is an option for the first cell of a cell group that specifies whether the group should be tagged to be evaluated by the Wolfram Language kernel when the notebook that contains them is opened.

  • When you first save a notebook that contains initialization groups or cells, you have the option to make a parallel auto-generated .m package that contains only the contents of the initialization groups and cells. The package is by default automatically updated whenever the initialization groups or cells in the notebook are changed and saved again.
