+NAME
+----
+git-archive - Create an archive of files from a named tree
+
+
+SYNOPSIS
+--------
+[verse]
+'git archive' [--format=<fmt>] [--list] [--prefix=<prefix>/] [<extra>]
+	      [-o <file> | --output=<file>] [--worktree-attributes]
+	      [--remote=<repo> [--exec=<git-upload-archive>]] <tree-ish>
+	      [<path>...]
+
+DESCRIPTION
+-----------
+Creates an archive of the specified format containing the tree
+structure for the named tree, and writes it out to the standard
+output.  If <prefix> is specified it is
+prepended to the filenames in the archive.
+
+'git archive' 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 the 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 in a global
+extended pax header if the tar format is used; it can be extracted
+using 'git get-tar-commit-id'. In ZIP files it is stored as a file
+comment.
+
+OPTIONS
+-------
+
+--format=<fmt>::
+	Format of the resulting archive: 'tar' or 'zip'. If this option
+	is not given, and the output file is specified, the format is
+	inferred from the filename if possible (e.g. writing to "foo.zip"
+	makes the output to be in the zip format). Otherwise the output
+	format is `tar`.
+
+-l::
+--list::
+	Show all available formats.
+
+-v::
+--verbose::
+	Report progress to stderr.
+
+--prefix=<prefix>/::
+	Prepend <prefix>/ to each filename in the archive.
+
+-o <file>::
+--output=<file>::
+	Write the archive to <file> instead of stdout.
+
+--worktree-attributes::
+	Look for attributes in .gitattributes files in the working tree
+	as well (see <<ATTRIBUTES>>).
+
+<extra>::
+	This can be any options that the archiver backend understands.
+	See next section.
+
+--remote=<repo>::
+	Instead of making a tar archive from the local repository,
+	retrieve a tar archive from a remote repository. Note that the
+	remote repository may place restrictions on which sha1
+	expressions may be allowed in `<tree-ish>`. See
+	linkgit:git-upload-archive[1] for details.
+
+--exec=<git-upload-archive>::
+	Used with --remote to specify the path to the
+	'git-upload-archive' on the remote side.
+
+<tree-ish>::
+	The tree or commit to produce an archive for.
+
+<path>::
+	Without an optional path parameter, all files and subdirectories
+	of the current working directory are included in the archive.
+	If one or more paths are specified, only these are included.
+
+BACKEND EXTRA OPTIONS
+---------------------
+
+zip
+~~~
+-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.
+
+
+CONFIGURATION
+-------------
+
+tar.umask::
+	This variable can be used to restrict the permission bits of
+	tar archive entries.  The default is 0002, which turns off the
+	world write bit.  The special value "user" indicates that the
+	archiving user's umask will be used instead.  See umask(2) for
+	details.  If `--remote` is used then only the configuration of
+	the remote repository takes effect.
+
+tar.<format>.command::
+	This variable specifies a shell command through which the tar
+	output generated by `git archive` should be piped. The command
+	is executed using the shell with the generated tar file on its
+	standard input, and should produce the final output on its
+	standard output. Any compression-level options will be passed
+	to the command (e.g., "-9"). An output file with the same
+	extension as `<format>` will be use this format if no other
+	format is given.
++
+The "tar.gz" and "tgz" formats are defined automatically and default to
+`gzip -cn`. You may override them with custom commands.
+
+tar.<format>.remote::
+	If true, enable `<format>` for use by remote clients via
+	linkgit:git-upload-archive[1]. Defaults to false for
+	user-defined formats, but true for the "tar.gz" and "tgz"
+	formats.
+
+[[ATTRIBUTES]]
+ATTRIBUTES
+----------
+
+export-ignore::
+	Files and directories with the attribute export-ignore won't be
+	added to archive files.  See linkgit:gitattributes[5] for details.
+
+export-subst::
+	If the attribute export-subst is set for a file then Git will
+	expand several placeholders when adding this file to an archive.
+	See linkgit:gitattributes[5] for details.
+
+Note that attributes are by default taken from the `.gitattributes` files
+in the tree that is being archived.  If you want to tweak the way the
+output is generated after the fact (e.g. you committed without adding an
+appropriate export-ignore in its `.gitattributes`), adjust the checked out
+`.gitattributes` file as necessary and use `--worktree-attributes`
+option.  Alternatively you can keep necessary attributes that should apply
+while archiving any tree in your `$GIT_DIR/info/attributes` file.
+
+EXAMPLES
+--------
+`git archive --format=tar --prefix=junk/ HEAD | (cd /var/tmp/ && tar xf -)`::
+
+	Create a tar archive that contains the contents of the
+	latest commit on the current branch, and extract it in the
+	`/var/tmp/junk` directory.
+
+`git archive --format=tar --prefix=git-1.4.0/ v1.4.0 | gzip >git-1.4.0.tar.gz`::
+
+	Create a compressed tarball for v1.4.0 release.
+
+`git archive --format=tar.gz --prefix=git-1.4.0/ v1.4.0 >git-1.4.0.tar.gz`::
+
+	Same as above, but using the builtin tar.gz handling.
+
+`git archive --prefix=git-1.4.0/ -o git-1.4.0.tar.gz v1.4.0`::
+
+	Same as above, but the format is inferred from the output file.
+
+`git archive --format=tar --prefix=git-1.4.0/ v1.4.0^{tree} | gzip >git-1.4.0.tar.gz`::
+
+	Create a compressed tarball for v1.4.0 release, but without a
+	global extended pax header.
+
+`git archive --format=zip --prefix=git-docs/ HEAD:Documentation/ > git-1.4.0-docs.zip`::
+
+	Put everything in the current head's Documentation/ directory
+	into 'git-1.4.0-docs.zip', with the prefix 'git-docs/'.
+
+`git archive -o latest.zip HEAD`::
+
+	Create a Zip archive that contains the contents of the latest
+	commit on the current branch. Note that the output format is
+	inferred by the extension of the output file.
+
+`git config tar.tar.xz.command "xz -c"`::
+
+	Configure a "tar.xz" format for making LZMA-compressed tarfiles.
+	You can use it specifying `--format=tar.xz`, or by creating an
+	output file like `-o foo.tar.xz`.
