NAME
       json - JSON parser

SYNOPSIS
       package require Tcl  8.4

       package require json  ?1.1.1?

       ::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.
