+
+Fixes since v1.6.0
+------------------
+
+* "git diff --cc" did not honor content mangling specified by

+
+* "git diff --check" incorrectly detected new trailing blank lines when

+
+* "git for-each-ref" tried to dereference NULL when asked for '%(body)" on

+
+* "git format-patch" peeked before the beginning of a string when

+
+* "git help help" did not work correctly.
+
+* "git mailinfo" (hence "git am") was unhappy when MIME multipart message
+  contained garbage after the finishing boundary.
+
+* "git mailinfo" also was unhappy when the "From: " line only had a bare
+  e-mail address.
+
+* "git merge" did not refresh the index correctly when a merge resulted in
+  a fast-forward.
+
+* "git merge" did not resolve a truly trivial merges that can be done
+  without content level merges.
+
+* "git svn dcommit" to a repository with URL that has embedded usernames
+  did not work correctly.

+GIT v1.6.0.2 Release Notes
+==========================
+
+Fixes since v1.6.0.1
+--------------------
+
+* Installation on platforms that needs .exe suffix to git-* programs were
+  broken in 1.6.0.1.
+
+* Installation on filesystems without symbolic links support did nto
+  work well.
+
+* In-tree documentations and test scripts now use "git foo" form to set a
+  better example, instead of the "git-foo" form (which is an acceptable
+  form if you have "PATH=$(git --exec-path):$PATH" in your script)
+
+* Many commands did not use the correct working tree location when used
+  with GIT_WORK_TREE environment settings.
+
+* Some systems needs to use compatibility fnmach and regex libraries
+  independent from each other; the compat/ area has been reorganized to
+  allow this.
+
+
+* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
+  a new line before the second line.
+
+* "git blame -c" did not exactly work like "git annotate" when range
+  boundaries are involved.
+
+* "git checkout file" when file is still unmerged checked out contents from
+  a random high order stage, which was confusing.
+
+* "git clone $there $here/" with extra trailing slashes after explicit
+  local directory name $here did not work as expected.
+
+* "git diff" on tracked contents with CRLF line endings did not drive "less"
+  intelligently when showing added or removed lines.
+
+* "git diff --dirstat -M" did not add changes in subdirectories up
+  correctly for renamed paths.
+
+* "git diff --cumulative" did not imply "--dirstat".
+
+* "git for-each-ref refs/heads/" did not work as expected.
+
+* "git gui" allowed users to feed patch without any context to be applied.
+
+* "git gui" botched parsing "diff" output when a line that begins with two
+  dashes and a space gets removed or a line that begins with two pluses
+  and a space gets added.
+
+* "git gui" translation updates and i18n fixes.
+
+* "git index-pack" is more careful against disk corruption while completing
+  a thin pack.
+
+* "git log -i --grep=pattern" did not ignore case; neither "git log -E
+  --grep=pattern" triggered extended regexp.
+
+* "git log --pretty="%ad" --date=short" did not use short format when
+  showing the timestamp.
+
+* "git log --author=author" match incorrectly matched with the
+  timestamp part of "author " line in commit objects.
+
+* "git log -F --author=author" did not work at all.
+
+* Build procedure for "git shell" that used stub versions of some
+  functions and globals was not understood by linkers on some platforms.
+
+* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
+  and refused to work until the user refreshed the index.
+
+* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
+  use of temporary files.
+
+* "git verify-pack -v" did not work correctly when given more than one
+  packfile.
+
+Also contains many documentation updates.

+GIT v1.6.0.3 Release Notes
+==========================
+
+Fixes since v1.6.0.2
+--------------------
+
+* "git archive --format=zip" did not honor core.autocrlf while
+  --format=tar did.
+
+* Continuing "git rebase -i" was very confused when the user left modified
+  files in the working tree while resolving conflicts.
+
+* Continuing "git rebase -i" was also very confused when the user left
+  some staged changes in the index after "edit".
+
+* "git rebase -i" now honors the pre-rebase hook, just like the
+  other rebase implementations "git rebase" and "git rebase -m".
+
+* "git rebase -i" incorrectly aborted when there is no commit to replay.
+
+* Behaviour of "git diff --quiet" was inconsistent with "diff --exit-code"
+  with the output redirected to /dev/null.
+
+* "git diff --no-index" on binary files no longer outputs a bogus
+  "diff --git" header line.
+
+* "git diff" hunk header patterns with multiple elements separated by LF
+  were not used correctly.
+
+* Hunk headers in "git diff" default to using extended regular
+  expressions, fixing some of the internal patterns on non-GNU
+  platforms.
+
+* New config "diff.*.xfuncname" exposes extended regular expressions
+  for user specified hunk header patterns.
+
+* "git gc" when ejecting otherwise unreachable objects from packfiles into
+  loose form leaked memory.
+
+* "git index-pack" was recently broken and mishandled objects added by
+  thin-pack completion processing under memory pressure.
+
+* "git index-pack" was recently broken and misbehaved when run from inside
+  .git/objects/pack/ directory.
+
+* "git stash apply sash@{1}" was fixed to error out.  Prior versions
+  would have applied stash@{0} incorrectly.
+
+* "git stash apply" now offers a better suggestion on how to continue
+  if the working tree is currently dirty.
+
+* "git for-each-ref --format=%(subject)" fixed for commits with no
+  no newline in the message body.
+
+* "git remote" fixed to protect printf from user input.
+
+* "git remote show -v" now displays all URLs of a remote.
+
+* "git checkout -b branch" was confused when branch already existed.
+
+* "git checkout -q" once again suppresses the locally modified file list.
+
+* "git clone -q", "git fetch -q" asks remote side to not send
+  progress messages, actually making their output quiet.
+
+* Cross-directory renames are no longer used when creating packs.  This
+  allows more graceful behavior on filesystems like sshfs.
+
+* Stale temporary files under $GIT_DIR/objects/pack are now cleaned up
+  automatically by "git prune".
+
+* "git merge" once again removes directories after the last file has
+  been removed from it during the merge.
+
+* "git merge" did not allocate enough memory for the structure itself when
+  enumerating the parents of the resulting commit.
+
+* "git blame -C -C" no longer segfaults while trying to pass blame if
+   it encounters a submodule reference.
+
+* "git rm" incorrectly claimed that you have local modifications when a
+  path was merely stat-dirty.
+
+* "git svn" fixed to display an error message when 'set-tree' failed,
+   instead of a Perl compile error.
+
+* "git submodule" fixed to handle checking out a different commit
+  than HEAD after initializing the submodule.
+
+* The "git commit" error message when there are still unmerged
+  files present was clarified to match "git write-tree".
+
+* "git init" was confused when core.bare or core.sharedRepository are set
+  in system or user global configuration file by mistake.  When --bare or
+  --shared is given from the command line, these now override such
+  settings made outside the repositories.
+
+* Some segfaults due to uncaught NULL pointers were fixed in multiple
+  tools such as apply, reset, update-index.
+
+* Solaris builds now default to OLD_ICONV=1 to avoid compile warnings;
+  Solaris 8 does not define NEEDS_LIBICONV by default.
+
+* "Git.pm" tests relied on unnecessarily more recent version of Perl.
+
+* "gitweb" triggered undef warning on commits without log messages.
+
+* "gitweb" triggered undef warnings on missing trees.
+
+* "gitweb" now removes PATH_INFO from its URLs so users don't have
+  to manually set the URL in the gitweb configuration.
+
+* Bash completion removed support for legacy "git-fetch", "git-push"
+  and "git-pull" as these are no longer installed.  Dashless form
+  ("git fetch") is still however supported.
+
+Many other documentation updates.

+
+* 'git archive' did not work correctly in bare repositories.
+
+* 'git checkout -t -b newbranch' when you are on detached HEAD was broken.
+
+* when we refuse to detect renames because there are too many new or

+
+* 'git send-email' had a small fd leak while scanning directory.

+==========================

+--------------------
+
+* "git checkout" used to crash when your HEAD was pointing at a deleted
+  branch.
+
+* "git checkout" from an un-checked-out state did not allow switching out
+  of the current branch.
+
+* "git diff" always allowed GIT_EXTERNAL_DIFF and --no-ext-diff was no-op for
+  the command.
+
+* Giving 3 or more tree-ish to "git diff" is supposed to show the combined
+  diff from second and subsequent trees to the first one, but the order was
+  screwed up.
+
+* "git fast-export" did not export all tags.
+
+* "git ls-files --with-tree=<tree>" did not work with options other
+  than -c, most notably with -m.
+
+* "git pack-objects" did not make its best effort to honor --max-pack-size
+  option when a single first object already busted the given limit and
+  placed many objects in a single pack.
+
+* "git-p4" fast import frontend was too eager to trigger its keyword expansion
+  logic, even on a keyword-looking string that does not have closing '$' on the
+  same line.
+
+* "git push $there" when the remote $there is defined in $GIT_DIR/branches/$there
+  behaves more like what cg-push from Cogito used to work.
+
+* when giving up resolving a conflicted merge, "git reset --hard" failed
+  to remove new paths from the working tree.
+
+* "git tag" did not complain when given mutually incompatible set of options.
+
+* The message constructed in the internal editor was discarded when "git
+  tag -s" failed to sign the message, which was often caused by the user
+  not configuring GPG correctly.
+
+* "make check" cannot be run without sparse; people may have meant to say
+  "make test" instead, so suggest that.
+
+* Internal diff machinery had a corner case performance bug that choked on
+  a large file with many repeated contents.
+
+* "git repack" used to grab objects out of packs marked with .keep
+  into a new pack.
+
+* Many unsafe call to sprintf() style varargs functions are corrected.
+
+* Also contains quite a few documentation updates.

+GIT v1.6.0 Release Notes
+========================
+
+User visible changes
+--------------------
+
+With the default Makefile settings, most of the programs are now
+installed outside your $PATH, except for "git", "gitk" and
+some server side programs that need to be accessible for technical
+reasons.  Invoking a git subcommand as "git-xyzzy" from the command
+line has been deprecated since early 2006 (and officially announced in
+1.5.4 release notes); use of them from your scripts after adding
+output from "git --exec-path" to the $PATH is still supported in this
+release, but users are again strongly encouraged to adjust their
+scripts to use "git xyzzy" form, as we will stop installing
+"git-xyzzy" hardlinks for built-in commands in later releases.
+
+An earlier change to page "git status" output was overwhelmingly unpopular
+and has been reverted.
+
+Source changes needed for porting to MinGW environment are now all in the
+main git.git codebase.
+
+By default, packfiles created with this version uses delta-base-offset
+encoding introduced in v1.4.4.  Pack idx files are using version 2 that
+allows larger packs and added robustness thanks to its CRC checking,
+introduced in v1.5.2 and v1.4.4.5.  If you want to keep your repositories
+backwards compatible past these versions, set repack.useDeltaBaseOffset
+to false or pack.indexVersion to 1, respectively.
+
+We used to prevent sample hook scripts shipped in templates/ from
+triggering by default by relying on the fact that we install them as
+unexecutable, but on some filesystems, this approach does not work.
+They are now shipped with ".sample" suffix.  If you want to activate
+any of these samples as-is, rename them to drop the ".sample" suffix,
+instead of running "chmod +x" on them.  For example, you can rename
+hooks/post-update.sample to hooks/post-update to enable the sample
+hook that runs update-server-info, in order to make repositories
+friendly to dumb protocols (i.e. HTTP).
+
+GIT_CONFIG, which was only documented as affecting "git config", but
+actually affected all git commands, now only affects "git config".
+GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
+not different from GIT_CONFIG in a useful way, is removed.
+
+The ".dotest" temporary area "git am" and "git rebase" use is now moved
+inside the $GIT_DIR, to avoid mistakes of adding it to the project by
+accident.
+
+An ancient merge strategy "stupid" has been removed.
+
+
+Updates since v1.5.6
+--------------------
+
+(subsystems)
+
+* git-p4 in contrib learned "allowSubmit" configuration to control on
+  which branch to allow "submit" subcommand.
+
+* git-gui learned to stage changes per-line.
+
+(portability)
+
+* Changes for MinGW port have been merged, thanks to Johannes Sixt and
+  gangs.
+
+* Sample hook scripts shipped in templates/ are now suffixed with
+  *.sample.
+
+* perl's in-place edit (-i) does not work well without backup files on Windows;
+  some tests are rewritten to cope with this.
+
+(documentation)
+
+* Updated howto/update-hook-example
+
+* Got rid of usage of "git-foo" from the tutorial and made typography
+  more consistent.
+
+* Disambiguating "--" between revs and paths is finally documented.
+
+(performance, robustness, sanity etc.)
+
+* index-pack used too much memory when dealing with a deep delta chain.
+  This has been optimized.
+
+* reduced excessive inlining to shrink size of the "git" binary.
+
+* verify-pack checks the object CRC when using version 2 idx files.
+
+* When an object is corrupt in a pack, the object became unusable even
+  when the same object is available in a loose form,  We now try harder to
+  fall back to these redundant objects when able.  In particular, "git
+  repack -a -f" can be used to fix such a corruption as long as necessary
+  objects are available.
+
+* Performance of "git-blame -C -C" operation is vastly improved.
+
+* git-clone does not create refs in loose form anymore (it behaves as
+  if you immediately ran git-pack-refs after cloning).  This will help
+  repositories with insanely large number of refs.
+
+* core.fsyncobjectfiles configuration can be used to ensure that the loose
+  objects created will be fsync'ed (this is only useful on filesystems

+
+* "git commit-tree" plumbing can make Octopus with more than 16 parents.
+  "git commit" has been capable of this for quite some time.
+
+(usability, bells and whistles)
+
+* even more documentation pages are now accessible via "man" and "git help".
+
+* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
+  the discovery process of the toplevel of working tree; this may be useful
+  when you are working in a slow network disk and are outside any working tree,
+  as bash-completion and "git help" may still need to run in these places.
+
+* By default, stash entries never expire.  Set reflogexpire in [gc
+  "refs/stash"] to a reasonable value to get traditional auto-expiration
+  behaviour back
+
+* Longstanding latency issue with bash completion script has been
+  addressed.  This will need to be backmerged to 'maint' later.
+
+* pager.<cmd> configuration variable can be used to enable/disable the
+  default paging behaviour per command.
+
+* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
+  manually.
+
+* git-am records the original tip of the branch in ORIG_HEAD before it
+  starts applying patches.
+
+* git-apply can handle a patch that touches the same path more than once
+  much better than before.
+
+* git-apply can be told not to trust the line counts recorded in the input
+  patch but recount, with the new --recount option.
+
+* git-apply can be told to apply a patch to a path deeper than what the
+  patch records with --directory option.
+
+* git-archive can be told to omit certain paths from its output using
+  export-ignore attributes.
+
+* git-archive uses the zlib default compression level when creating
+  zip archive.
+
+* git-archive's command line options --exec and --remote can take their
+  parameters as separate command line arguments, similar to other commands.
+  IOW, both "--exec=path" and "--exec path" are now supported.
+
+* With -v option, git-branch describes the remote tracking statistics
+  similar to the way git-checkout reports by how many commits your branch
+  is ahead/behind.
+
+* git-branch's --contains option used to always require a commit parameter
+  to limit the branches with; it now defaults to list branches that
+  contains HEAD if this parameter is omitted.
+
+* git-branch's --merged and --no-merged option used to always limit the
+  branches relative to the HEAD, but they can now take an optional commit
+  argument that is used in place of HEAD.
+
+* git-bundle can read the revision arguments from the standard input.
+
+* git-cherry-pick can replay a root commit now.
+
+* git-clone can clone from a remote whose URL would be rewritten by
+  configuration stored in $HOME/.gitconfig now.
+
+* "git-clone --mirror" is a handy way to set up a bare mirror repository.
+
+* git-cvsserver learned to respond to "cvs co -c".
+
+* git-diff --check now checks leftover merge conflict markers.
+
+* "git-diff -p" learned to grab a better hunk header lines in
+  BibTex, Pascal/Delphi, and Ruby files and also pays attention to
+  chapter and part boundary in TeX documents.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+  it has branch 'foo/bar', it refuses to lose the existing remote tracking
+  branch and its reflog.  The error message has been improved to suggest
+  pruning the remote if the user wants to proceed and get the latest set
+  of branches from the remote, including such 'foo/bar'.
+
+* fast-export learned to export and import marks file; this can be used to
+  interface with fast-import incrementally.
+
+* fast-import and fast-export learned to export and import gitlinks.
+
+* "gitk" left background process behind after being asked to dig very deep
+  history and the user killed the UI; the process is killed when the UI goes
+  away now.
+
+* git-rebase records the original tip of branch in ORIG_HEAD before it is
+  rewound.
+
+* "git rerere" can be told to update the index with auto-reused resolution
+  with rerere.autoupdate configuration variable.
+
+* git-rev-parse learned $commit^! and $commit^@ notations used in "log"
+  family.  These notations are available in gitk as well, because the gitk
+  command internally uses rev-parse to interpret its arguments.
+
+* git-rev-list learned --children option to show child commits it
+  encountered during the traversal, instead of showing parent commits.
+
+* git-send-mail can talk not just over SSL but over TLS now.
+
+* git-shortlog honors custom output format specified with "--pretty=format:".
+
+* "git-stash save" learned --keep-index option.  This lets you stash away the
+  local changes and bring the changes staged in the index to your working
+  tree for examination and testing.
+
+* git-stash also learned branch subcommand to create a new branch out of
+  stashed changes.
+
+* git-status gives the remote tracking statistics similar to the way
+  git-checkout reports by how many commits your branch is ahead/behind.
+
+* "git-svn dcommit" is now aware of auto-props setting the subversion user
+  has.
+
+* You can tell "git status -u" to even more aggressively omit checking
+  untracked files with --untracked-files=no.
+
+* Original SHA-1 value for "update-ref -d" is optional now.
+
+* Error codes from gitweb are made more descriptive where possible, rather
+  than "403 forbidden" as we used to issue everywhere.
+
+(internal)
+
+* git-merge has been reimplemented in C.
+
+
+Fixes since v1.5.6
+------------------
+
+All of the fixes in v1.5.6 maintenance series are included in
+this release, unless otherwise noted.
+
+ * git-clone ignored its -u option; the fix needs to be backported to
+   'maint';
+
+ * git-mv used to lose the distinction between changes that are staged
+   and that are only in the working tree, by staging both in the index
+   after moving such a path.
+
+ * "git-rebase -i -p" rewrote the parents to wrong ones when amending
+   (either edit or squash) was involved, and did not work correctly
+   when fast forwarding.

+GIT v1.6.1 Release Notes
+========================
+
+Updates since v1.6.0
+--------------------
+
+When some commands (e.g. "git log", "git diff") spawn pager internally, we
+used to make the pager the parent process of the git command that produces
+output.  This meant that the exit status of the whole thing comes from the
+pager, not the underlying git command.  We swapped the order of the
+processes around and you will see the exit code from the command from now
+on.
+
+(subsystems)
+
+* gitk can call out to git-gui to view "git blame" output; git-gui in turn
+  can run gitk from its blame view.
+
+* Various git-gui updates including updated translations.
+
+* Various gitweb updates from repo.or.cz installation.
+
+* Updates to emacs bindings.
+
+(portability)
+
+* A few test scripts used nonportable "grep" that did not work well on
+  some platforms, e.g. Solaris.
+
+* Sample pre-auto-gc script has OS X support.
+
+* Makefile has support for (ancient) FreeBSD 4.9.
+
+(performance)
+
+* Many operations that are lstat(3) heavy can be told to pre-execute
+  necessary lstat(3) in parallel before their main operations, which
+  potentially gives much improved performance for cold-cache cases or in
+  environments with weak metadata caching (e.g. NFS).
+
+* The underlying diff machinery to produce textual output has been
+  optimized, which would result in faster "git blame" processing.
+
+* Most of the test scripts (but not the ones that try to run servers)
+  can be run in parallel.
+
+* Bash completion of refnames in a repository with massive number of
+  refs has been optimized.
+
+* Cygwin port uses native stat/lstat implementations when applicable,
+  which leads to improved performance.
+
+* "git push" pays attention to alternate repositories to avoid sending
+  unnecessary objects.
+
+* "git svn" can rebuild an out-of-date rev_map file.
+
+(usability, bells and whistles)
+
+* When you mistype a command name, git helpfully suggests what it guesses
+  you might have meant to say.  help.autocorrect configuration can be set
+  to a non-zero value to accept the suggestion when git can uniquely
+  guess.
+
+* The packfile machinery hopefully is more robust when dealing with
+  corrupt packs if redundant objects involved in the corruption are
+  available elsewhere.
+
+* "git add -N path..." adds the named paths as an empty blob, so that
+  subsequent "git diff" will show a diff as if they are creation events.
+
+* "git add" gained a built-in synonym for people who want to say "stage
+  changes" instead of "add contents to the staging area" which amounts
+  to the same thing.
+
+* "git apply" learned --include=paths option, similar to the existing
+  --exclude=paths option.
+
+* "git bisect" is careful about a user mistake and suggests testing of
+  merge base first when good is not a strict ancestor of bad.
+
+* "git bisect skip" can take a range of commits.
+
+* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
+  by default.
+
+* "git check-attr --stdin" can check attributes for multiple paths.
+
+* "git checkout --track origin/hack" used to be a syntax error.  It now
+  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
+  said "git checkout --track -b hack origin/hack".
+
+* "git checkout --ours/--theirs" can be used to check out one side of a
+  conflicting merge during conflict resolution.
+
+* "git checkout -m" can be used to recreate the initial conflicted state
+  during conflict resolution.
+
+* "git cherry-pick" can also utilize rerere for conflict resolution.
+
+* "git clone" learned to be verbose with -v
+
+* "git commit --author=$name" can look up author name from existing
+  commits.
+
+* output from "git commit" has been reworded in a more concise and yet
+  more informative way.
+
+* "git count-objects" reports the on-disk footprint for packfiles and
+  their corresponding idx files.
+
+* "git daemon" learned --max-connections=<count> option.
+
+* "git daemon" exports REMOTE_ADDR to record client address, so that
+  spawned programs can act differently on it.
+
+* "git describe --tags" favours closer lightweight tags than farther
+  annotated tags now.
+
+* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
+  configuration option.
+
+* "git diff" learned to put more sensible hunk headers for Python,
+  HTML and ObjC contents.
+
+* "git diff" learned to vary the a/ vs b/ prefix depending on what are
+  being compared, controlled by diff.mnemonicprefix configuration.
+
+* "git diff" learned --dirstat-by-file to count changed files, not number
+  of lines, when summarizing the global picture.
+
+* "git diff" learned "textconv" filters --- a binary or hard-to-read
+  contents can be munged into human readable form and the difference
+  between the results of the conversion can be viewed (obviously this
+  cannot produce a patch that can be applied, so this is disabled in
+  format-patch among other things).
+
+* "--cached" option to "git diff has an easier to remember synonym "--staged",
+  to ask "what is the difference between the given commit and the
+  contents staged in the index?"
+
+* "git for-each-ref" learned "refname:short" token that gives an
+  unambiguously abbreviated refname.
+
+* Auto-numbering of the subject lines is the default for "git
+  format-patch" now.
+
+* "git grep" learned to accept -z similar to GNU grep.
+
+* "git help" learned to use GIT_MAN_VIEWER environment variable before
+  using "man" program.
+
+* "git imap-send" can optionally talk SSL.
+
+* "git index-pack" is more careful against disk corruption while
+  completing a thin pack.
+
+* "git log --check" and "git log --exit-code" passes their underlying diff
+  status with their exit status code.
+
+* "git log" learned --simplify-merges, a milder variant of --full-history;
+  "gitk --simplify-merges" is easier to view than with --full-history.
+
+* "git log" learned "--source" to show what ref each commit was reached
+  from.
+
+* "git log" also learned "--simplify-by-decoration" to show the
+  birds-eye-view of the topology of the history.
+
+* "git log --pretty=format:" learned "%d" format element that inserts
+  names of tags that point at the commit.
+
+* "git merge --squash" and "git merge --no-ff" into an unborn branch are
+  noticed as user errors.
+
+* "git merge -s $strategy" can use a custom built strategy if you have a
+  command "git-merge-$strategy" on your $PATH.
+
+* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
+  "-q"uietly.
+
+* "git push" can be told to reject deletion of refs with receive.denyDeletes
+  configuration.
+
+* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
+
+* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
+
+* "git reflog expire branch" can be used in place of "git reflog expire
+  refs/heads/branch".
+
+* "git remote show $remote" lists remote branches one-per-line now.
+
+* "git send-email" can be given revision range instead of files and
+  maildirs on the command line, and automatically runs format-patch to
+  generate patches for the given revision range.
+
+* "git submodule foreach" subcommand allows you to iterate over checked
+  out submodules.
+
+* "git submodule sync" subcommands allows you to update the origin URL
+  recorded in submodule directories from the toplevel .gitmodules file.
+
+* "git svn branch" can create new branches on the other end.
+
+* "gitweb" can use more saner PATH_INFO based URL.
+
+(internal)
+
+* "git hash-object" learned to lie about the path being hashed, so that
+  correct gitattributes processing can be done while hashing contents
+  stored in a temporary file.
+
+* various callers of git-merge-recursive avoid forking it as an external
+  process.
+
+* Git class defined in "Git.pm" can be subclasses a bit more easily.
+
+* We used to link GNU regex library as a compatibility layer for some
+  platforms, but it turns out it is not necessary on most of them.
+
+* Some path handling routines used fixed number of buffers used alternately
+  but depending on the call depth, this arrangement led to hard to track
+  bugs.  This issue is being addressed.
+
+
+Fixes since v1.6.0
+------------------
+
+All of the fixes in v1.6.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+* Porcelains implemented as shell scripts were utterly confused when you
+  entered to a subdirectory of a work tree from sideways, following a
+  symbolic link (this may need to be backported to older releases later).
+
+* Tracking symbolic links would work better on filesystems whose lstat()
+  returns incorrect st_size value for them.
+
+* "git add" and "git update-index" incorrectly allowed adding S/F when S
+  is a tracked symlink that points at a directory D that has a path F in
+  it (we still need to fix a similar nonsense when S is a submodule and F
+  is a path in it).
+
+* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
+  --3way options given from the command line initially.
+
+* "git diff --stdin" used to take two trees on a line and compared them,
+  but we dropped support for such a use case long time ago.  This has
+  been resurrected.
+
+* "git filter-branch" failed to rewrite a tag name with slashes in it.
+
+* "git http-push" did not understand URI scheme other than opaquelocktoken
+  when acquiring a lock from the server (this may need to be backported to
+  older releases later).
+
+* After "git rebase -p" stopped with conflicts while replaying a merge,
+ "git rebase --continue" did not work (may need to be backported to older
+  releases).
+
+* "git revert" records relative to which parent a revert was made when
+  reverting a merge.  Together with new documentation that explains issues
+  around reverting a merge and merging from the updated branch later, this
+  hopefully will reduce user confusion (this may need to be backported to
+  older releases later).
+
+* "git rm --cached" used to allow an empty blob that was added earlier to
+  be removed without --force, even when the file in the work tree has
+  since been modified.
+
+* "git push --tags --all $there" failed with generic usage message without
+  telling saying these two options are incompatible.
+
+* "git log --author/--committer" match used to potentially match the
+  timestamp part, exposing internal implementation detail.  Also these did
+  not work with --fixed-strings match at all.
+
+* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
+  correctly.

+This command uploads a mailbox generated with 'git-format-patch'
+into an IMAP drafts folder.  This allows patches to be sent as
+other email is when using mail clients that cannot read mailbox
 files directly.
 
 Typical usage is something like:
 
-git-format-patch --signoff --stdout --attach origin | git-imap-send
+git format-patch --signoff --stdout --attach origin | git imap-send
 
 
 CONFIGURATION
 -------------
 
-git-imap-send requires the following values in the repository
-configuration file (shown with examples):
+To use the tool, imap.folder and either imap.tunnel or imap.host must be set
+to appropriate values.
+
+Variables
+~~~~~~~~~
+
+imap.folder::
+	The folder to drop the mails into, which is typically the Drafts
+	folder. For example: "INBOX.Drafts", "INBOX/Drafts" or
+	"[Gmail]/Drafts". Required to use imap-send.
+
+imap.tunnel::
+	Command used to setup a tunnel to the IMAP server through which
+	commands will be piped instead of using a direct network connection
+	to the server. Required when imap.host is not set to use imap-send.
+
+imap.host::
+	A URL identifying the server. Use a `imap://` prefix for non-secure
+	connections and a `imaps://` prefix for secure connections.
+	Ignored when imap.tunnel is set, but required to use imap-send
+	otherwise.
+
+imap.user::
+	The username to use when logging in to the server.
+
+imap.password::
+	The password to use when logging in to the server.
+
+imap.port::
+	An integer port number to connect to on the server.
+	Defaults to 143 for imap:// hosts and 993 for imaps:// hosts.
+	Ignored when imap.tunnel is set.
+
+imap.sslverify::
+	A boolean to enable/disable verification of the server certificate
+	used by the SSL/TLS connection. Default is `true`. Ignored when
+	imap.tunnel is set.
+
+Examples
+~~~~~~~~
+
+Using tunnel mode:
 
 ..........................
 [imap]
-    Folder = "INBOX.Drafts"
+    folder = "INBOX.Drafts"
+    tunnel = "ssh -q -C user@example.com /usr/bin/imapd ./Maildir 2> /dev/null"
+..........................
 
+Using direct mode:
+
+.........................
 [imap]
-    Tunnel = "ssh -q user@server.com /usr/bin/imapd ./Maildir 2> /dev/null"
+    folder = "INBOX.Drafts"
+    host = imap://imap.example.com
+    user = bob
+    pass = p4ssw0rd
+..........................
+
+Using direct mode with SSL:

+ancestor if the latter is an ancestor of the former.  A common ancestor
+that does not have any better common ancestor is a 'best common
+ancestor', i.e. a 'merge base'.  Note that there can be more than one
+merge base for a pair of commits.
 
-Given a selection of equally good common ancestors it should not be
-relied on to decide in any particular way.
-
-The "git-merge-base" algorithm is still in flux - use the source...
+Among the two commits to compute the merge base from, one is specified by
+the first commit argument on the command line; the other commit is a
+(possibly hypothetical) commit that is a merge across all the remaining
+commits on the command line.  As the most common special case, specifying only
+two commits on the command line means computing the merge base between
+the given two commits.
 
 OPTIONS

+	Output all merge bases for the commits, instead of just one.
+
+DISCUSSION
+----------
+
+Given two commits 'A' and 'B', `git merge-base A B` will output a commit
+which is reachable from both 'A' and 'B' through the parent relationship.
+
+For example, with this topology:
+
+		 o---o---o---B
+		/
+	---o---1---o---o---o---A
+
+the merge base between 'A' and 'B' is '1'.
+
+Given three commits 'A', 'B' and 'C', `git merge-base A B C` will compute the
+merge base between 'A' and a hypothetical commit 'M', which is a merge
+between 'B' and 'C'.  For example, with this topology:
+
+	       o---o---o---o---C
+	      /
+	     /   o---o---o---B
+	    /   /
+	---2---1---o---o---o---A
+
+the result of `git merge-base A B C` is '1'.  This is because the
+equivalent topology with a merge commit 'M' between 'B' and 'C' is:
+
+
+	       o---o---o---o---o
+	      /                 \
+	     /   o---o---o---o---M
+	    /   /
+	---2---1---o---o---o---A
+
+and the result of `git merge-base A M` is '1'.  Commit '2' is also a
+common ancestor between 'A' and 'M', but '1' is a better common ancestor,
+because '2' is an ancestor of '1'.  Hence, '2' is not a merge base.
+
+When the history involves criss-cross merges, there can be more than one
+'best' common ancestor for two commits.  For example, with this topology:
+
+       ---1---o---A
+	   \ /
+	    X
+	   / \
+       ---2---o---o---B
+
+both '1' and '2' are merge-bases of A and B.  Neither one is better than
+the other (both are 'best' merge bases).  When the `--all` option is not given,
+it is unspecified which best one is output.

 HOW MERGE WORKS
@@ -58,49 +57,32 @@ HOW MERGE WORKS
 
 A merge is always between the current `HEAD` and one or more
 commits (usually, branch head or tag), and the index file must
-exactly match the
-tree of `HEAD` commit (i.e. the contents of the last commit) when
-it happens.  In other words, `git-diff --cached HEAD` must
-report no changes.
-
-[NOTE]
-This is a bit of a lie.  In certain special cases, your index is
-allowed to be different from the tree of the `HEAD` commit.  The most
-notable case is when your `HEAD` commit is already ahead of what
-is being merged, in which case your index can have arbitrary
-differences from your `HEAD` commit.  Also, your index entries
-may have differences from your `HEAD` commit that match
-the result of a trivial merge (e.g. you received the same patch
-from an external source to produce the same result as what you are
-merging).  For example, if a path did not exist in the common
-ancestor and your head commit but exists in the tree you are
-merging into your repository, and if you already happen to have
-that path exactly in your index, the merge does not have to
-fail.
-
-Otherwise, merge will refuse to do any harm to your repository
-(that is, it may fetch the objects from remote, and it may even
-update the local branch used to keep track of the remote branch
-with `git pull remote rbranch:lbranch`, but your working tree,
-`.git/HEAD` pointer and index file are left intact).
-
-You may have local modifications in the working tree files.  In
-other words, `git-diff` is allowed to report changes.
-However, the merge uses your working tree as the working area,
-and in order to prevent the merge operation from losing such
-changes, it makes sure that they do not interfere with the
-merge. Those complex tables in read-tree documentation define
-what it means for a path to "interfere with the merge".  And if
-your local modifications interfere with the merge, again, it
-stops before touching anything.
-
-So in the above two "failed merge" case, you do not have to
-worry about loss of data --- you simply were not ready to do

+HOW CONFLICTS ARE PRESENTED
+---------------------------
+
+During a merge, the working tree files are updated to reflect the result
+of the merge.  Among the changes made to the common ancestor's version,
+non-overlapping ones (that is, you changed an area of the file while the
+other side left that area intact, or vice versa) are incorporated in the
+final result verbatim.  When both sides made changes to the same area,
+however, git cannot randomly pick one side over the other, and asks you to
+resolve it by leaving what both sides did to that area.
+
+By default, git uses the same style as that is used by "merge" program
+from the RCS suite to present such a conflicted hunk, like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+The area where a pair of conflicting changes happened is marked with markers
+"`<<<<<<<`", "`=======`", and "`>>>>>>>`".  The part before the "`=======`"
+is typically your side, and the part afterwards is typically their side.
+
+The default format does not show what the original said in the conflicting
+area.  You cannot tell how many lines are deleted and replaced with
+Barbie's remark on your side.  The only thing you can tell is that your
+side wants to say it is hard and you'd prefer to go shopping, while the
+other side wants to claim it is easy.
+
+An alternative style can be used by setting the "merge.conflictstyle"
+configuration variable to "diff3".  In "diff3" style, the above conflict
+may look like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+|||||||

+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+In addition to the "`<<<<<<<`", "`=======`", and "`>>>>>>>`" markers, it uses
+another "`|||||||`" marker that is followed by the original text.  You can
+tell that the original just stated a fact, and your side simply gave in to
+that statement and gave up, while the other side tried to have a more
+positive attitude.  You can sometimes come up with a better resolution by
+viewing the original.

+ * Use a mergetool.  'git mergetool' to launch a graphical
+   mergetool which will work you through the merge.
+
+ * Look at the diffs.  'git diff' will show a three-way diff,
+   highlighting changes from both the HEAD and remote versions.
+
+ * Look at the diffs on their own. 'git log --merge -p <path>'
+   will show diffs first for the HEAD version and then the
+   remote version.
+
+ * Look at the originals.  'git show :1:filename' shows the
+   common ancestor, 'git show :2:filename' shows the HEAD
+   version and 'git show :3:filename' shows the remote version.

+RECOVERING FROM UPSTREAM REBASE
+-------------------------------
+
+Rebasing (or any other form of rewriting) a branch that others have
+based work on is a bad idea: anyone downstream of it is forced to
+manually fix their history.  This section explains how to do the fix
+from the downstream's point of view.  The real fix, however, would be
+to avoid rebasing the upstream in the first place.
+
+To illustrate, suppose you are in a situation where someone develops a
+'subsystem' branch, and you are working on a 'topic' that is dependent
+on this 'subsystem'.  You might end up with a history like the
+following:
+
+------------
+    o---o---o---o---o---o---o---o---o  master
+	 \
+	  o---o---o---o---o  subsystem
+			   \
+			    *---*---*  topic
+------------
+
+If 'subsystem' is rebased against 'master', the following happens:
+
+------------
+    o---o---o---o---o---o---o---o  master
+	 \			 \
+	  o---o---o---o---o	  o'--o'--o'--o'--o'  subsystem
+			   \
+			    *---*---*  topic
+------------
+
+If you now continue development as usual, and eventually merge 'topic'
+to 'subsystem', the commits from 'subsystem' will remain duplicated forever:
+
+------------
+    o---o---o---o---o---o---o---o  master
+	 \			 \
+	  o---o---o---o---o	  o'--o'--o'--o'--o'--M	 subsystem
+			   \			     /
+			    *---*---*-..........-*--*  topic
+------------
+
+Such duplicates are generally frowned upon because they clutter up
+history, making it harder to follow.  To clean things up, you need to
+transplant the commits on 'topic' to the new 'subsystem' tip, i.e.,
+rebase 'topic'.  This becomes a ripple effect: anyone downstream from
+'topic' is forced to rebase too, and so on!
+
+There are two kinds of fixes, discussed in the following subsections:
+
+Easy case: The changes are literally the same.::
+
+	This happens if the 'subsystem' rebase was a simple rebase and
+	had no conflicts.
+
+Hard case: The changes are not the same.::
+
+	This happens if the 'subsystem' rebase had conflicts, or used
+	`\--interactive` to omit, edit, or squash commits; or if the
+	upstream used one of `commit \--amend`, `reset`, or
+	`filter-branch`.
+
+
+The easy case
+~~~~~~~~~~~~~
+
+Only works if the changes (patch IDs based on the diff contents) on
+'subsystem' are literally the same before and after the rebase
+'subsystem' did.
+
+In that case, the fix is easy because 'git-rebase' knows to skip
+changes that are already present in the new upstream.  So if you say
+(assuming you're on 'topic')
+------------
+    $ git rebase subsystem
+------------
+you will end up with the fixed history
+------------
+    o---o---o---o---o---o---o---o  master
+				 \
+				  o'--o'--o'--o'--o'  subsystem
+						   \
+						    *---*---*  topic
+------------
+
+
+The hard case
+~~~~~~~~~~~~~
+
+Things get more complicated if the 'subsystem' changes do not exactly
+correspond to the ones before the rebase.
+
+NOTE: While an "easy case recovery" sometimes appears to be successful
+      even in the hard case, it may have unintended consequences.  For
+      example, a commit that was removed via `git rebase
+      \--interactive` will be **resurrected**!
+
+The idea is to manually tell 'git-rebase' "where the old 'subsystem'
+ended and your 'topic' began", that is, what the old merge-base
+between them was.  You will have to find a way to name the last commit
+of the old 'subsystem', for example:
+
+* With the 'subsystem' reflog: after 'git-fetch', the old tip of
+  'subsystem' is at `subsystem@\{1}`.  Subsequent fetches will
+  increase the number.  (See linkgit:git-reflog[1].)
+
+* Relative to the tip of 'topic': knowing that your 'topic' has three
+  commits, the old tip of 'subsystem' must be `topic~3`.
+
+You can then transplant the old `subsystem..topic` to the new tip by
+saying (for the reflog case, and assuming you are on 'topic' already):
+------------
+    $ git rebase --onto subsystem subsystem@{1}
+------------
+
+The ripple effect of a "hard case" recovery is especially bad:
+'everyone' downstream from 'topic' will now have to perform a "hard
+case" recovery too!

-If the file `.mailmap` exists, it will be used for mapping author

-the author name followed by the email address enclosed by
-'<' and '>'. Use hash '#' for comments. Example:
+If a file `.mailmap` exists at the toplevel of the repository,
+it is used to map an author email address to a canonical real name. This
+can be used to coalesce together commits by the same person where their
+name was spelled differently (whether with the same email address or
+not).
+
+Each line in the file consists, in this order, of the canonical real name
+of an author, whitespace, and an email address (enclosed by '<' and '>')
+to map to the name. Use hash '#' for comments, either on their own line,
+or after the email address.
+
+A canonical name may appear in more than one line, associated with
+different email addresses, but it doesn't make sense for a given address
+to appear more than once (if that happens, a later line overrides the
+earlier ones).
+
+So, for example, if your history contains commits by two authors, Jane
+and Joe, whose names appear in the repository under several forms:
+
+------------
+Joe Developer <joe@example.com>
+Joe R. Developer <joe@example.com>
+Jane Doe <jane@example.com>
+Jane Doe <jane@laptop.(none)>
+Jane D. <jane@desktop.(none)>
+------------
+
+Then, supposing Joe wants his middle name initial used, and Jane prefers
+her family name fully spelled out, a proper `.mailmap` file would look like:
 
 ------------
-# Keep alphabetized
-Adam Morrow <adam@localhost.localdomain>
-Eve Jones <eve@laptop.(none)>
+# Note how we don't need an entry for <jane@laptop.(none)>, because the
+# real name of that author is correct already, and coalesced directly.

+DESCRIPTION
+-----------
+Submodules allow foreign repositories to be embedded within
+a dedicated subdirectory of the source tree, always pointed
+at a particular commit.
+
+They are not to be confused with remotes, which are meant mainly
+for branches of the same project; submodules are meant for
+different projects you would like to make part of your source tree,
+while the history of the two projects still stays completely
+independent and you cannot modify the contents of the submodule
+from within the main project.
+If you want to merge the project histories and want to treat the
+aggregated whole as a single project from then on, you may want to
+add a remote for the other project and use the 'subtree' merge strategy,
+instead of treating the other project as a submodule. Directories
+that come from both projects can be cloned and checked out as a whole
+if you choose to go that route.
+
+Submodules are composed from a so-called `gitlink` tree entry
+in the main repository that refers to a particular commit object
+within the inner repository that is completely separate.
+A record in the `.gitmodules` file at the root of the source
+tree assigns a logical name to the submodule and describes
+the default URL the submodule shall be cloned from.
+The logical name can be used for overriding this URL within your
+local repository configuration (see 'submodule init').
+
+This command will manage the tree entries and contents of the
+gitmodules file for you, as well as inspect the status of your
+submodules and update them.
+When adding a new submodule to the tree, the 'add' subcommand
+is to be used.  However, when pulling a tree containing submodules,
+these will not be checked out by default;
+the 'init' and 'update' subcommands will maintain submodules
+checked out and at appropriate revision in your working tree.
+You can briefly inspect the up-to-date status of your submodules
+using the 'status' subcommand and get a detailed overview of the
+difference between the index and checkouts using the 'summary'
+subcommand.
 
 
 COMMANDS
 --------
 add::
 	Add the given repository as a submodule at the given path
-	to the changeset to be committed next.  If path is a valid
-	repository within the project, it is added as is. Otherwise,
-	repository is cloned at the specified path. path is added to the
-	changeset and registered in .gitmodules.   If no path is

-	If the repository url begins with ./ or ../, it is stored as
-	given but resolved as a relative path from the main project's
-	url when cloning.
+	to the changeset to be committed next to the current
+	project: the current project is termed the "superproject".
++
+This requires two arguments: <repository> and <path>.
++
+<repository> is the URL of the new submodule's origin repository.
+This may be either an absolute URL, or (if it begins with ./
+or ../), the location relative to the superproject's origin
+repository.
++
+<path> is the relative location for the cloned submodule to
+exist in the superproject. If <path> does not exist, then the
+submodule is created by cloning from the named URL. If <path> does
+exist and is already a valid git repository, then this is added
+to the changeset without cloning. This second form is provided
+to ease creating a new submodule from scratch, and presumes
+the user will later push the submodule to the given URL.
++
+In either case, the given URL is recorded into .gitmodules for
+use by subsequent users cloning the superproject. If the URL is
+given relative to the superproject's repository, the presumption
+is the superproject and submodule repositories will be kept
+together in the same relative location, and only the
+superproject's URL needs to be provided: git-submodule will correctly
+locate the submodule using the relative URL in .gitmodules.

+'git-svn' is a simple conduit for changesets between Subversion and git.
+It provides a bidirectional flow of changes between a Subversion and a git
+repository.
 
-git-svn was originally designed for an individual developer who wants a
-bidirectional flow of changesets between a single branch in Subversion
-and an arbitrary number of branches in git.  Since its inception,
-git-svn has gained the ability to track multiple branches in a manner
-similar to git-svnimport.
+'git-svn' can track a single Subversion branch simply by using a
+URL to the branch, follow branches laid out in the Subversion recommended
+method (trunk, branches, tags directories) with the --stdlayout option, or
+follow branches in any layout with the -T/-t/-b options (see options to
+'init' below, and also the 'clone' command).
 
-git-svn is especially useful when it comes to tracking repositories
-not organized in the way Subversion developers recommend (trunk,
-branches, tags directories).
+Once tracking a Subversion branch (with any of the above methods), the git
+repository can be updated from Subversion by the 'fetch' command and
+Subversion updated from git by the 'dcommit' command.

+Performing text diffs of binary files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Sometimes it is desirable to see the diff of a text-converted
+version of some binary files. For example, a word processor
+document can be converted to an ASCII text representation, and
+the diff of the text shown. Even though this conversion loses
+some information, the resulting diff is useful for human
+viewing (but cannot be applied directly).
+
+The `textconv` config option is used to define a program for
+performing such a conversion. The program should take a single
+argument, the name of a file to convert, and produce the
+resulting text on stdout.
+
+For example, to show the diff of the exif information of a
+file instead of the binary information (assuming you have the
+exif tool installed):
+
+------------------------
+[diff "jpg"]
+	textconv = exif
+------------------------
+
+NOTE: The text conversion is generally a one-way conversion;
+in this example, we lose the actual image contents and focus
+just on the text data. This means that diffs generated by
+textconv are _not_ suitable for applying. For this reason,
+only `git diff` and the `git log` family of commands (i.e.,
+log, whatchanged, show) will perform text conversion. `git
+format-patch` will never generate this output. If you want to
+send somebody a text-converted diff of a binary file (e.g.,
+because it quickly conveys the changes you have made), you
+should generate it separately and send it as a comment _in
+addition to_ the usual binary diff that you might send.

+
+USING ATTRIBUTE MACROS
+----------------------
+
+You do not want any end-of-line conversions applied to, nor textual diffs
+produced for, any binary file you track.  You would need to specify e.g.
+
+------------
+*.jpg -crlf -diff
+------------
+
+but that may become cumbersome, when you have many attributes.  Using
+attribute macros, you can specify groups of attributes set or unset at
+the same time.  The system knows a built-in attribute macro, `binary`:
+
+------------
+*.jpg binary
+------------
+
+which is equivalent to the above.  Note that the attribute macros can only
+be "Set" (see the above example that sets "binary" macro as if it were an
+ordinary attribute --- setting it in turn unsets "crlf" and "diff").
+
+
+DEFINING ATTRIBUTE MACROS
+-------------------------
+
+Custom attribute macros can be defined only in the `.gitattributes` file
+at the toplevel (i.e. not in any subdirectory).  The built-in attribute
+macro "binary" is equivalent to:
+
+------------
+[attr]binary -diff -crlf

+This manual describes the convention used throughout git CLI.
+
+Many commands take revisions (most often "commits", but sometimes
+"tree-ish", depending on the context and command) and paths as their
+arguments.  Here are the rules:
+
+ * Revisions come first and then paths.
+   E.g. in `git diff v1.0 v2.0 arch/x86 include/asm-x86`,
+   `v1.0` and `v2.0` are revisions and `arch/x86` and `include/asm-x86`
+   are paths.
+
+ * When an argument can be misunderstood as either a revision or a path,
+   they can be disambiguated by placing `\--` between them.
+   E.g. `git diff \-- HEAD` is, "I have a file called HEAD in my work
+   tree.  Please show changes between the version I staged in the index
+   and what I have in the work tree for that file". not "show difference
+   between the HEAD commit and the work tree as a whole".  You can say
+   `git diff HEAD \--` to ask for the latter.
+
+ * Without disambiguating `\--`, git makes a reasonable guess, but errors
+   out and asking you to disambiguate when ambiguous.  E.g. if you have a
+   file called HEAD in your work tree, `git diff HEAD` is ambiguous, and
+   you have to say either `git diff HEAD \--` or `git diff \-- HEAD` to
+   disambiguate.
+
+When writing a script that is expected to handle random user-input, it is
+a good practice to make it explicit which arguments are which by placing
+disambiguating `\--` at appropriate places.
+
+Here are the rules regarding the "flags" that you should follow when you are
+scripting git:
 
  * it's preferred to use the non dashed form of git commands, which means that
    you should prefer `"git foo"` to `"git-foo"`.

+NOTES ON FREQUENTLY CONFUSED OPTIONS
+------------------------------------
+
+Many commands that can work on files in the working tree
+and/or in the index can take `--cached` and/or `--index`
+options.  Sometimes people incorrectly think that, because
+the index was originally called cache, these two are
+synonyms.  They are *not* -- these two options mean very
+different things.
+
+ * The `--cached` option is used to ask a command that
+   usually works on files in the working tree to *only* work
+   with the index.  For example, `git grep`, when used
+   without a commit to specify from which commit to look for
+   strings in, usually works on files in the working tree,
+   but with the `--cached` option, it looks for strings in
+   the index.
+
+ * The `--index` option is used to ask a command that
+   usually works on files in the working tree to *also*
+   affect the index.  For example, `git stash apply` usually
+   merges changes recorded in a stash to the working tree,
+   but with the `--index` option, it also merges changes to
+   the index as well.
+
+`git apply` command can be used with `--cached` and
+`--index` (but not at the same time).  Usually the command
+only affects the files in the working tree, but with
+`--index`, it patches both the files and their index
+entries, and with `--cached`, it modifies only the index
+entries.

+===============
+
+NAME
+----
+gitworkflows - An overview of recommended workflows with git
+
+SYNOPSIS
+--------
+git *
+
+
+DESCRIPTION
+-----------
+
+This document attempts to write down and motivate some of the workflow
+elements used for `git.git` itself.  Many ideas apply in general,
+though the full workflow is rarely required for smaller projects with
+fewer people involved.
+
+We formulate a set of 'rules' for quick reference, while the prose
+tries to motivate each of them.  Do not always take them literally;
+you should value good reasons for your actions higher than manpages
+such as this one.
+
+
+SEPARATE CHANGES
+----------------
+
+As a general rule, you should try to split your changes into small
+logical steps, and commit each of them.  They should be consistent,
+working independently of any later commits, pass the test suite, etc.
+This makes the review process much easier, and the history much more
+useful for later inspection and analysis, for example with
+linkgit:git-blame[1] and linkgit:git-bisect[1].
+
+To achieve this, try to split your work into small steps from the very
+beginning. It is always easier to squash a few commits together than
+to split one big commit into several.  Don't be afraid of making too
+small or imperfect steps along the way. You can always go back later
+and edit the commits with `git rebase \--interactive` before you
+publish them.  You can use `git stash save \--keep-index` to run the
+test suite independent of other uncommitted changes; see the EXAMPLES
+section of linkgit:git-stash[1].
+
+
+MANAGING BRANCHES
+-----------------
+
+There are two main tools that can be used to include changes from one
+branch on another: linkgit:git-merge[1] and
+linkgit:git-cherry-pick[1].
+
+Merges have many advantages, so we try to solve as many problems as
+possible with merges alone.  Cherry-picking is still occasionally
+useful; see "Merging upwards" below for an example.
+
+Most importantly, merging works at the branch level, while
+cherry-picking works at the commit level.  This means that a merge can
+carry over the changes from 1, 10, or 1000 commits with equal ease,
+which in turn means the workflow scales much better to a large number
+of contributors (and contributions).  Merges are also easier to
+understand because a merge commit is a "promise" that all changes from
+all its parents are now included.
+
+There is a tradeoff of course: merges require a more careful branch
+management.  The following subsections discuss the important points.
+
+
+Graduation
+~~~~~~~~~~
+
+As a given feature goes from experimental to stable, it also
+"graduates" between the corresponding branches of the software.
+`git.git` uses the following 'integration branches':
+
+* 'maint' tracks the commits that should go into the next "maintenance
+  release", i.e., update of the last released stable version;
+
+* 'master' tracks the commits that should go into the next release;
+
+* 'next' is intended as a testing branch for topics being tested for
+  stability for master.
+
+There is a fourth official branch that is used slightly differently:
+
+* 'pu' (proposed updates) is an integration branch for things that are
+  not quite ready for inclusion yet (see "Integration Branches"
+  below).
+
+Each of the four branches is usually a direct descendant of the one
+above it.
+
+Conceptually, the feature enters at an unstable branch (usually 'next'
+or 'pu'), and "graduates" to 'master' for the next release once it is
+considered stable enough.
+
+
+Merging upwards
+~~~~~~~~~~~~~~~
+
+The "downwards graduation" discussed above cannot be done by actually
+merging downwards, however, since that would merge 'all' changes on
+the unstable branch into the stable one.  Hence the following:
+
+.Merge upwards
+[caption="Rule: "]
+=====================================
+Always commit your fixes to the oldest supported branch that require
+them.  Then (periodically) merge the integration branches upwards into each
+other.
+=====================================
+
+This gives a very controlled flow of fixes.  If you notice that you
+have applied a fix to e.g. 'master' that is also required in 'maint',
+you will need to cherry-pick it (using linkgit:git-cherry-pick[1])
+downwards.  This will happen a few times and is nothing to worry about
+unless you do it very frequently.
+
+
+Topic branches
+~~~~~~~~~~~~~~
+
+Any nontrivial feature will require several patches to implement, and
+may get extra bugfixes or improvements during its lifetime.
+
+Committing everything directly on the integration branches leads to many
+problems: Bad commits cannot be undone, so they must be reverted one
+by one, which creates confusing histories and further error potential
+when you forget to revert part of a group of changes.  Working in
+parallel mixes up the changes, creating further confusion.
+
+Use of "topic branches" solves these problems.  The name is pretty
+self explanatory, with a caveat that comes from the "merge upwards"
+rule above:
+
+.Topic branches
+[caption="Rule: "]
+=====================================
+Make a side branch for every topic (feature, bugfix, ...). Fork it off
+at the oldest integration branch that you will eventually want to merge it
+into.
+=====================================
+
+Many things can then be done very naturally:
+
+* To get the feature/bugfix into an integration branch, simply merge
+  it.  If the topic has evolved further in the meantime, merge again.
+  (Note that you do not necessarily have to merge it to the oldest
+  integration branch first.  For example, you can first merge a bugfix
+  to 'next', give it some testing time, and merge to 'maint' when you
+  know it is stable.)
+
+* If you find you need new features from the branch 'other' to continue
+  working on your topic, merge 'other' to 'topic'.  (However, do not
+  do this "just habitually", see below.)
+
+* If you find you forked off the wrong branch and want to move it
+  "back in time", use linkgit:git-rebase[1].
+
+Note that the last point clashes with the other two: a topic that has
+been merged elsewhere should not be rebased.  See the section on
+RECOVERING FROM UPSTREAM REBASE in linkgit:git-rebase[1].
+
+We should point out that "habitually" (regularly for no real reason)
+merging an integration branch into your topics -- and by extension,
+merging anything upstream into anything downstream on a regular basis
+-- is frowned upon:
+
+.Merge to downstream only at well-defined points
+[caption="Rule: "]
+=====================================
+Do not merge to downstream except with a good reason: upstream API
+changes affect your branch; your branch no longer merges to upstream
+cleanly; etc.
+=====================================
+
+Otherwise, the topic that was merged to suddenly contains more than a
+single (well-separated) change.  The many resulting small merges will
+greatly clutter up history.  Anyone who later investigates the history
+of a file will have to find out whether that merge affected the topic
+in development.  An upstream might even inadvertently be merged into a
+"more stable" branch.  And so on.
+
+
+Throw-away integration
+~~~~~~~~~~~~~~~~~~~~~~
+
+If you followed the last paragraph, you will now have many small topic
+branches, and occasionally wonder how they interact.  Perhaps the
+result of merging them does not even work?  But on the other hand, we
+want to avoid merging them anywhere "stable" because such merges
+cannot easily be undone.
+
+The solution, of course, is to make a merge that we can undo: merge
+into a throw-away branch.
+
+.Throw-away integration branches
+[caption="Rule: "]
+=====================================
+To test the interaction of several topics, merge them into a
+throw-away branch.  You must never base any work on such a branch!
+=====================================
+
+If you make it (very) clear that this branch is going to be deleted
+right after the testing, you can even publish this branch, for example
+to give the testers a chance to work with it, or other developers a
+chance to see if their in-progress work will be compatible.  `git.git`
+has such an official throw-away integration branch called 'pu'.
+
+
+DISTRIBUTED WORKFLOWS
+---------------------
+
+After the last section, you should know how to manage topics.  In
+general, you will not be the only person working on the project, so
+you will have to share your work.
+
+Roughly speaking, there are two important workflows: merge and patch.
+The important difference is that the merge workflow can propagate full
+history, including merges, while patches cannot.  Both workflows can
+be used in parallel: in `git.git`, only subsystem maintainers use
+the merge workflow, while everyone else sends patches.
+
+Note that the maintainer(s) may impose restrictions, such as
+"Signed-off-by" requirements, that all commits/patches submitted for
+inclusion must adhere to.  Consult your project's documentation for
+more information.
+
+
+Merge workflow
+~~~~~~~~~~~~~~
+
+The merge workflow works by copying branches between upstream and
+downstream.  Upstream can merge contributions into the official
+history; downstream base their work on the official history.
+
+There are three main tools that can be used for this:
+
+* linkgit:git-push[1] copies your branches to a remote repository,
+  usually to one that can be read by all involved parties;
+
+* linkgit:git-fetch[1] that copies remote branches to your repository;
+  and
+
+* linkgit:git-pull[1] that does fetch and merge in one go.
+
+Note the last point.  Do 'not' use 'git-pull' unless you actually want
+to merge the remote branch.
+
+Getting changes out is easy:
+
+.Push/pull: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+`git push <remote> <branch>` and tell everyone where they can fetch
+from.
+=====================================
+
+You will still have to tell people by other means, such as mail.  (Git
+provides the linkgit:git-request-pull[1] to send preformatted pull
+requests to upstream maintainers to simplify this task.)
+
+If you just want to get the newest copies of the integration branches,
+staying up to date is easy too:
+
+.Push/pull: Staying up to date
+[caption="Recipe: "]
+=====================================
+Use `git fetch <remote>` or `git remote update` to stay up to date.
+=====================================
+
+Then simply fork your topic branches from the stable remotes as
+explained earlier.
+
+If you are a maintainer and would like to merge other people's topic
+branches to the integration branches, they will typically send a
+request to do so by mail.  Such a request looks like
+
+-------------------------------------
+Please pull from
+    <url> <branch>
+-------------------------------------
+
+In that case, 'git-pull' can do the fetch and merge in one go, as
+follows.
+
+.Push/pull: Merging remote topics
+[caption="Recipe: "]
+=====================================
+`git pull <url> <branch>`
+=====================================
+
+Occasionally, the maintainer may get merge conflicts when he tries to
+pull changes from downstream.  In this case, he can ask downstream to
+do the merge and resolve the conflicts themselves (perhaps they will
+know better how to resolve them).  It is one of the rare cases where
+downstream 'should' merge from upstream.
+
+
+Patch workflow
+~~~~~~~~~~~~~~
+
+If you are a contributor that sends changes upstream in the form of
+emails, you should use topic branches as usual (see above).  Then use
+linkgit:git-format-patch[1] to generate the corresponding emails
+(highly recommended over manually formatting them because it makes the
+maintainer's life easier).
+
+.format-patch/am: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+* `git format-patch -M upstream..topic` to turn them into preformatted
+  patch files
+* `git send-email --to=<recipient> <patches>`
+=====================================
+
+See the linkgit:git-format-patch[1] and linkgit:git-send-email[1]
+manpages for further usage notes.
+
+If the maintainer tells you that your patch no longer applies to the
+current upstream, you will have to rebase your topic (you cannot use a
+merge because you cannot format-patch merges):
+
+.format-patch/am: Keeping topics up to date
+[caption="Recipe: "]
+=====================================
+`git pull --rebase <url> <branch>`
+=====================================
+
+You can then fix the conflicts during the rebase.  Presumably you have
+not published your topic other than by mail, so rebasing it is not a
+problem.
+
+If you receive such a patch series (as maintainer, or perhaps as a
+reader of the mailing list it was sent to), save the mails to files,
+create a new topic branch and use 'git-am' to import the commits:
+
+.format-patch/am: Importing patches
+[caption="Recipe: "]
+=====================================
+`git am < patch`
+=====================================
+
+One feature worth pointing out is the three-way merge, which can help
+if you get conflicts: `git am -3` will use index information contained
+in patches to figure out the merge base.  See linkgit:git-am[1] for
+other options.

-	git branch broken
-
-	# Reset the main branch to three parents back: this

-
-Finally, check out the end result again:

-And then, you can just remove the broken branch if you decide you really

-
-	# remove 'broken' branch
-	git branch -d broken
-
-	# Prune old objects if you're really really sure

+From: Linus Torvalds <torvalds@linux-foundation.org>, Junio C Hamano <gitster@pobox.com>
+Subject: Re: Odd merge behaviour involving reverts
+Abstract: Sometimes a branch that was already merged to the mainline
+ is later found to be faulty.  Linus and Junio give guidance on
+ recovering from such a premature merge and continuing development
+ after the offending branch is fixed.
+Message-ID: <7vocz8a6zk.fsf@gitster.siamese.dyndns.org>
+References: <alpine.LFD.2.00.0812181949450.14014@localhost.localdomain>
+
+Alan <alan@clueserver.org> said:
+
+    I have a master branch.  We have a branch off of that that some
+    developers are doing work on.  They claim it is ready. We merge it
+    into the master branch.  It breaks something so we revert the merge.
+    They make changes to the code.  they get it to a point where they say
+    it is ok and we merge again.
+
+    When examined, we find that code changes made before the revert are
+    not in the master branch, but code changes after are in the master
+    branch.
+
+and asked for help recovering from this situation.
+
+The history immediately after the "revert of the merge" would look like
+this:
+
+ ---o---o---o---M---x---x---W
+	       /
+       ---A---B
+
+where A and B are on the side development that was not so good, M is the
+merge that brings these premature changes into the mainline, x are changes
+unrelated to what the side branch did and already made on the mainline,
+and W is the "revert of the merge M" (doesn't W look M upside down?).
+IOW, "diff W^..W" is similar to "diff -R M^..M".
+
+Such a "revert" of a merge can be made with:
+
+    $ git revert -m 1 M
+
+After the develpers of the side branch fixes their mistakes, the history
+may look like this:
+
+ ---o---o---o---M---x---x---W---x
+	       /
+       ---A---B-------------------C---D
+
+where C and D are to fix what was broken in A and B, and you may already
+have some other changes on the mainline after W.
+
+If you merge the updated side branch (with D at its tip), none of the
+changes made in A nor B will be in the result, because they were reverted
+by W.  That is what Alan saw.
+
+Linus explains the situation:
+
+    Reverting a regular commit just effectively undoes what that commit
+    did, and is fairly straightforward. But reverting a merge commit also
+    undoes the _data_ that the commit changed, but it does absolutely
+    nothing to the effects on _history_ that the merge had.
+
+    So the merge will still exist, and it will still be seen as joining
+    the two branches together, and future merges will see that merge as
+    the last shared state - and the revert that reverted the merge brought
+    in will not affect that at all.
+
+    So a "revert" undoes the data changes, but it's very much _not_ an
+    "undo" in the sense that it doesn't undo the effects of a commit on
+    the repository history.
+
+    So if you think of "revert" as "undo", then you're going to always
+    miss this part of reverts. Yes, it undoes the data, but no, it doesn't
+    undo history.
+
+In such a situation, you would want to first revert the previous revert,
+which would make the history look like this:
+
+ ---o---o---o---M---x---x---W---x---Y
+	       /
+       ---A---B-------------------C---D
+
+where Y is the revert of W.  Such a "revert of the revert" can be done
+with:
+
+    $ git revert W
+
+This history would (ignoring possible conflicts between what W and W..Y
+changed) be equivalent to not having W nor Y at all in the history:
+
+ ---o---o---o---M---x---x-------x----
+	       /
+       ---A---B-------------------C---D
+
+and merging the side branch again will not have conflict arising from an
+earlier revert and revert of the revert.
+
+ ---o---o---o---M---x---x-------x-------*
+	       /                       /
+       ---A---B-------------------C---D
+
+Of course the changes made in C and D still can conflict with what was
+done by any of the x, but that is just a normal merge conflict.
+
+On the other hand, if the developers of the side branch discarded their
+faulty A and B, and redone the changes on top of the updated mainline
+after the revert, the history would have looked like this:
+
+ ---o---o---o---M---x---x---W---x---x
+	       /                 \
+       ---A---B                   A'--B'--C'
+
+If you reverted the revert in such a case as in the previous example:
+
+ ---o---o---o---M---x---x---W---x---x---Y---*
+	       /                 \         /
+       ---A---B                   A'--B'--C'
+
+where Y is the revert of W, A' and B'are rerolled A and B, and there may
+also be a further fix-up C' on the side branch.  "diff Y^..Y" is similar
+to "diff -R W^..W" (which in turn means it is similar to "diff M^..M"),
+and "diff A'^..C'" by definition would be similar but different from that,
+because it is a rerolled series of the earlier change.  There will be a
+lot of overlapping changes that result in conflicts.  So do not do "revert
+of revert" blindly without thinking..
+
+ ---o---o---o---M---x---x---W---x---x
+	       /                 \
+       ---A---B                   A'--B'--C'
+
+In the history with rebased side branch, W (and M) are behind the merge
+base of the updated branch and the tip of the mainline, and they should
+merge without the past faulty merge and its revert getting in the way.
+
+To recap, these are two very different scenarios, and they want two very
+different resolution strategies:
+
+ - If the faulty side branch was fixed by adding corrections on top, then
+   doing a revert of the previous revert would be the right thing to do.
+
+ - If the faulty side branch whose effects were discarded by an earlier
+   revert of a merge was rebuilt from scratch (i.e. rebasing and fixing,
+   as you seem to have interpreted), then re-merging the result without
+   doing anything else fancy would be the right thing to do.
+
+However, there are things to keep in mind when reverting a merge (and
+reverting such a revert).
+
+For example, think about what reverting a merge (and then reverting the
+revert) does to bisectability. Ignore the fact that the revert of a revert
+is undoing it - just think of it as a "single commit that does a lot".
+Because that is what it does.
+
+When you have a problem you are chasing down, and you hit a "revert this
+merge", what you're hitting is essentially a single commit that contains
+all the changes (but obviously in reverse) of all the commits that got
+merged. So it's debugging hell, because now you don't have lots of small
+changes that you can try to pinpoint which _part_ of it changes.
+
+But does it all work? Sure it does. You can revert a merge, and from a
+purely technical angle, git did it very naturally and had no real
+troubles. It just considered it a change from "state before merge" to
+"state after merge", and that was it. Nothing complicated, nothing odd,
+nothing really dangerous. Git will do it without even thinking about it.
+
+So from a technical angle, there's nothing wrong with reverting a merge,
+but from a workflow angle it's something that you generally should try to
+avoid.
+
+If at all possible, for example, if you find a problem that got merged
+into the main tree, rather than revert the merge, try _really_ hard to
+bisect the problem down into the branch you merged, and just fix it, or
+try to revert the individual commit that caused it.
+
+Yes, it's more complex, and no, it's not always going to work (sometimes
+the answer is: "oops, I really shouldn't have merged it, because it wasn't
+ready yet, and I really need to undo _all_ of the merge"). So then you
+really should revert the merge, but when you want to re-do the merge, you
+now need to do it by reverting the revert.

+History Simplification
+~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes you are only interested in parts of the history, for example the
+commits modifying a particular <path>. But there are two parts of
+'History Simplification', one part is selecting the commits and the other
+is how to do it, as there are various strategies to simplify the history.
+
+The following options select the commits to be shown:
+
+<paths>::
+
+	Commits modifying the given <paths> are selected.
+
+--simplify-by-decoration::
+
+	Commits that are referred by some branch or tag are selected.
+
+Note that extra commits can be shown to give a meaningful history.
+
+The following options affect the way the simplification is performed:
+
+Default mode::
+
+	Simplifies the history to the simplest history explaining the
+	final state of the tree. Simplest because it prunes some side
+	branches if the end result is the same (i.e. merging branches
+	with the same content)
+
+--full-history::
+
+	As the default mode but does not prune some history.
+
 --dense::
+
+	Only the selected commits are shown, plus some to have a
+	meaningful history.
+
 --sparse::
 
-When optional paths are given, the default behaviour ('--dense') is to
-only output commits that changes at least one of them, and also ignore
-merges that do not touch the given paths.
+	All commits in the simplified history are shown.
+
+--simplify-merges::
+
+	Additional option to '--full-history' to remove some needless
+	merges from the resulting history, as there are no selected
+	commits contributing to this merge.
+
+A more detailed explanation follows.
+
+Suppose you specified `foo` as the <paths>.  We shall call commits
+that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
+filtered for `foo`, they look different and equal, respectively.)
+
+In the following, we will always refer to the same example history to
+illustrate the differences between simplification settings.  We assume
+that you are filtering for a file `foo` in this commit graph:
+-----------------------------------------------------------------------
+	  .-A---M---N---O---P
+	 /     /   /   /   /
+	I     B   C   D   E
+	 \   /   /   /   /
+	  `-------------'
+-----------------------------------------------------------------------
+The horizontal line of history A--P is taken to be the first parent of
+each merge.  The commits are:
+
+* `I` is the initial commit, in which `foo` exists with contents
+  "asdf", and a file `quux` exists with contents "quux".  Initial
+  commits are compared to an empty tree, so `I` is !TREESAME.
+
+* In `A`, `foo` contains just "foo".
+
+* `B` contains the same change as `A`.  Its merge `M` is trivial and
+  hence TREESAME to all parents.
+
+* `C` does not change `foo`, but its merge `N` changes it to "foobar",
+  so it is not TREESAME to any parent.
+
+* `D` sets `foo` to "baz".  Its merge `O` combines the strings from
+  `N` and `D` to "foobarbaz"; i.e., it is not TREESAME to any parent.
 
-Use the '--sparse' flag to makes the command output all eligible commits
-(still subject to count and age limitation), but apply merge
-simplification nevertheless.
+* `E` changes `quux` to "xyzzy", and its merge `P` combines the
+  strings to "quux xyzzy".  Despite appearing interesting, `P` is
+  TREESAME to all parents.
+
+'rev-list' walks backwards through history, including or excluding
+commits based on whether '\--full-history' and/or parent rewriting
+(via '\--parents' or '\--children') are used.  The following settings
+are available.
+
+Default mode::
+
+	Commits are included if they are not TREESAME to any parent
+	(though this can be changed, see '\--sparse' below).  If the
+	commit was a merge, and it was TREESAME to one parent, follow
+	only that parent.  (Even if there are several TREESAME
+	parents, follow only one of them.)  Otherwise, follow all
+	parents.
++
+This results in:
++
+-----------------------------------------------------------------------
+	  .-A---N---O
+	 /         /
+	I---------D
+-----------------------------------------------------------------------
++
+Note how the rule to only follow the TREESAME parent, if one is
+available, removed `B` from consideration entirely.  `C` was
+considered via `N`, but is TREESAME.  Root commits are compared to an
+empty tree, so `I` is !TREESAME.
++
+Parent/child relations are only visible with --parents, but that does
+not affect the commits selected in default mode, so we have shown the
+parent lines.
+
+--full-history without parent rewriting::
+
+	This mode differs from the default in one point: always follow
+	all parents of a merge, even if it is TREESAME to one of them.
+	Even if more than one side of the merge has commits that are
+	included, this does not imply that the merge itself is!  In
+	the example, we get
++
+-----------------------------------------------------------------------
+	I  A  B  N  D  O
+-----------------------------------------------------------------------
++
+`P` and `M` were excluded because they are TREESAME to a parent.  `E`,
+`C` and `B` were all walked, but only `B` was !TREESAME, so the others
+do not appear.
++
+Note that without parent rewriting, it is not really possible to talk
+about the parent/child relationships between the commits, so we show
+them disconnected.
+
+--full-history with parent rewriting::
+
+	Ordinary commits are only included if they are !TREESAME
+	(though this can be changed, see '\--sparse' below).
++
+Merges are always included.  However, their parent list is rewritten:
+Along each parent, prune away commits that are not included
+themselves.  This results in
++
+-----------------------------------------------------------------------
+	  .-A---M---N---O---P
+	 /     /   /   /   /
+	I     B   /   D   /
+	 \   /   /   /   /
+	  `-------------'
+-----------------------------------------------------------------------
++
+Compare to '\--full-history' without rewriting above.  Note that `E`
+was pruned away because it is TREESAME, but the parent list of P was
+rewritten to contain `E`'s parent `I`.  The same happened for `C` and
+`N`.  Note also that `P` was included despite being TREESAME.
+
+In addition to the above settings, you can change whether TREESAME
+affects inclusion:
+
+--dense::
+
+	Commits that are walked are included if they are not TREESAME
+	to any parent.
+
+--sparse::
+
+	All commits that are walked are included.
++
+Note that without '\--full-history', this still simplifies merges: if
+one of the parents is TREESAME, we follow only that one, so the other
+sides of the merge are never walked.
+
+Finally, there is a fourth simplification mode available:
+
+--simplify-merges::
+
+	First, build a history graph in the same way that
+	'\--full-history' with parent rewriting does (see above).
++
+Then simplify each commit `C` to its replacement `C'` in the final
+history according to the following rules:
++
+--
+* Set `C'` to `C`.
++
+* Replace each parent `P` of `C'` with its simplification `P'`.  In
+  the process, drop parents that are ancestors of other parents, and
+  remove duplicates.
++
+* If after this parent rewriting, `C'` is a root or merge commit (has
+  zero or >1 parents), a boundary commit, or !TREESAME, it remains.
+  Otherwise, it is replaced with its only parent.
+--
++
+The effect of this is best shown by way of comparing to
+'\--full-history' with parent rewriting.  The example turns into:
++
+-----------------------------------------------------------------------
+	  .-A---M---N---O
+	 /     /       /
+	I     B       D
+	 \   /       /
+	  `---------'
+-----------------------------------------------------------------------
++
+Note the major differences in `N` and `P` over '\--full-history':
++
+--
+* `N`'s parent list had `I` removed, because it is an ancestor of the
+  other parent `M`.  Still, `N` remained because it is !TREESAME.
++
+* `P`'s parent list similarly had `I` removed.  `P` was then
+  removed completely, because it had one parent and is TREESAME.
+--
+
+The '\--simplify-by-decoration' option allows you to view only the
+big picture of the topology of the history, by omitting commits
+that are not referenced by tags.  Commits are marked as !TREESAME
+(in other words, kept after history simplification rules described
+above) if (1) they are referenced by tags, or (2) they change the
+contents of the paths given on the command line.  All other
+commits are marked as TREESAME (subject to be simplified away).

-path-list API
-=============
-
-The path_list API offers a data structure and functions to handle sorted
-and unsorted string lists.
-
-The name is a bit misleading, a path_list may store not only paths but
-strings in general.
-
-The caller:
-
-. Allocates and clears a `struct path_list` variable.
-
-. Initializes the members. You might want to set the flag `strdup_paths`
-  if the strings should be strdup()ed. For example, this is necessary
-  when you add something like git_path("..."), since that function returns
-  a static buffer that will change with the next call to git_path().
-+
-If you need something advanced, you can manually malloc() the `items`
-member (you need this if you add things later) and you should set the
-`nr` and `alloc` members in that case, too.
-
-. Adds new items to the list, using `path_list_append` or `path_list_insert`.
-
-. Can check if a string is in the list using `path_list_has_path` or
-  `unsorted_path_list_has_path` and get it from the list using
-  `path_list_lookup` for sorted lists.
-
-. Can sort an unsorted list using `sort_path_list`.
-
-. Finally it should free the list using `path_list_clear`.
-
-Example:
-
-----
-struct path_list list;
-int i;
-
-memset(&list, 0, sizeof(struct path_list));
-path_list_append("foo", &list);
-path_list_append("bar", &list);
-for (i = 0; i < list.nr; i++)
-	printf("%s\n", list.items[i].path)
-----
-
-NOTE: It is more efficient to build an unsorted list and sort it
-afterwards, instead of building a sorted list (`O(n log n)` instead of
-`O(n^2)`).
-+
-However, if you use the list to check if a certain string was added
-already, you should not do that (using unsorted_path_list_has_path()),
-because the complexity would be quadratic again (but with a worse factor).

-Functions
----------
-
-* General ones (works with sorted and unsorted lists as well)
-
-`print_path_list`::
-
-	Dump a path_list to stdout, useful mainly for debugging purposes. It
-	can take an optional header argument and it writes out the
-	string-pointer pairs of the path_list, each one in its own line.
-
-`path_list_clear`::
-
-	Free a path_list. The `path` pointer of the items will be freed in case
-	the `strdup_paths` member of the path_list is set. The second parameter
-	controls if the `util` pointer of the items should be freed or not.
-
-* Functions for sorted lists only
-
-`path_list_has_path`::
-
-	Determine if the path_list has a given string or not.
-
-`path_list_insert`::
-
-	Insert a new element to the path_list. The returned pointer can be handy
-	if you want to write something to the `util` pointer of the
-	path_list_item containing the just added string.
-+
-Since this function uses xrealloc() (which die()s if it fails) if the
-list needs to grow, it is safe not to check the pointer. I.e. you may
-write `path_list_insert(...)->util = ...;`.
-
-`path_list_lookup`::
-
-	Look up a given string in the path_list, returning the containing
-	path_list_item. If the string is not found, NULL is returned.
-
-* Functions for unsorted lists only
-
-`path_list_append`::
-
-	Append a new string to the end of the path_list.
-
-`sort_path_list`::
-
-	Make an unsorted list sorted.
-
-`unsorted_path_list_has_path`::
-
-	It's like `path_list_has_path()` but for unsorted lists.
-+
-This function needs to look through all items, as opposed to its
-counterpart for sorted lists, which performs a binary search.
-
-Data structures
----------------
-
-* `struct path_list_item`
-
-Represents an item of the list. The `path` member is a pointer to the
-string, and you may use the `util` member for any purpose, if you want.
-
-* `struct path_list`
-
-Represents the list itself.
-
-. The array of items are available via the `items` member.
-. The `nr` member contains the number of items stored in the list.
-. The `alloc` member is used to avoid reallocating at every insertion.
-  You should not tamper with it.
-. Setting the `strdup_paths` member to 1 will strdup() the strings
-  before adding them, see above.

+appp.sh is a script that is supposed to be used together with ExternalEditor

+
+Usage:
+- Generate the patch with git format-patch.
+- Start writing a new e-mail in Thunderbird.
+- Press the external editor button (or Ctrl-E) to run appp.sh
+- Select the previosly generated patch file.
+- Finish editing the e-mail.
+
+Any text that is entered into the message editor before appp.sh is called
+will be moved to the section between the --- and the diffstat.
+
+All S-O-B:s and Cc:s in the patch will be added to the CC list.
+
+To set it up, just install External Editor and tell it to use appp.sh as the
+editor.
+
+Zenity is a required dependency.

-To syntax highlight git's commit messages, you need to:
-  1. Copy syntax/gitcommit.vim to vim's syntax directory:
-     $ mkdir -p $HOME/.vim/syntax
-     $ cp syntax/gitcommit.vim $HOME/.vim/syntax
-  2. Auto-detect the editing of git commit files:
-     $ cat >>$HOME/.vimrc <<'EOF'
-     autocmd BufNewFile,BufRead COMMIT_EDITMSG set filetype=gitcommit
-     EOF
+Syntax highlighting for git commit messages, config files, etc. is
+included with the vim distribution as of vim 7.2, and should work
+automatically.
+
+If you have an older version of vim, you can get the latest syntax
+files from the vim project:
+
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/git.vim
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitcommit.vim
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitconfig.vim
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitrebase.vim
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitsendemail.vim
+
+To install:
+
+  1. Copy these files to vim's syntax directory $HOME/.vim/syntax
+  2. To auto-detect the editing of various git-related filetypes:
+	$ cat >>$HOME/.vim/filetype.vim <<'EOF'
+	autocmd BufNewFile,BufRead *.git/COMMIT_EDITMSG    setf gitcommit
+	autocmd BufNewFile,BufRead *.git/config,.gitconfig setf gitconfig
+	autocmd BufNewFile,BufRead git-rebase-todo         setf gitrebase
+	autocmd BufNewFile,BufRead .msg.[0-9]*
+		\ if getline(1) =~ '^From.*# This line is ignored.$' |
+		\   setf gitsendemail |
+		\ endif
+	autocmd BufNewFile,BufRead *.git/**
+		\ if getline(1) =~ '^\x\{40\}\>\|^ref: ' |
+		\   setf git |

+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instead of having gitweb find repositories by scanning filesystem starting
+from $projectroot (or $projects_list, if it points to directory), you can
+provide list of projects by setting $projects_list to a text file with list
+of projects (and some additional info).  This file uses the following
+format:
+
+One record (for project / repository) per line, whitespace separated fields;
+does not support (at least for now) lines continuation (newline escaping).
+Leading and trailing whitespace are ignored, any run of whitespace can be
+used as field separator (rules for Perl's "split(' ', $line)").  Keyed by
+the first field, which is project name, i.e. path to repository GIT_DIR
+relative to $projectroot.  Fields use modified URI encoding, defined in
+RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
+(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
+being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
+percent-encoded).  Reserved characters are: '%' (used for encoding), '+'
+(can be used to encode SPACE), all whitespace characters as defined in Perl,
+including SP, TAB and LF, (used to separate fields in a record).
+
+Currently list of fields is
+ * <repository path>  - path to repository GIT_DIR, relative to $projectroot
+ * <repository owner> - displayed as repository owner, preferably full name,
+                        or email, or both
+
+You can additionally use $projects_list file to limit which repositories
+are visible, and together with $strict_export to limit access to
+repositories (see "Gitweb repositories" section in gitweb/INSTALL).

+ * This function implements the Damerau-Levenshtein algorithm to
+ * calculate a distance between strings.
+ *
+ * Basically, it says how many letters need to be swapped, substituted,
+ * deleted from, or added to string1, at least, to get string2.
+ *
+ * The idea is to build a distance matrix for the substrings of both
+ * strings.  To avoid a large space complexity, only the last three rows
+ * are kept in memory (if swaps had the same or higher cost as one deletion
+ * plus one insertion, only two rows would be needed).
+ *
+ * At any stage, "i + 1" denotes the length of the current substring of
+ * string1 that the distance is calculated for.
+ *
+ * row2 holds the current row, row1 the previous row (i.e. for the substring
+ * of string1 of length "i"), and row0 the row before that.
+ *
+ * In other words, at the start of the big loop, row2[j + 1] contains the
+ * Damerau-Levenshtein distance between the substring of string1 of length
+ * "i" and the substring of string2 of length "j + 1".
+ *
+ * All the big loop does is determine the partial minimum-cost paths.
+ *
+ * It does so by calculating the costs of the path ending in characters
+ * i (in string1) and j (in string2), respectively, given that the last
+ * operation is a substition, a swap, a deletion, or an insertion.
+ *
+ * This implementation allows the costs to be weighted:
+ *
+ * - w (as in "sWap")
+ * - s (as in "Substitution")
+ * - a (for insertion, AKA "Add")
+ * - d (as in "Deletion")
+ *
+ * Note that this algorithm calculates a distance _iff_ d == a.

+This function returns a hashref of refs stored in a given remote repository.
+The hash is in the format C<refname =\> hash>. For tags, the C<refname> entry
+contains the tag object while a C<refname^{}> entry gives the tagged objects.
+
+C<REPOSITORY> has the same meaning as the appropriate C<git-ls-remote>
+argument; either an URL or a remote name (if called on a repository instance).
+C<GROUPS> is an optional arrayref that can contain 'tags' to return all the
+tags and/or 'heads' to return all the heads. C<REFGLOB> is an optional array
+of strings containing a shell-like glob to further limit the refs returned in
+the hash; the meaning is again the same as the appropriate C<git-ls-remote>
+argument.
+
+This function may or may not be called on a repository instance. In the former
+case, remote names as defined in the repository are recognized as repository
+specifiers.

 Alternatively, it can take a prepared ident string (e.g. from the commit
 object) and just parse it.

+Attempts to retreive the temporary file mapped to the string C<NAME>. If an
+associated temp file has not been created this session or was closed, it is
+created, cached, and set for autoflush and binmode.
+
+Internally locks the file mapped to C<NAME>. This lock must be released with
+C<temp_release()> when the temp file is no longer needed. Subsequent attempts
+to retrieve temporary files mapped to the same C<NAME> while still locked will
+cause an error. This locking mechanism provides a weak guarantee and is not
+threadsafe. It does provide some error checking to help prevent temp file refs
+writing over one another.
+
+In general, the L<File::Handle> returned should not be closed by consumers as
+it defeats the purpose of this caching mechanism. If you need to close the temp
+file handle, then you should use L<File::Temp> or another temp file faculty
+directly. If a handle is closed and then requested again, then a warning will
+issue.

+referencing a locked temp file.
+
+Warns if an attempt is made to release a file that is not locked.
+
+The temp file will be truncated before being released. This can help to reduce
+disk I/O where the system is smart enough to detect the truncation while data
+is in the output buffers. Beware that after the temp file is released and
+truncated, any operations on that file may fail miserably until it is
+re-acquired. All contents are lost between each release and acquire mapped to

+
+Skipping Tests
+--------------
+
+In some environments, certain tests have no way of succeeding
+due to platform limitation, such as lack of 'unzip' program, or
+filesystem that do not allow arbitrary sequence of non-NUL bytes
+as pathnames.
+
+You should be able to say something like
+
+    $ GIT_SKIP_TESTS=t9200.8 sh ./t9200-git-cvsexport-commit.sh
+
+and even:
+
+    $ GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' make
+
+to omit such tests.  The value of the environment variable is a
+SP separated list of patterns that tells which tests to skip,
+and either can match the "t[0-9]{4}" part to skip the whole
+test, or t[0-9]{4} followed by ".$number" to say which
+particular test to skip.
+
+Note that some tests in the existing test suite rely on previous
+test item, so you cannot arbitrarily disable one and expect the
+remainder of test to check what the test originally was intended
+to check.
