NAME
       json_pp - JSON::PP command utility

SYNOPSIS
	   json_pp [-v] [-f from_format] [-t to_format] [-json_opt options_to_json1[,options_to_json2[,...]]]

DESCRIPTION
       json_pp converts between some input and output formats (one of them is JSON).  This program was copied from json_xs
       and modified.

       The default input format is json and the default output format is json with pretty option.

OPTIONS
   -f
	   -f from_format

       Reads a data in the given format from STDIN.

       Format types:

       json
	   as JSON

       eval
	   as Perl code

   -t
       Writes a data in the given format to STDOUT.

       null
	   no action.

       json
	   as JSON

       dumper
	   as Data::Dumper

   -json_opt
       options to JSON::PP

       Acceptable options are:

	   ascii latin1 utf8 pretty indent space_before space_after relaxed canonical allow_nonref
	   allow_singlequote allow_barekey allow_bignum loose escape_slash indent_length

       Multiple options must be separated by commas:

	   Right: -json_opt pretty,canonical

	   Wrong: -json_opt pretty -json_opt canonical

   -v
       Verbose option, but currently no action in fact.

   -V
       Prints version and exits.

EXAMPLES
	   $ perl -e'print q|{"foo":"あい","bar":1234567890000000000000000}|' |\
	      json_pp -f json -t dumper -json_opt pretty,utf8,allow_bignum

	   $VAR1 = {
		     'bar' => bless( {
				       'value' => [
						    '0000000',
						    '0000000',
						    '5678900',
						    '1234'
						  ],
				       'sign' => '+'
				     }, 'Math::BigInt' ),
		     'foo' => "\x{3042}\x{3044}"
		   };

	   $ perl -e'print q|{"foo":"あい","bar":1234567890000000000000000}|' |\
	      json_pp -f json -t dumper -json_opt pretty

	   $VAR1 = {
		     'bar' => '1234567890000000000000000',
		     'foo' => "\x{e3}\x{81}\x{82}\x{e3}\x{81}\x{84}"
		   };
