// This file contains both code to deal with invoking "external" functions, but
// also contains code that implements "exported" external functions.
//
-// External functions in LLI are implemented by dlopen'ing the lli executable
-// and using dlsym to look op the functions that we want to invoke. If a
-// function is found, then the arguments are mangled and passed in to the
-// function call.
+// External functions in the interpreter are implemented by
+// using the system's dynamic loader to look up the address of the function
+// we want to invoke. If a function is found, then one of the
+// many lle_* wrapper functions in this file will translate its arguments from
+// GenericValues to the types the function is actually expecting, before the
+// function is called.
