 * **Rule #4:** provide a metadata header with syntax, description, author, source, and license
 * **Rule #5:** prefer command-line options, else ask the user
 * **Rule #6:** the encoding of the script is in UTF-8 with BOM to support Unicode characters
-* **Rule #7:** exits 0 for success, else print an error message and exit with the error code (mostly 1)
+* **Rule #7:** use 'Set-StrictMode -Version Latest' to enable additional error checking
