       This tool is just a front end for the DBI::ProxyServer
       package. All it does is picking options from the command
       line and calling DBI::ProxyServer::main(). See the
       DBI::ProxyServer(3) manpage for details.

       Available options include:

       ----cchhrroooott==ddiirr
           (UNIX only)  After doing a bind(), change root
           directory to the given directory by doing a chroot().
           This is usefull for security, but it restricts the
           environment a lot. For example, you need to load DBI
           drivers in the config file or you have to create hard
           links to Unix sockets, if your drivers are using them.
           For example, with MySQL, a config file might contain
           the following lines:

               my $rootdir = '/var/dbiproxy';
               my $unixsockdir = '/tmp';
               my $unixsockfile = 'mysql.sock';
               foreach $dir ($rootdir, "$rootdir$unixsockdir") {
                   mkdir 0755, $dir;
               }
               link("$unixsockdir/$unixsockfile",
                    "$rootdir$unixsockdir/$unixsockfile");
               require DBD::mysql;

               {
                   'chroot' => $rootdir,
                   ...
               }

           If you don't know chroot(), think of an FTP server
           where you can see a certain directory tree only after
           logging in. See also the --group and --user options.

       ----ccoonnffiiggffiillee==ffiillee
           Config files are assumed to return a single hash ref
           that overrides the arguments of the new method.
           However, command line arguments in turn take
           precedence over the config file. See the the section
           on CONFIGURATION FILE section below for details on the
           config file.

       ----ddeebbuugg
           Turn debugging mode on. Mainly this asserts that
           logging messages of level "debug" are created.

       ----ffaacciilliittyy==mmooddee
           (UNIX only) Facility to use for the section on
           Sys::Syslog (3). The default is ddaaeemmoonn.

       ----ggrroouupp==ggiidd
           After doing a bind(), change the real and effective
           GID to the given.  This is usefull, if you want your
           server to bind to a privileged port (<1024), but don't
           want the server to execute as root. See also the
           --user option.

           GID's can be passed as group names or numeric values.

       ----llooccaallaaddddrr==iipp
           By default a daemon is listening to any IP number that
           a machine has. This attribute allows to restrict the
           server to the given IP number.

       ----llooccaallppoorrtt==ppoorrtt
           This attribute sets the port on which the daemon is
           listening. It must be given somehow, as there's no
           default.

       ----llooggffiillee==ffiillee
           Be default logging messages will be written to the
           syslog (Unix) or to the event log (Windows NT). On
           other operating systems you need to specify a log
           file. The special value "STDERR" forces logging to
           stderr. See the Net::Daemon::Log(3) manpage for
           details.

       ----mmooddee==mmooddeennaammee
           The server can run in three different modes, depending
           on the environment.

           If you are running Perl 5.005 and did compile it for
           threads, then the server will create a new thread for
           each connection. The thread will execute the server's
           Run() method and then terminate. This mode is the
           default, you can force it with "--mode=threads".

           If threads are not available, but you have a working
           fork(), then the server will behave similar by
           creating a new process for each connection.  This mode
           will be used automatically in the absence of threads
           or if you use the "--mode=fork" option.

           Finally there's a single-connection mode: If the
           server has accepted a connection, he will enter the
           Run() method. No other connections are accepted until
           the Run() method returns (if the client disconnects).
           This operation mode is usefull if you have neither
           threads nor fork(), for example on the Macintosh. For
           debugging purposes you can force this mode with
           "--mode=single".

       ----ppiiddffiillee==ffiillee
           (UNIX only) If this option is present, a PID file will
           be created at the given location.

       ----uusseerr==uuiidd
           After doing a bind(), change the real and effective
           UID to the given.  This is usefull, if you want your
           server to bind to a privileged port (<1024), but don't
           want the server to execute as root. See also the
           --group and the --chroot options.

           UID's can be passed as group names or numeric values.

       ----vveerrssiioonn
           Supresses startup of the server; instead the version
           string will be printed and the program exits
           immediately.
