+This example shows integration with scalariform plugin.
+Reformat executed on every `cbt compile` call, and affects only *.scala source files.
+You can provide your custom scalariform preferences in build via `scalariformPreferences`.
+To test formatting in action you can execute: `cbt breakFormatting` to break formatting
+and `cbt scalariformReformat` to get formatting back.
