Tells `git-apply` how to handle whitespaces, in the same way
as the '--whitespace' option. See gitlink:git-apply[1].
+branch.<name>.remote::
+ When in branch <name>, it tells `git fetch` which remote to fetch.
+
+branch.<name>.merge::
+ When in branch <name>, it tells `git fetch` the default remote branch
+ to be merged.
+
pager.color::
A boolean to enable/disable colored output when the pager is in
use (default is true).

[--reuseaddr] [--detach] [--pid-file=file]
'git://example.com/hello.git', `git-daemon` will interpret the path
as '/srv/git/hello.git'.
+--interpolated-path=pathtemplate::
+ To support virtual hosting, an interpolated path template can be
+ used to dynamically construct alternate paths. The template
+ supports %H for the target hostname as supplied by the client,
+ and %D for the absolute path of the named repository.
+
--export-all::
Allow pulling from all directories that look like GIT repositories
(have the 'objects' and 'refs' subdirectories), even if they
disable it by setting `daemon.uploadpack` configuration
item to `false`.
+EXAMPLES
+--------
+git-daemon as inetd server::
+ To set up `git-daemon` as an inetd service that handles any
+ repository under the whitelisted set of directories, /pub/foo
+ and /pub/bar, place an entry like the following into
+ /etc/inetd all on one line:
++
+------------------------------------------------
+ git stream tcp nowait nobody /usr/bin/git-daemon
+ git-daemon --inetd --verbose
+ --syslog --export-all
+ /pub/foo /pub/bar
+------------------------------------------------
+
+
+git-daemon as inetd server for virtual hosts::
+ To set up `git-daemon` as an inetd service that handles
+ repositories for different virtual hosts, `www.example.com`
+ and `www.example.org`, place an entry like the following into
+ `/etc/inetd` all on one line:
++
+------------------------------------------------
+ git stream tcp nowait nobody /usr/bin/git-daemon
+ git-daemon --inetd --verbose
+ --syslog --export-all
+ --interpolated-path=/pub/%H%D
+ /pub/www.example.org/software
+ /pub/www.example.com/software
+ /software
+------------------------------------------------
++
+In this example, the root-level directory `/pub` will contain
+a subdirectory for each virtual host name supported.
+Further, both hosts advertise repositories simply as
+`git://www.example.com/software/repo.git`. For pre-1.4.0
+clients, a symlink from `/software` into the appropriate
+default repository could be made as well.

DESCRIPTION
-----------
+THIS COMMAND IS DEPRECATED. Use `git-archive` with `--format=tar`
+option instead.
+
Creates a tar archive containing the tree structure for the named tree.
When <base> is specified it is added as a leading path to the files in the
generated tar archive.

-=================
-
-NAME
-----
-git-upload-tar - Send tar archive
-
-
-SYNOPSIS
---------
-'git-upload-tar' <directory>
-
-DESCRIPTION
------------
-Invoked by 'git-tar-tree --remote' and sends a generated tar archive
-to the other end over the git protocol.
-
-This command is usually not invoked directly by the end user.
-The UI for the protocol is on the 'git-tar-tree' side, and the
-program pair is meant to be used to get a tar archive from a
-remote repository.
-
-
-OPTIONS
--------
-<directory>::
- The repository to get a tar archive from.

-git-zip-tree(1)
-===============
-
-NAME
-----
-git-zip-tree - Creates a ZIP archive of the files in the named tree
-
-
-SYNOPSIS
---------
-'git-zip-tree' [-0|...|-9] <tree-ish> [ <base> ]
-
-DESCRIPTION
------------
-Creates a ZIP archive containing the tree structure for the named tree.
-When <base> is specified it is added as a leading path to the files in the
-generated ZIP archive.
-
-git-zip-tree behaves differently when given a tree ID versus when given
-a commit ID or tag ID. In the first case the current time is used as
-modification time of each file in the archive. In the latter case the
-commit time as recorded in the referenced commit object is used instead.
-Additionally the commit ID is stored as an archive comment.
-
-Currently git-zip-tree can handle only files and directories, symbolic
-links are not supported.
-
-OPTIONS
--------
-
--0::
- Store the files instead of deflating them.
-
--9::
- Highest and slowest compression level. You can specify any
- number from 1 to 9 to adjust compression speed and ratio.
-
-<tree-ish>::
- The tree or commit to produce ZIP archive for. If it is
- the object name of a commit object.
-
-<base>::
- Leading path to the files in the resulting ZIP archive.
-
-EXAMPLES
---------
-git zip-tree v1.4.0 git-1.4.0 >git-1.4.0.zip::
-
- Create a ZIP file for v1.4.0 release.
-
-git zip-tree HEAD:Documentation/ git-docs >docs.zip::
-
- Put everything in the current head's Documentation/ directory
- into 'docs.zip', with the prefix 'git-docs/'.
