>This method takes one parameter, the name of a method
implemented by the XML-RPC server.</P
><P
>It returns an array of possible signatures for this
method. A signature is an array of types. The first of these
types is the return type of the method, the rest are parameters.</P
><P
>Multiple signatures (ie. overloading) are permitted: this is
the reason that an array of signatures are returned by this
method.</P
><P
>Signatures themselves are restricted to the top level
parameters expected by a method. For instance if a method
expects one array of structs as a parameter, and it returns a
string, its signature is simply "string, array". If it expects
three integers, its signature is "string, int, int,
int".</P
><P
> If no signature is defined for the method, a none-array value is
returned. Therefore this is the way to test for a non-signature,
