NAME
       git-remote-ext - Bridge smart transport to external command.

SYNOPSIS
       git remote add  "ext::[ ...]"

DESCRIPTION
       This remote helper uses the specified  to connect to a remote Git server.

       Data written to stdin of the specified  is assumed to be sent to a git:// server,
       git-upload-pack, git-receive-pack or git-upload-archive (depending on situation), and data read from
       stdout of  is assumed to be received from the same service.

       Command and arguments are separated by an unescaped space.

       The following sequences have a special meaning:

       '% '
	   Literal space in command or argument.

       %%
	   Literal percent sign.

       %s
	   Replaced with name (receive-pack, upload-pack, or upload-archive) of the service Git wants to
	   invoke.

       %S
	   Replaced with long name (git-receive-pack, git-upload-pack, or git-upload-archive) of the service
	   Git wants to invoke.

       %G (must be the first characters in an argument)
	   This argument will not be passed to . Instead, it will cause the helper to start by
	   sending git:// service requests to the remote side with the service field set to an appropriate
	   value and the repository field set to the rest of the argument. Default is not to send such a
	   request.

	   This is useful if the remote side is git:// server accessed over some tunnel.

       %V (must be first characters in argument)
	   This argument will not be passed to . Instead it sets the vhost field in the git://
	   service request (to the rest of the argument). Default is not to send vhost in such request (if
	   sent).

ENVIRONMENT VARIABLES
       GIT_TRANSLOOP_DEBUG
	   If set, prints debugging information about various reads/writes.

ENVIRONMENT VARIABLES PASSED TO COMMAND
       GIT_EXT_SERVICE
	   Set to long name (git-upload-pack, etc...) of service helper needs to invoke.

       GIT_EXT_SERVICE_NOPREFIX
	   Set to long name (upload-pack, etc...) of service helper needs to invoke.

EXAMPLES
       This remote helper is transparently used by Git when you use commands such as "git fetch ", "git
       clone ", , "git push " or "git remote add  ", where  begins with ext::.
       Examples:

       "ext::ssh -i /home/foo/.ssh/somekey user@host.example %S foo/repo"
	   Like host.example:foo/repo, but use /home/foo/.ssh/somekey as keypair and user as the user on the
	   remote side. This avoids the need to edit .ssh/config.

       "ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"
	   Represents repository with path /somerepo accessible over git protocol at the abstract namespace
	   address /git-server.

       "ext::git-server-alias foo %G/repo"
	   Represents a repository with path /repo accessed using the helper program "git-server-alias foo".
	   The path to the repository and type of request are not passed on the command line but as part of
	   the protocol stream, as usual with git:// protocol.

       "ext::git-server-alias foo %G/repo %Vfoo"
	   Represents a repository with path /repo accessed using the helper program "git-server-alias foo".
	   The hostname for the remote server passed in the protocol stream will be "foo" (this allows
	   multiple virtual Git servers to share a link-level address).

       "ext::git-server-alias foo %G/repo% with% spaces %Vfoo"
	   Represents a repository with path /repo with spaces accessed using the helper program
	   "git-server-alias foo". The hostname for the remote server passed in the protocol stream will be
	   "foo" (this allows multiple virtual Git servers to share a link-level address).

       "ext::git-ssl foo.example /bar"
	   Represents a repository accessed using the helper program "git-ssl foo.example /bar". The type of
	   request can be determined by the helper using environment variables (see above).
