|
|
This module can be use to see information of running modules.
|
|
These information are logged in "logs/moduleInfo.log"
|
|
|
|
It can also try to manage them by killing inactive one.
|
|
However, it does not support mutliple occurence of the same module
|
|
(It will kill the first one obtained by get)
