 ## Desired
 
 - project logo
+- if configuration for given FILE is empty,
+  report an error, see TODO in CLI main tests
+- rename `xrlint.cli.CliEngine` into `xrlint.cli.XRLint`
+  (with similar API as the `ESLint` class) and export it 
+  from `xrlint.all`. Value of `FILES` should be passed to
+  `verify_datasets()` methods.
 - use `RuleMeta.docs_url` in formatters to create links
 - implement xarray backend for xcube 'levels' format
   so can validate them too
-- rename `xrlint.cli.CliEngine` into `xrlint.cli.XRLint`
-  (with similar API as the `ESLint` class) and export it 
-  from `xrlint.all`
 - add some more tests so we reach 99% coverage
 - support rule op args/kwargs schema validation
 - support CLI option `--print-config FILE`, see ESLint
