+Setup Helper:
+  CPK now has a place for your individual testing configuration.
+  That is, instead of hardcoding it in the Rakefile and test/connections files,
+  there is now a local/database_connections.rb file that is NOT in the
+  repository. Your personal DB information (username, password etc) can
+  be stored here without making it difficult to submit patches etc.
+
+Installation:
+  i)   cp locals/database_connections.rb.sample locals/database_connections.rb
+  ii)  For #{adapter} connection details see "Adapter Setup Helper" below.
+  iii) Rerun this task
+  
+#{error_msg_adapter_helper}
+  
+Current ENV:
+  #{ENV.inspect}
+        EOS

+Adapter Setup Helper:
+  To run #{adapter} tests, you need to setup your #{adapter} connections.
+  In your local/database_connections.rb file, within the ENV['cpk_adapter'] hash, add:
+      "#{adapter}" => { adapter settings }
+
+  That is, it will look like:
+    ENV['cpk_adapters'] = {
+      "#{adapter}" => {
+        :adapter  => "#{adapter}",
+        :username => "root",
+        :password => "root",
+        # ...
+      }
+    }.to_yaml
+        EOS
+      end
