4 % DESCRIPTION: NEWCONNECTION makes a new managed repository connection.
5 %
6 % CALL: conn = rm.newConnection(pl);
7 % conn = rm.newConnection('hostname');
8 % conn = rm.newConnection('hostname', 'database');
9 % conn = rm.newConnection('hostname', 'database', 'username');
10 % conn = rm.newConnection('hostname', 'database', 'username', 'password');
11 %
12 % If all required connection fields are input, the connection will be
13 % silently created and added to the manager. Otherwise, a connection dialog
14 % will be presented and the resulting connection added to the manager.
