|

Lists the layers, separated by spaces, recommended for
|
||||
use with this layer.
|
||||
Optionally, you can specify a specific layer version for a
|
||||
recommendation by adding the version to the end of the
|
||||
layer name.
|
||||
Here is an example:
|
||||
<literallayout class='monospaced'>
|
||||
LAYERRECOMMENDS_mylayer = "anotherlayer (=3)"
|
||||
</literallayout>
|
||||
In this previous example, version 3 of "anotherlayer" is
|
||||
compared against
|
||||
<filename>LAYERVERSION_anotherlayer</filename>.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
An error is produced if any dependency is missing or the
|
||||
version numbers (if specified) do not match exactly.
|
||||
This variable is used in the
|
||||
<filename>conf/layer.conf</filename> file and must be
|
||||
suffixed with the name of the specific layer (e.g.
|
||||
<filename>LAYERRECOMMENDS_mylayer</filename>).
