+    Cracklib is useful in testing the 'strength' of a password that checks
+    length, use of upper and lower case and a check against the specified CrackLib
+    dictionary.  CrackLib will also give helpful diagnostic messages that will
+    help 'strengthen' the password.

+    <para>
+     This example shows how to open a CrackLib dictionary, test a given password,
