Status of the CVS tree

Just to be clear (I realise I've forget to be precise on this point):
- the Head of CVS is version 2.2.1 (and the current evolution)
- branch version-2-1 is the former version 2, all new API (MCP class name prefix) but still the messy ProjectBuilder project organisation.
- branch version-1 is the old API (SMySQL class name prefix).

If you are new to SMySQL... PLEASE use the head (version 2.2.1 at present).
