** COMMAND: changes
** COMMAND: status
**
** Usage: %fossil changes|status ?OPTIONS? ?PATHS ...?
**
** Report the change status of files in the current check-out.  If one or
** more PATHS are specified, only changes among the named files and
** directories are reported.  Directories are searched recursively.
**
** The status command is similar to the changes command, except it lacks
** several of the options supported by changes and it has its own header
** and footer information.  The header information is a subset of that
** shown by the info command, and the footer shows if there are any forks.
** Change type classification is always enabled for the status command.
**
** Each line of output is the name of a changed file, with paths shown
** according to the "relative-paths" setting, unless overridden by the
** --abs-paths or --rel-paths options.
**
** By default, all changed files are selected for display.  This behavior
** can be overridden by using one or more filter options (listed below),
** in which case only files with the specified change type(s) are shown.
** As a special case, the --no-merge option does not inhibit this default.
** This default shows exactly the set of changes that would be checked-
** in by the commit command.
**
** If no filter options are used, or if the --merge option is used, the
** artifact hash of each merge contributor check-in version is displayed at
** the end of the report.  The --no-merge option is useful to display the
** default set of changed files without the merge contributors.
**

** change type classification is UPDATED_BY_MERGE or UPDATED_BY_INTEGRATE.
** If the file had to be merged with any other changes, it is considered
** to be merged or conflicted and therefore will be shown by --edited, not
** --updated, with types EDITED or CONFLICT.  The --changed option can be
** used to display the union of --edited and --updated.
**
** --differ is so named because it lists all the differences between the
** checked-out version and the check-out directory.  In addition to the
** default changes (excluding --merge), it lists extra files which (if
** ignore-glob is set correctly) may be worth adding.  Prior to doing a
** commit, it is good practice to check --differ to see not only which
** changes would be committed but also if any files should be added.
**
** If both --merge and --no-merge are used, --no-merge has priority.  The
** same is true of --classify and --no-classify.

** COMMAND: clean

** that are not officially part of the check-out.  If one or more PATH
** arguments appear, then only the files named, or files contained with

** permanent removal of each file.  Otherwise, files are backed up to the
** undo buffer prior to removal, and prompts are issued only for files
** whose removal cannot be undone due to their large size or due to

** Usage: %fossil login-group ?SUBCOMMAND? ?OPTIONS?
**
** Run various subcommands to manage login-group related settings of the open
** repository or of the repository identified by the -R or --repository option.
**
** >  fossil login-group ?-R REPO?
**
**     Show the login-group to which REPO, or if invoked from within a check-out
**     the repository on which the current check-out is based, belongs.
**
** >  fossil login-group join ?-R? REPO ?--name NAME?
**
**     This subcommand must be invoked from within a check-out to either: add
**     the open repository to the login group that REPO is a member, in which
**     case the optional "--name" argument is not required; or create a new
**     login group between the open repository and REPO, in which case the new
**     group NAME is determined by the mandatory "--name" option. REPO may be
**     specified with or without the -R flag.
**
** >  fossil login-group leave ?-R REPO?
**
**     Take the repository REPO, or if invoked from within a check-out the

**

** access any other group member as long as they have an entry in the USER

** Usage: %fossil server ?OPTIONS? ?REPOSITORY?

**
** Open a socket and begin listening and responding to HTTP requests on
** TCP port 8080, or on any other TCP port defined by the -P or
** --port option.  The optional REPOSITORY argument is the name of the
** Fossil repository to be served.  The REPOSITORY argument may be omitted
** if the working directory is within an open check-out, in which case the

**
** The "ui" command automatically starts a web browser after initializing
** the web server.  The "ui" command also binds to 127.0.0.1 and so will
** only process HTTP traffic from the local machine.
**
** If REPOSITORY is a directory name which is the root of a
** check-out, then use the repository associated with that check-out.
** This only works for the "fossil ui" command, not the "fossil server"
** command.
**
** If REPOSITORY begins with a "HOST:" or "USER@HOST:" prefix, then
** the command is run on the remote host specified and the results are
** tunneled back to the local machine via SSH.  This feature only works for

** COMMAND: merge
** COMMAND: cherry-pick
**
** Usage: %fossil merge ?OPTIONS? ?VERSION?
**
** The argument VERSION is a version that should be merged into the
** current check-out.  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
** check-out rather than added. When invoked with the name cherry-pick,
** this command works exactly like merge --cherrypick.
**
** 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 check-out even if those
** names might have been changed in the branch being merged in.
**
** Options:
**
**   --backout               Do a reverse cherrypick merge against VERSION.
**                           In other words, back out the changes that were
**                           added by VERSION.
**
**   --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.
**
**   --cherrypick            Do a cherrypick merge VERSION into the current
**                           check-out.  A cherrypick merge pulls in the changes
**                           of the single check-in VERSION, rather than all
**                           changes back to the nearest common ancestor.
**
**   -f|--force              Force the merge even if it would be a no-op.
**
**   --force-missing         Force the merge even if there is missing content.

** COMMAND: update
**
** Usage: %fossil update ?OPTIONS? ?VERSION? ?FILES...?
**
** Change the version of the current check-out to VERSION.  Any
** uncommitted changes are retained and applied to the new check-out.
**
** 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 check-out are subject
** to being updated and the version of the current check-out is changed
** to VERSION. Any uncommitted changes are retained and applied to the
** new check-out.
**
** 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 check-out 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
**   -n|--dry-run            If given, display instead of run actions
**   --force-missing         Force update if missing content after sync
**   -K|--keep-merge-files   On merge conflict, retain the temporary files
**                           used for merging, named *-baseline, *-original,
**                           and *-merge.
**   --latest                Acceptable in place of VERSION, update to
**                           latest version
**   --nosync                Do not auto-sync prior to update
**   --setmtime              Set timestamps of all files to match their
**                           SCM-side times (the timestamp of the last
**                           check-in which modified them).
**   -v|--verbose            Print status information about all files
**   -W|--width WIDTH        Width of lines (default is to auto-detect).
**                           Must be more than 20 or 0 (= no limit,
