+How can i check the plugin version ?
+------------------------------------
+
+You can check the version of plugins and modes with option ``--version``:
+::
+
+  $ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --version
+  Plugin Version: 0.1
+  $ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=storage --version
+  Mode Version: 1.0
+
+You can also use the option ``--mode-version`` to execute the mode only if there is the good version.
+For example, we want to execute the mode only if the version >= 2.x:
+
+  $  perl  centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=storage --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --verbose --mode-version='2.x'
+  UNKNOWN: Not good version for plugin mode. Excepted at least: 2.x. Get: 1.0
