+## lintcheck
+`cargo lintcheck` will build and run clippy on a fixed set of crates and generate a log of the results.  
+You can `git diff` the updated log against its previous version and 
+see what impact your lint made on a small set of crates.  
+If you add a new lint, please audit the resulting warnings and make sure 
+there are no false positives and that the suggestions are valid.
+
+Refer to the tools [README] for more details.
