There is a hidden feature in the compiler, which I added in order to
keep compiled code smaller. It is a special proclamation
(proclaim '(si::c-export-fname foo))
(defun foo (x)
By compiling the code above you get a publicly defined mypLfoo() C
function which you can call. This is undocumented I cannot assure that
it will stay like that because I do not like it that much.

That's it. I am sorry I did not document this keyword argument, which is
*required* in order to produce standalone executables and libraries.
