.
+
+* `dirmask` has its nth bit set if the nth tree's entry is a directory.
+
+* `entry` is an array of size `n` where the nth entry is from the nth tree.
+
+* `info` maintains the state of the traversal.
+
++
+Returning a negative value will terminate the traversal. Otherwise the
+return value is treated as an update mask. If the nth bit is set the nth tree
+will be updated and if the bit is not set the nth tree entry will be the
+same in the next callback invocation.
+
+`make_traverse_path`::
+
+	Generate the full pathname of a tree entry based from the root of the
+	traversal. For example, if the traversal has recursed into another
+	tree named "bar" the pathname of an entry "baz" in the "bar"
+	tree would be "bar/baz".
+
+`traverse_path_len`::
+
+	Calculate the length of a pathname returned by `make_traverse_path`.
+	This utilizes the memory structure of a tree entry to avoid the
+	overhead of using a generic strlen().

+The Steps of Build Git with VS2008
+
+1. You need the build environment, which contains the Git dependencies
+   to be able to compile, link and run Git with MSVC.
+
+   You can either use the binary repository:
+
+       WWW: http://repo.or.cz/w/msvcgit.git
+       Git: git clone git://repo.or.cz/msvcgit.git
+       Zip: http://repo.or.cz/w/msvcgit.git?a=snapshot;h=master;sf=zip
+
+   and call the setup_32bit_env.cmd batch script before compiling Git,
+   (see repo/package README for details), or the source repository:
+
+       WWW: http://repo.or.cz/w/gitbuild.git
+       Git: git clone git://repo.or.cz/gitbuild.git
+       Zip: (None, as it's a project with submodules)
+
+   and build the support libs as instructed in that repo/package.
+
+2. Ensure you have the msysgit environment in your path, so you have
+   GNU Make, bash and perl available.
+
+       WWW: http://repo.or.cz/w/msysgit.git
+       Git: git clone git://repo.or.cz/msysgit.git
+       Zip: http://repo.or.cz/w/msysgit.git?a=snapshot;h=master;sf=zip
+
+   This environment is also needed when you use the resulting
+   executables, since Git might need to run scripts which are part of
+   the git operations.
+
+3. Inside Git's directory run the command:
+       make common-cmds.h
+   to generate the common-cmds.h file needed to compile git.
+
+4. Then either build Git with the GNU Make Makefile in the Git projects
+   root
+       make MSVC=1
+   or generate Visual Studio solution/projects (.sln/.vcproj) with the
+   command
+       perl contrib/buildsystems/generate -g Vcproj
+   and open and build the solution with the IDE
+       devenv git.sln /useenv
+   or build with the IDE build engine directly from the command line
+       devenv git.sln /useenv /build "Release|Win32"
+   The /useenv option is required, so Visual Studio picks up the
+   environment variables for the support libraries required to build
+   Git, which you set up in step 1.
+
+Done!

+=head1 NAME
+
+import-directories - Import bits and pieces to Git.
+
+=head1 SYNOPSIS
+
+B<import-directories.perl> F<configfile> F<outputfile>
+
+=head1 DESCRIPTION
+
+Script to import arbitrary projects version controlled by the "copy the
+source directory to a new location and edit it there"-version controlled
+projects into version control. Handles projects with arbitrary branching
+and version trees, taking a file describing the inputs and generating a
+file compatible with the L<git-fast-import(1)> format.
+
+=head1 CONFIGURATION FILE
+
+=head2 Format
+
+The configuration file is based on the standard I<.ini> format.
+
+ ; Comments start with semi-colons
+ [section]
+ key=value
+
+Please see below for information on how to escape special characters.
+
+=head2 Global configuration
+
+Global configuration is done in the B<[config]> section, which should be
+the first section in the file. Configuration can be changed by
+repeating configuration sections later on.
+
+ [config]
+ ; configure conversion of CRLFs. "convert" means that all CRLFs
+ ; should be converted into LFs (suitable for the core.autocrlf
+ ; setting set to true in Git). "none" means that all data is
+ ; treated as binary.
+ crlf=convert
+
+=head2 Revision configuration
+
+Each revision that is to be imported is described in three
+sections. Revisions should be defined in topological order, so
+that a revision's parent has always been defined when a new revision
+is introduced. All the sections for one revision must be defined
+before defining the next revision.
+
+Each revision is assigned a unique numerical identifier. The
+numbers do not need to be consecutive, nor monotonically
+increasing.
+
+For instance, if your configuration file contains only the two
+revisions 4711 and 42, where 4711 is the initial commit, the
+only requirement is that 4711 is completely defined before 42.
+
+=pod
+
+=head3 Revision description section
+
+A section whose section name is just an integer gives meta-data
+about the revision.
+
+ [3]
+ ; author sets the author of the revisions
+ author=Peter Krefting <peter@softwolves.pp.se>
+ ; branch sets the branch that the revision should be committed to
+ branch=master
+ ; parent describes the revision that is the parent of this commit
+ ; (optional)
+ parent=1
+ ; merges describes a revision that is merged into this commit
+ ; (optional; can be repeated)
+ merges=2
+ ; selects one file to take the timestamp from
+ ; (optional; if unspecified, the most recent file from the .files
+ ;  section is used)
+ timestamp=3/source.c
+
+=head3 Revision contents section
+
+A section whose section name is an integer followed by B<.files>
+describe all the files included in this revision. If a file that
+was available previously is not included in this revision, it will
+be removed.
+
+If an on-disk revision is incomplete, you can point to files from
+a previous revision. There are no restriction as to where the source
+files are located, nor to the names of them.
+
+ [3.files]
+ ; the key is the path inside the repository, the value is the path
+ ; as seen from the importer script.
+ source.c=ver-3.00/source.c
+ source.h=ver-2.99/source.h
+ readme.txt=ver-3.00/introduction to the project.txt
+
+File names are treated as byte strings (but please see below on
+quoting rules), and should be stored in the configuration file in
+the encoding that should be used in the generated repository.
+
+=head3 Revision commit message section
+
+A section whose section name is an integer followed by B<.message>
+gives the commit message. This section is read verbatim, up until
+the beginning of the next section. As such, a commit message may not
+contain a line that begins with an opening square bracket ("[") and
+ends with a closing square bracket ("]"), unless they are surrounded
+by whitespace or other characters.
+
+ [3.message]
+ Implement foobar.
+ ; trailing blank lines are ignored.

+=head2 Escaping special characters
+
+Key and value strings may be enclosed in quotes, in which case
+whitespace inside the quotes is preserved. Additionally, an equal
+sign may be included in the key by preceeding it with a backslash.
+For example:
+
+ "key1 "=value1
+ key2=" value2"
+ key\=3=value3
+ key4=value=4
+ "key5""=value5
+
+Here the first key is "key1 " (note the trailing white-space) and the
+second value is " value2" (note the leading white-space). The third
+key contains an equal sign "key=3" and so does the fourth value, which
+does not need to be escaped. The fifth key contains a trailing quote,
+which does not need to be escaped since it is inside a surrounding
+quote.
+
+=cut
+	my $pair = shift;
+
+	# Separate key and value by the first non-quoted equal sign
+	my ($key, $value);
+	if ($pair =~ /^(.*[^\\])=(.*)$/)
+	{
+		($key, $value) = ($1, $2)
+	}
+	else
+	{
+		die "Parse error: $pair\n ";
+	}
+
+	# Unquote and unescape the key and value separately
+	return (&unescape($key), &unescape($value));
+}
+
+# Unquote and unescape
+sub unescape
+{
+	my $string = shift;
+
+	# First remove enclosing quotes. Backslash before the trailing
+	# quote leaves both.
+	if ($string =~ /^"(.*[^\\])"$/)
+	{
+		$string = $1;
+	}
+
+	# Second remove any backslashes inside the unquoted string.
+	# For later: Handle special sequences like \t ?

+This repository is for testing the ability to group revisions
+correctly along tags and branches.  Here is its history:
+
+  1.  The initial import (revision 1.1 of everybody) created a
+      directory structure with a file named `default' in each dir:
+
+            ./
+              default
+              sub1/default
+                   subsubA/default
+                   subsubB/default
+              sub2/default
+                   subsubA/default
+              sub3/default
+
+  2.  Then tagged everyone with T_ALL_INITIAL_FILES.
+
+  3.  Then tagged everyone except sub1/subsubB/default with
+      T_ALL_INITIAL_FILES_BUT_ONE.
+
+  4.  Then created branch B_FROM_INITIALS on everyone.
+
+  5.  Then created branch B_FROM_INITIALS_BUT_ONE on everyone except
+      /sub1/subsubB/default.
+
+  6.  Then committed modifications to two files: sub3/default, and
+      sub1/subsubA/default.
+
+  7.  Then committed a modification to all 7 files.
+
+  8.  Then backdated sub3/default to revision 1.2, and
+      sub2/subsubA/default to revision 1.1, and tagged with T_MIXED.
+
+  9.  Same as 8, but tagged with -b to create branch B_MIXED.
+
+  10. Switched the working copy to B_MIXED, and added
+      sub2/branch_B_MIXED_only.  (That's why the RCS file is in
+      sub2/Attic/ -- it never existed on trunk.)
+
+  11. In one commit, modified default, sub1/default, and
+      sub2/subsubA/default, on branch B_MIXED.
+
+  12. Did "cvs up -A" on sub2/default, then in one commit, made a
+      change to sub2/default and sub2/branch_B_MIXED_only.  So this
+      commit should be spread between the branch and the trunk.
+
+  13. Do "cvs up -A" to get everyone back to trunk, then make a new
+      branch B_SPLIT on everyone except sub1/subsubB/default,v.
+
+  14. Switch to branch B_SPLIT (see sub1/subsubB/default disappear)
+      and commit a change that affects everyone except sub3/default.
+
+  15. An hour or so later, "cvs up -A" to get sub1/subsubB/default
+      back, then commit a change on that file, on trunk.  (It's
+      important that this change happened after the previous commits
+      on B_SPLIT.)
+
+  16. Branch sub1/subsubB/default to B_SPLIT, then "cvs up -r B_SPLIT"
+      to switch the whole working copy to the branch.
+
+  17. Commit a change on B_SPLIT, to sub1/subsubB/default and
+      sub3/default.
