Feature-Request: Debugging mode for external print handler Weasyprint

[noseshimself]

Under certainconditions problems can only be analyzed using the debug output of Weasyprint. As Kraft is erasing the temporary html file quite fast it's hard to catch it.

Please add an option to get the Weasyprint input file (and the command line parameters) or add "-v -d" to the parameters and record the debug output. Probably copying the temporary file to the PDF output directory might be easier.

Good idea. Thx.
