-
-Once you have initialized an empty Git repository on your system
-(see @ref{Initializing a repository}), you can download a remote
-branch into it. Make sure you know which branch you want to start
-with.
-
-To download the @code{master} branch, enter the following:
-
-@example
-git remote add -ft master -m master \
- origin git://git.sv.gnu.org/lilypond.git/
-@end example
-
-To download the @code{translation} branch, enter:
-
-@example
-git remote add -ft translation -m \
- translation origin git://git.sv.gnu.org/lilypond.git/
-@end example
-
-The @command{git@tie{}remote@tie{}add} process could take up to
-ten minutes, depending on the speed of your connection. The
-output will be something like this:
-
-@example
-Updating origin
-remote: Counting objects: 235967, done.
-remote: Compressing objects: 100% (42721/42721), done.
-remote: Total 235967 (delta 195098), reused 233311 (delta 192772)

-@end example
-
-When @command{git@tie{}remote@tie{}add} is finished, the remote
-branch should be downloaded into your repository---though not yet
-in a form that you can use. In order to browse the source code
-files, you need to @emph{create} and @emph{checkout} your own
-local branch. In this case, however, it is easier to have Git
-create the branch automatically by using the @command{checkout}
-command on a non-existent branch. Enter the following:
-
-@example
-git checkout -b @var{branch} origin/@var{branch}
-@end example
-
-@noindent
-where @code{@var{branch}} is the name of your tracking branch,
-either @code{master} or @code{translation}.
-
-Git will issue some warnings; this is normal:
-
-@example
-warning: You appear to be on a branch yet to be born.
-warning: Forcing checkout of origin/master.
-Branch master set up to track remote branch master from origin.
-Already on 'master'
-@end example
-
-By now the source files should be accessible---you should be able
-to edit any files in the @file{$LILYPOND_GIT} directory using a
-text editor of your choice. But don't start just yet! Before
-editing any source files, learn how to keep your changes organized
-and prevent problems later---read @ref{Basic Git procedures}.
-
-@subsubheading Technical Details
-
-The @command{git@tie{}remote@tie{}add} command should add some
-lines to your local repository's @file{.git/config} file:
-
-@example
-[remote "origin"]
- url = git://git.sv.gnu.org/lilypond.git/
- fetch = +refs/heads/master:refs/remotes/origin/master
-@end example
-
-
-@node Downloading all remote branches
-@unnumberedsubsubsec Downloading all remote branches
-
-
-To download all remote branches at once, you can @command{clone}
-the entire repository:
-
-@example
-git clone git://git.sv.gnu.org/lilypond.git
-@end example
-
-

* Advanced Git concepts::
* Resolving conflicts::
* Reverting all local changes::
-* Working with remote branches::
* Git log::
* Applying remote patches::
* Sending and receiving patches via email::
referring to a branch, one often actually thinks about its head
and the ancestor commits of the head.
-Now we will explain the two last commands you used to get the
-source code from Git---see @ref{Downloading individual branches}.
-
-@example
-git remote add -ft @var{branch} -m @var{branch} \
- origin git://git.sv.gnu.org/lilypond.git/
-
-git checkout -b @var{branch} origin/@var{branch}
-@end example
-
-The @command{git@tie{}remote} has created a branch called
-@code{origin/@var{branch}} in your local Git repository. As this
-branch is a copy of the remote branch web from git.sv.gnu.org
-LilyPond repository, it is called a @emph{remote branch}, and is
-meant to track the changes on the branch from git.sv.gnu.org: it
-will be updated every time you run
-@command{git@tie{}pull@tie{}origin} or
-@command{git@tie{}fetch@tie{}origin}.
-
-The @command{git@tie{}checkout} command has created a branch named
-@code{@var{branch}}. At the beginning, this branch is identical
-to @code{origin/@var{branch}}, but it will differ as soon as you
-make changes, e.g. adding newly translated pages or editing some
-documentation or code source file. Whenever you pull, you merge
-the changes from @code{origin/@var{branch}} and
-@code{@var{branch}} since the last pulling. If you do not have
-push (i.e. @qq{write}) access on git.sv.gnu.org, your
-@code{@var{branch}} will always differ from
-@code{origin/@var{branch}}. In this case, remember that other
-people working like you with the remote branch @code{@var{branch}}
-of git://git.sv.gnu.org/lilypond.git/ (called
-@code{origin/@var{branch}} on your local repository) know nothing
-about your own @code{@var{branch}}: this means that whenever you
-use a committish or make a patch, others expect you to take the
-latest commit of @code{origin/@var{branch}} as a reference.
-
-Finally, please remember to read the man page of every Git command
-you will find in this manual in case you want to discover
-alternate methods or just understand how it works.

-@node Working with remote branches
-@subsection Working with remote branches
-
-
-@subsubheading Fetching new branches from git.sv.gnu.org
-
-To fetch and check out a new branch named @code{@var{branch}} on
-git.sv.gnu.org, run from top of the Git repository
-
-@example
-git config --add remote.origin.fetch \
- +refs/heads/@var{branch}:refs/remotes/origin/@var{branch}
-
-git checkout --track -b @var{branch} origin/@var{branch}
-@end example
-
-After this, you can pull @code{@var{branch}} from git.sv.gnu.org
-with:
-
-@example
-git pull
-@end example
-
-Note that this command generally fetches all branches you added
-with @command{git@tie{}remote@tie{}add} (when you initialized the
-repository) or @command{git@tie{}config@tie{}--add}, i.e. it
-updates all remote branches from remote @code{origin}, then it
-merges the remote branch tracked by the current branch into the
-current branch. For example, if your current branch is
-@code{master}, @code{origin/master} will be merged into
-@code{master}.
-
-
-@subsubheading Local clones, or having several working trees
-
-If you play with several Git branches, e.g. @code{master},
-@code{translation}, @code{stable/2.12}), you may want to
-have one source and build tree for each branch; this is possible
-with subdirectories of your local Git repository, used as local
-cloned subrepositories. To create a local clone for the branch
-named @code{@var{branch}}, run
-
-@example
-git checkout @var{branch}
-git clone -lsn . @var{subdir}
-cd @var{subdir}
-git reset --hard
-@end example
-
-Note that @code{@var{subdir}} must be a directory name which does
-not already exist. In @code{@var{subdir}}, you can use all Git
-commands to browse revisions history, commit and uncommit changes;
-to update the cloned subrepository with changes made on the main
-repository, cd into @code{@var{subdir}} and run
-@command{git@tie{}pull}; to send changes made on the subrepository
-back to the main repository, run @command{git@tie{}push} from
-@code{@var{subdir}}. Note that only one branch (the currently
-checked out branch) is created in the subrepository by default; it
-is possible to have several branches in a subrepository and do
-usual operations (checkout, merge, create, delete...) on these
-branches, but this possibility is not detailed here.
-
-When you push @code{@var{branch}} from @code{@var{subdir}} to the
-main repository, and @code{@var{branch}} is checked out in the
-main repository, you must save uncommitted changes (see
-@command{git@tie{}stash}) and do
-@command{git@tie{}reset@tie{}--hard} in the main repository in
-order to apply pushed changes in the working tree of the main
-repository.
