**
** 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.
**
** The REPOSITORY can be a directory (aka folder) that contains one or
** more repositories with names ending in ".fossil".  In this case, the
** a prefix of the URL pathname is used to search the directory for an
** more repositories with names ending in ".fossil".  In this case, a
** prefix of the URL pathname is used to search the directory for an
** appropriate repository.  To thwart mischief, the pathname in the URL must
** contain only alphanumerics, "_", "/", "-", and ".", and no "-" may
** occur after "/", and every "." must be surrounded on both sides by
** alphanumerics.  Any pathname that does not satisfy these constraints
** results in a 404 error.  Files in REPOSITORY that match the comma-separated
** list of glob patterns given by --files and that have known suffixes
** such as ".txt" or ".html" or ".jpeg" and do not match the pattern
** "*.fossil*" will be served as static content.  With the "ui" command,
** the REPOSITORY can only be a directory if the --notfound option is
** also present.
**
** By default, the "ui" command provides full administrative access without
** having to log in.  This can be disabled by turning off the "localauth"
** setting.  Automatic login for the "server" command is available if the
** --localauth option is present and the "localauth" setting is off and the
** connection is from localhost.  The "ui" command also enables --repolist
** by default.
**
** Options:
**   --baseurl URL       Use URL as the base (useful for reverse proxies)
**   --create            Create a new REPOSITORY if it does not already exist
**   --files GLOBLIST    Comma-separated list of glob patterns for static files
**   --localauth         enable automatic login for requests from localhost
**   --localhost         listen on 127.0.0.1 only (always true for "ui")
**   --nojail            Drop root privileges but do not enter the chroot jail
**   --notfound URL      Redirect
**   -P|--port TCPPORT   listen to request on port TCPPORT
**   --th-trace          trace TH1 execution (for debugging purposes)
