+
+This is a starter / template for writing Bash scripts.  It includes a
+few things:
+
+1. some Doxygen-style comments to start things off
+2. flags to protect us from undefined variables and failed commands
+3. a `SCRIPT_PATH` variable so we can reference where the script lives
+4. an error trap that prints the line where an error happens
+5. a stack dump when errors do happen
+6. a wrapper to allow us to source this script as if it was a library
+7. CLI parameter handling
+8. automagic help / usage generation
+
+The goal is to help write scripts that are safer, cleaner, more usable,
+more testable, and easier to debug.
