This command implements the git archive protocol on the server
side. This command is not intended to be used by the end user.
Underlying git-archive command line options are sent over the
protocol from "git-archive --remote=...", just like upload-tar
currently does with "git-tar-tree=...".
As for "git-archive" command implementation, this new command
does not execute any existing "git-{tar,zip}-tree" but rely
on the archive API defined by "git-archive" patch. Hence we
get 2 good points:
- "git-archive" and "git-upload-archive" share all option
parsing code.
- All kind of git-upload-{tar,zip} could be removed.

+====================
+
+NAME
+----
+git-upload-archive - Send archive
+
+
+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.
+
+OPTIONS
+-------
+<directory>::
+ The repository to get a tar archive from.
+
+Author
+------
+Written by Franck Bui-Huu.
+
+Documentation
+--------------
