PERL/Mapscript postGIS examples?

[Stephen Davies]

Could somebody please send me or point me at an example of a 
PERL/Mapscript script that displays layers populated from a postGIS 
database and/or raster layers?
The following PERL/Mapscript  and map file generates an image containing 
only the copyright layer.
Exactly the same map file with mapserver invoked as CGI generates all 
layers.
(In both cases the extent is provided as args.
eg ./genpics q 1 jpg 139.5143351 -34.7459112 139.5278707 -34.7207064)

Cheers and thanks,
Stephen Davies
