 465 <div class="paragraph">
 466 <p>Data written to stdin of the specified <em>&lt;command&gt;</em> is assumed
 467 to be sent to a git:// server, git-upload-pack, git-receive-pack
 468 or git-upload-archive (depending on situation), and data read
 469 from stdout of &lt;command&gt; is assumed to be received from
 470 the same service.</p>

 557 <p>This remote helper is transparently used by Git when
 558 you use commands such as "git fetch &lt;URL&gt;", "git clone &lt;URL&gt;",
 559 , "git push &lt;URL&gt;" or "git remote add &lt;nick&gt; &lt;URL&gt;", where &lt;URL&gt;
 560 begins with <code>ext::</code>.  Examples:</p>
 561 </div>
 562 <div class="dlist">
 563 <dl>
 564 <dt class="hdlist1">"ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S <em>foo/repo</em>"</dt>
 565 <dd>
 566 <p>Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
 567 keypair and user as the user on the remote side. This avoids the need to
 568 edit .ssh/config.</p>
 569 </dd>
 570 <dt class="hdlist1">"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"</dt>
 571 <dd>
 572 <p>Represents repository with path /somerepo accessible over
 573 git protocol at the abstract namespace address /git-server.</p>
 574 </dd>
 575 <dt class="hdlist1">"ext::git-server-alias foo %G/repo"</dt>
 576 <dd>
 577 <p>Represents a repository with path /repo accessed using the
 578 helper program "git-server-alias foo".  The path to the
 579 repository and type of request are not passed on the command
 580 line but as part of the protocol stream, as usual with git://
 581 protocol.</p>
 582 </dd>
 583 <dt class="hdlist1">"ext::git-server-alias foo %G/repo %Vfoo"</dt>
 584 <dd>
 585 <p>Represents a repository with path /repo accessed using the
 586 helper program "git-server-alias foo".  The hostname for the
 587 remote server passed in the protocol stream will be "foo"
 588 (this allows multiple virtual Git servers to share a
 589 link-level address).</p>
