This module doesn't do much. It's not a tag module, and has no admin interface. This module is a simple wrapper around the nuSOAP classes. It provides a SOAP engine for CMS to fascilitate SOAP messages between a SOAP server and a SOAP client. This module can allow other modules to act as either servers or clients.
This module is not for use directly on a page, it is a tool to be used by other modules. If you are a module developer and want to do some SOAP module development for CMS Made Simple, you are encouraged to check out the nuSOAP project itself first. Look here: http://www.scottnichol.com/soap.htm
