+External Configuration Properties
+=================================
+Below values can be overridden when invoking gradle build using property arguments, for example:
+
+./gradlew build -Pversion=2.0
+
+                  group => The group ID
+                version => The version
+       targetJreVersion => Version number assigned to sourceCompatibility and targetCompatibility
+          nuixEngineDir => Overrides value to engine release otherwise pulled from ENV var NUIX_ENGINE_DIR
+                tempDir => Used to override temp directory for testing which would otherwise default to dir in localappdata
+            testDataDir => Directory tests can load test data they depend on from
+  rubyExamplesDirectory => Directory containing Ruby script files used to test various aspects from scripting
+testOutputDirectoryRoot => Root directory where tests may write data while running.  Each test run will create a timestamp subdirectory
+           nuixUsername => Username used to authenticate with CLS (Cloud License Server).  Otherwise, would be pulled from ENV var NUIX_USERNAME
+           nuixPassword => Password used to authenticate with CLS (Cloud License Server).  Otherwise, would be pulled from ENV var NUIX_PASSWORD
