-Only include files with the hastodos tag.
-This section is contributed from [[https://gist.github.com/d12frosted/a60e8ccb9aceba031af243dff0d19b2e][d12frosted]] and use his vulpea.el package's functions.
-I ripped out the essentials because I don't want all the other stuff in that package.

+Now, of course, this code is not useful as it is--after all, we can't tangle a ~.sh~ script into [[file:config.el]].
 
+*** Adding results to agenda files
+The rubber hits the road here.
+I'll call that shell command to set the agenda files correctly.
