+  Notes on testing:
+
+  mvn -q exec:java -Dexec.mainClass=org.apache.commons.crypto.Crypto
+    - run a basic JNI test
+    -Djni.library.path=override default JNI library path (system dependent)
+    -Djni.library.name=override default JNI library name (libcrypto)
+
+  mvn -q exec:java -Dexec.mainClass=org.apache.commons.crypto.jna.OpenSslJna
+    - run a basic JNA test
+    -Djna.library.path=override default JNA library path (system dependent)
+    -Dcommons.crypto.OpenSslNativeJna=override default library name
+
+  Running examples (these are under the test tree, so need test scope):
+  mvn -q -Dexec.classpathScope=test -Dexec.mainClass=org.apache.commons.crypto.examples.CLASSNAME
+    where CLASSNAME is CipherByteArrayExample, CipherByteBufferExample, RandomExample, StreamExample
+  
+  Additional options
+  -Djna.debug_load - debug JNA loading
+  -Dcommons.crypto.debug - add some Commons Crypto debugging
