+[description]
+[para]
+
+The [package json] package provides a simple Tcl-only library for parsing the
+JSON [uri http://www.json.org/] data exchange format as specified in RFC 4627
+[uri http://www.ietf.org/rfc/rfc4627.txt].
+
+There is some ambiguity in parsing JSON because JSON has type information that
+is not maintained by the Tcl conversion.  The [package json] package returns
+data as a Tcl [cmd dict].  Either the [package dict] package or Tcl 8.5 is
+required for use.
+
+[section COMMANDS]
+
+[list_begin definitions]

+[call [cmd ::json::json2dict] [arg txt]]

+Parse JSON formatted text [arg txt] into a Tcl dict and return the value.
