  18 ## ChangeLog.
  19 #
  20 #= Version 0.4:
  21 #
  22 # - Build the final system using real cores (instead of threads,
  23 #   if possible) to try to guarantee an error-free compilation.
  24 #   Instructions taken from https://stackoverflow.com/questions/6481005/how-to-obtain-the-number-of-cpus-cores-in-linux-from-the-command-line
  25 #
  26 #= Version 0.3:
  27 #
  28 # - Use the -f (force) option when building on 'phase-1'.
  29 #
  30 #= Version 0.2:
  31 #
  32 # - Switch /bin/sh to /bin/bash for catching errors on pipes.
  33 #
  34 # - Upgrade packages on 'phase-2' to ensure no dependency on
  35 #   /tools (temporary system) or to ensure possible system
  36 #   breaks by cutting symbolic links using qi/graft.
  37 #
  38 #= Version 0.1:
  39 #
  40 # - Initial version.
