     Use 'hg clone -u . src dst' to checkout the source repository's
     parent changeset (applicable for local source repositories only).
 
     A set of changesets (tags, or branch names) to pull may be specified
     by listing each changeset (tag, or branch name) with -r/--rev.
     If -r/--rev is used, the cloned repository will contain only a subset
     of the changesets of the source repository. Only the set of changesets
     defined by all -r/--rev options (including all their ancestors)
     will be pulled into the destination repository.
     No subsequent changesets (including subsequent tags) will be present
     in the destination.
 
     Using -r/--rev (or 'clone src#rev dest') implies --pull, even for
     local source repositories.
 
     For efficiency, hardlinks are used for cloning whenever the source
     and destination are on the same filesystem (note this applies only
     to the repository data, not to the checked out files). Some
     filesystems, such as AFS, implement hardlinking incorrectly, but
     do not report errors. In these cases, use the --pull option to
     avoid hardlinking.
 
     In some cases, you can clone repositories and checked out files
     using full hardlinks with ::
 
       $ cp -al REPO REPOCLONE
 
     This is the fastest way to clone, but it is not always safe. The
     operation is not atomic (making sure REPO is not modified during
     the operation is up to you) and you have to make sure your editor
     breaks hardlinks (Emacs and most Linux Kernel tools do so). Also,
     this is not compatible with certain extensions that place their
     metadata under the .hg directory, such as mq.

     This restores the contents of the affected files to an unmodified
     state and unschedules adds, removes, copies, and renames. If the
     working directory has two parents, you must explicitly specify the
     revision to revert to.

     to "roll back" some or all of an earlier change. See 'hg help
     dates' for a list of formats valid for -d/--date.
 
     Revert modifies the working directory. It does not commit any
     changes, or change the parent of the working directory. If you
     revert to a revision other than the parent of the working
     directory, the reverted files will thus appear modified
     afterwards.
 
     If a file has been deleted, it is restored. If the executable mode
     of a file was changed, it is reset.
 
     If names are given, all files matching the names are reverted.
     If no arguments are given, no files are reverted.

     any dirstate changes since that time. This command does not alter

     Transactions are used to encapsulate the effects of all commands
     that create new changesets or propagate existing changesets into a

     - unbundle
 
     This command is not intended for use on public repositories. Once

     back locally is ineffective (someone else may already have pulled
     the changes). Furthermore, a race is possible with readers of the
