* Description:
|

*
|
||||
* This file contains the urlize plugin
|
||||
*
|
||||
* This plugin wraps the text output of another command (plugin)
|
||||
* in HTML <A> tags, thus displaying the plugin output in as a clickable link in
|
||||
* the Nagios status screen. The return status is the same as the invoked plugin.
