## 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.  Moreover, 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.

  boundaries:

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