There are three kinds of details collected: headers, notes, and footnotes. They are presented to the user in a way similar to the following: Header1: Value1 Header3: Value3 Header2: Value2 Header4: Value4 => This is first note => This is the second note The first footnote. The second footnote. Headers are supposed to display information which is regularly available, such as the load and temperature of the system. Notes contain eventual information, such as warnings of high temperatures, and low disk space. Finally, footnotes contain pointers to further information such as URLs. c s0 t t| ��� i | _g | _g | _g | _d| _d S )NF)�superr �__init__� _header_index�_headers�_notes� _footnotes� _plugin_error��self�� __class__� �;/usr/lib/python3/dist-packages/landscape/sysinfo/sysinfo.pyr ' s z SysInfoPluginRegistry.__init__c C s^ | j �|�}|dkr6t| j�| j |< | j�||f� n$|d7 }|| j |< | j�|||f� dS )aj Add a new information header to be displayed to the user. Header names can be repeated. Headers with value None are not returned by get_headers(), but they still allocate a position in the list.
