<!--

    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].

     - Enabled suppression of warnings using annotations.

     - Added a check for unused imports [UnusedImports].

    Checkstyle is very configurable. Be sure to read the documentation at

    http://checkstyle.sf.net (or in your downloaded distribution).

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

    Authors: Max Vetrenko, Ruslan Diachenko, Roman Ivanov.
