.SH "NAME"
\fBjose\-fmt\fR \- Converts JSON between serialization formats
.
.SH "SYNOPSIS"
\fBjose fmt\fR \fIOPTIONS\fR
.
.SH "OVERVIEW"
This \fBjose fmt\fR command provides a mechanism for building and parsing JSON objects from the command line\. It operates as a simple stack machine\. All commands operate on the TOP item of the stack and, occasionally, the PREV item of the stack\. Commands that require a specific type of value will indicate it in parentheses\. For example: "TOP (arr\.)"\.
.
.P
This program returns 0 on success or the index of the option which failed\.
