Retire git-clone-pack
The program is not used by git-clone since git-fetch-pack was extended to allow its caller do what git-clone-pack alone did, and git-clone was updated to use it. Signed-off-by: Junio C Hamano <junkio@cox.net>

git-clone-pack(1)

=================

|

NAME
|
||||
----
|
||||
git-clone-pack - Clones a repository by receiving packed objects
|
||||
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
'git-clone-pack' [--exec=<git-upload-pack>] [<host>:]<directory> [<head>...]
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
Clones a repository into the current repository by invoking
|
||||
'git-upload-pack', possibly on the remote host via ssh, in
|
||||
the named repository, and stores the sent pack in the local
|
||||
repository.
|
||||
|
||||
OPTIONS
|
||||
-------
|
||||
--exec=<git-upload-pack>::
|
||||
Use this to specify the path to 'git-upload-pack' on the
|
||||
remote side, if it is not found on your $PATH.
|
||||
Installations of sshd ignore the user's environment
|
||||
setup scripts for login shells (e.g. .bash_profile) and
|
||||
your privately installed git may not be found on the system
|
||||
default $PATH. Another workaround suggested is to set
|
||||
up your $PATH in ".bashrc", but this flag is for people
|
||||
who do not want to pay the overhead for non-interactive
|
||||
shells by having a lean .bashrc file (they set most of
|
||||
the things up in .bash_profile).
|
||||
|
||||
<host>::
|
||||
A remote host that houses the repository. When this
|
||||
part is specified, 'git-upload-pack' is invoked via
|
||||
ssh.
|
||||
|
||||
<directory>::
|
||||
The repository to sync from.
|
||||
|
||||
<head>...::
|
||||
The heads to update. This is relative to $GIT_DIR
|
||||
(e.g. "HEAD", "refs/heads/master"). When unspecified,
|
||||
all heads are updated to match the remote repository.
|
||||
+
|
||||
Usually all the refs from existing repository are stored
|
||||
under the same name in the new repository. Giving explicit
|
||||
<head> arguments instead writes the object names and refs to
|
||||
the standard output, just like get-fetch-pack does.
