Currently, ArcanistGeneratedLinter searches for a hard coded annotation '@generated' in the file being linted. If found, it will signal to stop all other linters applicable for that file.
However, a hard coded annotation is not sufficient and limits the usability of this linter to a point that other linters need to implement their own 'ignoreGenerated' option or leverage, if possible, the 'include'/'exclude' properties in .arclint to ignore such files.
It would be preferable to allow user to specify the annotation to match via .arclint and hence making this linter more useful in multi-linter configurations.
