+Shell scripts are the recommended choice for ZEDLETs that mostly call
+other utilities and do relatively little data manipulation.
+
+Shell scripts MUST work on both bash and dash.
+
+Shell scripts MUST run cleanly through ShellCheck:
+  http://www.shellcheck.net/
+
+General functions reside in "zed-functions.sh".  Use them where applicable.
