/**
 * Clone options structure
 *
 * Use zeros to indicate default settings.  It's easiest to use the
 * `GIT_CLONE_OPTIONS_INIT` macro:
 *
 *		git_clone_options opts = GIT_CLONE_OPTIONS_INIT;
 *
 * - `checkout_opts` is options for the checkout step.  To disable checkout,
 *   set the `checkout_strategy` to GIT_CHECKOUT_DEFAULT.
 * - `bare` should be set to zero to create a standard repo, non-zero for
 *   a bare repo
 * - `fetch_progress_cb` is optional callback for fetch progress. Be aware that
 *   this is called inline with network and indexing operations, so performance
 *   may be affected.
 * - `fetch_progress_payload` is payload for fetch_progress_cb
 *
 *   ** "origin" remote options: **
 * - `remote_name` is the name given to the "origin" remote.  The default is
 *   "origin".
 * - `pushurl` is a URL to be used for pushing.  NULL means use the fetch url.
 * - `fetch_spec` is the fetch specification to be used for fetching.  NULL
 *   results in the same behavior as GIT_REMOTE_DEFAULT_FETCH.
 * - `push_spec` is the fetch specification to be used for pushing.  NULL means
 *   use the same spec as for fetching.
 * - `cred_acquire_cb` is a callback to be used if credentials are required
 *   during the initial fetch.
 * - `cred_acquire_payload` is the payload for the above callback.
 * - `transport` is a custom transport to be used for the initial fetch.  NULL
 *   means use the transport autodetected from the URL.
 * - `remote_callbacks` may be used to specify custom progress callbacks for
 *   the origin remote before the fetch is initiated.
 * - `remote_autotag` may be used to specify the autotag setting before the
 *   initial fetch.  The default is GIT_REMOTE_DOWNLOAD_TAGS_ALL.
 * - `checkout_branch` gives the name of the branch to checkout. NULL means
 *   use the remote's HEAD.
