+extIndent serves as a much more flexible alternative to the Sprig `indent`.
+
+It has 6 arguments (the last of which may be passed in via pipeline):
+
+	* levels: The level of indentation for the text. If less than or equal to `0`, `extIndent` just returns `<input>` as-is and NO-OPs otherwise.
+	* skipFirst: If true, skip indenting the first line. This is particularly handy if you like to visually align your function calls in your templates.
+	* skipEmpty: If true, do not add an indent to *empty* lines (where an "empty line" means "only has a linebreak").
+	* skipWhitespace: If true, do not add an indent to lines that *only* consist of whitespace (spaces, tabs, etc.) and a linebreak.
+	* indentString: The string to use as the "indent character". This can be any string, such as `" "`, `"\t"`, `"."`, `"|"`, `"=="` etc.
+					(In fact, if indentString is set to "\n" and levels is always set to 1, this function can even be used to doubelspace text!)
+	* input: The text to be indented. Because it is the last argument, `extIndent` works with pipelined text as well.
