    <summary>
      <para>
This class is the main entry point for libgda cliente applications.  It provides the way by which client applications open connections.
</para>
      <para>
Also provides a way to treat several connections as if they were only one (a connection pool), which allows applications to, for instance, commit / rollback a transaction in all the connections being managed by a unique Gda.Client object, or obtain the list of all tables in all opened connections.

The format of cnc_string is similar to PostgreSQL and MySQL connection strings. It is a ;-separated series of key=value pairs. Do not add extra whitespace after the ; separator. The possible keys depend on the provider, but these keys should work with all providers: USER, PASSWORD, HOST, DATABASE, PORT
