OpenersNotesSection(Spacer1)Details

Additional front end options determine the precise behavior of initialization groups when a notebook 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.
