-A recommmended dependency of this script is my other repo named "errhandle",
-which prints stack trace on error, and calls a cleanup function:
-https://iankelling.org/git/?p=errhandle, set ERRHANDLE_PATH, or put it
-in a directory adjacent to the absolute, resolved directory this file is
-in.
+This script has a dependency which you can download manually or it
+will be automatically downloaded into the same directory.
+It handles errors by printing stack trace and and cleaning up the namespaces.
+To download manually,
+git clone https://iankelling.org/git/errhandle
+into an adjacent directory, or
+export ERRHANDLE_PATH to point to the 'err' file in that repo.
