#### Allow Duplicate Recipes
If `allow-duplicate-recipes` is set to `true`, defining multiple recipes with the same name is not an error and the last definition is used. Defaults to `false`.
```make
set allow-duplicate-recipes
@foo:
echo foo
@foo:
echo bar
```
```sh
$ just foo
bar
```
#### Dotenv Load
If `dotenv-load` is `true`, a `.env` file will be loaded if present. Defaults to `true`.
