+  -m <modulename>  Name of the module; f2py generates a Python/C API

+  -h <filename>    Write signatures of the fortran routines to file <filename>
+                   and exit. You can then edit <filename> and use it instead
+                   of <fortran files> for generating extension module source.
+                   If <filename> is stdout or stderr then the signatures are
