    + now possible to build hbmk2 as a general build
      tool without special Harbour language/environment
      support.
      Still refers to Harbour in a few places in help,
      and there are lots of remaining 'hb' prefixes in
      various public spots.
      To build:
         -env:HBMK_GENERIC=yes -DHBMK_GENERIC -nulrdd @hbmk2.hbp -omk -hbl=${hb_outputname}.%{hb_lng}.hbl
