 Installs the syslog_ng package and optional packages which may provide additional functionalities.
 
 ``syslog_ng.config``
------------------
-This state manages the file ``syslog_ng.conf`` under ``/etc`` (template found in "syslog_ng/files"). The configuration is populated by values in "syslog_ng/map.jinja" based on the package's default values (and RedHat, Debian, Suse and Arch family distribution specific values), which can then be overridden by values of the same name in pillar.
