-    - channel : channel name.  
-    If you set #{servername} to channel, the report will be sent to #servername channel.  
-    In the following example, the report will be sent to the #server1 and #server2.  
-    Be sure to create these channels before scanning.

-Use Systemd, Upstart or supervisord, daemontools...
-
-- How to Enable Automatic-Update of Vunerability Data.  
-Use job scheduler like Cron (with -last2y option).

-- How to cross compile
-    ```bash

-
-- Logging  
-Log wrote to under /var/log/vuls/
-
-- Debug  
-Run with --debug, --sql-debug option.
-
-- Ajusting Open File Limit  
-[Riak docs](http://docs.basho.com/riak/latest/ops/tuning/open-files-limit/) is awesome.
-
-- Does Vuls accept ssh connections with fish-shell or old zsh as the login shell?  
-No, Vuls needs a user on the server for bash login. see also [#8](/../../issues/8)
-
-- Windows  
-Use Microsoft Baseline Security Analyzer. [MBSA](https://technet.microsoft.com/en-us/security/cc184924.aspx)
