/*
** COMMAND: merge
**
** Usage: %fossil merge ?OPTIONS? ?VERSION?
**
** The argument VERSION is a version that should be merged into the
** current checkout. All changes from VERSION back to the nearest
** common ancestor are merged. Except, if either of the --cherrypick or
** --backout options are used only the changes associated with the
** single check-in VERSION are merged. The --backout option causes
** the changes associated with VERSION to be removed from the current
** checkout rather than added.
**
** If the VERSION argument is omitted, then Fossil attempts to find
** a recent fork on the current branch to merge.
**
** Only file content is merged. The result continues to use the
** file and directory names from the current checkout even if those
** names might have been changed in the branch being merged in.
**
** Other options:
**
** --baseline BASELINE Use BASELINE as the "pivot" of the merge instead
** of the nearest common ancestor. This allows
** a sequence of changes in a branch to be merged
** without having to merge the entire branch.
**
** --binary GLOBPATTERN Treat files that match GLOBPATTERN as binary
** and do not try to merge parallel changes. This
** option overrides the "binary-glob" setting.
**
** --case-sensitive BOOL Override the case-sensitive setting. If false,
** files whose names differ only in case are taken
** to be the same file.
**
** -f|--force Force the merge even if it would be a no-op.
**
** --force-missing Force the merge even if there is missing content.
**
** --integrate Merged branch will be closed when committing.
**
** -n|--dry-run If given, display instead of run actions
**
** -v|--verbose Show additional details of the merge

** COMMAND: update
**
** Usage: %fossil update ?OPTIONS? ?VERSION? ?FILES...?
**
** Change the version of the current checkout to VERSION. Any
** uncommitted changes are retained and applied to the new checkout.
**
** The VERSION argument can be a specific version or tag or branch
** name. If the VERSION argument is omitted, then the leaf of the
** subtree that begins at the current version is used, if there is
** only a single leaf. VERSION can also be "current" to select the
** leaf of the current version or "latest" to select the most recent
** check-in.
**
** If one or more FILES are listed after the VERSION then only the
** named files are candidates to be updated, and any updates to them
** will be treated as edits to the current version. Using a directory
** name for one of the FILES arguments is the same as using every
** subdirectory and file beneath that directory.
**
** If FILES is omitted, all files in the current checkout are subject
** to being updated and the version of the current checkout is changed
** to VERSION. Any uncommitted changes are retained and applied to the
** new checkout.
**
** The -n or --dry-run option causes this command to do a "dry run".
** It prints out what would have happened but does not actually make
** any changes to the current checkout or the repository.
**
** The -v or --verbose option prints status information about
** unchanged files in addition to those file that actually do change.
**
** Options:
** --case-sensitive <BOOL> override case-sensitive setting
** --debug print debug information on stdout
** --latest acceptable in place of VERSION, update to latest version
** --force-missing force update if missing content after sync
** -n|--dry-run If given, display instead of run actions
** -v|--verbose print status information about all files
** -W|--width <num> Width of lines (default is to auto-detect). Must be >20
** or 0 (= no limit, resulting in a single line per entry).
**
** See also: revert
