var cmdClone = &Command{
Run: clone,
GitExtension: true,
Usage: "clone [-p] [<OPTIONS>] [<USER>/]<REPOSITORY> [<DESTINATION>]",
Long: `Clone a repository from GitHub.
## Options:
-p
(Deprecated) Clone private repositories over SSH.
[<USER>/]<REPOSITORY>
<USER> defaults to your own GitHub username.
<DESTINATION>
Directory name to clone into (default: <REPOSITORY>).
## Protocol used for cloning
HTTPS protocol is used by hub as the default. Alternatively, hub can be
configured to use SSH protocol for all git operations. See "SSH instead
of HTTPS protocol" and "HUB_PROTOCOL" of hub(1).
## Examples:
$ hub clone rtomayko/ronn
> git clone https://github.com/rtomayko/ronn.git

hub-fork(1), hub(1), git-clone(1)
