| * Utility to parse the config properties. |
| * |
| * bind - ip[:port] - defines the local bind address and port, it defaults to the network interface with the widest |
| * class (ie class A is wider than class B) on port 14820 and if that port in use it will try |
| * incrementing by one till a free port is found. |
| * |
| * multicast - groupip:port | off - defines if multicast discovery is used and if so what multicast ip group and port is used |
| * defaults to 224.5.12.10:51482. A value of off means multicast is disabled. |
| * |
| * wka - ip[:port] - a comma separated list of ip address and port for remote nodes in the domain group. The port defaults to 14820. |
| * |
| * userid - is the userid other nodes must use to connect to this domain group. The default is the default domain name. |
| * |
| * password - is the password other nodes must use to connect to this domain group. The default is 'tuscany'. |
| * |
| * client - true means this is an SCAClient call |
