+NAME
+----
+git-archive - Creates a archive of the files in the named tree
+
+
+SYNOPSIS
+--------
+'git-archive' --format=<fmt> [--list] [--prefix=<prefix>/] [<extra>]
+ [--remote=<repo>] <tree-ish> [path...]
+
+DESCRIPTION
+-----------
+Creates an archive of the specified format containing the tree
+structure for the named tree. 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 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', 'zip'...
+
+--list::
+ Show all available formats.
+
+--prefix=<prefix>/::
+ Prepend <prefix>/ to each filename in the archive.
+
+<extra>::
+ This can be any options that the archiver backend understand.
+
+--remote=<repo>::
+ Instead of making a tar archive from local repository,
+ retrieve a tar archive from a remote repository.
+
+<tree-ish>::
+ The tree or commit to produce an archive for.
+
+path::
+ If one or more paths are specified, include only these in the
+ archive, otherwise include all files and subdirectories.
+
+CONFIGURATION
+-------------
+By default, file and directories modes are set to 0666 or 0777 in tar
+archives. It is possible to change this by setting the "umask" variable
+in the repository configuration as follows :
+
+[tar]
+ umask = 002 ;# group friendly
+
+The special umask value "user" indicates that the user's current umask
+will be used instead. The default value remains 0, which means world
+readable/writable files and directories.
+
+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 extracts it in
+ `/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 --prefix=git-1.4.0/ v1.4.0{caret}\{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/'.

+NAME

+
+SYNOPSIS
+--------
+'git-upload-archive' <directory>
+
+DESCRIPTION
+-----------
+Invoked by 'git-archive --remote' and sends a generated 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-archive' side, and the program pair
+is meant to be used to get an archive from a remote repository.
+
