Hi everybody.

Nice project, love.it

By the way, I´ve been working months with ansible and I´m having trouble debugging an action module, I tried to call the vv function that is supossed to dump messages to the logger but they don´t appear in the screen.

I have been searching for hours for something that enables logging from the module but didn´t find any.

Thanx in advance.

Jorge

for vv to display output, you need to run ansible with -vv (for vvv  
-vvv and so on), this will work for action plugins but not for task  
plugins/modules/library as those only can return 1 output instance in  
json format to ansible.
