## Usage
```
jc PARSER [OPTIONS]
COMMAND | jc PARSER [OPTIONS]
```
or
```
COMMAND | jc [OPTIONS] PARSER
```
or
```
jc [OPTIONS] COMMAND
```
`jc` accepts piped input from `STDIN` and outputs a JSON representation of the previous command's output to `STDOUT`. The JSON output can be compact or pretty formatted.
