I am using org-mode installed by the emacs package system: org-plus-contrib. I just updated it this morning:
Org mode version 9.2.6 (9.2.6-elpaplus @ /usr/share/emacs/27.0.50/lisp/org/)
I have no trouble, so far, running this template. If it is of interest, I am using this also in directories in my Dropbox folder, from my laptop and a desktop machine. I will investigate changes in the template parameters.
I am already thinking of another one, to capture a file listing and perhaps enable commenting. That last bit will stymy me. In fact it's all pretty much beyond me, for the moment. I saw a contributed org function to do something similar.
Anyway, for now, this template shows promise. It's already easier to save quick notes about an ongoing project. Before org-mode, I used steno.el, to good effect; org-mode, however, is lightyears beyond steno.
Thank you for the comments.
