__________________________________________________________________________________________________________________________________________________NAME
json - JSON parser
SYNOPSIS
package require Tcl 8.4
package require json ?1.1?
::json::json2dict txt
_________________________________________________________________DESCRIPTION
The json package provides a simple Tcl-only library for parsing the JSON http://www.json.org/ data exchange format as specified in RFC 4627
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 json package returns data as a Tcl dict. Either the dict package or Tcl 8.5 is required for use.
COMMANDS
::json::json2dict txt
Parse JSON formatted text txt into a Tcl dict and return the value.
EXAMPLES
An example of a JSON array converted to Tcl. A JSON array is returned as a single item with multiple elements.

{
"precision": "zip",
"Latitude": 37.7668,
"Longitude": -122.3959,
"Address": "",
"City": "SAN FRANCISCO",

"Zip": "94107",
"Country": "US"
},

An example of a JSON object converted to Tcl. A JSON object is returned as a multi-element list (a dict).
