+'git-read-tree' (<tree-ish> | [-m [-u|-i]] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
DESCRIPTION
After a successful merge, update the files in the work
tree with the result of the merge.
+-i::
+ Usually a merge requires the index file as well as the
+ files in the working tree are up to date with the
+ current head commit, in order not to lose local
+ changes. This flag disables the check with the working
+ tree and is meant to be used when creating a merge of
+ trees that are not directly related to the current
+ working tree status into a temporary index file.
+
+
<tree-ish#>::
The id of the tree object(s) to be read/merged.

-git-rev-tree(1)
-===============
-v0.1, May 2005
-
-NAME
-----
-git-rev-tree - Provides the revision tree for one or more commits
-
-
-SYNOPSIS
---------
-'git-rev-tree' [--edges] [--cache <cache-file>] [^]<commit> [[^]<commit>]
-
-DESCRIPTION
------------
-Provides the revision tree for one or more commits.
-
-OPTIONS
--------
---edges::
- Show edges (ie places where the marking changes between parent
- and child)
-
---cache <cache-file>::
- Use the specified file as a cache from a previous git-rev-list run
- to speed things up. Note that this "cache" is totally different
- concept from the directory index. Also this option is not
- implemented yet.
-
-[^]<commit>::
- The commit id to trace (a leading caret means to ignore this
- commit-id and below)
-
-Output
-------
-
- <date> <commit>:<flags> [<parent-commit>:<flags> ]\*
-
-<date>::
- Date in 'seconds since epoch'
-
-<commit>::
- id of commit object
-
-<parent-commit>::
- id of each parent commit object (>1 indicates a merge)
-
-<flags>::
-
- The flags are read as a bitmask representing each commit
- provided on the commandline. eg: given the command:
-
- $ git-rev-tree <com1> <com2> <com3>
-
- The output:
-
- <date> <commit>:5
-
- means that <commit> is reachable from <com1>(1) and <com3>(4)
-
-A revtree can get quite large. "git-rev-tree" will eventually allow
-you to cache previous state so that you don't have to follow the whole
-thing down.
-
-So the change difference between two commits is literally
-
- git-rev-tree [commit-id1] > commit1-revtree
- git-rev-tree [commit-id2] > commit2-revtree
- join -t : commit1-revtree commit2-revtree > common-revisions
-
-(this is also how to find the most common parent - you'd look at just
-the head revisions - the ones that aren't referred to by other
-revisions - in "common-revision", and figure out the best one. I
-think.)

-Checking it out
----------------
+Inspecting Changes
+------------------
While creating changes is useful, it's even more useful if you can tell
later what changed. The most useful command for this is another of the
means they are now part of the `master` branch. Only the "Some
work" commit has the plus `+` character in the second column,
because `mybranch` has not been merged to incorporate these
-commits from the master branch.
+commits from the master branch. The string inside brackets
+before the commit log message is a short name you can use to
+name the commit. In the above example, 'master' and 'mybranch'
+are branch heads. 'master~1' is the first parent of 'master'
+branch head. Please see 'git-rev-parse' documentation if you
+see more complex cases.
Now, let's pretend you are the one who did all the work in
`mybranch`, and the fruit of your hard work has finally been merged
back before you push your work when it happens.
+Bundling your work together
+---------------------------
+
+It is likely that you will be working on more than one thing at
+a time. It is easy to use those more-or-less independent tasks
+using branches with git.
+
+We have already seen how branches work in a previous example,
+with "fun and work" example using two branches. The idea is the
+same if there are more than two branches. Let's say you started
+out from "master" head, and have some new code in the "master"
+branch, and two independent fixes in the "commit-fix" and
+"diff-fix" branches:
+
+------------
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+ * [master] Release candidate #1
+---
+ + [diff-fix] Fix rename detection.
+ + [diff-fix~1] Better common substring algorithm.
++ [commit-fix] Fix commit message normalization.
+ + [master] Release candidate #1
++++ [diff-fix~2] Pretty-print messages.
+------------
+
+Both fixes are tested well, and at this point, you want to merge
+in both of them. You could merge in 'diff-fix' first and then
+'commit-fix' next, like this:
+
+------------
+$ git resolve master diff-fix 'Merge fix in diff-fix'
+$ git resolve master commit-fix 'Merge fix in commit-fix'
+------------
+
+Which would result in:
+
+------------
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+ * [master] Merge fix in commit-fix
+---
+ + [master] Merge fix in commit-fix
++ + [commit-fix] Fix commit message normalization.
+ + [master~1] Merge fix in diff-fix
+ ++ [diff-fix] Fix rename detection.
+ ++ [diff-fix~1] Better common substring algorithm.
+ + [master~2] Release candidate #1
++++ [master~3] Pretty-print messages.
+------------
+
+However, there is no particular reason to merge in one branch
+first and the other next, when what you have are a set of truly
+independent changes (if the order mattered, then they are not
+independent by definition). You could instead merge those two
+branches into the current branch at once. First let's undo what
+we just did and start over. We would want to get the master
+branch before these two merges by resetting it to 'master~2':
+
+------------
+$ git reset --hard master~2
+------------
+
+You can make sure 'git show-branch' matches the state before
+those two 'git resolve' you just did. Then, instead of running
+two 'git resolve' commands in a row, you would pull these two
+branch heads (this is known as 'making an Octopus'):
+
+------------
+$ git pull . commit-fix diff-fix
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+ * [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
+---
+ + [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
++ + [commit-fix] Fix commit message normalization.
+ ++ [diff-fix] Fix rename detection.
+ ++ [diff-fix~1] Better common substring algorithm.
+ + [master~1] Release candidate #1
++++ [master~2] Pretty-print messages.
+------------
+
+Note that you should not do Octopus because you can. An octopus
+is a valid thing to do and often makes it easier to view the
+commit history if you are pulling more than two independent
+changes at the same time. However, if you have merge conflicts
+with any of the branches you are merging in and need to hand
+resolve, that is an indication that the development happened in
+those branches were not independent after all, and you should
+merge two at a time, documenting how you resolved the conflicts,
+and the reason why you preferred changes made in one side over
+the other. Otherwise it would make the project history harder
+to follow, not easier.
