Review Comment:
Ah, this should be:
```
usage() unless (($opt{'command'} && @{$opt{'command'}}) || $opt{'conf'}) &&
$opt{'vardir'}
```
breaking down `($opt{'command'} && @{$opt{'command'}})`:
- `$opt{'command'}` means "there is some value at `$opt{'command'}`
- we expect this to be an arrayref, so, `@{$opt{'command'}}` means "the
arrayref at `$opt{'command'}` is nonempty"
