"""The make plugin is useful for building make based parts.
Make based projects are projects that have a Makefile that drives the
build.
This plugin uses the common plugin keywords as well as those for "sources".
For more information check the 'plugins' topic for the former and the
'sources' topic for the latter.
Additionally, this plugin uses the following plugin-specific keyword:
    - script:
      (string)
      Run the given script name.
    - bash-arguments:
      (list of strings)
      Pass the given parameters to the bash script.
