=head1 CONFIGURATION FILE

The configuration file must have a INI format, which is supported by the L<Config::IniFile> module.

Here is an example of the required parameters with a description:

    [GENERAL]
    # the Siebel Gateway hostname and port, for example
    gateway=foobar:1055
    # the Siebel Enterprise name
    enterprise=MyEnterprise
    # the Siebel user with administrative privileges
    user=sadmin
    # the password from the user with administrative privileges
    password=123456
    # the field delimiter used to separate the output fields of srvrmgr
    field_delimiter=|
    # the complete pathname to the program srvrmgr
    srvrmgr= /foobar/bin/srvrmgr
    # if true, will add a "load preferences" command with "LoadPreferences" action automatically
    load_prefs = 1
    # type defines which subclass of Siebel::Srvrmgr::Daemon to use. The acceptable value is "heavy" 
    # for Siebel::Srvrmgr::Daemon::Heavy and "light" for Siebel::Srvrmgr::Daemon::Light
    type = heavy

Whatever other parameters or sections available on the same INI will be ignored by this class, but you can subclass it and use
any other parameters/section you may want to.

Please refer to the Pod of L<Siebel::Srvrmgr::Daemon> and corresponding subclasses to understand what parameters are optional or not.
