[mapserver-users] Full CADRG and VPF support

[Alans]

Has anyone managed to get this to work, i.e. creating an index from an a.toc
file, or 
directly refering to an a.toc file in the map file? or is it necessary to
generate an index
from the image files directly, as seems to be specified by others?
