title: Regarding license of plink/pscp/awk
body: <p>My Windows application uses PLINK/PSCP and awk, and it just uses those binary out side of the Application. Just calling.
  I see PLINK/PSCP is under MIT license, so no issue to use that, and no need to make my App public.
  What about awk utility?
  Is it Reciprocal license which should be opened in public?</p>
  
  <p>Thanks.</p>
