<para>This function, if defined, will be called by
Conky at shutdown or when the configuration is
reloaded. Use this hook to clean up after yourself,
such as freeing memory which has been allocated by
external libraries via Lua. Conky puts 'conky_' in
front of function_name to prevent accidental calls to
the wrong function unless you put you place 'conky_' in
front of it yourself.</para>
