+A note on character set aliases
+-------------------------------
+
+  Hubbub uses an external mapping file to encode relationships between 
+  character set names. This is the "Aliases" file. A copy may be found at
+  test/data/Aliases. The path to this file is required when calling 
+  hubbub_initialise().
