+The sources live in a GIT repository. Git 1.5.x is required, and
+latest version available on your platform is always recommended. To

- mkdir lily ; cd lily
- git init-db
- git fetch git://git.sv.gnu.org/lilypond.git/ refs/heads/lilypond/translation:lilypond/translation

+
+then run
+
+ git fetch trans
+ git checkout -b lilypond/translation origin/lilypond/translation
GIT
This command is mainly intended to be used by the Translation meister.
+MISCELLANEOUS: DEALING WITH SEVERAL GIT BRANCHES
+
+* It is possible to work with several branches on the same local Git
+repository; this is especially useful for translators who may have to
+deal with both lilypond/translation and a stable branch
+(e.g. stable/2.12 or lilypond/translation-2.12). To fetch and check
+out a new branch named BRANCH on git.sv.gnu.org, write the two
+following lines to a text file named .git/remotes/SHORTHAND --
+SHORTHAND is the name of the remote file, i.e. whatever easy-to-type
+name you would like to use when pulling or pushing BRANCH, and usually
+SHORTHAND is an abbreviation of BRANCH without slashes
+
+URL: git://git.sv.gnu.org/lilypond.git/
+Pull: BRANCH:refs/remotes/origin/BRANCH
+
+Then, run
+
+ git fetch SHORTHAND
+ git checkout -b BRANCH origin/BRANCH
+
+After this, you are able to pull BRANCH from git.sv.gnu.org with
+
+ git pull SHORTHAND
+
+You can check out another branch OTHER_BRANCH, i.e. check out
+OTHER_BRANCH to the working tree, with
+
+ git checkout OTHER_BRANCH
+
+E.g. lilypond/translation, which you still have in your local Git
+repository but is no longer checked out since you have created the new
+branch BRANCH.
+
+Note that it is possible to check out another branch while having
+uncommitted changes, but it is not recommended unless you know what
+you are doing; it is recommended to run 'git status' to check this
+kind of issue before checking ouy another branch.
+
+When pulling using SHORTHAND, do not forget to check first that the
+right branch is checked out, i.e. the branch named A in the first part
+of the "A:B" refspec in .git/remotes/SHORTHAND: as a matter of fact,
+when you pull using A:B refspec, Git fetch A on the server as B remote
+branch on your local repository, then tries to merge B into the
+currently checked out branch.
+
+To remember which branch is currently checked out, run 'git branch',
+which will list all branches and mark the currently checked out branch
+with a star, or 'git status'.
+
+
+* To merge branch FOO into branch BAR, i.e. to "add" all changes made
+in branch FOO to branch BAR, run
+
+ git checkout BAR
+ git merge FOO
+
+If any conflict happens, please carefully follow the instructions
+given by 'git merge' -- you usually must resolve conflicts with a text
+editor by merging pieces of files marked with "<<<" "===" and ">>>",
+removing these 3 kinds of conflict marks, then commit the result
+exactly like a usual commit.
+
+For example, as a translator, you will often want to merge master into
+lilypond/translation; on the other hand, the Translations meister
+wants to merge lilypond/translation into master whenever he has
+checked that lilypond/translation builds successfully.
+
+
+* If you play with several Git branches (e.g. master,
+lilypond/translation, 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 BRANCH, run
+
+ git checkout BRANCH
+ git clone -l -s -n . SUBDIR
+ cd SUBDIR
+ git reset --hard
+
+Note that SUBDIR must be a directory name which does not already
+exist. In 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 SUBDIR
+and run 'git pull'; to send changes made on the subrepository back to
+the main repository, run 'git push' from SUBDIR. Note that only one
+branch (the currently checked out branch) is created in the
+subrepository by deafult; it is possible to have several branches in a
+subrepository and do usual operations (checkout, merge, create,
+delete...) on these branches, but this is more difficult to manage
+them and sync them with the main repository, so this possibility is
+not detailed here.
