+This program reads a file containing function prototypes
+(like syscall_aix.go) and generates system call bodies.
+The prototypes are marked by lines beginning with "//sys"
+and read like func declarations if //sys is replaced by func, but:
+	* The parameter lists must give a name for each argument.
+	  This includes return parameters.
+	* The parameter lists must give a type for each argument:
+	  the (x, y, z int) shorthand is not allowed.
+	* If the return parameter is an error number, it must be named err.
+	* If go func name needs to be different than its libc name,
+	* or the function is not in libc, name could be specified
+	* at the end, after "=" sign, like
+	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
+
+
+This program will generate three files and handle both gc and gccgo implementation:
+  - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
+  - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
+  - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
+
+ The generated code looks like this
+
+zsyscall_aix_ppc64.go

+	 // Pointer Creation
+	 r1, e1 := callasyscall(...)
+	 // Type Conversion
