+ Used by the `aquaero' plugin. Currently, the `libaquaero5' library, which
+ is used by the `aerotools-ng' toolkit, is not compiled as a shared object
+ nor does it feature an installation routine. Therefore, you need to point
+ collectd's configure script at the source directory of the `aerotools-ng'
+ project.
