+git-http-fetch(1)
+=================
+
+NAME
+----
+git-http-fetch - Download from a remote Git repository via HTTP
+
+
+SYNOPSIS
+--------
+[verse]
+'git http-fetch' [-c] [-t] [-a] [-d] [-v] [-w <filename>] [--recover] [--stdin | --packfile=<hash> | <commit>] <URL>
+
+DESCRIPTION
+-----------
+Downloads a remote Git repository via HTTP.
+
+This command always gets all objects. Historically, there were three options
+`-a`, `-c` and `-t` for choosing which objects to download. They are now
+silently ignored.
+
+OPTIONS
+-------
+commit-id::
+        Either the hash or the filename under [URL]/refs/ to
+        pull.
+
+-a, -c, -t::
+	These options are ignored for historical reasons.
+-v::
+	Report what is downloaded.
+
+-w <filename>::
+	Writes the commit-id into the specified filename under $GIT_DIR/refs/<filename> on
+        the local end after the transfer is complete.
+
+--stdin::
+	Instead of a commit id on the command line (which is not expected in this
+	case), 'git http-fetch' expects lines on stdin in the format
+
+		<commit-id>['\t'<filename-as-in--w>]
+
+--packfile=<hash>::
+	For internal use only. Instead of a commit id on the command
+	line (which is not expected in
+	this case), 'git http-fetch' fetches the packfile directly at the given
+	URL and uses index-pack to generate corresponding .idx and .keep files.
+	The hash is used to determine the name of the temporary file and is
+	arbitrary. The output of index-pack is printed to stdout. Requires
+	--index-pack-args.
+
+--index-pack-args=<args>::
+	For internal use only. The command to run on the contents of the
+	downloaded pack. Arguments are URL-encoded separated by spaces.
+
+--recover::
+	Verify that everything reachable from target is fetched.  Used after
+	an earlier fetch is interrupted.
