-I use this for a lot of scripts in this repo, when:
-
--   I don't want to set up a requirements.txt file for each script
-    (and it wouldn't be accurate anyway)
-
--   I might go a long time between writing and running a script, and
-    a third-party library might upgrade in the meantime -- and then it's
-    useful to know what I originally used if the script breaks
-
--   I don't want to retest every script every time I upgrade a library.
