**   --keep            Only modify the manifest and manifest.uuid files
**   --nested          Allow opening a repository inside an opened checkout
**   --repodir DIR     If REPOSITORY is a URI that will be cloned, store
**                     the clone in DIR rather than in "."
**   --setmtime        Set timestamps of all files to match their SCM-side
**                     times (the timestamp of the last checkin which modified
**                     them).
**   --symlinks        Allow the use of symbolic links when expanding files
**                     in this check-out, overriding the global allow-symlinks
**                     setting (which default to "off").  CAUTION: This option
**                     might allow a malicious repository to overwrite files
**                     outside of the checkout directory.  This option is a
**                     security risk and its use is discouraged.
**   --workdir DIR     Use DIR as the working directory instead of ".". The DIR
**                     directory is created if it does not exist.
