+rewrite (i.e. otherwise the resulting patch will be a series of
+deletion and insertion mixed together with context lines).
++
+When used with -M, a totally-rewritten file is also considered as the
+source of a rename (usually -M only considers a file that disappeared
+as the source of a rename), and the number `n` controls this aspect of
+the -B option (defaults to 50%). `-B20%` specifies that a change with

 SYNOPSIS
 --------
-'git pull' <options> <repository> <refspec>...
+'git pull' [options] [<repository> [<refspec>...]]
 
 
 DESCRIPTION
 -----------
-Runs 'git fetch' with the given parameters, and calls 'git merge'
-to merge the retrieved head(s) into the current branch.
-With `--rebase`, calls 'git rebase' instead of 'git merge'.
 
-Note that you can use `.` (current directory) as the
-<repository> to pull from the local repository -- this is useful
-when merging local branches into the current branch.
+Incorporates changes from a remote repository into the current
+branch.  In its default mode, `git pull` is shorthand for
+`git fetch` followed by `git merge FETCH_HEAD`.
 
-Also note that options meant for 'git pull' itself and underlying
-'git merge' must be given before the options meant for 'git fetch'.
+More precisely, 'git pull' runs 'git fetch' with the given
+parameters and calls 'git merge' to merge the retrieved branch
+heads into the current branch.
+With `--rebase`, it runs 'git rebase' instead of 'git merge'.
 
-*Warning*: Running 'git pull' (actually, the underlying 'git merge')
+<repository> should be the name of a remote repository as
+passed to linkgit:git-fetch[1].  <refspec> can name an
+arbitrary remote ref (for example, the name of a tag) or even
+a collection of refs with corresponding remote tracking branches
+(e.g., refs/heads/*:refs/remotes/origin/*), but usually it is
+the name of a branch in the remote repository.
+
+Default values for <repository> and <branch> are read from the
+"remote" and "merge" configuration for the current branch
+as set by linkgit:git-branch[1] `--track`.
+
+Assume the following history exists and the current branch is
+"`master`":
+
+------------
+	  A---B---C master on origin
+	 /
+    D---E---F---G master
+------------
+
+Then "`git pull`" will fetch and replay the changes from the remote
+`master` branch since it diverged from the local `master` (i.e., `E`)
+until its current commit (`C`) on top of `master` and record the
+result in a new commit along with the names of the two parent commits
+and a log message from the user describing the changes.
+
+------------
+	  A---B---C remotes/origin/master
+	 /         \
+    D---E---F---G---H master
+------------
+
+See linkgit:git-merge[1] for details, including how conflicts
+are presented and handled.
+
+In git 1.7.0 or later, to cancel a conflicting merge, use
+`git reset --merge`.  *Warning*: In older versions of git, running 'git pull'
 with uncommitted changes is discouraged: while possible, it leaves you
-in a state that is hard to back out of in the case of a conflict.
+in a state that may be hard to back out of in the case of a conflict.
+
+If any of the remote changes overlap with local uncommitted changes,

-"reset --merge" is meant to be used when resetting out of a conflicted
-merge. Any mergy operation guarantees that the work tree file that is
-involved in the merge does not have local change wrt the index before
-it starts, and that it writes the result out to the work tree. So if
-we see some difference between the index and the target and also
-between the index and the work tree, then it means that we are not
-resetting out from a state that a mergy operation left after failing
-with a conflict. That is why we disallow --merge option in this case.

-the reset is disallowed. That's why it is disallowed if there are both
-changes between the working tree and HEAD, and between HEAD and the

-SPECIFYING REVISIONS
---------------------
-
-A revision parameter typically, but not necessarily, names a
-commit object.  They use what is called an 'extended SHA1'
-syntax.  Here are various ways to spell object names.  The
-ones listed near the end of this list are to name trees and
-blobs contained in a commit.
-
-* The full SHA1 object name (40-byte hexadecimal string), or
-  a substring of such that is unique within the repository.
-  E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
-  name the same commit object if there are no other object in
-  your repository whose object name starts with dae86e.
-
-* An output from 'git describe'; i.e. a closest tag, optionally
-  followed by a dash and a number of commits, followed by a dash, a
-  `g`, and an abbreviated object name.
-
-* A symbolic ref name.  E.g. 'master' typically means the commit
-  object referenced by refs/heads/master.  If you
-  happen to have both heads/master and tags/master, you can
-  explicitly say 'heads/master' to tell git which one you mean.
-  When ambiguous, a `<name>` is disambiguated by taking the
-  first match in the following rules:
-
-  . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
-    useful only for `HEAD`, `FETCH_HEAD`, `ORIG_HEAD` and `MERGE_HEAD`);
-
-  . otherwise, `refs/<name>` if exists;
-
-  . otherwise, `refs/tags/<name>` if exists;
-
-  . otherwise, `refs/heads/<name>` if exists;
-
-  . otherwise, `refs/remotes/<name>` if exists;
-
-  . otherwise, `refs/remotes/<name>/HEAD` if exists.
-+
-HEAD names the commit your changes in the working tree is based on.
-FETCH_HEAD records the branch you fetched from a remote repository
-with your last 'git fetch' invocation.
-ORIG_HEAD is created by commands that moves your HEAD in a drastic
-way, to record the position of the HEAD before their operation, so that
-you can change the tip of the branch back to the state before you ran
-them easily.
-MERGE_HEAD records the commit(s) you are merging into your branch
-when you run 'git merge'.
-+
-Note that any of the `refs/*` cases above may come either from
-the `$GIT_DIR/refs` directory or from the `$GIT_DIR/packed-refs` file.
-
-* A ref followed by the suffix '@' with a date specification
-  enclosed in a brace
-  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
-  second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
-  of the ref at a prior point in time.  This suffix may only be
-  used immediately following a ref name and the ref must have an
-  existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state
-  of your *local* ref at a given time; e.g., what was in your local
-  `master` branch last week. If you want to look at commits made during
-  certain times, see `--since` and `--until`.
-
-* A ref followed by the suffix '@' with an ordinal specification
-  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
-  the n-th prior value of that ref.  For example 'master@\{1\}'
-  is the immediate prior value of 'master' while 'master@\{5\}'
-  is the 5th prior value of 'master'. This suffix may only be used
-  immediately following a ref name and the ref must have an existing
-  log ($GIT_DIR/logs/<ref>).
-
-* You can use the '@' construct with an empty ref part to get at a
-  reflog of the current branch. For example, if you are on the
-  branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
-
-* The special construct '@\{-<n>\}' means the <n>th branch checked out
-  before the current one.
-
-* The suffix '@\{upstream\}' to a ref (short form 'ref@\{u\}') refers to
-  the branch the ref is set to build on top of.  Missing ref defaults
-  to the current branch.
-
-* A suffix '{caret}' to a revision parameter (e.g. 'HEAD{caret}') means the first parent of
-  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
-  'rev{caret}'
-  is equivalent to 'rev{caret}1').  As a special rule,
-  'rev{caret}0' means the commit itself and is used when 'rev' is the
-  object name of a tag object that refers to a commit object.
-
-* A suffix '{tilde}<n>' to a revision parameter means the commit
-  object that is the <n>th generation grand-parent of the named
-  commit object, following only the first parent.  I.e. rev~3 is
-  equivalent to rev{caret}{caret}{caret} which is equivalent to
-  rev{caret}1{caret}1{caret}1.  See below for a illustration of
-  the usage of this form.
-
-* A suffix '{caret}' followed by an object type name enclosed in
-  brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
-  could be a tag, and dereference the tag recursively until an
-  object of that type is found or the object cannot be
-  dereferenced anymore (in which case, barf).  `rev{caret}0`
-  introduced earlier is a short-hand for `rev{caret}\{commit\}`.
-
-* A suffix '{caret}' followed by an empty brace pair
-  (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
-  and dereference the tag recursively until a non-tag object is
-  found.
-
-* A colon, followed by a slash, followed by a text (e.g. `:/fix nasty bug`): this names
-  a commit whose commit message starts with the specified text.
-  This name returns the youngest matching commit which is
-  reachable from any ref.  If the commit message starts with a
-  '!', you have to repeat that;  the special sequence ':/!',
-  followed by something else than '!' is reserved for now.
-
-* A suffix ':' followed by a path (e.g. `HEAD:README`); this names the blob or tree
-  at the given path in the tree-ish object named by the part
-  before the colon.
-  ':path' (with an empty part before the colon, e.g. `:README`)
-  is a special case of the syntax described next: content
-  recorded in the index at the given path.
-
-* A colon, optionally followed by a stage number (0 to 3) and a
-  colon, followed by a path (e.g. `:0:README`); this names a blob object in the
-  index at the given path. Missing stage number (and the colon
-  that follows it, e.g. `:README`) names a stage 0 entry. During a merge, stage
-  1 is the common ancestor, stage 2 is the target branch's version
-  (typically the current branch), and stage 3 is the version from
-  the branch being merged.
-
-Here is an illustration, by Jon Loeliger.  Both commit nodes B
-and C are parents of commit node A.  Parent commits are ordered
-left-to-right.

-SPECIFYING RANGES
------------------
-
-History traversing commands such as 'git log' operate on a set
-of commits, not just a single commit.  To these commands,
-specifying a single revision with the notation described in the
-previous section means the set of commits reachable from that
-commit, following the commit ancestry chain.
-
-To exclude commits reachable from a commit, a prefix `{caret}`
-notation is used.  E.g. `{caret}r1 r2` means commits reachable
-from `r2` but exclude the ones reachable from `r1`.
-
-This set operation appears so often that there is a shorthand
-for it.  When you have two commits `r1` and `r2` (named according
-to the syntax explained in SPECIFYING REVISIONS above), you can ask
-for commits that are reachable from r2 excluding those that are reachable
-from r1 by `{caret}r1 r2` and it can be written as `r1..r2`.
-
-A similar notation `r1\...r2` is called symmetric difference
-of `r1` and `r2` and is defined as
-`r1 r2 --not $(git merge-base --all r1 r2)`.
-It is the set of commits that are reachable from either one of
-`r1` or `r2` but not from both.
-
-Two other shorthands for naming a set that is formed by a commit
-and its parent commits exist.  The `r1{caret}@` notation means all
-parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
-all of its parents.
-
-Here are a handful of examples:
-
-   D                G H D
-   D F              G H I J D F
-   ^G D             H D
-   ^D B             E I J F B
-   B...C            G H D E B C
-   ^D B C           E I J F B C
-   C^@              I J F
-   F^! D            G H D F

+
+
+DESCRIPTION
+-----------
+
+Many Git commands take revision parameters as arguments. Depending on
+the command, they denote a specific commit or, for commands which
+walk the revision graph (such as linkgit:git-log[1]), all commits which can
+be reached from that commit. In the latter case one can also specify a
+range of revisions explicitly.
+
+In addition, some Git commands (such as linkgit:git-show[1]) also take
+revision parameters which denote other objects than commits, e.g. blobs
+("files") or trees ("directories of files").

+  followed by a dash and a number of commits, followed by a dash, a
+  `g`, and an abbreviated object name.
+
+* A symbolic ref name.  E.g. 'master' typically means the commit
+  object referenced by refs/heads/master.  If you
+  happen to have both heads/master and tags/master, you can
+  explicitly say 'heads/master' to tell git which one you mean.
+  When ambiguous, a `<name>` is disambiguated by taking the
+  first match in the following rules:
+
+  . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
+    useful only for `HEAD`, `FETCH_HEAD`, `ORIG_HEAD` and `MERGE_HEAD`);
+
+  . otherwise, `refs/<name>` if exists;
+
+  . otherwise, `refs/tags/<name>` if exists;
+
+  . otherwise, `refs/heads/<name>` if exists;
+
+  . otherwise, `refs/remotes/<name>` if exists;
+
+  . otherwise, `refs/remotes/<name>/HEAD` if exists.
++
+HEAD names the commit your changes in the working tree is based on.
+FETCH_HEAD records the branch you fetched from a remote repository
+with your last 'git fetch' invocation.
+ORIG_HEAD is created by commands that moves your HEAD in a drastic
+way, to record the position of the HEAD before their operation, so that
+you can change the tip of the branch back to the state before you ran
+them easily.
+MERGE_HEAD records the commit(s) you are merging into your branch
+when you run 'git merge'.
++
+Note that any of the `refs/*` cases above may come either from
+the `$GIT_DIR/refs` directory or from the `$GIT_DIR/packed-refs` file.
+
+* A ref followed by the suffix '@' with a date specification
+  enclosed in a brace
+  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
+  second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
+  of the ref at a prior point in time.  This suffix may only be
+  used immediately following a ref name and the ref must have an
+  existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state
+  of your *local* ref at a given time; e.g., what was in your local
+  `master` branch last week. If you want to look at commits made during
+  certain times, see `--since` and `--until`.
+
+* A ref followed by the suffix '@' with an ordinal specification
+  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
+  the n-th prior value of that ref.  For example 'master@\{1\}'
+  is the immediate prior value of 'master' while 'master@\{5\}'
+  is the 5th prior value of 'master'. This suffix may only be used
+  immediately following a ref name and the ref must have an existing
+  log ($GIT_DIR/logs/<ref>).
+
+* You can use the '@' construct with an empty ref part to get at a
+  reflog of the current branch. For example, if you are on the
+  branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
+
+* The special construct '@\{-<n>\}' means the <n>th branch checked out
+  before the current one.
+
+* The suffix '@\{upstream\}' to a ref (short form 'ref@\{u\}') refers to
+  the branch the ref is set to build on top of.  Missing ref defaults
+  to the current branch.
+
+* A suffix '{caret}' to a revision parameter (e.g. 'HEAD{caret}') means the first parent of
+  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
+  'rev{caret}'
+  is equivalent to 'rev{caret}1').  As a special rule,
+  'rev{caret}0' means the commit itself and is used when 'rev' is the
+  object name of a tag object that refers to a commit object.
+
+* A suffix '{tilde}<n>' to a revision parameter means the commit
+  object that is the <n>th generation grand-parent of the named
+  commit object, following only the first parent.  I.e. rev~3 is
+  equivalent to rev{caret}{caret}{caret} which is equivalent to
+  rev{caret}1{caret}1{caret}1.  See below for a illustration of
+  the usage of this form.
+
+* A suffix '{caret}' followed by an object type name enclosed in
+  brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
+  could be a tag, and dereference the tag recursively until an
+  object of that type is found or the object cannot be
+  dereferenced anymore (in which case, barf).  `rev{caret}0`
+  introduced earlier is a short-hand for `rev{caret}\{commit\}`.
+
+* A suffix '{caret}' followed by an empty brace pair
+  (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
+  and dereference the tag recursively until a non-tag object is
+  found.
+
+* A colon, followed by a slash, followed by a text (e.g. `:/fix nasty bug`): this names
+  a commit whose commit message starts with the specified text.
+  This name returns the youngest matching commit which is
+  reachable from any ref.  If the commit message starts with a
+  '!', you have to repeat that;  the special sequence ':/!',
+  followed by something else than '!' is reserved for now.
+
+* A suffix ':' followed by a path (e.g. `HEAD:README`); this names the blob or tree
+  at the given path in the tree-ish object named by the part
+  before the colon.
+  ':path' (with an empty part before the colon, e.g. `:README`)
+  is a special case of the syntax described next: content
+  recorded in the index at the given path.
+
+* A colon, optionally followed by a stage number (0 to 3) and a
+  colon, followed by a path (e.g. `:0:README`); this names a blob object in the
+  index at the given path. Missing stage number (and the colon
+  that follows it, e.g. `:README`) names a stage 0 entry. During a merge, stage
+  1 is the common ancestor, stage 2 is the target branch's version
+  (typically the current branch), and stage 3 is the version from
+  the branch being merged.
+
+Here is an illustration, by Jon Loeliger.  Both commit nodes B
+and C are parents of commit node A.  Parent commits are ordered
+left-to-right.
+

+G   H   I   J

+         A

+
+    A =      = A^0
+    B = A^   = A^1     = A~1
+    C = A^2  = A^2
+    D = A^^  = A^1^1   = A~2

+
+SPECIFYING RANGES
+-----------------
+
+History traversing commands such as 'git log' operate on a set
+of commits, not just a single commit.  To these commands,
+specifying a single revision with the notation described in the
+previous section means the set of commits reachable from that
+commit, following the commit ancestry chain.
+
+To exclude commits reachable from a commit, a prefix `{caret}`
+notation is used.  E.g. `{caret}r1 r2` means commits reachable
+from `r2` but exclude the ones reachable from `r1`.
+
+This set operation appears so often that there is a shorthand
+for it.  When you have two commits `r1` and `r2` (named according
+to the syntax explained in SPECIFYING REVISIONS above), you can ask
+for commits that are reachable from r2 excluding those that are reachable
+from r1 by `{caret}r1 r2` and it can be written as `r1..r2`.
+
+A similar notation `r1\...r2` is called symmetric difference
+of `r1` and `r2` and is defined as
+`r1 r2 --not $(git merge-base --all r1 r2)`.
+It is the set of commits that are reachable from either one of
+`r1` or `r2` but not from both.
+
+Two other shorthands for naming a set that is formed by a commit
+and its parent commits exist.  The `r1{caret}@` notation means all
+parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
+all of its parents.
+
+Here are a handful of examples:
+
+   D                G H D
+   D F              G H I J D F
+   ^G D             H D
+   ^D B             E I J F B
+   B...C            G H D E B C
+   ^D B C           E I J F B C
+   C^@              I J F
+   F^! D            G H D F

+svn-fe(1)
+=========
+
+NAME
+----
+svn-fe - convert an SVN "dumpfile" to a fast-import stream
+
+SYNOPSIS
+--------
+svnadmin dump --incremental REPO | svn-fe [url] | git fast-import
+
+DESCRIPTION
+-----------
+
+Converts a Subversion dumpfile (version: 2) into input suitable for
+git-fast-import(1) and similar importers. REPO is a path to a
+Subversion repository mirrored on the local disk. Remote Subversion
+repositories can be mirrored on local disk using the `svnsync`
+command.
+
+INPUT FORMAT
+------------
+Subversion's repository dump format is documented in full in
+`notes/dump-load-format.txt` from the Subversion source tree.
+Files in this format can be generated using the 'svnadmin dump' or
+'svk admin dump' command.
+
+OUTPUT FORMAT
+-------------
+The fast-import format is documented by the git-fast-import(1)
+manual page.
+
+NOTES
+-----
+Subversion dumps do not record a separate author and committer for
+each revision, nor a separate display name and email address for
+each author.  Like git-svn(1), 'svn-fe' will use the name
+
+---------
+user <user@UUID>
+---------
+
+as committer, where 'user' is the value of the `svn:author` property
+and 'UUID' the repository's identifier.
+
+To support incremental imports, 'svn-fe' will put a `git-svn-id`
+line at the end of each commit log message if passed an url on the
+command line.  This line has the form `git-svn-id: URL@REVNO UUID`.
+
+Empty directories and unknown properties are silently discarded.
+
+The resulting repository will generally require further processing
+to put each project in its own repository and to separate the history
+of each branch.  The 'git filter-branch --subdirectory-filter' command
+may be useful for this purpose.
+
+BUGS
+----
+Litters the current working directory with .bin files for
+persistence. Will be fixed when the svn-fe infrastructure is aware of
+a Git working directory.
+
