## Summary:

              ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
               CODE-CELLS.EL — LIGHTWEIGHT NOTEBOOKS IN EMACS
              ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━


  This package lets you efficiently navigate, edit and execute code split
  into cells according to certain magic comments.  If you have [Jupytext]
  or [Pandoc] installed, you can also open ipynb notebook files directly
  in Emacs.  They will be automatically converted to a script for editing,
  and converted back to notebook format when saving.

  By default, three styles of comments are recognized as cell boundaries:

  ┌────
  │ # In[<number>]:
  │ 
  │ # %% Optional title
  │ 
  │ #* Optional title
  └────
