yaz-json-parse is a utility which demonstrates the JSON API of YAZ. (yaz/json.h).
The program attempts to parse a JSON from standard input (stdin). It will return exit code 1 if parsing fails and the parsing error message will be printed to standard error (stderr). The program returns exit code 0 if parsing succeeds, and returns no output unless -p is given (see below).
Makes the JSON parser echo the JSON result string to standard output, if parsing from stdin was successful. If -p is given twice, then the output is a multi-line output with indentation (pretty print).
