** COMMAND: open
**
** Usage: %fossil open ?OPTIONS? ?--? FILENAME ?VERSION?
**
** Open a connection to the local repository in FILENAME.  A checkout
** for the repository is created with its root at the working directory.
** If VERSION is specified then that version is checked out.  Otherwise
** the latest version is checked out.  No files other than "manifest"
** and "manifest.uuid" are modified if the --keep option is present.
**
** Options:
**   --empty           Initialize checkout as being empty, but still connected
**                     with the local repository. If you commit this checkout,
**                     it will become a new "initial" commit in the repository.
**   --keep            Only modify the manifest and manifest.uuid files
**   --nested          Allow opening a repository inside an opened checkout
**   --force-missing   Force opening a repository with missing content
**   --setmtime        Set timestamps of all files to match their SCM-side
**                     times (the timestamp of the last checkin which modified
