     22 ;;; Commentary:
     23 
     24 ;; Just a tiny package to insert dates.  I version all my elisp
     25 ;; packages as "%Y.%m.%d" and wanted to quickly insert that in the
     26 ;; magit tag prompt.
     27 
     28 ;; Another similar package is `insert-time'[1] but I found it too
     29 ;; limited, as it only supports inserting four (setq-able) formats.
     30 
     31 ;; No customizations are supported, I don't find it necessary because
     32 ;; I'm the only person using this package.
