+ [--interactive] [--whitespace=<option>] <mbox>...
'git-am' [--skip | --resolved]
DESCRIPTION
Skip the current patch. This is only meaningful when
restarting an aborted patch.
+--whitespace=<option>::
+ This flag is passed to the `git-apply` program that applies
+ the patch.
+
--interactive::
Run interactively, just like git-applymbox.

DESCRIPTION
result. This allows binary files to be patched in a
very limited way.
+--whitespace=<option>::
+ When applying a patch, detect a new or modified line
+ that ends with trailing whitespaces (this includes a
+ line that solely consists of whitespaces). By default,
+ the command outputs warning messages and applies the
+ patch.
+ When `git-apply` is used for statistics and not applying a
+ patch, it defaults to `nowarn`.
+ You can use different `<option>` to control this
+ behaviour:
++
+* `nowarn` turns off the trailing whitespace warning.
+* `warn` outputs warnings for a few such errors, but applies the
+ patch (default).
+* `error` outputs warnings for a few such errors, and refuses
+ to apply the patch.
+* `error-all` is similar to `error` but shows all errors.
+* `strip` outputs warnings for a few such errors, strips out the
+ trailing whitespaces and applies the patch.
+
+
+Configuration
+-------------
+
+apply.whitespace::
+ When no `--whitespace` flag is given from the command
+ line, this configuration item is used as the default.

SYNOPSIS
--------
-'git-read-tree' (<tree-ish> | [[-m | --reset] [-u | -i]] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
+'git-read-tree' (<tree-ish> | [[-m [--aggressive]| --reset] [-u | -i]] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
DESCRIPTION
trees that are not directly related to the current
working tree status into a temporary index file.
+--aggressive::
+ Usually a three-way merge by `git-read-tree` resolves
+ the merge for really trivial cases and leaves other
+ cases unresolved in the index, so that Porcelains can
+ implement different merge policies. This flag makes the
+ command to resolve a few more cases internally:
++
+* when one side removes a path and the other side leaves the path
+ unmodified. The resolution is to remove that path.
+* when both sides remove a path. The resolution is to remove that path.
+* when both sides adds a path identically. The resolution
+ is to add that path.
+
<tree-ish#>::
The id of the tree object(s) to be read/merged.

which I need to download if I have the commit object 'bar', but

+--objects-edge::
+ Similar to `--objects`, but also print the IDs of
+ excluded commits refixed with a `-` character. This is
+ used by `git-pack-objects` to build 'thin' pack, which
+ records objects in deltified form based on objects
+ contained in these excluded commits to reduce network
+ traffic.
+
--unpacked::
Only useful with `--objects`; print the object IDs that
are not in packs.

+A short git tools survey
+========================
+
+
+Introduction
+------------
+
+Apart from git contrib/ area there are some others third-party tools
+you may want to look.
+
+This document presents a brief summary of each tool and the corresponding
+link.
+
+
+Alternative/Augmentative Procelains
+-----------------------------------
+
+ - *Cogito* (http://www.kernel.org/pub/software/scm/cogito/)
+
+ Cogito is a version control system layered on top of the git tree history
+ storage system. It aims at seamless user interface and ease of use,
+ providing generally smoother user experience than the "raw" Core GIT
+ itself and indeed many other version control systems.
+
+
+ - *pg* (http://www.spearce.org/category/projects/scm/pg/)
+
+ pg is a shell script wrapper around GIT to help the user manage a set of
+ patches to files. pg is somewhat like quilt or StGIT, but it does have a
+ slightly different feature set.
+
+
+ - *StGit* (http://www.procode.org/stgit/)
+
+ Stacked GIT provides a quilt-like patch management functionality in the
+ GIT environment. You can easily manage your patches in the scope of GIT
+ until they get merged upstream.
+
+
+History Viewers
+---------------
+
+ - *gitk* (shipped with git-core)
+
+ gitk is a simple TK GUI for browsing history of GIT repositories easily.
+
+
+ - *gitview* (contrib/)
+
+ gitview is a GTK based repository browser for git
+
+
+ - *gitweb* (ftp://ftp.kernel.org/pub/software/scm/gitweb/)
+
+ GITweb provides full-fledged web interface for GIT repositories.
+
+
+ - *qgit* (http://digilander.libero.it/mcostalba/)
+
+ QGit is a git/StGIT GUI viewer built on Qt/C++. QGit could be used
+ to browse history and directory tree, view annotated files, commit
+ changes cherry picking single files or applying patches.
+ Currently it is the fastest and most feature rich among the git
+ viewers and commit tools.
+
+
+
+Foreign SCM interface
+---------------------
+
+ - *git-svn* (contrib/)
+
+ git-svn is a simple conduit for changesets between a single Subversion
+ branch and git.
+
+
+ - *quilt2git / git2quilt* (http://home-tj.org/wiki/index.php/Misc)
+
+ These utilities convert patch series in a quilt repository and commit
+ series in git back and forth.
+
+
+Others
+------
+
+ - *(h)gct* (http://www.cyd.liu.se/users/~freku045/gct/)
+
+ Commit Tool or (h)gct is a GUI enabled commit tool for git and
+ Mercurial (hg). It allows the user to view diffs, select which files
+ to committed (or ignored / reverted) write commit messages and
+ perform the commit itself.
+
+ - *git.el* (contrib/)
+
+ This is an Emacs interface for git. The user interface is modeled on
+ pcl-cvs. It has been developed on Emacs 21 and will probably need some
+ tweaking to work on XEmacs.
-------------------------------------
shows the difference between that previous state and the state two
-commits ago. Also, HEAD~5 can be used as a shorthand for HEAD^^^^^,
+commits ago. Also, HEAD~5 can be used as a shorthand for HEAD{caret}{caret}{caret}{caret}{caret},
and more generally HEAD~n can refer to the nth previous commit.
Commits representing merges have more than one parent, and you can
specify which parent to follow in that case; see
# (included in release tarballs), then default
if VN=$(git-describe --abbrev=4 HEAD 2>/dev/null); then
VN=$(echo "$VN" | sed -e 's/-/./g');
-else
+elif test -f version
+then
VN=$(cat version) || VN="$DEF_VER"
+else
+ VN="$DEF_VER"
fi
VN=$(expr "$VN" : v*'\(.*\)')

-git-svn completely ignores the very limited view of branching that
+git-svn mostly ignores the very limited view of branching that
Subversion has. This allows git-svn to be much easier to use,

+ADVANCED OPTIONS
+----------------
+-b<refname>::
+--branch <refname>::
+ Used with 'fetch' or 'commit'.
+
+ This can be used to join arbitrary git branches to remotes/git-svn
+ on new commits where the tree object is equivalent.
+
+ When used with different GIT_SVN_ID values, tags and branches in
+ SVN can be tracked this way, as can some merges where the heads
+ end up having completely equivalent content. This can even be
+ used to track branches across multiple SVN _repositories_.
+
+ This option may be specified multiple times, once for each
+ branch.
+
+-i<GIT_SVN_ID>::
+--id <GIT_SVN_ID>::
+ This sets GIT_SVN_ID (instead of using the environment). See
+ the section on "Tracking Multiple Repositories or Branches" for
+ more information on using GIT_SVN_ID.
+
COMPATIBILITY OPTIONS
---------------------
+--upgrade::
+ Only used with the 'rebuild' command.
+
+ Run this if you used an old version of git-svn that used
+ 'git-svn-HEAD' instead of 'remotes/git-svn' as the branch
+ for tracking the remote.
+
--no-ignore-externals::
Only used with the 'fetch' and 'rebuild' command.
git-svn commit remotes/git-svn..my-branch
# Something is committed to SVN, pull the latest into your branch::
git-svn fetch && git pull . remotes/git-svn
