+#   Search is: case-insensitive, space, tabs, or nothing around '=', and one or more # in each placeholder.
+#   Replace is: performed in-place inside of file; however, a backup (.bak) of the original file is also made.  
+#
+# NOTE: sed on Mac doesn't include a case-insensitive option.  To keep the search pattern equivalent for both
+#       grep and sed, must use an expanded pattern for text where each letter is expressed in both upper/lower case.
+#       ex: Ver should be [vV][eE][rR]
