/*
** COMMAND: settings
** COMMAND: unset*
**
** Usage: %fossil settings ?PROPERTY? ?VALUE? ?OPTIONS?
**    or: %fossil unset PROPERTY ?OPTIONS?
**
** The "settings" command with no arguments lists all properties and their
** values.  With just a property name it shows the value of that property.
** With a value argument it changes the property for the current repository.
**
** Settings marked as versionable are overridden by the contents of the
** file named .fossil-settings/PROPERTY in the check-out root, if that
** file exists.
**
** The "unset" command clears a property setting.
**
**
**    access-log       If enabled, record successful and failed login attempts
**                     in the "accesslog" table.  Default: off
**
**    admin-log        If enabled, record configuration changes in the
**                     "admin_log" table.  Default: off
**
**    allow-symlinks   If enabled, don't follow symlinks, and instead treat
**     (versionable)   them as symlinks on Unix. Has no effect on Windows
**                     (existing links in repository created on Unix become
**                     plain-text files with link destination path inside).
**                     Default: on (Unix), off (Windows)
**
**    auto-captcha     If enabled, the Login page provides a button to
**                     fill in the captcha password.  Default: on
**
**    auto-hyperlink   Use javascript to enable hyperlinks on web pages
**                     for all users (regardless of the "h" privilege) if the
**                     User-Agent string in the HTTP header look like it came
**                     from real person, not a spider or bot.  Default: on
**
**    auto-shun        If enabled, automatically pull the shunning list
**                     from a server to which the client autosyncs.
**                     Default: on
**
**    autosync         If enabled, automatically pull prior to commit
**                     or update and automatically push after commit or
**                     tag or branch creation.  If the value is "pullonly"
**                     then only pull operations occur automatically.
**                     Default: on
**
**    autosync-tries   If autosync is enabled setting this to a value greater
**                     than zero will cause autosync to try no more than this
**                     number of attempts if there is a sync failure.
**                     Default: 1
**
**    binary-glob      The VALUE is a comma or newline-separated list of
**     (versionable)   GLOB patterns that should be treated as binary files
**                     for committing and merging purposes.  Example: *.jpg
**
**    case-sensitive   If TRUE, the files whose names differ only in case
**                     are considered distinct.  If FALSE files whose names
**                     differ only in case are the same file.  Defaults to
**                     TRUE for unix and FALSE for Cygwin, Mac and Windows.
**
**    clean-glob       The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "clean" command will
**                     delete without prompting or allowing undo.
**                     Example: *.a,*.lib,*.o
**
**    clearsign        When enabled, fossil will attempt to sign all commits
**                     with gpg.  When disabled (the default), commits will
**                     be unsigned.  Default: off
**
**    crlf-glob        A comma or newline-separated list of GLOB patterns for
**     (versionable)   text files in which it is ok to have CR, CR+LF or mixed
**                     line endings. Set to "*" to disable CR+LF checking.
**                     The crnl-glob setting is a compatibility alias.
**
**    default-perms    Permissions given automatically to new users.  For more
**                     information on permissions see Users page in Server
**                     Administration of the HTTP UI. Default: u.
**
**    diff-binary      If TRUE (the default), permit files that may be binary
**                     or that match the "binary-glob" setting to be used with
**                     external diff programs.  If FALSE, skip these files.
**
**    diff-command     External command to run when performing a diff.
**                     If undefined, the internal text diff will be used.
**
**    dont-push        Prevent this repository from pushing from client to
**                     server.  Useful when setting up a private branch.
**
**    dotfiles         Include --dotfiles option for all compatible commands.
**     (versionable)
**
**    editor           Text editor command used for check-in comments.
**
**    empty-dirs       A comma or newline-separated list of pathnames. On
**     (versionable)   update and checkout commands, if no file or directory
**                     exists with that name, an empty directory will be
**                     created.
**
**    encoding-glob    The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "commit" command will
**                     ignore when issuing warnings about text files that may
**                     use another encoding than ASCII or UTF-8. Set to "*"
**                     to disable encoding checking.
**
**    exec-rel-paths   When executing certain external commands (e.g. diff and
**                     gdiff), use relative paths.
**
**    gdiff-command    External command to run when performing a graphical
**                     diff. If undefined, text diff will be used.
**
**    gmerge-command   A graphical merge conflict resolver command operating
**                     on four files.
**                     Ex: kdiff3 "%baseline" "%original" "%merge" -o "%output"
**                     Ex: xxdiff "%original" "%baseline" "%merge" -M "%output"
**                     Ex: meld "%baseline" "%original" "%merge" "%output"
**
**    hash-digits      The number of hexadecimal digits of the SHA1 hash to
**                     display.  (Default: 10; Minimum: 6)
**
**    http-port        The TCP/IP port number to use by the "server"
**                     and "ui" commands.  Default: 8080
**
**    https-login      Send login credentials using HTTPS instead of HTTP
**                     even if the login page request came via HTTP.
**
**    ignore-glob      The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "add", "addremove",
**                     "clean", and "extra" commands will ignore.
**                     Example:  *.log customCode.c notes.txt
**
**    keep-glob        The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "clean" command will
**                     keep.
**
**    localauth        If enabled, require that HTTP connections from
**                     127.0.0.1 be authenticated by password.  If
**                     false, all HTTP requests from localhost have
**                     unrestricted access to the repository.
**
**    main-branch      The primary branch for the project.  Default: trunk
**
**    manifest         If set to a true boolean value, automatically create
**     (versionable)   files "manifest" and "manifest.uuid" in every checkout.
**                     Optionally use combinations of characters 'r'
**                     for "manifest", 'u' for "manifest.uuid" and 't' for
**                     "manifest.tags".  The SQLite and Fossil repositories
**                     both require manifests.  Default: off.
**
**    max-loadavg      Some CPU-intensive web pages (ex: /zip, /tarball, /blame)
**                     are disallowed if the system load average goes above this
**                     value.  "0.0" means no limit.  This only works on unix.
**                     Only local settings of this value make a difference since
**                     when running as a web-server, Fossil does not open the
**                     global configuration database.
**
**    max-upload       A limit on the size of uplink HTTP requests.  The
**                     default is 250000 bytes.
**
**    mtime-changes    Use file modification times (mtimes) to detect when
**                     files have been modified.  (Default "on".)
**
**    mv-rm-files      If enabled (and Fossil was compiled with legacy "mv/rm"
**                     support), the "mv" and "rename" commands will also move
**                     the associated files within the checkout -AND- the "rm"
**                     and "delete" commands will also remove the associated
**                     files from within the checkout.  Default: off.
**
**    pgp-command      Command used to clear-sign manifests at check-in.
**                     The default is "gpg --clearsign -o ".
**
**    proxy            URL of the HTTP proxy.  If undefined or "off" then
**                     the "http_proxy" environment variable is consulted.
**                     If the http_proxy environment variable is undefined
**                     then a direct HTTP connection is used.
**
**    relative-paths   When showing changes and extras, report paths relative
**                     to the current working directory.  Default: "on"
**
**    repo-cksum       Compute checksums over all files in each checkout
**                     as a double-check of correctness.  Defaults to "on".
**                     Disable on large repositories for a performance
**                     improvement.
**
**    self-register    Allow users to register themselves through the HTTP UI.
**                     This is useful if you want to see other names than
**                     "Anonymous" in e.g. ticketing system. On the other hand
**                     users can not be deleted. Default: off.
**


**    ssh-command      Command used to talk to a remote machine with
**                     the "ssh://" protocol.
**
**    ssl-ca-location  The full pathname to a file containing PEM encoded
**                     CA root certificates, or a directory of certificates
**                     with filenames formed from the certificate hashes as
**                     required by OpenSSL.
**                     If set, this will override the OS default list of
**                     OpenSSL CAs. If unset, the default list will be used.
**                     Some platforms may add additional certificates.
**                     Checking your platform behaviour is required if the
**                     exact contents of the CA root is critical for your
**                     application.
**
**    ssl-identity     The full pathname to a file containing a certificate
**                     and private key in PEM format. Create by concatenating
**                     the certificate and private key files.
**                     This identity will be presented to SSL servers to
**                     authenticate this client, in addition to the normal
**                     password authentication.
**
**    tcl              If enabled (and Fossil was compiled with Tcl support),
**                     Tcl integration commands will be added to the TH1
**                     interpreter, allowing arbitrary Tcl expressions and
**                     scripts to be evaluated from TH1.  Additionally, the Tcl
**                     interpreter will be able to evaluate arbitrary TH1
**                     expressions and scripts. Default: off.
**
**    tcl-setup        This is the setup script to be evaluated after creating
**     (versionable)   and initializing the Tcl interpreter.  By default, this
**                     is empty and no extra setup is performed.
**
**    th1-docs         WARNING: If enabled (and Fossil was compiled with TH1
**                     support for embedded documentation files), this allows
**                     embedded documentation files to contain arbitrary TH1
**                     scripts that are evaluated on the server.  If native
**                     Tcl integration is also enabled, this setting has the
**                     potential to allow anybody with check-in privileges to
**                     do almost anything that the associated operating system
**                     user account could do.  Extreme caution should be used
**                     when enabling this setting.  Default: off.
**
**    th1-hooks        If enabled (and Fossil was compiled with support for TH1
**                     hooks), special TH1 commands will be called before and
**                     after any Fossil command or web page. Default: off.
**
**    th1-setup        This is the setup script to be evaluated after creating
**     (versionable)   and initializing the TH1 interpreter.  By default, this
**                     is empty and no extra setup is performed.
**
**    th1-uri-regexp   Specify which URI's are allowed in HTTP requests from
**     (versionable)   TH1 scripts.  If empty, no HTTP requests are allowed
**                     whatsoever.  The default is an empty string.
**
**    uv-sync          If true, automatically send unversioned files as part
**                     of a "fossil clone" or "fossil sync" command.  The
**                     default is false, in which case the -u option is
**                     needed to clone or sync unversioned files.
**
**    web-browser      A shell command used to launch your preferred
**                     web browser when given a URL as an argument.
**                     Defaults to "start" on windows, "open" on Mac,
**                     and "firefox" on Unix.
**
** Options:
**   --global   set or unset the given property globally instead of
**              setting or unsetting it for the open repository only.
**
**   --exact    only consider exact name matches.
**
