+Internet is full of heated discussions on the topic: "merge or
+rebase?" Most of them are meaningless. When a DVCS is being used in a
+big team with a big and complex project with many branches there is
+simply no way to avoid merges. So the question's diminished to
+"whether to use rebase, and if yes - when to use rebase?" Considering
+that it is very much recommended not to rebase published commits the
+question's diminished even further: "whether to use rebase on
+non-pushed commits?"
+
+That small question is for the team to decide. The author of the PEP
+recommends to use rebase when pulling, i.e. always do ``git pull
+--rebase`` or even configure automatic setup of rebase for every new
+branch::
+
+ $ git config branch.autosetuprebase always
+
+and configure rebase for existing branches::
+
+ $ git config branch.$NAME.rebase true
+
+For example::
+
+ $ git config branch.v1.rebase true
+ $ git config branch.v2.rebase true
+
+After that ``git pull origin v2`` becomes equivalent to ``git pull
+--rebase origin v2``.
+
+In case when merge is preferred it is recommended to create new
+commits in a separate feature or topic branch while using rebase to
+update the mainline branch. When the topic branch is ready merge it
+into mainline. To avoid a tedious task of resolving large number of
+conflicts at once you can merge the topic branch to the mainline from
+time to time and switch back to the topic branch to continue working
+on it. The entire workflow would be something like::
+
+ $ git checkout -b issue-42 # create a new issue branch and switch to it
+ ...edit/test/commit...
+ $ git checkout v2
+ $ git pull --rebase origin v2 # update v2 from the upstream
+ $ git merge issue-42
+ $ git branch -d issue-42 # delete the topic branch
+ $ git push origin v2
+
+When the topic branch is deleted only the label is removed, commits
+are stayed in the database, they are now merged into v2::
+
+ o--o--o--o--o--M--< v2 - the mainline branch
+ \ /
+ --*--*--* - the topic branch, now unnamed
+
+The topic branch is deleted to avoid cluttering branch namespace with
+small topic branches. Information on what issue was fixed or what
+feature was implemented should be in the commit messages.
