 /**
  * The functions in this namespace allow actions to be restricted based
  * on the URL they operate on (see the KAuthorized namespace in
  * KConfig).
  *
  * As with KAuthorized functions, the relevant settings are read from
  * the application's KSharedConfig instance, so actions can be disabled
  * on a per-application or global basis (by using the kdeglobals file).
  *
  * URLs can be matched based on protocol, host and path, and the
  * referring URL can be taken into account.
  *
  * URL-based restrictions are recorded using this syntax:
  * @verbatim
    [KDE URL Restrictions]
    rule_count=<N>
    rule_1=<action>,<referingURL_protocol>,<referingURL_host>,<referingURL_path>,<URL_protocol>,<URL_host>,<URL_path>,<enabled>
    ...
    rule_N=<action>,<referingURL_protocol>,<referingURL_host>,<referingURL_path>,<URL_protocol>,<URL_host>,<URL_path>,<enabled>
    @endverbatim
  *
  * The following standard actions are defined:
  *
  * - redirect: A common example is a web page redirecting to another web
  *             page.  By default, internet protocols are not permitted
  *             to redirect to the "file" protocol, but you could
  *             override this for a specific host, for example:
  *             @verbatim
                [KDE URL Restrictions]
                rule_count=1
                rule_1=redirect,http,myhost.example.com,,file,,,true
                @endverbatim
  * - list:     Determines whether a URL can be browsed, in an "open" or
  *             "save" dialog, for example.  If a user should only be
  *             able to browse files under home directory one could use:
  *             @verbatim
                [KDE URL Restrictions]
                rule_count=2
                rule_1=list,,,,file,,,false
                rule_2=list,,,,file,,$HOME,true
                @endverbatim
  *             The first rule disables browsing any directories on the
  *             local filesystem. The second rule then enables browsing
  *             the users home directory.
  * - open:     This controls which files can be opened by the user in
  *             applications. It also affects where users can save files.
  *             To only allow a user to open the files in his own home
  *             directory one could use:
  *             @verbatim
                [KDE URL Restrictions]
                rule_count=3
                  rule_1=open,,,,file,,,false
                  rule_2=open,,,,file,,$HOME,true
                  rule_3=open,,,,file,,$TMP,true
                @endverbatim
  *             Note that with the above, users would still be able to
  *             open files from the internet. Note also that the user is
  *             also given access to $TMP in order to ensure correct
  *             operation of KDE applications. $TMP is replaced with the
  *             temporary directory that KDE uses for this user.
  * - link:     Determines whether a URL can be linked to.
  *
  * Some remarks:
  * - empty entries match everything
  * - host names may start with a wildcard, e.g. "*.acme.com"
  * - a protocol also matches similar protocols that start with the same name,
  *   e.g. "http" matches both http and https. You can use "http!" if you only want to
  *   match http (and not https)
  * - specifying a path matches all URLs that start with the same path. For better results
  *   you should not include a trailing slash. If you want to specify one specific path, you can
  *   add an exclamation mark. E.g. "/srv" matches both "/srv" and "/srv/www" but "/srv!" only
  *   matches "/srv" and not "/srv/www".
