+GIT v1.6.2 Release Notes
+========================
+
+Updates since v1.6.1
+--------------------
+
+(subsystems)
+
+(portability)
+
+(performance)
+
+* pack-objects autodetects the number of CPUs available and uses threaded
+  version.
+
+(usability, bells and whistles)
+
+* "git-add -p" learned 'g'oto action to jump directly to a hunk.
+
+* git-cherry defaults to HEAD when the <upstream> argument is not given.
+
+* git-cvsserver can be told not to add extra "via git-CVS emulator" to the
+  commit log message it serves via gitcvs.commitmsgannotation configuration.
+
+* git-diff learned a new option --inter-hunk-context to coalesce close
+  hunks together and show context between them.
+
+* git-filter-branch learned --prune-empty option that discards commits
+  that do not change the contents.
+
+* git-ls-tree learned --full-tree option that shows the path in full
+  regardless of where in the work tree hierarchy the command was started.
+
+* git-mergetool learned -y(--no-prompt) option to disable prompting.
+
+* "git-reset --merge" is a new mode that works similar to the way
+  "git checkout" switches branches, taking the local changes while
+  switching to another commit.
+
+(internal)
+
+
+Fixes since v1.6.1
+------------------
+
+All of the fixes in v1.6.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+* "git-add sub/file" when sub is a submodule incorrectly added the path to
+  the superproject.
+
+* git-bundle did not exclude annotated tags even when a range given from the
+  command line wanted to.
+
+* git-grep did not work correctly for index entries with assume-unchanged bit.
+
+* branch switching and merges had a silly bug that did not validate
+  the correct directory when making sure an existing subdirectory is
+  clean.

+===============
+
+NAME
+----
+git-difftool - compare changes using common merge tools
+
+SYNOPSIS
+--------
+'git difftool' [--tool=<tool>] [--no-prompt] ['git diff' options]
+
+DESCRIPTION
+-----------
+'git-difftool' is a git command that allows you to compare and edit files
+between revisions using common merge tools.  At its most basic level,
+'git-difftool' does what 'git-mergetool' does but its use is for non-merge
+situations such as when preparing commits or comparing changes against
+the index.
+
+'git difftool' is a frontend to 'git diff' and accepts the same
+arguments and options.
+
+See linkgit:git-diff[1] for the full list of supported options.
+
+OPTIONS
+-------
+-t <tool>::
+--tool=<tool>::
+       Use the merge resolution program specified by <tool>.
+       Valid merge tools are:
+       kdiff3, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff, ecmerge, and opendiff
++
+If a merge resolution program is not specified, 'git-difftool'
+will use the configuration variable `merge.tool`.  If the
+configuration variable `merge.tool` is not set, 'git difftool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `mergetool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`mergetool.kdiff3.path`. Otherwise, 'git-difftool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known merge tool programs,
+'git-difftool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `mergetool.<tool>.cmd`.
++
+When 'git-difftool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `merge.tool` configuration variable)
+the configured command line will be invoked with the following
+variables available: `$LOCAL` is set to the name of the temporary
+file containing the contents of the diff pre-image and `$REMOTE`
+is set to the name of the temporary file containing the contents
+of the diff post-image.  `$BASE` is provided for compatibility
+with custom merge tool commands and has the same value as `$LOCAL`.
+
+--no-prompt::
+       Do not prompt before launching a diff tool.
+
+CONFIG VARIABLES
+----------------
+merge.tool::
+       The default merge tool to use.
++
+See the `--tool=<tool>` option above for more details.
+
+merge.keepBackup::
+       The original, unedited file content can be saved to a file with
+       a `.orig` extension.  Defaults to `true` (i.e. keep the backup files).
+
+mergetool.<tool>.path::
+       Override the path for the given tool.  This is useful in case
+       your tool is not in the PATH.
+
+mergetool.<tool>.cmd::
+       Specify the command to invoke the specified merge tool.
++
+See the `--tool=<tool>` option above for more details.
+
+
+SEE ALSO
+--------
+linkgit:git-diff[1]::
+        Show changes between commits, commit and working tree, etc
+
