`copefmt` is the copium code formatter for languages that don't have any better options.
`copefmt` read from stdin and writes to stdout by default.
```
echo '*[]{...,foo->,bar->{...,baz->}}' | copefmt
*[]{
}
```
But filenames can be provided as arguments.
```
copefmt --input data/simple.groq --output formatted_simple.groq
```
