[O] Exporting custom dynamic blocks

[Bernhard Schmitz]

Hi,

What is the canonical way of exporting custom dynamic blocks? Is there a 
mechanism similar to org-dblock-write: only for exporting dblocks? I cannot 
find any documentation on this.

To give a little background to my question: I am currently writing a conversion 
from deadlines/schedules/effort to pgf-gantt charts. This was discussed before 
on this list, but I couldn't find anyone actually implementing it.
Ideally I would like to create a custom dynamic block that contains the result 
of my parsing and computation, and then have a custom exporter for that dynamic 
block that creates the pgf-gantt code, so that I can later add exporters for 
other formats, e.g. html.

If there is no such mechanism, what is the best way of storing that pgf-gantt 
source code so that it gets integrated into latex export, but doesn't interfere 
with other exporters? Currently I'm simply writing the pgf-gantt code into the 
custom block, and this does get exported correctly to latex, but produces error 
boxes in html.

Regards,
Bernhard
