+ (description "The files in this collection implement JSON
+encoders/decoders in JavaScript.
+
+@code{json2.js}: This file creates a JSON property in the global object, if
+there isn't already one, setting its value to an object containing a stringify
+method and a parse method. The @code{parse} method uses the @code{eval}
+method to do the parsing, guarding it with several regular expressions to
+defend against accidental code execution hazards. On current browsers, this
+file does nothing, preferring the built-in JSON object.
+
+@code{json_parse.js}: This file contains an alternative JSON @code{parse}
+function that uses recursive descent instead of @code{eval}.
+
+@code{json_parse_state.js}: This files contains an alternative JSON
+@code{parse} function that uses a state machine instead of @code{eval}.
+
+@code{cycle.js}: This file contains two functions, @code{JSON.decycle} and
+@code{JSON.retrocycle}, which make it possible to encode cyclical structures
+and DAGs in JSON, and to then recover them. This is a capability that is not
+provided by ES5. @code{JSONPath} is used to represent the links.")
