+ o Build features:
+   - Tor's repository now includes a Travis Continuous Integration (CI)
+     configuration file (.travis.yml). This is meant to help new developers and
+     contributors who fork Tor to a Github repository be better able to test
+     their changes, and understand what we expect to pass. To use this new build
+     feature, you must fork Tor to your Github account, then go into the
+     "Integrations" menu in the repository settings for your fork and enable
+     Travis, then push your changes.
