 * - `checkout_opts` are option passed to the checkout step.  To disable

 *   Generally you will want the use GIT_CHECKOUT_SAFE_CREATE to create
 *   all files in the working directory for the newly cloned repository.
 * - `bare` should be set to zero (false) to create a standard repo,
 *   or non-zero for a bare repo
 * - `ignore_cert_errors` should be set to 1 if errors validating the
 *   remote host's certificate should be ignored.
 *
 *   ** "origin" remote options: **
 *
 * - `remote_name` is the name to be given to the "origin" remote.  The
 *   default is "origin".
 * - `checkout_branch` gives the name of the branch to checkout.  NULL
 *   means use the remote's HEAD.
 * - `signature` is the identity used when updating the reflog. NULL means to
 *   use the default signature using the config.
