Platform: GNU/Linux/i386

Hello,

Would it be very difficult to implement the possibility to change regions in a single ps.map instruction file ? This would allow creating layouts with several maps, such as one of a large region and one of a zoom in one single run. Right now I have to create two ps.map instruction files, run them separately and change region in between, and then put them together in a drawing program.

Maybe a "simple"(?) ps.map element allowing to launch a system command could be a  solution ? But this obviously depends on how binding the order of commands in ps.map is. Otherwise, adding a "region" element to the individual map commands, such as:

vareas MyMap1
  region XXX
end
vareas MyMap
  region YYY
end
