+    Checkstyle configuration that checks the Google coding conventions from Google Java Style
+    that can be found at https://google.github.io/styleguide/javaguide.html with the following
+    modifications:
+
+     - Replaced com.google with org.torproject in import statement ordering
+       [CustomImportOrder].
+
+     - Relaxed requirement that catch parameters must be at least two
+       characters long [CatchParameterName].
+
+    Checkstyle is very configurable. Be sure to read the documentation at

+
+    To completely disable a check, just comment it out or delete it from the file.
