   8SYNOPSIS
   9--------
  10[verse]
  11git remote add <nick> "ext::<command>[ <arguments>...]"
  12
  13DESCRIPTION
  14-----------
  15This remote helper uses the specified '<command>' to connect
  16to a remote Git server.
  17
  18Data written to stdin of the specified '<command>' is assumed
  19to be sent to a git:// server, git-upload-pack, git-receive-pack
  20or git-upload-archive (depending on situation), and data read
  21from stdout of <command> is assumed to be received from
  22the same service.
  23
  24Command and arguments are separated by an unescaped space.
  25
  26The following sequences have a special meaning:
  27
  28'% '::
  29        Literal space in command or argument.
  30
  31'%%'::
  32        Literal percent sign.
  33
  34'%s'::
  35        Replaced with name (receive-pack, upload-pack, or
  36        upload-archive) of the service Git wants to invoke.
  37
  38'%S'::
  39        Replaced with long name (git-receive-pack,
  40        git-upload-pack, or git-upload-archive) of the service
  41        Git wants to invoke.
  42
  43'%G' (must be the first characters in an argument)::
  44        This argument will not be passed to '<command>'. Instead, it
  45        will cause the helper to start by sending git:// service requests to
  46        the remote side with the service field set to an appropriate value and
  47        the repository field set to rest of the argument. Default is not to send
  48        such a request.
  49+
  50This is useful if remote side is git:// server accessed over
  51some tunnel.
  52
  53'%V' (must be first characters in argument)::
  54        This argument will not be passed to '<command>'. Instead it sets
  55        the vhost field in the git:// service request (to rest of the argument).
  56        Default is not to send vhost in such request (if sent).
  57
  58ENVIRONMENT VARIABLES
  59---------------------
  60
  61GIT_TRANSLOOP_DEBUG::
  62        If set, prints debugging information about various reads/writes.
  63
  64ENVIRONMENT VARIABLES PASSED TO COMMAND
  65---------------------------------------
  66
  67GIT_EXT_SERVICE::
  68        Set to long name (git-upload-pack, etc...) of service helper needs
  69        to invoke.
  70
  71GIT_EXT_SERVICE_NOPREFIX::
  72        Set to long name (upload-pack, etc...) of service helper needs
  73        to invoke.

  76EXAMPLES
  77--------
  78This remote helper is transparently used by Git when
  79you use commands such as "git fetch <URL>", "git clone <URL>",
  80, "git push <URL>" or "git remote add <nick> <URL>", where <URL>
  81begins with `ext::`.  Examples:
  82
  83"ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S 'foo/repo'"::
  84        Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
  85        keypair and user as user on remote side. This avoids needing to
  86        edit .ssh/config.
  87
  88"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
  89        Represents repository with path /somerepo accessible over
  90        git protocol at abstract namespace address /git-server.
  91
  92"ext::git-server-alias foo %G/repo"::
  93        Represents a repository with path /repo accessed using the
  94        helper program "git-server-alias foo".  The path to the
  95        repository and type of request are not passed on the command
  96        line but as part of the protocol stream, as usual with git://
  97        protocol.
  98
  99"ext::git-server-alias foo %G/repo %Vfoo"::
 100        Represents a repository with path /repo accessed using the
 101        helper program "git-server-alias foo".  The hostname for the
 102        remote server passed in the protocol stream will be "foo"
 103        (this allows multiple virtual Git servers to share a
 104        link-level address).
 105
 106"ext::git-server-alias foo %G/repo% with% spaces %Vfoo"::
 107        Represents a repository with path '/repo with spaces' accessed
 108        using the helper program "git-server-alias foo".  The hostname for
 109        the remote server passed in the protocol stream will be "foo"
 110        (this allows multiple virtual Git servers to share a
 111        link-level address).
 112
 113"ext::git-ssl foo.example /bar"::
 114        Represents a repository accessed using the helper program
 115        "git-ssl foo.example /bar".  The type of request can be
 116        determined by the helper using environment variables (see
 117        above).
