   9 #        can also include that into your .bashrc etc.
  10 #        All paths in the file will be absolut.

  44 Now the necessary environment for the H316 build system
  45 has been set up.
  46
  47 You have one possibility:
  48 a) Source the h316rc file into your current shell!
  49
  50 Then you can run
  51                "make" or "make all"
  52 to build all the stuff inside. When make successfully finishes,
  53 you are ready to go.
  54
  55 Have a lot of fun and good luck!
  56 (You should have installed GNU make, GCC, bash and friends!)
