      # CodePipeline does NOT pull the .git dir from Github when it auto downloads the repo!  So, we
      # have to pull the repo manually; as we need the .git dir to later get the commit message.
      #
      # When CodePipeline initially pulls the repo it puts all the files of the branch into the 'src'
      # dir, *not* into a dir with the name of the repo!!!  When CodePipeline invokes Codebuild it sets
      # the initial current working dir as the 'src' dir.  To pull the repo manually:
      # 1) delete all the files that was auto downloaded by CodePipeline,
      # 2) cd to the parent dir of the 'src' dir,
      # 3) manually clone the repo INTO the 'src' dir,
      #   *CRITICAL* as CodePipeline looks for all the artifacts of the build in the 'src' dir!!!
      # 4) switch to the correct branch
