for some time now pcb-rnd has had user configurable CAM exporters,  to
allow customised exporting for different fabs and workflows.

see also

http://repo.hu/cgi-bin/pool.cgi?cmd=show&node=cam

the lead dev is able to implement support for user configurable pre and
post gcode headers and footers pretty quickly,  but would need someone
willing to build pcb-rnd and the support library librnd from svn head to
test the implementation in production.

The code just needs to be modified to support a header and footer in an
optional, plugin specific config file.

I have included the lead developer in the cc:, so, if you are keen to see
this feature supported and are willing to build and test, let him know.

regards,

Erich
