+/* This file defines an internal function for processing default arguments
+   with proxy classes.
+
+   There seems to be no straightforward way to write proxy functions
+   involving default arguments. For example :
+
+             def foo(arg1,arg2,*args):
+                     proxyc.foo(arg1,arg2,args)
+
+   This fails because args is now a tuple and SWIG doesn't know what to
+   do with it.
+
+   This file allows a different approach :
+
+            def foo(arg1,arg2,*args):
+                    proxyc.__call_defarg(proxyc.foo,(arg1,arg2,)+args)
+
+   Basically, we form a new tuple from the object, call this special
+   __call_defarg method and it passes control to the real wrapper function.
+   An ugly hack, but it works.
