I need to remove this option from being shown. It is not present and there
is no plan to add it, because it is unnecessary.

OK. I will give some examples and show how to use the new features. Also,
I will suggest reading the section
11.3 Features and the %feature directive in the SWIG docs.
SWIG/Doc/Manual/Customization.html
Say, file: test.i
%module test
%feature("inline") sleep; //this will inline the sleep function
%feature("export"); //start exporting symbols
%feature("intern_function"); //start lispifying symbols
%include "test.cpp"
%feature("intern_function",""); //start lispifying symbols
%feature("intern_function","lispify"); //start lispifying symbols
int test1();
%feature("intern_function",""); //start lispifying symbols
%feature("export",""); //stop exporting symbols
The file test.cpp as:
void sleep(float t);
int APPTerminating;
void xyz();
And the output file will be:
(cl:declaim (cl:inline #.(swig-lispify "sleep" 'function)))
(cffi:defcfun ("sleep" #.(swig-lispify "sleep" 'function)) :void
(t_arg0 :float))
(cl:export '#.(swig-lispify "sleep" 'function))
(cffi:defcvar ("APPTerminating" #.(swig-lispify "APPTerminating" 'variable))
:int)
(cl:export 'APPTerminating)
(cffi:defcfun ("xyz" #.(swig-lispify "xyz" 'function)) :void)
(cl:export '#.(swig-lispify "xyz" 'function))
(cffi:defcfun ("test1" #.(lispify "test1" 'function)) :int)
(cl:export '#.(lispify "test1" 'function))
I have removed the SWIG wrapper code generated at the top of file.
What do you think about the feature name as 'intern_function'? I am
thinking that it should be `lispify_function' or at least there should
be an alternate with the same name.

I will next see what can be done about the above.
