;;; Commentary:
;; Keyboard abbreviations used below:
;; C-x == Ctrl + x
;; M-x == Alt + x
;; How to use this helper?
;; 1. Run "git log --reverse 2021-04-25..master > tmp.md" (2021-04-25 is an example tag of a previous version)
;; 2. Copy the contents of template.md to the start of tmp.md
;; 3. Open Emacs. Type M-x load-file <ENTER>
;; 4. Enter in the path to rssbridge-log-helper.el then <ENTER>
;; 5. Type M-x find-file <ENTER>
;; 6. Enter the path to tmp.md then <ENTER>
;; 7. Type M-x rssbridge-log-transient-state <ENTER>
;; 8. You can now use the following shortcuts to organize the commits:
;; x: Delete commit
;; g: Copy as general change
;; n: Copy as new bridge
;; m: Copy as modified bridge
;; r: Copy as removed bridge
;; <any key>: Quit
;; 9. Once you are done with all the commits, type C-x then C-s
;; 10. Exit Emacs with C-x then C-c
