Usage: $PROG [-n|-p] [-o filename] [-s syscall.h] object ...
-n Create SYSCALL_NOERROR.
-p Create PSEUDO_NOERROR.
(also removes leading "_" on syscall name).
-o filename Output to filename.
-s syscall.h Header to #include instead of <sys/syscall.h>.
The CPP environment variable must be set
to the path to the C preprocessor.
