Provide a script to dump Mapnik configuration of a layer

[strk]

It is useful for debugging to have a script that given a layer (UUID?) dumps the corresponding XML passed to mapnik for rendering.

Having such script would allow putting the XML in a standalone file and trying the mapnik tools for rendering it.

Or is a similar script already existing ?

There is currently no such script, but added simple console.log and dumping to /pile/tmp/layer_id-randomuuid.debug.xml (see here)

Currently yields:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Map[]>
