DESCRIPTION
-----------
Each commit between the fork-point and <head> is examined, and compared against
the change each commit between the fork-point and <upstream> introduces.
Commits already included in upstream are prefixed with '-' (meaning "drop from
my local pull"), while commits missing from upstream are prefixed with '+'
(meaning "add to the updated upstream").
The changeset (or "diff") of each commit between the fork-point and <head>
is compared against each commit between the fork-point and <upstream>.
Every commit with a changeset that doesn't exist in the other branch
has its id (sha1) reported, prefixed by a symbol. Those existing only
in the <upstream> branch are prefixed with a minus (-) sign, and those
that only exist in the <head> branch are prefixed with a plus (+) symbol.
Because git-cherry compares the changeset rather than the commit id
(sha1), you can use git-cherry to find out if a commit you made locally
has been applied <upstream> under a different commit id. For example,
this will happen if you're feeding patches <upstream> via email rather
than pushing or pulling commits directly.

Read a packed archive (.pack) from the standard input, expanding
the objects contained within and writing them into the repository in

object::
The unit of storage in git. It is uniquely identified by
the SHA1 of its contents. Consequently, an object can not
be changed.
alternate object database::
Via the alternates mechanism, a repository can inherit part of its
object database from another object database, which is called
"alternate".
object name::
The unique identifier of an object. The hash of the object's contents
using the Secure Hash Algorithm 1 and usually represented by the 40
character hexadecimal encoding of the hash of the object (possibly
followed by a white space).
SHA1::
Synonym for object name.
object identifier::
Synonym for object name.
hash::
In git's context, synonym to object name.
object database::
Stores a set of "objects", and an individual object is identified
by its object name. The objects usually live in `$GIT_DIR/objects/`.
bare repository::
A bare repository is normally an appropriately named
directory with a `.git` suffix that does not have a
locally checked-out copy of any of the files under revision
control. That is, all of the `git` administrative and
control files that would normally be present in the
hidden `.git` sub-directory are directly present in
the `repository.git` directory instead, and no other files
are present and checked out. Usually publishers of public
repositories make bare repositories available.
blob object::
Untyped object, e.g. the contents of a file.
tree object::
An object containing a list of file names and modes along with refs
to the associated blob and/or tree objects. A tree is equivalent
to a directory.
branch::
A non-cyclical graph of revisions, i.e. the complete history of
a particular revision, which is called the branch head. The
branch heads are stored in `$GIT_DIR/refs/heads/`.
tree::
Either a working tree, or a tree object together with the
dependent blob and tree objects (i.e. a stored representation
of a working tree).
cache::
Obsolete for: index.
chain::
A list of objects, where each object in the list contains a
reference to its successor (for example, the successor of a commit
could be one of its parents).
changeset::
BitKeeper/cvsps speak for "commit". Since git does not store
changes, but states, it really does not make sense to use
the term "changesets" with git.
checkout::
The action of updating the working tree to a revision which was
stored in the object database.
cherry-picking::
In SCM jargon, "cherry pick" means to choose a subset of
changes out of a series of changes (typically commits)
and record them as a new series of changes on top of
different codebase. In GIT, this is performed by
"git cherry-pick" command to extract the change
introduced by an existing commit and to record it based
on the tip of the current branch as a new commit.
clean::
A working tree is clean, if it corresponds to the revision
referenced by the current head. Also see "dirty".
commit::
As a verb: The action of storing the current state of the index in the
object database. The result is a revision.
As a noun: Short hand for commit object.
commit object::
An object which contains the information about a particular
revision, such as parents, committer, author, date and the
tree object which corresponds to the top directory of the
stored revision.

directory::
The list you get with "ls" :-)
ent::
Favorite synonym to "tree-ish" by some total geeks. See
`http://en.wikipedia.org/wiki/Ent_(Middle-earth)` for an in-depth
explanation.
fast forward::
A fast-forward is a special type of merge where you have
a revision and you are "merging" another branch's changes
that happen to be a descendant of what you have.
In such these cases, you do not make a new merge commit but
instead just update to his revision. This will happen
frequently on a tracking branch of a remote repository.
fetch::
Fetching a branch means to get the branch's head ref from a
remote repository, to find out which objects are missing from
the local object database, and to get them, too.
file system::
Linus Torvalds originally designed git to be a user space file
system, i.e. the infrastructure to hold files and directories.
That ensured the efficiency and speed of git.
git archive::
Synonym for repository (for arch people).
hash::
In git's context, synonym to object name.
head::
The top of a branch. It contains a ref to the corresponding
commit object.
head ref::
A ref pointing to a head. Often, this is abbreviated to "head".
Head refs are stored in `$GIT_DIR/refs/heads/`.
hook::
During the normal execution of several git commands,
call-outs are made to optional scripts that allow
a developer to add functionality or checking.
Typically, the hooks allow for a command to be pre-verified
and potentially aborted, and allow for a post-notification
after the operation is done.
The hook scripts are found in the `$GIT_DIR/hooks/` directory,
and are enabled by simply making them executable.
index::

stored as objects. The index is a stored version of your working

yet finished (i.e. if the index contains multiple versions of
that file).
unmerged index:
An index which contains unmerged index entries.
master::
The default development branch. Whenever you create a git
repository, a branch named "master" is created, and becomes
the active branch. In most cases, this contains the local
development, though that is purely conventional and not required.
cache::
Obsolete for: index.
merge::
To merge branches means to try to accumulate the changes since a
common ancestor and apply them to the first branch. An automatic
merge uses heuristics to accomplish that. Evidently, an automatic
merge can fail.
working tree::
The set of files and directories currently being worked on,
i.e. you can work in your working tree without using git at all.
object::
The unit of storage in git. It is uniquely identified by
the SHA1 of its contents. Consequently, an object can not
be changed.
directory::
The list you get with "ls" :-)
object database::
Stores a set of "objects", and an individual object is identified
by its object name. The objects usually live in `$GIT_DIR/objects/`.
revision::
A particular state of files and directories which was stored in
the object database. It is referenced by a commit object.

As a noun: Short hand for commit object.
object type:
One of the identifiers "commit","tree","tag" and "blob" describing
the type of an object.
commit object::
An object which contains the information about a particular
revision, such as parents, committer, author, date and the
tree object which corresponds to the top directory of the
stored revision.
octopus::
To merge more than two branches. Also denotes an intelligent
predator.
origin::
The default upstream tracking branch. Most projects have at
least one upstream project which they track. By default
'origin' is used for that purpose. New upstream updates
will be fetched into this branch; you should never commit
to it yourself.
pack::
A set of objects which have been compressed into one file (to save
space or to transmit them efficiently).
pack index::
The list of identifiers, and other information, of the objects in a
pack, to assist in efficiently accessing the contents of a pack.
parent::
A commit object contains a (possibly empty) list of the logical
predecessor(s) in the line of development, i.e. its parents.
changeset::
BitKeeper/cvsps speak for "commit". Since git does not store
changes, but states, it really does not make sense to use
the term "changesets" with git.
pickaxe::
The term pickaxe refers to an option to the diffcore routines
that help select changes that add or delete a given text string.
With the --pickaxe-all option, it can be used to view the
full changeset that introduced or removed, say, a particular
line of text. See gitlink:git-diff[1].
clean::
A working tree is clean, if it corresponds to the revision
referenced by the current head.
plumbing::
Cute name for core git.
dirty::
A working tree is said to be dirty if it contains modifications
which have not been committed to the current branch.
porcelain::
Cute name for programs and program suites depending on core git,
presenting a high level access to core git. Porcelains expose
more of a SCM interface than the plumbing.
head::
The top of a branch. It contains a ref to the corresponding
commit object.
pull::
Pulling a branch means to fetch it and merge it.
branch::
A non-cyclical graph of revisions, i.e. the complete history of
a particular revision, which is called the branch head. The
branch heads are stored in `$GIT_DIR/refs/heads/`.
push::
Pushing a branch means to get the branch's head ref from a remote
repository, find out if it is an ancestor to the branch's local
head ref is a direct, and in that case, putting all objects, which
are reachable from the local head ref, and which are missing from
the remote repository, into the remote object database, and updating
the remote head ref. If the remote head is not an ancestor to the
local head, the push fails.
master::
The default branch. Whenever you create a git repository, a branch
named "master" is created, and becomes the active branch. In most
cases, this contains the local development.
reachable::
An object is reachable from a ref/commit/tree/tag, if there is a
chain leading from the latter to the former.
origin::
The default upstream branch. Most projects have one upstream
project which they track, and by default 'origin' is used for
that purpose. New updates from upstream will be fetched into
this branch; you should never commit to it yourself.
rebase::
To clean a branch by starting from the head of the main line of
development ("master"), and reapply the (possibly cherry-picked)
changes from that branch.
ref::
A 40-byte hex representation of a SHA1 pointing to a particular
object. These may be stored in `$GIT_DIR/refs/`.
A 40-byte hex representation of a SHA1 or a name that denotes
a particular object. These may be stored in `$GIT_DIR/refs/`.
head ref::
A ref pointing to a head. Often, this is abbreviated to "head".
Head refs are stored in `$GIT_DIR/refs/heads/`.
refspec::
A refspec is used by fetch and push to describe the mapping
between remote ref and local ref. They are combined with
a colon in the format <src>:<dst>, preceded by an optional
plus sign, +. For example:
`git fetch $URL refs/heads/master:refs/heads/origin`
means "grab the master branch head from the $URL and store
it as my origin branch head".
And `git push $URL refs/heads/master:refs/heads/to-upstream`
means "publish my master branch head as to-upstream master head
at $URL". See also gitlink:git-push[1]
repository::

topic branch::
A regular git branch that is used by a developer to
identify a conceptual line of development. Since branches
are very easy and inexpensive, it is often desirable to
have several small branches that each contain very well
defined concepts or small incremental yet related changes.
tracking branch::
A regular git branch that is used to follow changes from
another repository. A tracking branch should not contain
direct modifications or have local commits made to it.
A tracking branch can usually be identified as the
right-hand-side ref in a Pull: refspec.
tree object::
An object containing a list of file names and modes along with refs
