Fossil

**   --nested          Allow opening a repository inside an opened checkout
**   --nosync          Do not auto-sync the repository prior to opening
**   --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).
**   --verbose         If passed a URI then this flag is passed on to the clone
**                     operation, otherwise it has no effect.
**   --workdir DIR     Use DIR as the working directory instead of ".". The DIR
**                     directory is created if it does not exist.
