+# 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
+# func asyscall(...) (n int, err error) {
+# // Pointer Creation
+# r1, e1 := callasyscall(...)
+# // Type Conversion
+# // Error Handler
+# return
