-*NestedText* is a file format for holding data that is to be entered, edited, or 
-viewed by people.  It allows data to be organized into a nested collection of 
-dictionaries, lists, and strings.  In this way it is similar to *JSON*, *YAML* 
-and *TOML*, but without the complexity and risk of *YAML* and without the 
-syntactic clutter of *JSON* and *TOML*.  *NestedText* is both simple and 
-natural.  Only a small number of concepts and rules must be kept in mind when 
-creating it.  It is easily created, modified, or viewed with a text editor and 
-easily understood and used by both programmers and non-programmers.
