parse_ident():

  Modern linuxen seem to use an OS/ABI of '0', believing that it means "Unix - SYSTEM V".
go():
  parse_note() appears to make assumptions about the prstatus and psinfo structs that do not apply to the "GNU" branded system (i.e. linux).
__main__:
  assign the results of go() to globals
