Three levels of help are provided. If no command is specified then general help will be displayed. If a command is specified (e.g. `pgbackrest help backup`) then a full description of the command will be displayed along with a list of valid options. If an option is specified in addition to a command (e.g. `pgbackrest help backup type`) then a full description of the option as it applies to the command will be displayed.

## Command Options

### Display Help Option (`--help`)

example: --help
```

### Display Version Option (`--version`)

Display version.

```yaml
