      6 # maketars [-b] [-x] [-i installdir] [-a arch] [-m machine] [-s setsdir]
      7 #	[-M metalog] [-N etcdir] [-F setlistsdir] [-d destdir]
      8 #	[-t tardir] [-U] [setname ...]
      9 #
     10 # The default sets are "base comp debug dtb etc games gpufw man misc rescue tests text"
     11 # The X sets are "xbase xcomp xdebug xetc xfont xserver"
     12 #
     13 # If '-i installdir' is given, copy the given sets to installdir
     14 # (using pax -rw ...) instead of creating tar files.
     15 # In this case, remove "etc", and "xetc" from the list of default sets.
